Chocolate Banana Bread

I found this recipe on www.recipegirl.com and I'm going to make a few changes to it...

• Ready In: 1 hr 10 mins
• Serves: 12
• Yields: 12 slice

Ingredients

• 1 1⁄4 cups prunes, unsweetened baby food
• 3⁄4 cup banana, mashed (about 2 medium)
• 4  large  egg whites
• 1  cup whole wheat pastry flour
• 1⁄2 cup  unsweetened cocoa powder
• 2  teaspoons baking powder
• 2  teaspoons instant coffee
• 1 1⁄2 teaspoons baking soda
• 1  cup  semi-sweet chocolate chips

Directions

1. Preheat oven to 350°F Lightly butter a 5×9-inch loaf pan and line bottom with a piece of parchment paper, cut to fit.
2. Beat prunes and bananas until very smooth. Add eggs and whirl to combine.
3. In a large bowl, sift together flour, cocoa, baking powder, instant coffee, and baking soda. Stir in banana mixture until evenly moistened. Stir in chocolate chips. Scrape the thick batter into pan and spread level.
4. Bake bread until a toothpick inserted in the center comes out a little chocolatey but not gooey, 40 to 50 minutes. Loosen bread from pan with a knife and invert onto a rack. Remove parchment. Turn bread right-side-up and let cool at least 1 hour before slicing.
