Doberge Cake (Dobash) - cooking recipe

Ingredients

1 (18.25 ounce) package white cake mix (such as Duncan Hines(R))
1 teaspoon baking powder
1 tablespoon all-purpose flour
1 tablespoon white sugar
1 1/3 cups water
2 tablespoons vegetable oil
3 egg whites
1 (3.9 ounce) package instant chocolate pudding mix
2 cups milk
1 (4 ounce) package cream cheese, softened
1/4 cup butter, softened
1 (16 ounce) box confectioners' sugar
1/2 cup unsweetened cocoa powder
1/2 teaspoon vanilla extract
1 tablespoon milk, or as needed

Preparation

Preheat oven to 350 degrees F (175 degrees C). Grease and flour 5 8-inch cake pans, and line them with parchment paper.
Whisk together the cake mix, baking powder, flour, and sugar in a large mixing bowl. With an electric mixer, beat the mixture with water, vegetable oil, and egg whites at low speed until thoroughly mixed; increase speed to medium, and beat 2 minutes. Scoop 1 cup of batter into each of the 5 prepared cake pans.
Bake in the preheated oven until cakes are set in the middle, about 8 minutes; watch carefully so the thin cakes don't burn. Cool in pans for 10 minutes, then remove to wire racks to finish cooling.
Whisk the chocolate pudding mix with 2 cups of milk in a bowl until thoroughly blended; let stand 2 minutes to thicken. Place a cake layer on a serving dish, and spread with about 1/2 cup of pudding; repeat with remaining layers and pudding, ending with a cake layer.
In a bowl, mash the cream cheese and butter together until thoroughly combined; mix in confectioners' sugar, cocoa powder, vanilla extract, and milk, slowly adding and mixing in milk as needed to make a spreadable frosting. Ice the top and sides of the cake with the frosting. Refrigerate leftovers.
