Preheat the oven to 350 degrees, and line cups of a muffin tin with paper liners.
In a blender, spice mill or food processor, grind the oats until they turn into a flour-like consistency. Set aside
In a large bowl, blend bananas, eggs, coconut, vanilla and nut butter until combined. Add the oat flour, spices, baking soda and powder and salt and continue to mix.
Fold in the nuts.
Divide the batter evenly among the muffin cups and bake about 15-18 minutes. You will know they are done when a toothpick inserted in the center of a muffin comes out clean.
Remove the muffins from the oven and allow to cool on a wire rack for about 10 minutes. Remove from the tin to continue cooling.
