Ingredients
Oreo Crust
- 36 Oreo Cookies: The crust is made by grinding up Oreos, filling and all. The rich chocolate flavor of the cookies serves as the perfect base, providing a slight crunch that complements the creamy layers above.
- 1/2 Cup Unsalted Butter: The melted butter binds the Oreo crumbs together, ensuring the crust sets nicely. It also adds a rich flavor that enhances the chocolatey base.
Hot Chocolate Cheesecake Mousse Layer
- 1/2 Cup Unsalted Butter and 8 oz. Cream Cheese: These create a creamy, smooth base for the mousse, giving it a rich texture that melts in your mouth.
- 1 Cup Powdered Sugar: Sweetens the mousse and helps to stabilize the cream cheese and butter mixture, contributing to its smooth texture.
- 1 Teaspoon Vanilla Extract: Adds warmth and depth to the mousse.
- 5 Envelopes (0.73 oz) Instant Hot Cocoa Mix (Milk Chocolate Flavor): This is what gives the mousse its hot chocolate flavor. It adds sweetness, a deep chocolate taste, and a touch of richness.
- 1 1/2 Cups Heavy Whipping Cream: When whipped, this adds a light, airy texture to the mousse, balancing out the density of the cream cheese and butter.
Chocolate Pudding Layer
- 2 Packages (3.8 oz) Instant Chocolate Pudding Mix: This creates the creamy, decadent pudding layer that adds another layer of richness.
- 2 3/4 Cups Milk: This is combined with the pudding mix to create a smooth, thick pudding layer.
- 1 Cup Mini Marshmallows: The marshmallows add a touch of sweetness and whimsy to the pudding, making it even more reminiscent of hot chocolate.
Whipped Cream Topping
- 1 1/4 Cups Heavy Whipping Cream: This forms the base of the whipped cream topping. It’s light, fluffy, and the perfect final touch to this dessert.
- 2 Tablespoons Powdered Sugar: Adds a bit of sweetness to the whipped cream, helping to balance out the rich layers beneath.
- 2 Cups Mini Marshmallows: These marshmallows are scattered on top, adding both texture and a touch of nostalgia.
Optional Chocolate Topping
- Chocolate Topping or Nutella: This optional drizzle adds a final layer of chocolate indulgence, enhancing the dessert’s appearance and providing a glossy finish.
Instructions
Step 1: Prepare the Oreo Crust
- Crush the Oreos: Start by placing the whole Oreo cookies (filling and all) in a food processor and pulse until they turn into fine crumbs. This is your crust base.
- Add Butter: Melt the unsalted butter and stir it into the Oreo crumbs. This will help the crumbs stick together when pressed into the pan.
- Press Into the Dish: Press the Oreo mixture into the bottom of a 13×9-inch casserole dish. Make sure to press it down evenly and firmly to create a solid crust.
- Chill: Place the crust in the fridge or freezer to firm up while you work on the next layers.
Step 2: Make the Hot Chocolate Cheesecake Mousse Layer
- Beat Cream Cheese and Butter: In a large mixing bowl, beat together the softened butter and cream cheese until smooth. Add in the vanilla extract and powdered sugar, mixing until fully combined.
- Whip the Heavy Cream: In a separate bowl, whip the heavy whipping cream and instant hot cocoa mix until stiff peaks form.
- Combine the Mixtures: Gently fold half of the whipped cream into the cream cheese mixture, followed by the remaining whipped cream. Be gentle to avoid deflating the whipped cream.
- Spread Over Crust: Once everything is combined, spread this fluffy mousse layer over the chilled Oreo crust. Return the dish to the fridge or freezer to set.
Step 3: Prepare the Chocolate Pudding Layer
- Make the Pudding: In a large mixing bowl, whisk the instant chocolate pudding mix and milk together until it begins to thicken. Stir in the mini marshmallows.
- Spread Over Mousse: Spread the thickened pudding layer evenly over the cheesecake mousse layer. Chill again in the fridge or freezer to set.
Step 4: Make the Whipped Cream Topping
- Whip the Cream: Beat the heavy whipping cream with powdered sugar until stiff peaks form.
- Spread Over Pudding: Once the pudding layer has set, spread the whipped cream over the pudding, smoothing it out to cover the entire surface.
Step 5: Garnish and Serve
- Add Marshmallows: Sprinkle the mini marshmallows over the whipped cream topping.
- Drizzle with Chocolate: For an extra touch of decadence, drizzle with chocolate topping or Nutella.
- Chill Before Serving: Allow the dessert to chill in the fridge for at least a few hours, preferably overnight, so the layers firm up and the flavors meld together.
Notes
- Storage: Hot Chocolate Lasagna can be made ahead of time and stored in the fridge for up to 2-3 days. Just be sure to store it tightly covered.
- Substitutions: You can use chocolate-flavored graham crackers instead of Oreos for the crust, or even swap the pudding mix for a homemade chocolate pudding.
- Serving Ideas: This dessert is already quite indulgent, but you can take it up a notch by adding a scoop of vanilla ice cream or a drizzle of caramel sauce.
- Marshmallow-Free: If you’re making this in advance, omit the marshmallows from the pudding layer, as they can become soggy over time.
The beauty of this dessert lies in its simplicity. No need to bake or fuss with complicated techniques. Instead, Hot Chocolate Lasagna comes together in layers, each one offering a new taste sensation. From the crunch of the Oreo crust to the creamy hot chocolate cheesecake mousse and the rich chocolate pudding layer, it’s an experience that feels indulgent without being overly complicated.
