These fluffy cinnamon sugar donut muffins offer the perfect balance of airy softness and a slightly crunchy, cinnamon-sweet crust. Easy to make ahead and perfect for a cozy breakfast or snack.
Do not overmix the batter to keep muffins fluffy. Coat muffins immediately after baking while warm for the best cinnamon sugar crust. Use room temperature ingredients for best results. For dairy-free, substitute milk with almond or oat milk and butter with coconut oil. For gluten-free, use a 1:1 gluten-free baking flour blend.
