(1) 8 ounce package of cream cheese, cut into cubes
4 ounces unsalted butter, cut into cubes
3 1/2 cups powdered sugar
1/2 teaspoon salt
20 oreo cookies, roughly chopped + 4 crushed Oreos finely crushed for topping the cake
3 -4 tablespoons heavy cream (milk may also work, but I’m not 100% on that)
For the Cake
Preheat oven to 350 degrees (F). Line 3 round 9 ” pans with parchment paper and grease well. Arrange 7 oreo cookies on the bottom of each pan; set pans aside.
In a mixing bowl whisk together the flour, baking powder, baking soda, salt, and cocoa powder; Set aside.
Pour the boiling water into a large bowl. Add butter, espresso, and chocolate chips, and whisk until butter and chocolate are completely dissolved. Whisk in sugar and stir until dissolved. Add milk, eggs, and vegetable oil and beat until the mixture is completely combined, about 1 minute. Pour the dry ingredients into the wet mixture, and stir until just combined.
Divide the batter evenly among the three pans; about 2 1/4 cups of batter in each. Bake cakes for 22 – 24 minutes, or until a cake tester comes out clean. Run a knife around the edge of the cakes before carefully turning them out of the pans and transferring them to a cooling wrack to cool completely.
Once cakes are cooled, you can ice and decorate them! Use a serrated knife to cut the rounded top off ONE of the layers.
For the icing
Place cream cheese and butter in the body of a stand mixer fitted with the whisk attachment and beat for 1 -2 minutes, or until the mixture is light and fluffy. Add powdered sugar, a cup at a time. Add salt and oreo cookies and beat until the oreos are evenly distributed in the icing. Add cream as needed, adding one tablespoon at a time until it reaches your desired consistency; you don’t want your icing to thin!
Place the first layer of cake flat side up on a large plate or cake stand. Smooth about 3/4 cup of the icing over the top of the layer, allowing it to drip down the sides as well. Place the next layer (the layer you cut the rounded top off of) on top. Repeat icing the same as the first layer. Top this layer with the last tier of cake, and continue to ice the top, then go around the sides, frosting the cake evenly. You will have extra icing leftover for touchups if needed. Top the cake with crushed oreos, and enjoy!
