Step 1

Butter and flour three six inch pans. I use cake strips on my pans for more even baking as well. Preheat oven to 340F

Step 2

In a standing mixture fitted with a paddle attachment, beat butter until light and fluffy.

Step 3

Sift the dry ingredients together in a large bowl.

Step 4

Beat the dry ingredients into the butter until well incorporated, scrape the bowl at least once.

Step 5

Beat the wet ingredients together in a medium bowl.

Step 6

Add the wet to the butter mixture and mix until just combined. Fold in the crushed Oreos at the very end and mix until just combined.

Step 7

Divide the mixture evenly into the cake pans

Step 8

Bake at 340 for about 25-30 minutes or until the centers are springy to the touch.

Step 9

Beat the butter until light and fluffy. Add the confectioners' sugar and cream and mix.

Step 10

Reserve about a cup of the buttercream for the white dollops. Which will be piped with an 869 tip.

Step 11

Mix in the crushed Oreos into the large batch of buttercream.

Step 12

Melt chocolate and cream together on low heat. Whisk together and set aside. You might need to add more or less cream to achieve the desired consistency.

Step 13

Oreo buttercream goes between each layer as well as a swirl of chocolate. Don't go overboard with the ganache as it will overpower the other flavors.

Step 14

Coat outside with buttercream and smooth.

Step 15

Add a skirt of crushed Oreos at the bottom of the cake.

Step 16

Pour the ganache on top and allow to drip. Smooth top with an offset spatula.

Step 17

Pipe white buttercream dollops on top with an 869 tip
