This was good, but I definitely would not call it a cookie, although it looks like one. It has a cake-like texture. The flavor is good though and it bakes nicely but if you are looking for a cookie-like texture, skip this recipe. I baked 2 pans: 1 was a 13x9 the other was 8x8. Thanks for sharing the recipe, Rosina!-12 Aug 2010

Delicious! I halved the ingredients and put it in an 8x8 pan, using 1/3 c. egg whites instead of an egg. Like a chocolate chip cookie cake! Yum! Will probably make again!-19 Aug 2010

Birthday Cake Chocolate Chip Cookies

These Birthday Cake Chocolate Chip Cookies will make you want to celebrate your birthday all year! They’re made with cake mix and loaded with chocolate & birthday cake Oreos!

GIANT Single-Serving Birthday Cake Oreo Cookies

I am a self proclaimed cookie connoisseur, well I have eaten my fair share of cookies over the years so I gave myself that title. I know I’m not alone in saying that Oreo Cookies are some of my favorites so to me it made perfect sense to take some of my favorite store-bought cookies and not only make them from scratch, but make them GIANT!

A Birthday Cake Oreo is exactly how you would imagine it! It’s a party of vanilla and sprinkles in your mouth. Even though I was only introduced to Birthday Cake Oreo Cookies recently I have made up for lost time by enjoying many of them since. Just imagine the best vanilla cookie you ever had x 2 + sprinkles = deliciousness. That is math that I can get on board with.

The dough freezes perfectly so they can be baked off later. Double up and have reserves to “Bake in case of emergency.”

The cookie dough is such a small amount you can mix it by hand without the need for a mixer.

In addition to my Birthday Cake OREO, you can find recipes for my Original Chocolate & Red Velvet OREO Cookies!

  1. Preheat oven to 350 degrees.
  2. Pour oats into a food processor or high-powered blender and pulse until partially ground, about 15 seconds. In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg and ground oats until completely incorporated.
  3. In a separate large bowl, cream together butter, sugar and brown sugar until light and fluffy (about 3 minutes). Add in eggs one at a time, mixing until combined after each addition. Stir in vanilla.
  4. Slowly add in dry ingredients to wet ingredients and mix just until combined.
  5. Scoop dough out onto baking sheet (I used a silpat liner) in heaping tablespoonfuls. Bake in preheated oven for 11 – 15 minutes. Allow cookies to rest on baking sheet several minutes before transferring to a wire rack to cool completely.
  6. For the icing, whisk together powdered sugar and milk in a mixing bowl and dip tops of cooled cookies in icing and allow excess to run off or alternately spread icing over cookies. Return to wire rack and allow icing to set. Store in an airtight container at room temperature.

Chewy Confetti Cookies

These Chewy Confetti Cookies taste just like Birthday Cake! This cake mix box recipe makes fudgy cookies with baked in white chocolate chips and extra sprinkles! Enjoy these sprinkle cookies that every family loves!

Pillsbury Funfetti cake mix, but Betty Crocker has a pretty decent &ldquosuper moist party rainbow chip&rdquo cake mix that works good too. If you&rsquore looking for organic check out Annie&rsquos confetti cake mix.

These cookies are really easy to make because we&rsquore using boxed cake mix, so you don&rsquot have to do the work of measuring out flour, baking soda, baking powder, sugar, salt, etc. All you need to do is add a box of cake mix in a bowl with vegetable oil and eggs, give it a little mix (I like using a hand mixer). Once it&rsquos all mixed up add in white chocolate chips and sprinkles, stir with a spoon and then bake. So simple! So delicious! You&rsquore going to love these Confetti Cookies!

freezer bags. These will last up to 4 months. When ready to eat, remove from the freezer and throw in the microwave for a few seconds to warm up.

More Harry Potter Recipe Favorites

I haven’t made nearly enough Harry Potter recipes and I’m kind of embarrassed about it. It’s time to turn that around! About eight years ago my twin sister threw a Harry Potter party and we put together some really fun food ideas. Butterbeer Freeze and Butterbeer Krispy Treats are two butterbeer favorites that we make over and over, whether it’s Harry’s birthday or just a Friday night. I made a yummy Gryffindor Popcorn with all the colors of Gryffindor house.

Ingredients US Metric

  • For the birthday cake cookies
  • 2 sticks (8 oz) salted butter, at room temperature
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 1/2 cup rainbow sprinkles
  • For the frosting
  • 1 stick (4 oz) salted butter, softened
  • 3 cups confectioners’ sugar
  • 1 teaspoon almond extract
  • 1 to 3 tablespoons milk, preferably 2% or whole
  • To assemble the birthday cake cookies
  • 1/2 cup rainbow sprinkles


Preheat the oven to 350°F (180°C). Line 3 baking sheets with parchment paper.

Using a stand mixer fitted with the paddle attachment or a large bowl with a hand mixer on medium speed, combine the butter, granulated sugar, eggs, and vanilla and beat until creamy and free of lumps, about 2 minutes.

In a separate bowl, combine the flour, baking powder, and salt. Gradually add the flour mixture to the butter mixture, beating on medium speed until just combined, about 2 minutes. Stir in the rainbow sprinkles until just combined.

Scoop out tablespoon-size chunks of cookie dough and, using your hands, form them into balls. Place the balls 1 1/2 inches (4 cm) apart on the prepared baking sheets. Bake in the preheated oven for 9 to 11 minutes, or until golden brown around the bottom edges with no uncooked dough in the centers. Remove from the oven and cool on the sheets for about 5 minutes. Then slide the cookies onto a wire rack to finish cooling.

Using a stand mixer fitted with the whisk attachment or a large bowl with a hand mixer, combine the butter, confectioners’ sugar, and almond extract. Add the milk, 1 tablespoon (15 ml) at a time, until the desired consistency is achieved. Beat on medium speed for 3 minutes.

Spread the frosting on the cooled cookies and top with sprinkles. Originally published March 16, 2018.

Recipe Testers' Reviews

Christine F.

These delightful birthday cake cookies are basically happiness on a plate! They also live up to their name, tasting like the cookie equivalent of vanilla birthday cake. I was initially concerned that these cookies would be too sweet for my taste, but their small size and the generous amount of salt in the recipe work to counteract the sweetness.

I loved the addition of almond extract in the frosting, as it gives the cookies a more complex flavor than they would otherwise have. I also really enjoyed the cookies on their own (without frosting), although they definitely look much more festive with the frosting and sprinkles. Unsurprisingly, my kids adored them, and I'm sure they will be asking for them again before too long.

Sarah Heend

These cookies were good basic sugar cookies jazzed up with frosting and sprinkles. The cookies were soft and lightly flavored with vanilla. The frosting was nicely flavored with almond and was gorgeously white and fluffy. I topped half the cookies with sprinkles and left half just plain frosting. I slightly preferred the plain frosted ones, but only because the sprinkle-topped cookies were slightly on the sweet side.

I confess I don’t often have sprinkles on hand, but after making these cookies, I might just keep some around to liven up future desserts. The cookies came together quickly and looked just gorgeous on a plate. I had a hard time not eating way too many of the cookies, so I froze most of the batch. This worked only marginally well to keep me from eating them—they thawed quickly and I didn’t notice any loss of quality after freezing.

Sarah Kenney

These are a keeper! Starting time to eating time was an hour, which makes a strong argument for keeping this recipe, as when you have a craving you don't want to wait for molten hot brownies to cool. I loved the flavor—the almond extract makes them just different enough from a traditional sugar cookie and somehow cuts the super sweetness of the cookie and frosting combo.

While my assortment of leftover Christmas sprinkles didn't make for the most Insta-worthy shot, don't skip the sprinkles, they really do make the cookies special. Beware, they do spread when baking, so give them a lot of room on your baking sheet. I was going to take these cookies to a meeting later in the week, but they might not last the night!

Amy Wilschut

We happened to be heading to a cabin getaway with family to celebrate birthdays for a 3-year-old and an 11-year-old. I thought these would be a perfect treat to pack for the weekend. The cookies without the frosting are completely tasty on their own, easy to prepare, and it was easy to please a bunch of kids with these colorful cookies.

The frosting was quite good, but I might use unsalted butter next time I make these cookies it was a bit more salty and sweet than needed for a cookie that was already perfectly salty and sweet. The frosting was mainly a vehicle for more sprinkles and the kids had fun frosting their own.

Easy to Make Unicorn Cookies

If you haven’t tried any of our cake mix cookies recipes before, we’ve made quite a few. My current favorites include this chocolate cake mix cookie recipe and our lemon cake mix cookies.

But these new Unicorn Cookies might just take the top spot as our favorites! I think they’re just as much fun to eat as they are to make!

Whether you decide to call them Unicorn Cookies or go with the fun version of the name and make Unicorn Poop Cookies, these are fun to make no matter what you’re celebrating!

Unicorn Sugar Cookies Ingredients

  • 1 box of white cake mix, any brand
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 2 Tbsp. flour
  • 4-5 different colored sugars
  • Hershey’s Birthday Kisses

For these cookies, we used orange, yellow, pink, blue and purple colored sugars. You can customize your unicorn kiss cookies with any colors that you like. Generally, we try to give them a rainbow vibe that seems to best fit the “unicorn” theme.

Also, if you’re having trouble finding the Hershey’s Birthday Kisses, you can use any white chocolate Kisses. The Cookies ‘n’ Creme Kisses work great too!

We have seen the Birthday Kisses at most of our local stores around here including the grocery stores, Target and Walmart! Or you can always order a bunch on Amazon!

Unicorn Cookies Recipe

This recipe is easy to make. If you’ve made cake mix cookies before then you know the basics. We just jazz the basic recipe up a bit with the colored sugar to turn it into the unicorn poop cookies recipe!

Cookies and Cream Cake

Cookies and cream is so much more than a nostalgic ice cream flavor it’s also the key to this striking triple-layer cake. Cookie “crunchies” sprinkled between the layers and "crunchie crumbs" stirred into the frosting add delightful texture to every bite. For those that love the classic ice cream, this is the ideal celebration cake.


  • 1/4 cup (22g) black cocoa
  • 1/2 cup (99g) granulated sugar
  • 3/4 cup (90g) King Arthur Unbleached All-Purpose Flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon espresso powder, optional
  • 5 tablespoons (71g) butter, melted

*See "tips," below for a shortcut version using storebought cookies

  • 2 1/4 cups (270g) King Arthur Unbleached All-Purpose Flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1/4 cup (21g) black cocoa
  • 1/2 cup (42g) Dutch-process cocoa
  • 1 3/4 cups (354g) granulated sugar
  • 8 tablespoons (113g) unsalted butter, at room temperature
  • 1/3 cup (64g) vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup (227g) milk
  • 1/2 cup (113g) brewed coffee, cooled or water
  • 4 large eggs
  • 2 1/4 cups (383g) white baking chips or morsels*
  • 1 cup (227g) heavy or whipping cream
  • 1/4 teaspoon salt
  • 2 teaspoons vanilla extract
  • 6 tablespoons (85g) butter, at room temperature
  • 6 tablespoons (70g) vegetable shortening
  • 1/4 cup (28g) confectioners’ sugar

*Be sure to use white baking chips or morsels, not true white chocolate see “tips,” below.


Preheat the oven to 350°F. Lightly grease a baking sheet, or line it with parchment.

To make the cookie crunchies: In a medium bowl, sift together the cocoa, sugar, flour, baking powder, salt, and espresso powder. Stir to combine.

Add the melted butter and mix until pea- to walnut-sized crumbs form.

Transfer the crumbs to the prepared baking sheet and bake for 20 minutes, or until you begin to smell chocolate and the crumbs feel dry to the touch. Halfway through the bake time, give the crumbs a stir to break up any large pieces.

How to assemble and frost a layer cake

Remove the crunchies from the oven and set them aside to cool completely.

Leave the oven on (350°F). Lightly grease three 8” round cake pans.

To make the batter: In a large mixing bowl, or the bowl of your stand mixer, sift together the flour, baking powder, baking soda, salt, cocoas, and sugar.

Add the butter and mix at low speed for 1 minute. With the mixer running, add the oil and continue mixing until the mixture looks sandy, about 30 seconds more.

In a large measuring cup, combine the vanilla with the milk and coffee (or water), and add all at once to the dry ingredients. Mix for 1 minute at low speed. Stop and scrape the sides and bottom of the bowl, then mix for 30 seconds more.

Add the eggs one at a time, beating well at medium-high speed between additions.

Scrape the sides and bottom of the bowl and mix for 30 seconds more. The batter will be thin.

Divide the batter among the prepared pans, using about 2 cups (460g) batter per layer. Smooth the tops of the layers with an offset spatula.

To bake the cakes: Bake the cakes for 24 to 26 minutes, until the top of one springs back when very lightly touched in the center, and the edges just begin to pull away from the sides of the pan. A toothpick or paring knife inserted in the center will come out clean.

Remove the cakes from the oven and cool completely in the pans.

To make the frosting: Place the baking morsels in a large bowl or in the bowl of a stand mixer.

Heat the cream in a saucepan set over medium heat (or in the microwave) until the mixture begins to steam. Pour the cream over the baking morsels and let sit for 2 to 3 minutes. Gently stir until the morsels are completely melted. Set the mixture (ganache) aside to cool to room temperature (75° or below).

Once the ganache has cooled to room temperature, stir in the salt and vanilla.

Using an electric hand mixer or a stand mixer with the whisk attachment, whip the ganache on low speed, slowly adding the butter and shortening in several additions.

After the butter and shortening have been added, increase the speed to high and whip the ganache until fluffy, stopping to scrape down the sides of the bowl as needed.

Sift the confectioners' sugar into the whipped ganache and mix to combine.

To assemble the cake: Set aside 1 cup (about 110g) of cookie crunchies. Pulse the remaining cookie crunchies in a food processor or put them in a plastic bag and use a rolling pin to grind into fine crumbs you should have about 1 cup (151g) of fine crumbs.

Fold 2/3 cup (100g) fine crumbs into the prepared frosting, setting aside the remainder to decorate the frosted cake.

Place one of the cake layers on a serving plate or cake stand tuck strips of waxed or parchment paper underneath the edge of the cake to keep the plate clean.

Spread the cake with about 3/4 cup (140g) of frosting, then sprinkle about 1/2 cup (55g) cookie crunchies over the frosting. Center the second layer atop the first and press gently to set it in place.

Spread the second layer with about 3/4 cup of frosting, then sprinkle the remaining cookie crunchies over the frosting. Place the third layer on top and press gently to set it in place.

To finish the cake: For the best-looking cake, apply the frosting in two steps. First, spread a very thin layer of frosting around the sides and across the top this is called a crumb coat. It should be thin enough to see through in places. Refrigerate the cake for 20 minutes to let this layer set. (You can skip this step if time is a factor.)

Once the cake is chilled, use the remaining frosting to coat it thoroughly and evenly. Sprinkle the frosting with the remaining fine cookie crumbs. If you have any leftover frosting, use it to pipe decorations on the top and/or around the base, as desired.

Cover the cake and store it at room temperature, or in the refrigerator if your kitchen is hot. Let it come to room temperature before serving.

Store leftovers, covered, at cool room temperature for a couple of days freeze for longer storage.

Tips from our Bakers

While any three-layer chocolate cake recipe could potentially work for the cake part of this creation, we recommend the one featured here: its combination of black and Dutch-process cocoas really helps brings the chocolate flavor front and center.

You’d usually want to bake with a top-quality real white chocolate — but not this time. We find that the flavor of true white chocolate here is too strong white baking morsels or chips yield the perfect nostalgic cookies and cream flavor. When purchasing chips/morsels, look for a product that doesn’t include the word “chocolate.”

Skip the homemade cookie crunchies if you're short on time. Instead, use storebought chocolate sandwich cookies. Use a food processor to grind about 10 sandwich cookies (cream filling and all!) until it resembles coarse sand you should have about 1 cup (110g) of crumbs. Fold about 2/3 cup of the crumbs into the frosting, reserving the rest for decoration.

For the cookie crunchies between the layers, roughly chop another 10 sandwich cookies. Sprinkle about 1/2 cup of the chopped cookies evenly over the first frosted layer, and use the remaining chopped cookies to sprinkle over the second frosted layer. Decorate the cake as desired, topping with additional sandwich cookies as a garnish.
