Oreo Sheet Cake

OK, now you have some Oreos left from the other bars you need to make. Here is a great way to use them up. Oreo Sheet Cake. It has Oreo cookies in the cake and on the frosting. The frosting is so delicious – just like one big slice of chewy Oreo.


I don’t have much commentary to add this week. I am pretty tired and running on E. Hopefully this weekend I can recharge. I just got back from a long (and super fun) weekend in Fargo and apparently I am too old to act like a youngster anymore! Anywho, here is how to make them.


Chocolate sheet cake with Oreos and cream cheese frosting – so moist and delicious. Slightly adapted from Two Peas and Their Pod


For the Chocolate Sheet Cake:

2 cups granulated sugar
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
2 large eggs, lightly beaten
1/2 cup buttermilk or 1/2 cup milk with 2 tsp. white vinegar
1 teaspoon pure vanilla extract
1 cup unsalted butter
1/4 cup dark cocoa powder
1 cup hot water
1 cup chopped Oreo cookies

For the Cream Cheese Frosting:

1 (8 oz.) package cream cheese, at room temperature
1/2 cup butter
4 cups powdered sugar, sifted
1 teaspoon vanilla extract

Oreo cookies, chopped-for topping the cake


1. To make the sheet cake: Preheat oven to 350 degrees. Grease a sheet pan with cooking spray and set aside. I use a jelly roll pan.

2. In a large mixing bowl, whisk together sugar, flour, baking soda, and salt. In a separate bowl, whisk together eggs, buttermilk, and vanilla extract. Set aside.

3. In a small sauce pan, melt the butter on medium-low heat. Whisk in the cocoa powder and hot water. Turn up the heat to medium-high and bring the mixture to a boil. Add the melted butter mixture to the dry ingredients and mix until smooth. Stir in the egg mixture and mix until ingredients are combined. Stir in the chopped Oreo cookies.

4. Pour the batter into the prepared sheet pan and tap on the counter a few times to distribute the cake batter evenly. Bake the cake for 18 minutes, or until a toothpick comes out clean when inserted in the center.

5. While the cake is baking, make the cream cheese frosting. In the bowl of a stand mixer, beat the cream cheese, butter, sifted powdered sugar, and vanilla together. Beat with the beater blade until smooth and creamy.

6. When the cake is completely cool, frost the cake with the cream cheese frosting. Sprinkle the cake with chopped up Oreo cookies. Cut into squares and serve.


You will basically have three bowls to incorporate. The batter is very thin.


Before and after. Super dark chocolate from the dark cocoa.


Ohhh frosting. It makes me so happy.


Frost your bars and gently press the rest of the crushed up cookies into the frosting.


Slice and serve.


Enjoy! These are great for sharing.
