Here's a handy tip I learned a while ago, it's probably fairly common knowledge, but it's still a good tip. As a way to cut down on fat in baked goods substitute the oil you are supposed to put in with applesauce.
I'm making some lemon poppy seed muffins as I write. The recipe called for 1/4 cup of vegetable oil. Instead I put 1/4 cup of applesauce. It works great for cake, keeps it nice and moist and doesn't affect the way it tastes or looks. :) I've also substituted applesauce for vegetable oil in waffles. Haven't tried pancakes but I'm assuming it would work fine.
That's my trick of the week? What tricks do you use for healthier baking/cooking without losing flavor??
