After literally months of muffins, I think I have the recipe down. These are kid friendly with no sugar and dad friendly with real flavor. They tend to go pretty quickly in our house, so you may think about doubling the recipe.
Banana Sweet Potato Muffins
1 sweet potato (I use a medium sized Japanese sweet potato)
4 smallish ripe bananas
1/3 cup oil (I used Safflower or canola oil)
1 egg
1.5 tsp vanilla extract
1 tsp baking powder
1 tsp baking soda
1 tsp cinnamon
1 Tbs All Spice
1 cup spelt flour
Directions
Heat the oven to 350
Peel and roughly chop the sweet potato
Steam the potato (I use my Beaba Babycook) and then purée into a sweet potato mash
Use the KitchenAid and mix the bananas, oil, egg, vanilla, and potato. Blend thoroughly.
Add in the baking powder, soda, spices, and flour. Mix until the batter is smooth.
Line a muffin pan with cases.
Fill up each case to the very top. This should make 12 muffins.
Bake for about 40-45 minutes. Cool and store!
*** Update *** I've recently made a batch with 2 grated carrots mixed in the batter. Yum. Enough said.
