Frozen Peanut Butter, Chocolate, and Banana Loaf

from Martha Stewart (Everyday Food 2005)
Ingredients:
-1 (12 oz) bag semisweet chocolate chips
-3/4 cup peanut butter (I used crunchy)
-2 ripe bananas
-1 cup heavy cream, whipped to stiff peaks
-1/2 cup chopped unsalted peanuts

Directions:
1. Spray a loaf pan with cooking spray and line with wax paper, leaving an overhang on both sides. Set aside.
2. Melt chocolate in a double boiler. Set aside to cool to room temperature. While chocolate is cooling, puree bananas in food processor. Stir peanut butter and bananas into cooled chocolate mixture. Fold in whipped cream, mixing to combine.
3. Pour mixture into the prepared pan. Top with peanuts. Fold wax paper over the top before wrapping in plastic wrap. Freeze until firm, at least 3 hours.
