Ingredients

Oreo Crust:

36 Oreo cookies, whole (with filling), ground

1/2 cup unsalted butter, melted

Hot Chocolate Cheesecake Mousse Layer:

1/2 cup unsalted butter, softened

8 oz cream cheese, softened

1 cup powdered sugar

1 tsp vanilla extract

5 packets (0.73 oz each) instant hot cocoa mix (milk chocolate flavor)

1 1/2 cups heavy whipping cream

Chocolate Pudding Layer:

2 boxes (3.8 oz each) chocolate instant pudding mix

2 3/4 cups milk

1 cup mini marshmallows

Topping:

1 1/4 cups heavy whipping cream

2 tbsp powdered sugar

2 cups mini marshmallows

Optional: melted chocolate or Nutella drizzle

Instructions

1. Make the Oreo Crust:

Process Oreos into fine crumbs.

Stir in melted butter.

Press into a 13×9-inch casserole dish. Chill until firm.

2. Prepare Hot Chocolate Cheesecake Mousse:

In a bowl, beat softened butter, cream cheese, powdered sugar, and vanilla until smooth.

In a separate bowl, whip heavy cream with cocoa mix until stiff peaks form.

Fold chocolate whipped cream into the cream cheese mixture in two additions.

Spread over chilled crust. Chill again.

3. Add Chocolate Pudding Layer:

Whisk pudding mix with milk until thickened.

Stir in marshmallows and spread over mousse layer. Chill again.

4. Add Whipped Cream Layer:

Beat heavy cream and powdered sugar until stiff peaks form.

Spread over pudding layer. Refrigerate for several hours or overnight.

5. Garnish Before Serving:

Top with mini marshmallows and drizzle with melted chocolate or Nutella.

Slice and serve chilled.

Notes

Chill the entire dessert overnight for the cleanest layers and best flavor.

Use milk chocolate hot cocoa mix for that classic sweet cocoa flavor.

For easier slicing, freeze the dessert for 15–20 minutes before cutting.
