Step 1

Chocolate cake:

Melt both chocolates together with the 6 tablespoons of water. Use either a double-boiler or a microwave. Stir until smooth; set aside to cool to room temperature.
Place butter and 1 ¼ cup of the sugar in a bowl and beat until light and fluffy, about 5 minutes. Beat in the melted chocolate, then the egg yolks, one at a time.

Step 2

Sift together the flour, baking powder, baking soda, and salt. Mix in half of the dry ingredients into the creamed butter mixture, then the buttermilk and the vanilla extract, then the rest of the dry ingredients

Step 3

In a separate metal or glass bowl, beat the egg whites until they hold soft, droopy peaks. Beat in the ¼ cup of sugar until stiff.

Step 4

Fold about one-third of the egg whites into the cake batter and then fold in the remaining egg whites just until there’s no trace of egg white visible.

Step 5

Divide the batter into the 2 prepared cake pans, smooth the tops, and bake for about 25-30 minutes, until a toothpick inserted into the center comes out clean.
Cool cake layers completely.

Step 6

Oreo Buttercream Frosting:

Place eggs and sugar in stand mixer bowl attach thermometer to bowl and then place bowl over simmering water. Whisk mixture constantly until it comes to 150 degrees F. Remove bowl from heat and place back with stand mixer. Beat mixture on medium until it becomes glossy and shiny and stiff peaks begin to form, about 8-10 minutes.

Step 7

Add butter in a few pieces at a time and beat to combine after each addition. Mixture may look curdled half way through, but continue adding the butter and beating and the mixture will become smooth once more.
Add in vanilla and crushed Oreos, beat to combine

Step 8

Chocolate Pouring Sauce:

Place chocolate and heavy cream in a bowl over simmering water. Let chocolate and cream sit for 2-3 minutes to melt without stirring. Then slowly stir mixture to combine. Add powdered sugar and mix to combine. Add water 1 tablespoon at a time, mixing after each addition until pouring consistency is reached. Set aside and let sauce cool to warm.

Step 9

1. Slice each mini cake into three layers. Frost the top of each layer with frosting and then cover whole mini cake with frosting. Freeze mini Oreo cakes for an hour, so the frosting does not melt when it comes into contact with the warm chocolate sauce. Remove mini Oreo cakes from freezer and pour chocolate sauce on top. Pipe a small dollop of frosting on top and then place mini Oreo in center.
