Preheat oven to 375 degrees. Line a 12 cup muffin tin with muffin liners, or generously grease a muffin tin with cooking spray.
With a fork or pastry knife, mash up your bananas (no chunks) and place in a large bowl. Add peanut butter, honey, maple syrup, yogurt, milk, egg, and vanilla extract. Beat with an electric mixture until smooth. Set aside.
In a medium bowl, mix together the remaining (dry) ingredients. Add the dry ingredients to the wet, and mix with a rubber spatular until well combined and the flour pockets have disappeared.
Fill muffin cups to about ¾ full (or more if you have leftover batter).
Bake for 15-18 minutes or until the tops are golden brown and a toothpick inserted in the middle comes out clean. Mine take right around 16 minutes!
