Oreo cookie cake is a giant cookie stuffed with Oreos and decorated with vanilla buttercream frosting. This fun dessert comes together in 40 minutes and is everything you love about a cookie in cake form!
Cookie cakes were the second most popular cake I made working in bakeries. They are the best because they require zero chill time or scooping. Instead, the cookie dough is baked in a cake pan, so it turns out super thick with the classic gooey and chewy texture of a regular cookie.
When you don’t have time to make my Oreo cupcakes or Oreo chocolate chip cookies, this Oreo cookie cake is the next best thing. Make it to serve a crowd and decorate it for a birthday party, holiday, or other special occasion!
If you prefer a brownie version, try my Oreo brookies instead!

Pro Tips for a Perfect Cookie Cake
Use a kitchen scale. Baking with a scale is my #1 baking tip! Using too much flour can result in a dry and crumbly texture.
Line the pan. This is especially important if you are using a regular cake pan and not a springform pan. The dough will stick to the pan and be very difficult to remove if not lined.
Use room temperature ingredients. Like any regular cookie recipe, it’s important to use room-temperature eggs for a smooth cookie dough that bakes evenly.
Maintain an even thickness. Spread the cookie dough evenly in the cake pans to ensure even baking. You can use an offset spatula or the back of a spoon to achieve a smooth surface.
Customize your frosting. Consider adding finely crushed Oreos to your frosting for even more Oreo flavor. You can also serve it warmed up with scoops of vanilla or Oreo ice cream!
Use a sharp knife for slicing. For clean slices, use a sharp knife and wipe it clean with a warm cloth in between cuts!
Ingredient Notes and Substitutions
Brown sugar: Like in my Oreo cheesecake cookies, the molasses in brown sugar gives the cake a chewy cookie texture.
Butter: If you want to take your cake over the top, use cultured butter like Kerrygold! This kind of butter is fermented, so it has a richer, tangier flavor compared to traditional butter. After using it in so many bakeries, it’s my #1 recommendation for any cookie recipe for a bakery-style flavor!
Oreo cookies: Roughly chop the cookies before adding them to the cookie dough. You can substitute any special flavor like golden Oreos, java chip, or Halloween orange. I’ve also had readers add chopped Heath bars and chocolate chips!
Eggs: Note that you will need two whole eggs plus an extra egg yolk. The extra yolk is what makes the cookie cake really rich and gooey!

Recipe Instructions
Step 1: Line the baking pan. Line the bottom of a buttered 9-inch cake pan with two long strips of parchment paper in an X shape. Then, place a round of parchment on the bottom of the pan.
Step 2: Combine the wet ingredients. In a stand mixing bowl, cream the butter and sugars until light and fluffy, then mix in the eggs, egg yolk, and vanilla extract.
Step 3: Fold in the dry ingredients. Mix in the all-purpose flour, baking soda, and salt until almost combined and some flour pockets remain. Then, fold in the Oreo cookies.
Step 4: Press the cookie dough into the pan. Use an offset spatula to spread the cookie dough evenly into the pan. Press more Oreo crumbs and pieces on top if desired.
Then bake the cake! Once baked, let it cool completely on a wire rack before frosting.
Step 5: Make the vanilla frosting. Cream the butter and powdered sugar together, then mix in the heavy cream and vanilla extract. Beat until super light and fluffy!
If you don’t care for vanilla, try cream cheese frosting or chocolate fudge frosting, or enjoy without!
Step 6: Decorate the top of the cake. Pipe dollops of buttercream around the border of the cake and garnish with sprinkles or more chopped Oreo pieces.
You can also double the frosting and decorate the whole cake!
Storage, Freezing, and Make Ahead
Storage: This Oreo cake is best stored in an airtight container at room temperature for 3-4 days. It can be stored both with or without the frosting!
Freezing: Store the cut slices or whole cake in an airtight container for up to one month. You can freeze it with or without the frosting on top.
Make ahead: I don’t recommend making the cookie dough ahead of time as it’s best baked right after mixing. However, this cake is just as delicious on the second day as the first, so baking it the day before is perfect for prepping!
FAQs
You could use an 8-inch springform pan for this recipe. It will take longer to bake because it will be thicker.
A springform pan is the easiest to remove once baked, but if you don’t have one, a regular cake pan works perfectly! See the above process photo (step #1) to see how I line mine for easy removal.
The best way to test is to insert a toothpick or skewer into the center. If it comes out clean or slightly moist, it’s ready!
Nope! This recipe was designed to be baked right away so you can skip the chill time 🙂
I used a French star tip, Azteco #869.

Turned out GREAT!!!! Big chunks of Oreos and yummy, chewy cookie…perfect combo!
Came out perfectly! I personally cut 1/4c of brown sugar out. I’d love to add a chopped bar or Hersheys cookies and cream and bake in a cast iron skillet next time.
10/10 recipe, this was so delicious
My husband & I loved this recipe! I did 1 cup Oreos and 1 cup chocolate chips and it was phenomenal!
