Ingredients

Scale

For the Oreo Crust:

  • 36 Oreo cookies (with filling)
  • ½ cup unsalted butter, melted

For the Hot Chocolate Cheesecake Mousse Layer:

  • ½ cup unsalted butter, softened
  • 8 oz. cream cheese, softened
  • 1 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 5 envelopes (0.73 oz each) instant hot cocoa mix (milk chocolate flavor)
  • 1 ½ cups heavy whipping cream

For the Chocolate Pudding Layer:

  • 2 boxes (3.8 oz each) chocolate instant pudding mix
  • 2 ¾ cups milk
  • 1 cup mini marshmallows

For the Topping:

  • 1 ¼ cups heavy whipping cream (or 2 ½ cups whipped cream)
  • 2 tablespoons powdered sugar
  • 2 cups mini marshmallows
  • Chocolate topping or Nutella (for serving)

Instructions

  1. Making the Oreo Crust: Using a food processor, finely grind the Oreo cookies into crumbs. Stir in the melted butter until evenly moistened. Firmly press the mixture into the bottom of a 13 x 9-inch casserole dish. Chill in the fridge or freezer to set while preparing other layers.
  2. Preparing the Hot Chocolate Cheesecake Mousse Layer: Beat softened butter, cream cheese, powdered sugar, vanilla extract, and instant hot cocoa mix until smooth and creamy. In a separate bowl, whip heavy cream to stiff peaks. Fold half the whipped cream into the cheesecake mixture, then fold in the remaining half gently to combine. Spread this mousse evenly over the chilled Oreo crust and refrigerate to set.
  3. Making the Chocolate Pudding Layer: Whisk chocolate pudding mix with milk until it begins to thicken. Gently stir in mini marshmallows. Spread this pudding layer over the set mousse layer and return to the fridge or freezer to firm up.
  4. Preparing the Whipped Cream Topping: Beat heavy whipping cream and powdered sugar until stiff peaks form. Once the pudding layer is firm, spread the whipped cream evenly over the top.
  5. Finishing Touches: Sprinkle mini marshmallows atop the whipped cream. For extra indulgence, drizzle melted chocolate or Nutella over the dessert before serving. Allow the lasagna to chill well before slicing and enjoying.

Notes

  • For a stronger hot chocolate flavor, double the instant hot cocoa mix in the mousse layer but be cautious as it may affect texture.
  • Substitute the Oreo crust with graham cracker crust or any chocolate cookie crust if preferred.
  • This dessert is ideal for making ahead; chilling overnight yields the best texture.
  • Try festive variations like crushed peppermint candies, caramel drizzle, or chocolate shavings on top.
  • You may make homemade chocolate pudding instead of using instant mix for a scratch version.
