Instructions
- Step 1: In a large bowl, combine 1 cup creamy peanut butter and 1/2 cup powdered sugar. Whip together with an electric mixer on medium speed for 2 minutes until smooth and fluffy.
- Step 2: In a separate chilled bowl, whip 1 cup heavy cream to stiff peaks, about 3-4 minutes on high speed.
- Step 3: Gently fold the whipped 1 cup heavy cream into the peanut butter mixture until fully combined and light.
- Step 4: Slice 2 medium ripe bananas into 1/4-inch thick rounds.
- Step 5: In a 9x5-inch loaf pan, layer 3 graham crackers flat on the bottom. Spread one-third of the peanut butter mousse evenly over the crackers, then add a layer of banana slices covering the mousse.
- Step 6: Repeat layering two more times with 3 graham crackers, mousse, and bananas, ending with a final layer of graham crackers on top.
- Step 7: Cover the loaf pan with plastic wrap and refrigerate for at least 4 hours or overnight until firm and the crackers soften to cake-like texture.
- Step 8: To serve, slice into 1-inch thick pieces and enjoy the creamy, fruity, and crunchy combination.
