Preheat oven to 350 degrees.
Mix wet ingredients in a food processor or mixer - mashed bananas, eggs, pumpkin puree, oil, maple syrup, molasses, and vanilla extract.
Mix dry ingredients in a separate bowl - flour, sugar, gingerbread spices, baking powder, baking soda and salt.
Add dry ingredients to wet ingredients and mix until combined.
Add batter to a muffin tin, with each muffin tin 3/4 full.
Add ~1/2 teaspoon Cinnamon Sugar on top of each muffin.
Bake for 23-25 minutes, or until a toothpick comes out clean.
