Cinnamon Sugar Muffin
intro
Soft, tender domed muffins coated in buttery cinnamon sugar, with a warm spiced crumb—perfect for cozy breakfasts or sweet casual snacks.
Ingredients
Steps
Prep Oven and Muffin Tin
Preheat your oven to 200°C (400°F) with a rack positioned in the middle. Line a 12-cup standard muffin tin with paper liners, or lightly grease each cup with non-stick spray or a thin butter coating to prevent sticking.
Whisk Dry Batter Ingredients
In a large mixing bowl, combine 240g (2 cups) all-purpose flour, 100g (1/2 cup) granulated sugar, 10g (2 tsp) baking powder, 1g (1/4 tsp) baking soda, 3g (1/2 tsp) fine sea salt, and 2.5g (1 tsp) ground cinnamon. Whisk vigorously for 30 seconds to evenly distribute leavening and spices, breaking up any flour or cinnamon clumps.
Mix Wet Batter Ingredients
In a separate medium bowl, whisk together 1 room-temperature large egg, 180ml (3/4 cup) whole milk, 56g (4 tbsp, half the total) melted and slightly cooled unsalted butter, and 5ml (1 tsp) pure vanilla extract. Whisk for 20 seconds until completely smooth, with no visible streaks of unincorporated egg.
Fold and Portion Batter
Pour the full wet ingredient mixture into the dry ingredient bowl. Use a rubber spatula to fold gently just until no dry flour streaks remain; do not overmix (small lumps are normal and produce tender muffins). Scoop 60ml (1/4 cup) of batter into each lined muffin cup, filling each roughly 2/3 full to leave room for rising.
Bake Muffins Until Golden
Place the muffin tin on the middle oven rack and bake for 18-20 minutes at 200°C (400°F). Test doneness by inserting a wooden toothpick into the center of a middle muffin: it should come out with 1-2 moist crumbs attached, not wet batter. Remove from oven and let muffins rest in the tin for 5 minutes before moving to a wire rack.
Make Cinnamon Sugar Coating
While muffins cool slightly, prepare the topping: in a shallow wide bowl, stir together the remaining 100g (1/2 cup) granulated sugar and 7.5g (3 tsp) ground cinnamon until evenly mixed, with no dark cinnamon clumps. Pour the remaining 57g (4 tbsp) melted, slightly cooled butter into a second shallow bowl.
Coat Muffins and Serve
Working one warm muffin at a time, dip the top and all sides first in melted butter, letting excess butter drip off for 2 seconds, then roll generously in the cinnamon sugar mixture to coat all buttered surfaces evenly. Set coated muffins back on the wire rack for 2 minutes to set before serving warm.
Tips
2.Coat muffins during the 5-minute post-bake warm window (not piping hot straight from the oven) so the butter adheres properly and the cinnamon sugar sticks evenly without sliding off.
3.Store leftover cooled muffins in an airtight container at room temperature for up to 3 days; reheat for 10 seconds in the microwave before serving to restore their soft, fresh-baked texture.

Made these for our neighborhood potluck last weekend and people were begging for the recipe! My kids loved them so much they asked me to make a second batch for their after-school snacks this week. The cinnamon sugar crust is so perfectly crispy on top and the muffin itself is so fluffy, not dry at all. Cook time was totally spot on at 35 minutes, I didn’t have to adjust my oven temp at all. SO good, will absolutely make again!
Wait, can I use regular granulated sugar if I don’t have coarse sugar for the topping? I’ve been nervous to try muffin recipes because I always mess them up, but this looks too easy to pass up!
These are the perfect pairing for my morning latte! I did end up adding a tiny splash of vanilla extract to the batter because I love that extra warm flavor, and it worked so well. My only tiny note is that my muffins stuck a little to the paper liners – any tips for that next time?
I’m usually a savory breakfast guy, but my girlfriend asked me to make these for our brunch date and I was shocked how much I loved them. The cinnamon sugar ratio is chef’s kiss, not too sweet so you don’t feel sluggish after eating. Pro tip: warm them up for 10 seconds in the microwave and slather with a little salted butter, *chef’s kiss*
OMG these cinnamon sugar muffins are a total weekday game changer! I made a double batch on Sunday, popped half in the freezer, and they reheat perfectly in 30 seconds in the microwave for quick grab-and-go breakfasts as part of my weekly meal prep. Saves me so much money on stopping for overpriced pastries at the coffee shop! The easy difficulty makes this so doable even when I’m being lazy on meal prep day, and my roommate raved about them too.
