Why You’ll Love This Cinnamon Sugar Donut Muffins
- The texture is pure magic: A tender, fluffy crumb on the inside with a slightly crisp, buttery exterior that mimics a freshly fried donut without the fuss of deep-frying.
- One bowl, minimal mess: Everything comes together in a single mixing bowl, which means less washing up and more time spent enjoying the moment.
- That cinnamon sugar coating: Each muffin gets a generous roll in melted butter and a cinnamon-spiked sugar coating, creating a delightful crackle as you bite through it.
- A weekend ritual worth keeping: I make this at least once a week – it’s become a family favourite that signals the start of a relaxed day ahead.
- Incredibly forgiving: Even if you overmix slightly or the oven runs a touch hot, these muffins still turn out beautifully, making them ideal for novice bakers.
Ingredients You’ll Need
- 300g plain flour
- 200g caster sugar
- 2 teaspoons baking powder
- ½ teaspoon bicarbonate of soda
- 1½ teaspoons ground cinnamon
- ½ teaspoon freshly grated nutmeg
- ½ teaspoon fine sea salt
- 240ml buttermilk, room temperature
- 2 large eggs, room temperature
- 80g unsalted butter, melted and slightly cooled
- 2 teaspoons vanilla extract
Tip: If you don’t have buttermilk to hand, stir 2 teaspoons of lemon juice or white vinegar into 240ml of whole milk and let it sit for 5 minutes until it thickens slightly. It works a treat.
For the cinnamon sugar coating:
- 100g caster sugar
- 2 teaspoons ground cinnamon
- 60g unsalted butter, melted
How to Make Cinnamon Sugar Donut Muffins
- Preheat and prepare: Preheat your oven to 190°C (170°C fan) and line a 12-hole muffin tin with paper cases. The kitchen will begin to warm up, and that first hint of heat is a promise of what’s to come.
- Whisk the dry ingredients: In a large mixing bowl, whisk together the plain flour, caster sugar, baking powder, bicarbonate of soda, ground cinnamon, freshly grated nutmeg, and fine sea salt. Watch as the colours meld together — the pale flour against the deep brown of the cinnamon and the speckles of nutmeg — it’s a visual reminder of the flavour waiting to unfold.
- Combine the wet ingredients: In a separate jug or bowl, whisk the buttermilk, eggs, melted butter, and vanilla extract until they are fully combined and look smooth and pale. You’ll smell the vanilla cutting through the richness of the butter — a deeply comforting scent.
- Bring it all together: Pour the wet mixture into the dry ingredients. Using a spatula, fold gently until just combined. A few lumps are absolutely fine — overmixing will make the muffins tough. The batter should be thick, dropping from the spatula in a soft, shaggy ribbon.
- Fill the muffin cases: Divide the batter evenly among the 12 paper cases, filling each about three-quarters full. The batter will look mounded and slightly uneven — that’s exactly how it should be. Tap the tin gently on the counter to settle any air pockets.
- Bake until golden: Place the tin in the preheated oven and bake for 18-20 minutes. At around the 12-minute mark, your kitchen will fill with the unmistakable aroma of cinnamon and toasted butter. The muffins are ready when they are golden brown on top and a skewer inserted into the centre comes out clean. The tops should spring back when lightly pressed.
- Prepare the coating: While the muffins bake, stir together the caster sugar and ground cinnamon for the coating in a shallow bowl. Melt the 60g of butter in a separate small bowl. Set both aside near a wire cooling rack.
- Coat while warm: Allow the muffins to cool in the tin for just 2 minutes — they need to be warm but not too hot to handle. Working with one muffin at a time, brush it all over with the melted butter (or dip it directly if you prefer a more generous coating), then roll it in the cinnamon sugar until every surface is covered. The butter will hiss slightly as it meets the warm muffin, and the sugar will cling in a beautiful, speckled layer. Place on a wire rack to set.
Tips From My Kitchen
- Room temperature ingredients matter more than you think: Cold eggs or buttermilk will seize the melted butter, creating a dense, heavy muffin. Take everything out of the fridge 30 minutes before you begin. The batter will come together more smoothly, and the resulting crumb will be noticeably lighter and more tender.
- Don’t overmix — stop as soon as the flour disappears: The moment you see no more streaks of white flour, put the spatula down. Overworking the gluten develops a rubbery texture, and you’ll lose that soft, cake-like interior. A few lumps in the batter are your friend here; they’ll bake out perfectly in the oven.
- Use freshly grated nutmeg, not pre-ground: This is the single most impactful change you can make. Pre-ground nutmeg loses its volatile oils and tastes flat and dusty. Grating a whole nutmeg directly into the bowl releases a fragrant, almost floral note that lifts the entire flavour profile. The difference is night and day.
- Brush the butter on, don’t dip for a lighter coating: If you prefer a more delicate sugar crust, brush the melted butter onto the warm muffins with a pastry brush. Dipping them directly soaks the muffin more thoroughly, which gives a thicker, crunchier coating. Both methods work, but brushing offers more control and keeps the crumb a little lighter.
- Work in batches when coating: Only take two or three muffins out of the tin at a time to coat. If you leave them all sitting on the rack, they cool too quickly, and the butter won’t spread evenly. The warmth is essential for the sugar to adhere properly, so keep the remaining muffins in the turned-off oven with the door ajar to stay warm while you work.
- Line your muffin tin with paper cases for the best lift: Greasing the tin directly can sometimes cause the edges to brown too quickly, and the muffins may stick. Paper cases provide a gentle barrier that allows the muffins to rise evenly and release effortlessly. The slight crinkle of the paper as you peel it away is part of the pleasure of eating them.
Equipment You’ll Need
- Stand mixer or hand mixer (though a whisk and strong arm work just as well)
- 12-hole muffin tin
- Muffin paper cases
- Large mixing bowl
- Jug or small bowl for wet ingredients
- Whisk and spatula
- Pastry brush (optional, for coating)
- Wire cooling rack
Delicious Variations to Try
- Spiced Orange Version: Add the finely grated zest of one large orange to the dry ingredients, and replace the vanilla extract with 1 teaspoon of orange blossom water. The citrus cuts through the richness beautifully and adds a bright, fragrant lift.
- Vegan Option: Substitute the buttermilk with 240ml of oat milk mixed with 2 teaspoons of lemon juice, use 80g of melted coconut oil instead of butter, and replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, left to sit for 5 minutes). For the coating, use melted coconut oil in place of butter — it sets beautifully and still holds the cinnamon sugar.
- Chocolate Chip Variation: Fold 120g of dark chocolate chips (at least 70% cocoa) into the batter just before spooning it into the cases. The melted pockets of chocolate add a lovely bitterness that balances the sweet cinnamon coating. I like to reserve a handful of chips to press into the tops of the muffins before baking for a more dramatic look.
What to Serve With Cinnamon Sugar Donut Muffins
- A steaming mug of chai tea or a flat white coffee — the spiced notes mirror the cinnamon beautifully.
- A dollop of clotted cream or a spoonful of lemon curd for a tangy contrast.
- Fresh berries, particularly raspberries or sliced strawberries, which cut through the sweetness with their sharp acidity.
- A simple glass of cold milk, if you want to channel the pure nostalgia of a school bake sale.

Frequently Asked Questions
Can I make these ahead of time?
Yes, but they are at their absolute best on the day they are baked. The cinnamon sugar coating will soften overnight as it absorbs moisture from the muffin. If you must make them ahead, store them in an airtight container at room temperature for up to two days, and refresh them in a 150°C oven for 5 minutes before serving to re-crisp the exterior slightly.
Can I freeze Cinnamon Sugar Donut Muffins?
Absolutely. Freeze them without the cinnamon sugar coating, as the coating becomes sticky and claggy after thawing. Bake and cool the muffins completely, then wrap each one individually in cling film and place in a freezer bag for up to three months. When you’re ready to enjoy them, thaw at room temperature, then reheat in a moderate oven, brush with melted butter, and roll in fresh cinnamon sugar.
Why did my muffins come out dense and heavy?
This usually happens for one of two reasons: overmixing the batter or using cold ingredients. Overmixing develops the gluten too much, creating a tough, bready texture rather than a light, tender crumb. Cold butter or eggs can also cause the batter to seize. Next time, mix until just combined and ensure all your ingredients are at room temperature before you start.
Can I use a different type of flour?
Plain flour works best for this recipe because it provides the right structure for a soft, cake-like crumb. You could substitute up to half of the plain flour with wholemeal spelt flour for a nuttier flavour, but the muffins will be denser and slightly less fluffy. Avoid using self-raising flour unless you adjust the baking powder, as the muffins may rise too much and then collapse.
How do I get an even cinnamon sugar coating?
The key is to coat the muffins while they are still very warm but not piping hot. Work in small batches, taking only two or three muffins out of the tin at a time. Use a pastry brush to apply an even, thin layer of melted butter all over the surface, then roll the muffin in the cinnamon sugar mixture, pressing gently to help it adhere. A shallow, wide bowl makes this much easier than a deep one.
