Line a 12-cup muffin pan with paper liners or spray with cooking spray.
In a medium bowl, whisk together sweet rice flour, millet flour, coconut flour, baking powder, baking soda and salt. Set aside.
In another medium bowl whisk together the melted and cooled butter, sugar, eggs, mashed banana and vanilla. Be sure to mash the banana well with a fork - no chunky banana bites!
Use an ice cream scoop to evenly divide batter into muffin tins. Add a few more chocolate chips on top of each one. Bake for about 25 minutes or until a toothpick inserted comes out clean.
Store on the counter in an airtight container for up to four days or freeze.

Notes
When mashing your banana make sure to use a fork and mash it really well. Banana chunks in muffins just aren't good.
The only flour substitution that might work is to use 1 ½ cups of Bob's Red Mill 1 to 1 Baking Flour. I have not tried that yet but it should work.
These can be frozen for breakfast next week. Just put each on into it's own plastic bag. Let thaw overnight in fridge or microwave for 20-30 seconds.
