These Mini Cinnamon Sugar Donut Muffins are soft, fluffy, and coated in a classic cinnamon-sugar finish that tastes just like a bakery-style donut. Perfect for breakfast, brunch, or a sweet snack, this easy baked treat delivers rich cinnamon flavor without frying, making it quick, beginner-friendly, and irresistible.
These muffins taste best when fresh and warm, but they can be stored in an airtight container at room temperature for up to 2 days.
For extra richness, you can add a pinch of nutmeg to the batter.
If making ahead, reheat briefly in the microwave for a soft, fresh-from-the-oven feel.
Avoid overmixing the batter to keep the muffins light and fluffy.
