One of my tried-and-true recipes is for apple-blueberry bread. I first got the recipe from Mott's, so it called for Mott's unsweetened applesauce, but I use homemade applesauce. It's on the Web on Spike & Jamie's site, where it calls for "regular" applesauce.
I can't paste in these forums, so I'm hand-copying the URL. When you get to the page, just find the phrase on the page. If you're making muffins, adjust the baking time.
And lest you have any low-fat fantasies, the recipe calls for butter.
