Most pancake mixes are simply made up of flour, baking powder, sugar, and salt. So, if you're using a pancake mix to make banana bread, you have 3 ingredients in one (you'll want to add more sugar).
You can use any brand of pancake mix for this banaan bread! I've tested it with both Annie's Organic and Bisquick, but you can also use Aunt Jemima (Pearl Mill), Krusteaz, Hungry Jack, & more.
