Full Ingredients

Peanut Butter Cream

• 2 cups heavy cream, cold

• 1 cup creamy peanut butter (no-stir)
• 3/4 cup confectioners’ sugar
• 1 tsp vanilla extract
• 1/2 tsp kosher salt

Crunchy Peanut Topping

• Extra flaky salt for finishing (optional)

Step-by-Step Instructions

Step 1: Prep the pan and ingredients

Line a 9-inch square baking pan with a parchment sling, leaving overhang on two sides for easy lifting. Ensure the cream cheese is at room temperature and the heavy cream for the filling is well chilled. Have your graham crackers, chopped chocolate, and peanuts ready to go.

Step 2: Whip the cream and make the peanut butter base

In a chilled bowl, whip 2 cups cold heavy cream to soft peaks (about 2–3 minutes with a mixer on medium). In a separate large bowl, beat the cream cheese, peanut butter, confectioners’ sugar, vanilla, and kosher salt until smooth and fluffy, 1–2 minutes. Gently fold the whipped cream into the peanut butter base in two additions until no streaks remain. Keep refrigerated while you make the ganache.

Step 3: Make the silky ganache

Heat 3/4 cup heavy cream in a small saucepan over medium until steaming and just beginning to simmer around the edges, 180°F/82°C (do not boil). Pour over the chopped chocolate and add 1 tbsp butter. Let sit 2 minutes, then whisk from the center outward until glossy and smooth. Whisk in 1 tsp vanilla. If needed, keep warm and pourable by setting the bowl over a pan of warm water.

Step 4: Cook the crunchy peanut topping

In a small skillet over medium heat, melt 1 tbsp butter. Add the chopped peanuts and brown sugar; cook, stirring, 2–3 minutes until the sugar dissolves and coats the nuts and they look shiny and lightly toasted. Scrape onto a plate to cool completely. Sprinkle with a pinch of flaky salt if you like.

Step 5: Build the layers

Arrange a single, tight layer of graham crackers in the pan (break pieces to fit). Spread about one-third of the peanut butter cream over the crackers. Drizzle or spoon roughly one-third of the ganache over the cream (about 1/3 cup), then repeat for two more layers: crackers, cream, ganache. Finish with a final layer of cream and a thin ganache swirl on top. You should have three full layers of crackers and three layers of cream with ganache between.

Step 6: Chill until set

Cover the pan tightly and refrigerate at 37–40°F for at least 6 hours, ideally 8–24 hours. This lets the crackers soften into cakelike layers and the cream and ganache fully set.

Step 7: Finish and serve

Unmold by lifting with the parchment sling. Scatter the cooled peanut crunch over the top and finish with a pinch of flaky salt if desired. Slice into 12 squares with a long, sharp knife; dip the knife in hot water and wipe dry between cuts for clean layers. Serve chilled.

Pro Tips

• Use no-stir creamy peanut butter so the filling stays stable and silky.
• Chill your mixing bowl and beaters for faster, fluffier whipped cream.
• Keep ganache warm-but-not-hot for easy drizzling; aim for about 90–95°F (32–35°C).
• For ultra-neat slices, freeze the cake 15 minutes before cutting and use a hot, dry knife.
• Line the pan with a parchment sling—this makes lifting and plating a breeze.

Variations

• Mocha twist: Add 2 tsp instant espresso powder to the hot cream for the ganache.
• Banana split vibe: Layer thinly sliced bananas over each cracker layer (toss slices with a little lemon juice to slow browning).
• Gluten-free: Use gluten-free graham crackers or thin gluten-free vanilla cookies.

Storage & Make-Ahead

Assemble up to 24 hours ahead and chill until serving. Leftovers keep well, covered and refrigerated, for 4 days. For longer storage, freeze tightly wrapped slices for up to 1 month; thaw overnight in the fridge. Add the peanut crunch just before serving so it stays crisp.
