Step‑by‑Step Instructions for Cookies and Cream Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease three 8-inch round cake pans with butter or oil and line the bottoms with parchment paper. This ensures that the Cookies and Cream Cake layers will effortlessly release from the pans after baking, making the process smoother.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 tablespoon of baking powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. This blend provides structure to your cake. Set the bowl aside while you gather the wet ingredients, which will complement these dry components beautifully.
Step 3: Cream Fat and Sugar
In another bowl, beat ½ cup of vegetable oil and 1 cup of granulated sugar together until the mixture is creamy and well combined. This should take about 2-3 minutes. Gradually add in ½ cup of sour cream, mixing until smooth. The creamy texture will add moisture to your Cookies and Cream Cake.
Step 4: Combine Wet and Dry Ingredients
Gradually add the flour mixture to the wet ingredients, alternating with 1 cup of milk. Start and finish with the flour mixture. Mix until just combined, taking care not to overmix. This is crucial for a fluffy cake texture. Gently fold in 3 whipped egg whites and 1 cup of chopped Oreos into the batter for that delightful crunch.
Step 5: Bake the Cake Layers
Divide the batter evenly among the prepared cake pans. Bake in the preheated oven for about 30-35 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown and spring back when lightly pressed. Allow the layers to cool in the pans for 10 minutes before transferring them to a wire rack.
Step 6: Make the White Chocolate Mousse
For the mousse, melt 8 ounces of white chocolate in a heatproof bowl over a pot of simmering water or in the microwave. Combine it with 1 cup of heavy cream while it's still warm. Once smooth, add in 8 ounces of cream cheese, mixing until well incorporated. Fold in 1 cup of whipped cream and ½ cup of chopped Oreos for an extra layer of goodness.
Step 7: Prepare the Frosting
In a large mixing bowl, beat ½ cup of butter and 8 ounces of cream cheese together until creamy. Gradually add in 2 cups of powdered sugar and 1 cup of pulverized Oreos, mixing until fluffy and smooth. This Cookies and Cream Cake frosting will provide a rich and delightful layer that complements the cake perfectly.
Step 8: Assemble the Cake
Place one layer of the cooled cake on a cake stand. Spread a generous layer of white chocolate mousse over it, followed by a layer of frosting. Repeat the process with the remaining cake layers, finishing with a smooth layer of frosting on top. Make sure to spread the frosting evenly to create a beautiful finish.
Step 9: Add Ganache Drip
To prepare the ganache, heat ½ cup of heavy cream until it just begins to simmer. Pour it over 6 ounces of semi-sweet chocolate and let it sit for a few minutes before stirring until smooth and glossy. Allow the ganache to cool slightly before drizzling it over the top of the assembled Cookies and Cream Cake for a stunning drip effect.
Step 10: Chill and Decorate
Chill the assembled cake in the refrigerator for at least 30 minutes to set the mousse and ganache. Once chilled, decorate the top with halved Oreos and additional cookie crumbs if desired. This final touch will enhance the cake's appearance, making your Cookies and Cream Cake a showstopper at any gathering.
