Ingredients
- 1 cup creamy peanut butter
- 2 cups heavy whipping cream
- 1/3 cup powdered sugar
- 3 medium ripe bananas
- 24 whole crackers graham crackers
Instructions
- Step 1: In a large mixing bowl, beat 2 cups heavy whipping cream and 1/3 cup powdered sugar on medium-high speed with a hand mixer until stiff peaks form, about 3-4 minutes.
- Step 2: In a separate bowl, combine 1 cup creamy peanut butter with 1/2 cup of the whipped cream, folding gently until smooth and fully incorporated.
- Step 3: Peel and slice 3 medium ripe bananas into 1/4-inch thick rounds.
- Step 4: In a 9x9-inch square pan, spread a thin layer of the peanut butter whipped cream mixture evenly on the bottom. Arrange a single layer of graham crackers (about 8 crackers) over the cream.
- Step 5: Spread half of the remaining peanut butter whipped cream over the crackers, then layer half of the banana slices evenly on top.
- Step 6: Repeat layering with another 8 graham crackers, the remaining peanut butter cream, and the remaining banana slices.
- Step 7: Top with the remaining 8 graham crackers and spread the remaining 1/2 cup whipped cream over the top layer. Cover with plastic wrap and refrigerate for at least 4 hours or overnight to soften the crackers and meld flavors.
- Step 8: Slice into squares and serve chilled.
