Go Bananas!

When baking, replace the fat called for in a recipe with mashed ripe bananas, fruit or squash puree, plain, fat free yogurt, or low-fat cottage cheese. Use a substitute that will compliment the baked item you are making; bananas are great for pancakes and applesauce works well for most quick breads.

For the measurements, 3 mashed bananas can replace 1/2 to 3/4 cup; the other substitutes can be measured 1 for 1. If you don't like how it turns out, only replace 1/2 or 3/4 of the fat and see if that is any better.
