No-Bake Cookies and Cream Mousse Cake

No-Bake Oreo Cookies and Cream Mousse Cake

Creamy, chocolatey, and wonderfully easy to assemble, this no-bake Oreo mousse cake turns three simple ingredients into a chilled dessert. Layers of crushed cookies and sweetened whipped cream soften together in the refrigerator, creating a cookies-and-cream treat without switching on the oven.

The mousse-style filling is light and fluffy, while the Oreo crumbs add rich cocoa flavor in every spoonful. It’s a simple make-ahead dessert for casual gatherings—or whenever you want something sweet with minimal effort.

Recipe at a Glance

• Prep time: 15 minutes
• Chill time: At least 4 hours
• Yield: About 6 servings
• Equipment: Electric mixer or whisk, mixing bowl, and a small loaf pan or serving dish

Ingredients

• 15 Oreo cookies
• 2 cups cold heavy cream
• 2 tablespoons sugar

Instructions

1. Crush the cookies.
   Place the Oreos in a sealed food-safe bag and crush them with a rolling pin, or pulse them briefly in a food processor. Leave a few small pieces for texture. There’s no need to remove the cream filling.

2. Whip the cream.
   Pour the cold heavy cream into a mixing bowl and add the sugar. Beat until medium-stiff peaks form: the cream should hold its shape when you lift the beaters. Stop before it becomes grainy.

3. Build the layers.
   Set aside a small handful of cookie crumbs for the topping. Sprinkle half of the remaining crumbs into a small loaf pan or serving dish. Spread half of the whipped cream over them, gently smoothing the surface. Repeat with the remaining crumbs and whipped cream.

4. Add the topping.
   Scatter the reserved Oreo crumbs over the final cream layer.

5. Chill until set.
   Cover and refrigerate for at least 4 hours, preferably overnight. This gives the cookies time to soften and the layers time to settle.

6. Serve cold.
   Spoon into bowls or cut into soft portions directly in the pan. Because this recipe contains no gelatin or other stabilizer, expect a delicate, creamy dessert rather than a firm, freestanding cake.

Tips for the Best Results

• Keep the cream cold. Cold heavy cream whips more easily. A chilled bowl can help, especially in a warm kitchen.
• Avoid packing down the crumbs. A loose cookie layer blends more naturally with the fluffy cream.
• Give it time. An overnight chill creates softer cookie layers and a more cohesive texture.
• Use individual glasses for easy serving. Alternate crumbs and whipped cream in small dessert cups for ready-to-serve portions.

Storage

Keep the dessert covered in the refrigerator and enjoy within 2–3 days. The cookies will continue to soften as it sits, so the texture becomes more tender over time.

A Simple Dessert Worth Making Ahead

With no baking and just three ingredients, this Oreo mousse cake is an easy way to satisfy a cookies-and-cream craving. Assemble it ahead of time, let the refrigerator do the work, and serve it chilled for a fluffy, creamy finish to any meal.
