The image shows a multi-layered chocolate dessert with a clear cross-section, revealing four distinct layers. The bottom layer is a dense dark brown cookie crust, crumbly in texture. Above it is a thick, creamy light brown chocolate mousse layer that looks smooth and soft. The third layer is a shiny, darker chocolate ganache with small marshmallow pieces mixed in, adding texture. The top layer is a bright white whipped cream topped with many small, fluffy white mini marshmallows, covering the surface evenly.

Ingredients

36 Oreo cookies (ground)
½ cup unsalted butter, melted
½ cup unsalted butter, softened
8 oz. cream cheese, softened
1 cup powdered sugar
1 teaspoon vanilla
5 (0.73 oz) envelopes instant hot cocoa mix (milk chocolate flavor)
1 ½ cups heavy whipping cream
2 (3.8 oz) chocolate instant pudding mix
2 ¾ cups milk
1 cup mini marshmallows
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

Step 1: Place whole Oreo cookies with the filling in a food processor and grind into fine crumbs. Stir in the melted butter and press the mixture into the bottom of a 13 x 9-inch casserole dish. Refrigerate or freeze to firm while preparing the next layer.
Step 2: Beat the softened butter and cream cheese with vanilla and powdered sugar until creamy and smooth.
Step 3: In another bowl, beat the 1 ½ cups heavy whipping cream and instant milk chocolate powder (from the cocoa mix) until stiff peaks form. Fold half of this hot chocolate whipped cream into the cream cheese mixture, then fold in the remaining half. Scrape the bottom of the bowl to mix well, then spread over the Oreo crust. Chill until firm.
Step 4: In a separate bowl, whisk the chocolate instant pudding mix with milk until it begins to thicken. Stir in 1 cup of mini marshmallows and spread this pudding layer over the set hot chocolate mousse layer. Chill again until set.
Step 5: Beat the 1 ¼ cups heavy whipping cream with 2 tablespoons powdered sugar until stiff peaks form. Spread this whipped cream evenly over the pudding layer and refrigerate for a few hours or preferably overnight.
Step 6: Before serving, scatter 2 cups of mini marshmallows over the whipped cream layer.
Step 7: Drizzle with melted chocolate, Nutella, or your favorite chocolate topping and serve.
Step 8: Store any leftovers in the refrigerator.

Tips & Variations

For a richer dessert, use dark chocolate pudding and bittersweet cocoa powder in place of milk chocolate.
Try adding crushed peppermint candies on top for a festive touch in winter.
If you don’t have a food processor, place Oreo cookies in a sealed plastic bag and crush with a rolling pin.
Use homemade whipped cream for a fresher taste instead of store-bought.
For a lighter version, substitute half the heavy cream with Greek yogurt in the mousse layer.

Storage

Store hot chocolate lasagna covered in the refrigerator for up to 3 days. This dessert is best enjoyed chilled. Rewarming is not recommended, but you can let it sit at room temperature for 10-15 minutes before serving if too firm from the fridge.

FAQs

Can I make this dessert ahead of time?

Yes, hot chocolate lasagna benefits from sitting overnight in the refrigerator as it allows the layers to set fully and flavors to meld.

Can I use a different cookie for the crust?

Absolutely! While Oreo cookies create a classic chocolate crust, you can substitute with other chocolate wafer cookies or even graham crackers for a different flavor and texture.
