No-Bake Peanut Butter Lasagna Ingredients

For the Crust
• Crushed Graham Crackers or Nutter Butters – Use Nutter Butters for enhanced peanut flavor; graham crackers offer a milder base.
• Chopped Peanuts – Adds a delightful crunch; optional but highly recommended for texture.
• Unsalted Butter – Binds crust ingredients together; melt for a perfect mix.

For the Ganache
• Semi-Sweet Chocolate Chips – Creates a rich layer; swap in dark chocolate for a deeper flavor.
• Heavy Cream – Essential for a velvety ganache; can use half-and-half, but it will slightly change the texture.

• Cream Cheese – The base that gives the mousse its creamy texture; ensure it’s softened for easy blending.
• Peanut Butter – The star of this no-bake peanut butter lasagna; just stir well before measuring if using natural peanut butter.
• Powdered Sugar – Sweetens the mousse; granulated sugar works too, but may alter texture.
• Vanilla Extract – Enhances the overall flavor; opt for pure for the best results.
• Whipped Topping (Cool Whip) – Lightens the mousse; for a fresher option, whip heavy cream as a substitute.

For the Chocolate Mousse
• Chocolate Pudding Mix – Provides the chocolate layer; use your favorite flavor and mix with cold milk until thick.
• Cold Milk – Essential for mixing the pudding; gives the mousse the right texture.

For Topping
• Additional Whipped Topping – For a smooth finish on top before serving; consider homemade for extra freshness.
• Warm Peanut Butter – Drizzle over the top for added flavor and visual appeal.
• Mini Chocolate Chips and Peanuts – Great toppings for added crunch and sweetness; customize as desired!

How to Make No-Bake Peanut Butter Lasagna

Prepare the Crust: In a mixing bowl, combine crushed graham crackers or Nutter Butters with chopped peanuts and melted butter. Press this mixture firmly into a 9×13-inch dish and place it in the freezer for about 10 minutes to set.
Make Ganache: Heat the heavy cream in a saucepan until it’s hot but not boiling. Pour it over the semi-sweet chocolate chips and stir gently until the chocolate is completely melted and smooth. Let it cool slightly before pouring over your crust. Refrigerate to set for about 30 minutes.
Peanut Butter Cheesecake Mousse: In another bowl, blend the softened cream cheese and peanut butter until smooth. Add powdered sugar and vanilla, mixing until well combined. Gently fold in the whipped topping, and then spread this layer over the cooled ganache.
Chocolate Mousse: In a separate bowl, mix the chocolate pudding mix with cold milk, whisking until the mixture thickens. Then, fold in whipped topping until combined, and spread this luscious chocolate layer over the peanut butter mousse.
Top and Serve: Spread additional whipped topping over the chocolate layer. Drizzle warmed peanut butter on top and sprinkle mini chocolate chips and chopped peanuts for added crunch. Chill the dessert before serving or freeze briefly for neat slices.

Optional: Garnish with crushed pretzels for a touch of saltiness!

Make Ahead Options

These No-Bake Peanut Butter Lasagna layers are perfect for meal prep enthusiasts! You can prepare the crust and the ganache up to 24 hours in advance. Simply combine the crushed graham crackers or Nutter Butters with chopped peanuts and melted butter, then press it into your dish and freeze it. Make the ganache by heating the heavy cream and stirring in the chocolate chips, letting it set in the refrigerator. For the mousse layers, whip them up the same day you plan to serve, folding in the whipped topping just before spreading it over the chilled layers. This not only saves time but ensures every slice maintains that delightful creaminess and crunch!

No-Bake Peanut Butter Lasagna Recipe FAQs

What type of peanut butter should I use?
Absolutely! For this no-bake peanut butter lasagna, I recommend using creamy natural peanut butter for the best texture. Just give it a good stir before measuring, as the oil can separate. If you prefer a more pronounced peanut flavor, feel free to use a crunchy variety!

How should I store leftovers?
You can keep your no-bake peanut butter lasagna tightly wrapped in the refrigerator for up to 5 days. This ensures that the layers stay fresh, flavorful, and creamy. If you anticipate not finishing it within that timeframe, consider freezing it for longer storage.

Can I freeze this dessert for later?
Very! To freeze your no-bake peanut butter lasagna, cut it into individual portions and wrap each slice tightly in plastic wrap. Place them in an airtight container, and they will be good for up to 2 months in the freezer. When you’re ready to enjoy, simply transfer the slices to the fridge to thaw overnight.

What should I do if my cream cheese is lumpy?
If you find that your cream cheese is lumpy, it’s likely not softened enough. For a smooth peanut butter mousse, ensure your cream cheese is at room temperature before mixing. Let it sit out for about 30 minutes, then blend it again. If lumps happen during the mixing process, you can use an electric mixer to help achieve a silky consistency.

Is this dessert pet-friendly?
No, it’s best to keep this no-bake peanut butter lasagna away from pets. While peanut butter can be safe in small amounts for dogs, the added sugars and artificial ingredients in whipped toppings and chocolate ganache can be harmful. For a safe treat for pets, consider using plain, unsweetened peanut butter without any additives.

Can I make it a day in advance?
Absolutely! This no-bake peanut butter lasagna is actually make-ahead friendly. In fact, preparing it a day in advance allows the flavors to meld beautifully, enhancing the overall taste. Just store it covered in the fridge and slice when ready to serve. Enjoy the extra time with your guests!
