Soft and fluffy homemade muffins are coated with cinnamon sugar to mimic your favorite donuts in this quick and easy recipe! These Cinnamon Sugar Donut Muffins are a feel-good breakfast that goes great with a hot mug of coffee or a cold glass of milk.
Preheat oven to 350°F. Spray the wells of a muffin pan with non-stick cooking spray; set aside.
In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, and cinnamon for the muffins.
In a medium mixing bowl, whisk together the milk, egg, melted butter, and vanilla. Pour into the dry mixture and stir just until combined.
Fill the muffin pan cups 2/3 full of the batter. Bake at 350F for 20-22 minutes (or 12-14 minutes for mini muffins) until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes, then remove from the pan and allow to continue to cool on a wire cooling rack.
In a small bowl, mix together the sugar and cinnamon for the coating. Dip the muffins in the melted butter then roll in the cinnamon sugar.
Notes
Keep extra muffins in an airtight container or zip-top bag for up to 3 days, either chilled or at room temperature.
