Cinnamon Sugar Donut Muffins

Read the ingredients 5 times to make sure I had it all - more like a kneadable dough than muffin batter. Ended up nearly doubling the milk.

As written this is a pretty good recipe. I tried a batch using bobs red mill 1:1 gluten free baking flour and flaxseed to replace the egg. It was OK at best. Would probably rather find a different allergy friendly version recipe.
