This fabulous recipe was discovered by Ms. Mommy after a google search for "peanut butter and banana muffins". It's from the lovely blog Once A Month Mom. It's a very simple recipe for whipping up a quick batch of tasty muffins.
The recipe, along with her inspiration for it and batter freezing instructions, is found here http://onceamonthmom.com/peanut-butter-banana-muffins/
Ms. Mommy added extra banana, and baked the muffins a bit longer than recommended because of it, but considers these a success because she managed not to burn or otherwise completely ruin them. They were a HUGE hit! Hank even devoured two whole muffins.
