Grain Free, Gluten Free, Banana PB muffins

Wow, that's a mouthful.  I combined a few ideas I found online and created these gems today.  And they are delicious.  I've been gluten free for over a year now but my alternative doc recommended I try grain free a few months ago so I am always looking for ideas.....of things that taste good.  I'm not into eating cardboard.

1 c. peanut butter (yes, another nut butter would be healthier but I looooove pb!)
2 very ripe bananas
2 organic eggs
1 t. Bragg's apple cider vinegar
1 1/2 t. vanilla
1/2 t. baking soda
3 T. pure maple syrup

Throw all this in the BlendTec and blend until smooth.  (eggs first makes it easier to blend)
Spoon into muffin tins and bake for 15 min. at 375.  This recipe makes 12 muffins.
Enjoy!
