Ingredients
- 2 boxes triple chocolate cake mix
- Whole milk (as required by cake mix and filling)
- 3 cups unsalted butter, softened (divided)
- Large eggs (as per cake mix instructions)
- 1 cup brown sugar
- 2 teaspoons vanilla extract (divided)
- 1 teaspoon salt
- 1 cup all-purpose flour
- 5 cups powdered sugar (divided)
- 1 cup mini chocolate chips
- 1 package Oreo cookies (crushed and whole)
- Sky blue gel food coloring
- 1/2 cup semi-sweet chocolate chips
- 1/2 cup heavy cream (divided)
- 1 bag mini Chips Ahoy cookies
Instructions
- Preheat your oven to 350 degrees F and prepare three 9-inch round cake pans with baking spray and parchment paper.
- In a large bowl, combine the chocolate cake mixes, whole milk, softened butter, and eggs until smooth, then divide the batter between the pans and bake for 25-30 minutes until a tester comes out clean.
- For the filling, cream brown sugar and one cup of butter until fluffy, then mix in vanilla, salt, flour, and one cup of powdered sugar, folding in mini chocolate chips at the end.
- Prepare the frosting by beating two cups of butter with four cups of powdered sugar, vanilla, and heavy cream until silky, then tint with blue gel coloring and fold in crushed Oreos.
- Create the ganache by pouring heated heavy cream over chocolate chips, letting it sit for a minute, then whisking until glossy and cooling for ten minutes.
- Assemble by stacking the cake layers with the cookie dough filling in between, then frost the exterior with the blue buttercream.
- Finish the decoration by dripping ganache around the edges, pressing mini cookies into the base, and creating eyes using halved Oreos and chocolate chips.
Notes
To ensure your cookie dough filling is safe to eat raw, you can heat-treat the flour by microwaving it until it reaches 160 degrees F before mixing. If the blue frosting seems too soft, refrigerate it for fifteen minutes before piping the monster features to help them hold their shape. For the best drip effect, use a squeeze bottle to control the flow of the ganache around the edges of the chilled cake.
