Preheat oven to 375° and grease mini muffin tins*. (Makes about 48)
Combine the flour, sugar, brown sugar, baking soda, salt and cinnamon in a medium sized mixing bowl; set aside.
1 3/4 cups flour, 1 cup sugar, 1/2 cup brown sugar, 1 teaspoon baking soda, 1/2 teaspoon salt, 1 tablespoon ground cinnamon
In a large mixing bowl, whisk together the eggs, sweet potato puree, applesauce, and the melted (and slightly cooled) butter.
2 eggs, 1 1/3 cups pureed sweet potato, 1/2 cup applesauce, 1/2 cup butter
Stir in the dry ingredients and mix until just combined. (Don't overmix; batter will be thick)
Fill each muffin tin cavity about 3/4 full.
Bake for 10-12 minutes, or until the a toothpick comes out clean (or with some moist crumbs stuck to it - but no gooey batter).
Let cool for a couple minutes before removing from the pan; let cool completely.
Combine the cinnamon and sugar. Roll the mini muffins into the mixture and serve!
1/2 cup sugar, 1/2 tablespoon ground cinnamon
