Here is the recipe for my cookie dough cake as asked for:
USE only fresh eggs please. Since there is raw egg in the recipe it is important to use fresh eggs and to only store and eat the cake for 48 hours. Store the cake in the fridge covered in plastic wrap.
TIP: if you put a few toothpicks in the top of the cake, it will keep the plastic wrap from sticking to the ganache.
Preheat oven 350
2 cups all-purpose flour
2 teaspoons baking powder
3/4 teaspoon kosher salt
2 sticks lightly salted butter, room temperature, plus additional for greasing the pans
2 cups granulated sugar
Cookie dough filling:
2 1/4 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 cup (2 sticks) butter, softened
3/4 cup granulated sugar
3/4 cup packed brown sugar
1 teaspoon vanilla extract
2 large eggs
2 cups (12-oz. pkg.) Semi-Sweet Chocolate Morsels
8 ounces chocolate chips
1/3 cup whipping cream
In a large bowl, combine the flour, baking powder, and salt. Stir to blend. In the bowl of an electric mixer fitted with the whisk attachment, beat the butter until smooth and add the sugar. Continue whipping until the mixture becomes fluffy, 2 to 3 minutes. Note: this process can be done with a whisk by hand. Add the eggs, 1 at a time, taking care that each egg is thoroughly integrated. Add the flour mixture and combine.
Grease the 2 pans with butter and fill each with half of the batter. Place the pans in the center of the oven. Bake until the center is firm or when the tip of a small knife emerges clean when it pierces the center of each cake, 30 to 40 minutes. Remove from the oven and allow to cool thoroughly, 1 hour at least. Once completely cool, using a serrated knife, slice each cake in half horizontally to form 4 equal layers. Place the layers on a flat surface. Set aside.
For cookie dough filling: Combine flour, baking soda and salt in small bowl. Beat butter, granulated sugar, brown sugar and vanilla extract in large mixer bowl until creamy. Add eggs, one at a time, beating well after each addition. Gradually beat in flour mixture. Stir in morsels
spread cookie dough on each layer of cake as you build it into one cake. Melt ganache together, then pour on top of the cake.
Here is a picture of it submitted by a reader. She did it in 2 layers which is just fine too.
