Preheat oven to 375 degrees and line a mini muffin tin with liners.
In a large mixing bowl combine all wet ingredients – bananas, peanut butter, eggs, maple syrup, milk, and vanilla. Use a mixer to fully blend. Add in dry ingredients and stir well by hand.
Scoop batter into muffin liners and call your littles to come and sprinkle on chocolate chips if you desire to add that touch of sweet.
Bake for 20 minutes or until the tops are golden brown and a toothpick comes out clean. Allow to cool for 10 minutes and then gobble down a few.
