Preheat oven to 350 degrees. In a large bowl, mix together all ingredients except for coarse sugar until combined and there are no dry lumps.
Evenly distribute mixture between 12 greased muffin tins or lined with liners. Sprinkle with the coarse sugar on top of each muffin.
Bake 23-28 minutes until a toothpick inserted into the center comes out clean. Let cool 10 minutes in the tin, take out and let cool completely on wire rack.
