Preheat the oven to 350°F (160C). Spray a standard loaf pan with cooking spray, line with parchment, and spray again with cooking spray.
Beat the butter, sugar, and California Prune Purée in a large bowl until light and fluffy. Add the eggs, one at a time, beating after each addition until smooth.
Add the flour, baking powder, and salt and beat once or twice to mix. Then add the banana and sesame seeds and continue to beat until all ingredients are well combined.
Pour the mixture into the prepared loaf pan and sprinkle additional sesame seeds on top if desired. Bake for 55 minutes or until a toothpick inserted in the center of the loaf comes out clean.
