Ingredients You’ll Need
- 250g plain flour
- 150g caster sugar
- 2 teaspoons baking powder
- ½ teaspoon bicarbonate of soda
- ½ teaspoon fine sea salt
- 1 teaspoon ground cinnamon (for the batter)
- 120ml buttermilk (room temperature)
- 80ml whole milk (room temperature)
- 1 large egg (room temperature)
- 60g unsalted butter, melted and slightly cooled
- 1 teaspoon vanilla extract
Tip: For the coating, you will need an additional 100g caster sugar and 2 tablespoons ground cinnamon. Using a fine-mesh sieve to dust the cinnamon-sugar over the muffins will create an even, professional-looking layer.
How to Make Cinnamon Sugar Donut Muffins
- Preheat and prepare: Position a rack in the centre of your oven and preheat to 180°C (fan-assisted). Grease a 12-hole muffin tin with butter or line with paper cases. The tin should feel warmly hot when you hold your hand near it.
- Whisk the dry ingredients: In a large bowl, sift together the flour, caster sugar, baking powder, bicarbonate of soda, salt, and 1 teaspoon of cinnamon. Whisk until they are evenly combined; the mixture will look pale and smell faintly sweet.
- Combine the wet ingredients: In a separate jug, whisk together the buttermilk, whole milk, egg, melted butter, and vanilla extract. The mixture will be a smooth, pale yellow liquid with a slightly thick consistency from the buttermilk.
- Mix gently: Pour the wet ingredients into the dry ingredients. Using a rubber spatula, fold together with as few strokes as possible. Stop as soon as you see no more streaks of flour—the batter will look lumpy and slightly shaggy. Over-mixing here will make the muffins tough.
- Fill the tin: Divide the batter evenly among the 12 muffin cups, filling each about three-quarters full. The batter should be thick and mounded slightly in the centre. Tap the tin once on the counter to settle any air pockets.
- Bake until golden: Bake for 12–14 minutes. The muffins will be domed, golden brown on top, and a skewer inserted into the centre should come out clean. The kitchen will smell like warm cinnamon and toasted butter.
- Cool and coat: Let the muffins cool in the tin for 5 minutes. Meanwhile, mix the remaining 100g caster sugar and 2 tablespoons cinnamon in a shallow bowl. While the muffins are still warm (but not scorching hot), brush each one lightly with melted butter, then roll it in the cinnamon sugar until completely coated. The sugar will stick and create a crackly, glossy crust.
Tips From My Kitchen
- Room temperature ingredients are key: When buttermilk, milk, and egg are cold, they seize the melted butter, creating a dense muffin. Let everything sit out for 20 minutes before starting; you’ll feel the batter come together more smoothly.
- Don’t skip the buttermilk: The acidity in buttermilk reacts with the bicarbonate of soda to give a tender, airy crumb. If you don’t have buttermilk, add 1 tablespoon of lemon juice to 120ml of milk and let it stand for 5 minutes until it curdles slightly.
- Use a pastry brush for the coating butter: Dipping the warm muffin directly into melted butter can make it soggy. Instead, brush a thin, even layer on all sides—this ensures the sugar adheres without soaking the crust.
- Double-coat for a thicker shell: After the first rolling, let the muffins sit for 2 minutes, then brush with a second light layer of butter and roll again. This creates a professional, crunchy exterior that won’t flake off after a few hours.
- Bake in the centre of the oven: Placing the tin too close to the top or bottom element will cause uneven browning. The centre rack ensures the muffins rise evenly and develop a uniform golden colour.
Common Mistakes to Avoid
- Overcrowding the pan: Filling the muffin cups more than three-quarters full will cause the batter to spill over the edges as it rises, creating flat, misshapen muffins. Stick to the recommended fill level for those perfect, domed tops.
- Wrong temperature: Baking at a lower temperature will result in pale, dense muffins that lack the signature golden crust. Always preheat your oven fully and use an oven thermometer if needed—180°C is the sweet spot for this recipe.
- Skipping the rest time: Letting the muffins cool for exactly 5 minutes in the tin is crucial. If you remove them too soon, they will crumble; if you wait too long, the steam will make the bottoms soggy. That 5-minute window gives you the perfect texture for coating.
Delicious Variations to Try
- Spicy Version: Add ½ teaspoon of cayenne pepper to the cinnamon-sugar coating for a warm, gentle heat that surprises the palate. The spice cuts through the sweetness beautifully, especially when served with a cold glass of milk.
- Vegetarian/Vegan Option: Substitute the buttermilk with 120ml of oat milk mixed with 1 tablespoon of apple cider vinegar, and replace the egg with a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water). Use a plant-based butter for the coating—the texture remains remarkably tender.
- Different Protein: Fold 60g of finely chopped toasted pecans or walnuts into the dry ingredients before adding the wet mix. The nuts add a toasty, savoury crunch that contrasts with the soft, sugary exterior.
What to Serve With Cinnamon Sugar Donut Muffins
- A small pot of warm, salted caramel sauce for dipping
- Fresh berries (raspberries or sliced strawberries) to cut through the sweetness
- A dollop of clotted cream or crème fraîche for a tangy contrast
- A glass of iced Lavender Lemonade for a refreshing pairing

Frequently Asked Questions
Can I make these Cinnamon Sugar Donut Muffins ahead of time?
Yes, you can bake them a day in advance, but store them uncoated in an airtight container at room temperature. On the day you serve them, reheat the muffins in a 160°C oven for 5 minutes, then brush with butter and roll in cinnamon sugar while warm. This restores the fresh-from-the-oven texture and ensures the coating stays crisp.
Why did my muffins turn out dense and heavy?
The most common culprit is over-mixing the batter. Once the wet and dry ingredients meet, gluten develops quickly; mixing until just combined—with a few lumps still visible—keeps the crumb light and airy. Another factor could be using cold ingredients, which prevent the butter from emulsifying properly.
Can I freeze these donut muffins?
Absolutely. Freeze them uncoated in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 3 months. When you’re ready to serve, thaw at room temperature, reheat briefly in the oven, and coat with butter and cinnamon sugar. The coating is best applied fresh, as frozen sugar can become sticky.
How do I get the sugar coating to stick evenly?
The secret is twofold: the muffins must be warm but not hot, and you should use a pastry brush to apply a thin, even layer of melted butter. If the muffin is too hot, the butter will soak in and the sugar will slide off; if too cool, the butter will solidify and the sugar won’t adhere. The 5-minute cooling rest is your sweet spot.
Can I use paper liners for the muffins?
Yes, paper liners work well and make cleanup easier, but they will prevent the outer crust from forming directly against the tin. If you prefer a more authentic donut-like texture, grease the tin generously with butter and skip the liners—you’ll get a slightly firmer, golden-brown exterior that mimics a fried donut.
