Oreo Layer Cake with Marshmallow Cream Filling

I have a seriously impressive yet easy cake for you today.  I don't normally use cake mixes, but my life has been seriously crazy lately and I needed a break!  I've been wanting to make an Oreo cake, and this is what I came up with.  I threw some black cocoa powder in with the cake mix to give me a seriously dark Oreo-like chocolate flavor in these moist cake layers.  The marshmallow cream filling is light and fluffy and delicious.  Can't even get over the filling.  The frosting is full of chopped Oreos, which give you some nice chunks of Oreo in each bite.

Oreo Layer Cake with Marshmallow Cream Filling

Chocolate Cake:
1 box dark chocolate cake mix
1 box (4 serving size) instant chocolate pudding mix
1/4 cup black cocoa or dark cocoa powder
2 eggs
1 3/4 cups milk

Marshmallow Cream Filling:
1 container (7 ounces) marshmallow cream
1/2 cup shortening
1/3 cup powdered sugar
pinch of salt
1 teaspoon clear vanilla extract
2 teaspoons hot water

Oreo Frosting:
1/2 cup butter, room temperature
1/2 cup coconut oil
1 teaspoon vanilla extract
1/2 teaspoon butter flavoring
4 cups powdered sugar
2 Tablespoons milk
18 Oreos, chopped
Extra Oreos for garnish

Preheat the oven to 350F.  Grease 2 9-inch round baking pans and line the bottoms with parchment paper, then lightly grease the paper.  Set aside.

In a large bowl, whisk together the cake mix, pudding mix, and cocoa powder.  Whisk in the eggs and milk until combined and well blended.  Pour the cake batter evenly in the prepared pans and smooth the tops.  Bake in the preheated oven for about 20 minutes, or until a toothpick inserted in the center comes out clean.  Remove cakes from the oven and let cool for about 10 minutes.  Carefully turn the cakes out onto a cooling rack to cool completely.

For the marshmallow cream filling, in a medium bowl, place the marshmallow cream, shortening, powdered sugar, salt, vanilla, and hot water.  Beat together until completely combined, smooth and fluffy.

For the Oreo frosting, cream together the butter, coconut oil, vanilla, and butter flavoring.  Beat in the powdered sugar, one cup at a time, until combined.  Add the milk (adding more if necessary to reach the desired consistency), and beat the frosting until smooth.  On low speed, beat in the chopped oreos until evenly distributed.

To assemble the cake, place one cooled cake layer on a serving plate.  Spread the cream filling on top, then place the second cake layer on top of the cream filling, pressing down slightly.  Frost the top and sides of the cake with the Oreo frosting.  Garnish with extra Oreos, if desired. Makes 16 servings.
