Making Peanut Butter-Banana Semifreddo is like crafting a frozen cloud of yum! Follow these steps for a perfect dessert:
- Prep the Pan:
- Spray a 9×5-inch metal loaf pan with nonstick cooking spray.
- Line with plastic wrap, leaving a 2-inch overhang on all sides, and spray the plastic wrap.
- Tip: Smooth out wrinkles in the plastic for a neat shape.
- Make the Crust:
- In a food processor, finely grind 1/4 cup roasted peanuts and 5 graham cracker sheets.
- Add 4 tbsp melted butter and pulse until combined.
- Press the mixture evenly into the bottom of the prepared pan.

- Place the bowl over the simmering water (don’t let it touch the water) and whisk constantly until thickened, 8-10 minutes.
- Remove from heat and place the bowl in the ice water to cool, stirring occasionally.
- Tip: The custard should coat the back of a spoon when ready.
- Whip the Cream:

- Gently fold the whipped cream into the cooled banana custard until combined.
- Tip: Fold slowly to keep the mixture light and airy.
- Add Peanut Butter:
- Microwave 3/4 cup peanut butter for about 20 seconds until soft, then let cool slightly.
- Drop spoonfuls of peanut butter into the banana cream and fold gently to create swirls.

- Spread the mixture evenly over the chilled crust in the loaf pan.
- Cover with plastic wrap and freeze until firm, at least 9 hours or overnight.
- Tip: Smooth the top with a spatula for a clean look.
