Self Rising Flour Cinnamon Muffins

I used half Greek yogurt and half milk for this recipe, and reduced the butter a bit. I also only sprinkled cinnamon sugar over the tops of them before baking instead of rolling them in sugar afterwards

I added 1tsp of vanilla and 1/3 cup chopped walnuts. For the topping I made a honey buttercream glaze and sprinkled more walnuts on top. Delicious! Easy too!
