Snickerdoodle Muffins

1 1/2 Cups Self-rising Flour
1 Cup Quick-cooking Oatmeal
1/2 Cup Sugar
1 Large Egg
4 Tablespoons Butter, Melted
1 Cup Milk
1 Teaspoon Vanilla Extract
Topping:
1/3 Cup Sugar
1 Teaspoon Cinnamon

Mix all dry ingredients together; flour, oats, 1/2 cup sugar and cinnamon. Mix egg, butter, vanilla and milk together. Add wet mixture to dry mixture until combined, mixing by hand. Fill muffin cup 3/4 full and bake at 400° for 12 to 14 minutes.

While baking, mix the topping together - 1/3 cup sugar, 1 teaspoon cinnamon. Once they are out of the oven, put topping on muffins. If you prefer, brush muffin with some melted butter before you put the topping on, it will help it stick better.
