Preheat oven to 350F.
In a large bowl, combine all dry ingredients. Incorporate your wet ingredients and stir just until combined. You want your dough to be just slightly lumpy. It's really important that you do not overmix this batter.
Scoop batter into mini muffin tins that have sprayed with cooking spray. I was able to get 24 mini muffins Bake for 12-15 minutes. You want the muffins to be just slightly brown around the edges.
For the topping, place your melted butter into a small bowl. Combine the sugar and cinnamon into a separate small bowl.
When the muffins are finished baking and are still warm, dip the entire muffin into the melted butter and coat all sides. Then put the muffin into the cinnamon sugar mixture and roll around to cover all sides.
Let cool (if you can wait that long) and enjoy!
