How to Make Hot Chocolate Lasagna

Step 1: Prepare the Oreo Crust

Start by grinding the Oreo cookies (with their filling) into fine crumbs using a food processor. Stir the melted butter into the crumbs until evenly moistened. Press the mixture firmly into the bottom of a 13×9-inch dish to form the crust. Place it in the fridge or freezer to firm up while you work on the next layer.

Step 2: Make the Hot Chocolate Cheesecake Mousse Layer

In a bowl, beat the softened butter, cream cheese, vanilla, and powdered sugar until smooth and creamy. In a separate bowl, whip the heavy cream and instant hot cocoa mix until stiff peaks form. Gently fold the whipped hot cocoa cream into the cheesecake mixture in two additions, ensuring everything is fully combined. Spread the mousse layer over the chilled crust and return the dish to the fridge or freezer.

Step 3: Prepare the Chocolate Pudding Layer

Whisk the chocolate pudding mixes with the milk until it begins to thicken. Fold in the mini marshmallows for a fun, gooey texture. Carefully spread the pudding layer over the mousse layer and set it back into the fridge or freezer to firm up.

Step 4: Whipped Cream Topping

Once the pudding has set, whip the heavy cream and powdered sugar until stiff peaks form (or use pre-made whipped cream). Spread this whipped topping over the pudding layer. Refrigerate for a few hours or, ideally, overnight to allow the dessert to fully set.

Step 5: Final Touches

Before serving, scatter mini marshmallows generously over the top and drizzle with melted chocolate, Nutella, or your favorite chocolate topping.

Tips for Perfect Hot Chocolate Lasagna

Use full-fat dairy for the richest, creamiest layers.
Chill between layers to keep your dessert beautifully defined and easy to cut.
Don’t overwhip the cream when mixing with cocoa powder — whip just to stiff peaks.
Refrigerate overnight if possible for the best flavor and texture.
Use a sharp knife wiped clean between cuts for picture-perfect slices.

Recipe Variations

Peppermint Hot Chocolate Lasagna: Add crushed peppermint candies between layers or a drop of peppermint extract into the mousse.
Nutty Twist: Sprinkle chopped toasted pecans or hazelnuts between the pudding and whipped cream layers.
Spicy Kick: Mix a pinch of cinnamon and cayenne into the hot chocolate mousse for a Mexican hot chocolate vibe.
Cookie Swaps: Use mint Oreos or chocolate graham crackers instead of traditional Oreos for a different flavor profile.

How to Store Hot Chocolate Lasagna

Storage: Keep any leftovers tightly covered in the refrigerator for up to 5 days.

Freezing: You can freeze Hot Chocolate Lasagna for up to 2 months. Wrap it tightly in plastic wrap and foil. Thaw overnight in the fridge before serving. Note: the texture of the whipped topping may change slightly after freezing.

Suggested Food and Drink Pairings

Beverages: Pair with a cup of rich coffee, spiced chai latte, or (of course!) a steaming mug of hot chocolate for the ultimate winter treat.
Food: Serve alongside other festive sweets like peppermint bark, gingerbread cookies, or cinnamon rolls for a decadent dessert buffet.
