COOKIES AND CREAM MOUSSE CAKE

Cookies and Cream Mousse Cake is what happens when I cannot decide between a chocolate dessert and an Oreo dessert, so I combine both into one pan. Layers of fudgy chocolate cake, silky chocolate mousse, whipped cream, and crushed Oreos stack up into something that genuinely feels like too much in the best possible way.

What Is Cookies And Cream Mousse Cake?

Cookies and Cream Mousse Cake is a layered dessert built in a baking pan rather than stacked as a traditional round cake. It combines a chocolate cake base with a light chocolate mousse layer, whipped cream, and a generous topping of crushed Oreo cookies. It is scooped and served rather than sliced neatly, which makes it perfect for casual gatherings.

What You Will Need For Cookies And Cream Mousse Cake

Here is what goes into building each layer of this Cookies and Cream Mousse Cake.

• Chocolate cake (1 baked 9×13 pan, cooled): the sturdy base layer for your mousse cake. Boxed or homemade both work well here.
• Heavy whipping cream (2 cups, divided): used both for the mousse and the whipped topping layer.
• Semi-sweet chocolate (8 ounces, melted): the base of the rich chocolate mousse layer.
• Powdered sugar (1/2 cup, divided): sweetens both the mousse and the whipped topping without adding grit.
• Cream cheese (8 ounces, softened): adds tang and helps the mousse layer hold its shape once chilled.
• Vanilla extract (1 teaspoon): rounds out the flavor in the mousse layer.
• Crushed Oreo cookies (1 1/2 cups, divided): folded into part of the layers and sprinkled generously on top for that classic cookies and cream crunch.

Step By Step Instructions For Cookies And Cream Mousse Cake

Step 1: Prepare the base. Bake your chocolate cake in a 9×13 pan and let it cool completely before building the layers on top.

Step 2: Make the mousse. Beat the softened cream cheese with half the powdered sugar and vanilla until smooth, then fold in the melted chocolate until fully combined.

Step 3: Whip and fold. Whip 1 cup of the heavy cream to stiff peaks, then gently fold it into the chocolate cream cheese mixture to create a light, airy mousse.

Step 4: Spread the mousse layer. Spread the chocolate mousse evenly over the cooled cake, smoothing it out with an offset spatula.

Step 5: Whip the topping. Beat the remaining heavy cream with the remaining powdered sugar until stiff peaks form, then spread it evenly over the mousse layer.

Step 6: Add the Oreos. Fold half the crushed Oreo cookies into the whipped topping before spreading, or layer them separately for extra crunch, then sprinkle the remaining crushed Oreos generously over the top.

Step 7: Chill completely. Refrigerate your Cookies and Cream Mousse Cake for at least three hours, or overnight, so every layer sets properly before serving.

Serving Suggestions

Scoop generous squares of Cookies and Cream Mousse Cake with a large spoon so you capture every single layer in one bite. It pairs wonderfully with a cold glass of milk, and it makes an excellent make ahead option for birthday parties or summer barbecues where you want something cool and creamy.

Tips For The Perfect Cookies And Cream Mousse Cake

• Cool the cake fully: spreading mousse on a warm cake will melt it and ruin the clean layers.
• Chill your bowl and beaters: cold tools whip cream faster and give you stiffer, more stable peaks.
• Do not skip the overnight chill: longer chilling gives the mousse layer time to firm up for cleaner scoops.
• Add Oreos last: sprinkling the crushed cookies right before serving keeps them crunchy instead of soggy.

Q&A Section

Can I make this cake a day ahead? Yes, this Cookies and Cream Mousse Cake is actually better made a day ahead so the layers have plenty of time to set.

Can I use a store bought whipped topping? Yes, a tub of thawed whipped topping works as a shortcut instead of whipping cream yourself.

How long does it keep in the fridge? Covered tightly, it stays fresh for about four days, though the Oreo topping softens slightly over time.

Can I freeze this dessert? Yes, you can freeze it without the Oreo topping for up to one month. Add fresh crushed cookies after thawing.

Behind The Scenes Of This Recipe

The first version of this Cookies and Cream Mousse Cake I made had way too thin a mousse layer, since I skipped chilling my bowl before whipping the cream. It never firmed up properly. Once I chilled everything ahead of time, the mousse held its shape perfectly and sliced beautifully. For more layered dessert ideas like this one, follow my Pinterest page.
