Not the standard banana muffin, but if eating healthy is a priority, try this out with your own substitutions. This did not have the normal sweetness to it as I reduced the added sugar considerably. I would have added dates if I had them on hand.
My recipe.
1C Oats
1C Rye Flour
1/2 C All Purpose Flour
1/2 Baking Soda
1t Baking Powder
2t Cinnamon
3T brown sugar
3/4C raisins
1/4C chopped nuts
3 overripe bananas
Milk as necessary
3t Ghee/butter
Mix all dry ingredients in a bowl. Mash bananas in another bowl and add the melted ghee to it. Add the dry ingredients slowly and fold into the banana mixture. If it is too thick, add some milk. Fold in the rest of the dry ingredients. Bake in mini muffin tin at 375F for approx 20 mins.
