You know those evenings when the clock strikes six, the kids are circling the kitchen like hungry sharks, and you’ve got absolutely nothing planned? That’s exactly when I pull out my donut pan.

Why You’ll Love These Baked Blueberry Cake Donuts

• No deep-frying required: You skip the messy, smelly oil entirely. These donuts bake up golden and tender straight from the oven, with zero splatter to clean off the hob.
• One-bowl mixing: Everything comes together in a single bowl, so your sink stays almost empty. My kids absolutely devour this every time I make it, and I love that I’m not scrubbing pans for twenty minutes afterward.
• Make-ahead friendly: You can prep the dry ingredients the night before, or bake the full batch and reheat them for breakfast. They keep beautifully in an airtight container for two days.
• Fresh blueberries in every bite: Those little bursts of juicy fruit make these feel like a proper treat, yet they’re wholesome enough to serve as a quick dinner dessert or even a grab-and-go breakfast.
• Kid-approved warmth: The soft, cakey texture and gentle sweetness win over even the pickiest eaters. My youngest once asked if we could have “donut dinner” every night—and honestly, I almost agreed.

Ingredients You’ll Need

• 200g plain flour
• 100g caster sugar
• 1½ teaspoons baking powder
• ½ teaspoon bicarbonate of soda
• ½ teaspoon ground cinnamon
• ¼ teaspoon salt
• 120ml buttermilk (or 120ml milk mixed with 1 tablespoon lemon juice, left for 5 minutes)
• 1 large egg
• 60g unsalted butter, melted and slightly cooled
• 1 teaspoon vanilla extract
• 150g fresh blueberries (if using frozen, do not thaw)
• 1 tablespoon plain flour (for coating the blueberries)

Tip: Coating the blueberries in that extra tablespoon of flour before folding them into the batter prevents them from sinking to the bottom of the donuts. Every single donut will have berries distributed evenly from top to bottom.

How to Make Baked Blueberry Cake Donuts

1. Preheat the oven to 180°C (fan 160°C) and grease your donut pan generously. Use a pastry brush to coat each cavity with melted butter or a neutral oil. The pan should look glossy but not pooled. This step ensures your donuts release cleanly with that perfect golden edge.
2. Whisk the dry ingredients together in a large mixing bowl. Combine the flour, caster sugar, baking powder, bicarbonate of soda, cinnamon, and salt. Whisk until the mixture is uniform and pale beige in colour, with no streaks of baking powder visible. The cinnamon will smell warm and slightly sweet as you work.
3. In a separate jug, whisk the wet ingredients. Beat the buttermilk, egg, melted butter, and vanilla extract together until the egg is fully incorporated and the mixture looks pale yellow and slightly frothy on top. The butter should be cool enough that it doesn’t scramble the egg—test a drop on your wrist; it should feel just warm, not hot.
4. Pour the wet mixture into the dry ingredients and stir gently. Use a rubber spatula and fold just until the flour disappears. The batter will look thick, lumpy, and slightly shaggy—that’s exactly right. Stop mixing the moment you no longer see white flour. Overmixing will make the donuts tough and dense.
5. Toss the blueberries with the reserved tablespoon of flour, then fold them into the batter. Gently turn the berries into the mixture using only three or four folds. You want the blueberries scattered throughout, but the batter should still be thick and slightly sticky. A few purple streaks are fine; they’ll bake out.
6. Spoon the batter into the prepared donut pan. Fill each cavity about three-quarters full—the batter will spread and rise as it bakes. A piping bag makes this step incredibly neat, but two spoons work just as well. The surface should look bumpy from the berries peeking through.
7. Bake for 10 to 12 minutes, or until the donuts are golden brown. The tops will spring back when you press them lightly with your finger, and a skewer inserted into the thickest part should come out with just a few moist crumbs attached. The kitchen will smell like a bakery—warm butter, vanilla, and fruity sweetness.
8. Let the donuts cool in the pan for 3 minutes, then transfer them to a wire rack. Run a small offset spatula or butter knife around the edges if they feel stuck. The donuts should lift out easily, revealing a deeply golden ring with tiny dark blueberry flecks. Let them cool completely if you plan to glaze them, or serve them warm as they are.

Tips From My Kitchen

• Don’t skip greasing the pan—even non-stick pans need it. Baked donuts have a higher sugar content than muffins, which makes them prone to sticking. I use a pastry brush with melted butter and get into every crevice. The first time I made these, I skipped this step and ended up with torn, crumbly donuts. Never again.
• Use a piping bag for even filling. A large zip-top bag with the corner snipped off works perfectly. It lets you control the flow and keeps the batter from spilling over the edges of the pan. Clean, uniform donuts every single time.
• If using frozen blueberries, keep them frozen until the very last second. Thawed berries release too much liquid into the batter, turning your donuts a muddy grey-blue colour and making the texture soggy. Frozen berries also hold their shape better during baking.
• Make the batter ahead for a faster weeknight dinner. Measure all your dry ingredients into a bowl, cover it, and leave it on the counter. Measure the wet ingredients into a jug and refrigerate them. When you’re ready to eat, simply combine, fold in the berries, and bake. Dinner on the table in fifteen minutes flat.
• Don’t overfill the cavities. Three-quarters full is the sweet spot. Any more and the donuts will puff up and lose their hole, turning into muffin tops. Any less and you’ll get flat, sad little rings. The batter should sit just below the rim of each cavity.
• Cool them properly before adding any glaze. A warm donut will absorb a glaze like a sponge, turning it sticky and wet instead of forming that lovely crackly shell. Five minutes on the wire rack is usually enough. You’ll see the surface become slightly dry to the touch.

Equipment You’ll Need

• Stand mixer or hand mixer (though a whisk works too)
• Baking tray (to catch any drips under the donut pan)
• Parchment paper (if you want to line the tray for easy cleanup)
• Wire cooling rack
• Donut pan (standard 6- or 8-cavity)
• Large mixing bowl
• Rubber spatula
• Pastry brush or paper towel for greasing

Delicious Variations to Try

• Lemon Blueberry Version: Add the finely grated zest of one lemon to the dry ingredients, and replace the vanilla extract with 1 tablespoon of fresh lemon juice. The citrus brightens the blueberries beautifully and adds a fresh, zingy note that cuts through the buttery richness.
• Vegan Option: Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, left for 5 minutes until thick and gel-like). Use a plant-based milk mixed with lemon juice for the buttermilk, and swap the butter for melted coconut oil or a neutral vegan butter. The texture stays tender and soft.
• Gluten-Free Alternative: Substitute the plain flour with a good-quality 1:1 gluten-free baking blend that contains xanthan gum. Add an extra tablespoon of milk to the batter, as gluten-free flours tend to absorb more liquid. The donuts will be slightly more crumbly but equally delicious.

What to Serve With Baked Blueberry Cake Donuts

• A glass of cold milk for dipping—my kids swear by this ritual
• A small bowl of Greek yogurt mixed with a drizzle of honey for a protein boost
• Fresh fruit salad on the side, especially if you’re serving these as a light dinner dessert
• A warm cup of tea or coffee for the grown-ups while the little ones race through their donuts
