Full Ingredients List – You only need 3 things!

28 Oreo Cookies—Use original Oreos, not Double-Stuffed, to get the right balance of cookie and cream. These will be crushed into a fine powder to create the base of the cake batter.
1 Cup Whole Milk – This helps turn the crushed Oreos into a smooth batter and keeps the cake soft and moist. Whole milk works best for a rich texture, but you can try other milk options if needed.
1 Teaspoon Baking Powder – This acts as a leavening agent, helping the cake rise and become light and fluffy instead of dense. Be sure to mix it well with the crushed Oreos for even baking.

How to Make Oreo Cookie Cake

Prepare the Baking Dish – Grease an 8-inch microwave-safe baking dish (square or round) with non-stick cooking spray. Cut a piece of parchment paper to fit the bottom of the dish, place it inside, and spray it again with non-stick cooking spray.
Crush the Oreos – Place the Oreo cookies in a food processor and blend until they become a fine powder. If you don’t have a food processor, you can crush them in a sealed plastic bag using a rolling pin.
Make the Batter – In a medium mixing bowl, combine the crushed Oreos and baking powder. Pour in the milk and mix until smooth and well combined.

Microwave the Cake – Pour the batter into the prepared baking dish. Microwave on high for 6 minutes, or until a toothpick inserted in the center comes out clean.
Cool & Serve – Carefully remove the cake from the microwave and turn it out onto a serving plate or cooling rack. Let it cool to room temperature before slicing. Add frosting or toppings if you like, then enjoy!

Best Frostings for Your Oreo Cookie Cake

Adding frosting takes your Oreo cake recipe to the next level! Whichever frosting you choose, be sure to allow the cake to cool completely before you spread it on top. You can also frost the sides of the cake, then cover them with crushed Oreos for a pretty finished look. Have fun experimenting with different flavors and textures to find your favorite!

Premade Canned Frosting—For a super quick finish, top your cake with your favorite prepared frosting.
Oreo Buttercream Frosting – This frosting is packed with Oreo flavor and makes the perfect pairing for your cake. Using a paddle attachment on an electric mixer, beat butter, powdered sugar, and crushed Oreo cookies until light and fluffy. Add a little heavy cream for a smooth texture, then use a piping tip for a decorative touch.
Classic Vanilla Buttercream – If you love a simple and sweet option, this frosting is for you! In a medium bowl, beat butter and powdered sugar with a hand mixer on high speed until fluffy. Add a splash of vanilla and a bit of heavy cream to make it extra smooth.
Chocolate Ganache – For a rich, glossy finish, make a chocolate ganache by melting chocolate and heavy cream together until smooth. Let it cool slightly, then pour it over the top of the cake for a shiny, decadent layer.
Cream Cheese Frosting—If you love tangy, creamy frosting, beat together cream cheese, butter, and powdered sugar with a hand mixer or paddle attachment. This frosting pairs perfectly with the deep Oreo flavor of the cake.
Chocolate Glaze – A simple, thin layer of melted chocolate mixed with a little brown sugar makes a quick and easy topping. Drizzle it over the cake for a sweet, fudgy finish.
Whipped Cream or Cool Whip – For a light and airy topping, spread a layer of Cool Whip or homemade whipped cream over the cake.
Giant Cookie Cake – Make two cake layers with any white frosting between them to resemble a giant Oreo cookie. Use these Giant Sandwich Cake Pans for an Oreo-shaped cake.

Fun Mix-Ins for Your Oreo Cookie Cake

Want to take your Oreo cake recipe to the next level? Mix-ins are a great way to customize your cake and make it your own. Just stir them into the batter right before pouring it into the baking dish, then bake as usual. Try one or mix a few together for a unique and delicious treat!

White Chocolate Chips – These add a creamy sweetness that pairs perfectly with the rich Oreo flavor. Mix in about ¼ cup for little bursts of white chocolate in every bite.
Chopped Oreos – If you love extra crunch, add some chopped Oreos to the batter before baking. This gives the cake even more cookie goodness and texture!
Chocolate Chip Cookies—Crushed chocolate chip cookies can add a fun twist to this single-layer cake. They bring a buttery, chocolatey crunch that complements the soft cake.
