Preheat oven to 350 F. Grease two 12-cup muffin tins
Combine all ingredients in one bowl and mix with wooden spoon until incorporated.
Divide batter between 12-18 muffin cups (For 18 small muffins fill cups halfway, for 15-16 larger muffins, fill cups 3/4 full).
Place muffin tin on a baking sheet and bake in preheated oven for 25 minutes.
Cool in pan ten minutes, then remove from pan and cool completely on wire racks.
Place cooling rack of muffins over a sheet of waxed paper. Whisk together glaze ingredients. Drop one tablespoon of glaze on the top of each muffin and allow glaze to drizzle down. Waxed paper will catch the drips. Allow glaze to set up before serving.
