Preheat oven to 400 degrees F.
In a medium bowl, mix together all the dry ingredients, leaving out the nuts.
In a large mixing bowl, add bananas, and mash with a fork. Add the rest of the wet ingredients, and stir to combine, leaving the bananas a bit chunky.
Add the dry ingredients and the pecans to the wet ingredients, and stir to combine, without over mixing.
Line a muffin pan with cupcake liners, and then fill each liner with batter. This recipe will make 12 muffins if you fill them 3/4 of the way, or about 9-10 if you slightly overfill them like I do.
Bake muffins for 18-20 minutes, until the tops are slightly browned and they are fully cooked in the centers.
Allow to cool. Store at cool room temperature or in the refrigerator.
