These easy cinnamon sugar donut muffins are a cozy, quick breakfast treat with a tender crumb and a sweet, crunchy cinnamon sugar crust. Perfect for busy mornings or a comforting snack.
Do not overmix the batter to keep muffins tender. Brush butter on warm muffins to help cinnamon sugar stick. Use paper liners for easier cleanup. For extra crunch, double dip the muffins in cinnamon sugar. Room temperature eggs and milk improve texture. Test doneness with a toothpick.
