Ingredients

Scale

Making this dessert is like gathering a few familiar friends to create something unforgettable. I often keep these ingredients on hand, and I love how flexible some substitutions can be depending on what I have in the pantry.

  • 1 cup creamy peanut butter (natural or processed, depending on your preference; natural for a less sweet, more intense peanut flavor)
  • 8 oz (1 package) cream cheese, softened (for a richer flavor, you can substitute Greek yogurt cream cheese)
  • 1 cup powdered sugar (sifted to eliminate lumps, but honey or maple syrup can be used as a natural sweetener alternative)
  • 1 teaspoon vanilla extract
  • 2 cups heavy whipping cream (or coconut cream for a dairy-free version)
  • 1 package (about 12 oz) graham crackers or digestive biscuits (for that classic layered look; vanilla wafers work too)
  • 1 1/2 cups milk (for dipping the crackers; you can substitute almond milk or oat milk)
  • 1 cup mini chocolate chips (optional, but I love a sprinkle for a little extra indulgence)
  • Chopped peanuts or additional mini chocolate chips for garnish (optional but highly recommended)

When I first made this, I used store-bought graham crackers, but I’ve also experimented with homemade versions, which add an extra touch of love. Feel free to swap ingredients based on your dietary needs or what’s in your pantry—this dessert is all about making it work for you.

Instructions

  1. Begin by preparing the creamy peanut butter filling. In a large mixing bowl, beat the softened cream cheese until smooth and fluffy. I usually do this with a hand mixer for about 2 minutes, which also helps to eliminate any lumps.
  2. Add the peanut butter, powdered sugar, and vanilla extract to the cream cheese. Mix until fully combined and creamy. This step always reminds me of baking cookies with my grandma—simple ingredients coming together to create something special.
  3. In a separate bowl, whip the heavy cream until stiff peaks form. I prefer to do this with a hand or stand mixer on medium-high speed for about 3-4 minutes. The whipped cream adds that light, airy texture that balances the richness of the peanut butter.
  4. Gently fold the whipped cream into the peanut butter mixture, using a spatula. Be careful not to overmix—folding preserves that fluffy texture which makes every bite melt in your mouth.
  5. Next, prepare your dipping liquid. Pour the milk into a shallow dish. Quickly dip each graham cracker into the milk, just enough to soften them slightly—about 1-2 seconds per side. I learned this trick from my grandma’s recipe box; it prevents the crackers from becoming too soggy while still making them easy to layer.
  6. Start assembling your lasagna in a 9×13-inch dish. Place a layer of dipped graham crackers at the bottom. Spread half of the peanut butter filling evenly over the crackers.
  7. Add another layer of dipped graham crackers on top of the filling, then spread the remaining peanut butter mixture over this second layer.
  8. Finish with a final layer of dipped graham crackers. If desired, sprinkle mini chocolate chips and chopped peanuts on top for extra flavor and crunch.
  9. Cover the dish with plastic wrap and refrigerate for at least 4 hours, or ideally overnight. This allows the flavors to meld beautifully and the layers to set, making it easier to slice neatly.
  10. Before serving, I like to add a few more chocolate chips or a drizzle of melted chocolate on top. It’s a little touch that elevates the presentation and adds that extra bit of decadence I love.
