The batter comes together like a thick, speckled cloud, dotted with juicy blueberries that burst into tiny pockets of jam as they bake. Warm from the oven, each donut wears a glossy lemon vanilla glaze that sets into a delicate sheen, and the first bite lands tender, cakey, and bright with blueberry perfume. Trust me, you’re going to love this, and let me tell you, it’s worth every bite.

Behind the Recipe

These donuts were inspired by the old fashioned cake donuts I grew up loving, the kind that make the kitchen smell like a small bakery. I traded the fryer for a donut pan to keep things light and weeknight friendly, then added a lemon kissed glaze to wake up the blueberries. The result is cozy and nostalgic, but with a fresh, modern lift that makes them disappear fast.

Recipe Origin or Trivia

Cake donuts are cousins to simple butter cakes, using baking powder and sometimes a touch of baking soda for lift rather than yeast. Blueberries stepped into the mix as a natural partner thanks to their jammy sweetness and gentle tartness. Baking them in a donut pan creates that classic ring shape with a soft crumb inside and a lightly golden exterior, perfect for soaking up a thin, crackly glaze.

Chef’s Pro Tips for Perfect Results

Instructions for Making Blueberry Cake Donuts

We will move smoothly from whisk to pan to glaze, keeping the crumb tender and the berries bright. And now, let’s dive to the steps that bring it all together.

Preheat Your Equipment: Heat oven to 350°F, 175°C. Lightly grease two 6 cavity donut pans or spray with baking spray, then set on a sheet pan for easy handling. (Boston Girl Bakes)
Combine Ingredients: In a large bowl whisk 2 cups flour, 3/4 cup sugar, 2 teaspoons baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 1/4 teaspoon nutmeg. In a second bowl whisk 3/4 cup buttermilk, 2 eggs, 1/4 cup melted butter, 1/4 cup neutral oil, and 1 teaspoon vanilla until smooth.
Prepare Your Cooking Vessel: Pour the wet mixture into the dry and whisk just until no dry pockets remain. Pat 1 cup blueberries dry, then gently fold them in with a spatula. The batter should be thick and scoopable. (Southern Living)
Assemble the Dish: Spoon the batter into a piping bag or zip top bag and pipe it into the pans, filling each well about two thirds full for even rings. Smooth the tops lightly if needed.
Cook to Perfection: Bake 10 to 12 minutes, rotating the pans once, until the tops spring back to a light touch and a tester comes out with a few moist crumbs. Cool in the pans 5 minutes, then turn onto a rack. (Boston Girl Bakes)
Finishing Touches: For the glaze, whisk 1 to 1 1/2 cups confectioners’ sugar with 2 to 3 tablespoons lemon juice, 1 to 2 tablespoons milk as needed, and 1 teaspoon lemon zest if using, then dip the warm donuts and let the glaze set on the rack. (Live Well Bake Often)
Serve and Enjoy: Pile the glazed donuts on a platter, add a few extra fresh berries, and enjoy while the glaze is just set and the crumb still slightly warm. Trust me, you’re going to love this.

Texture & Flavor Secrets

The buttermilk and gentle mixing keep the crumb tender and cakey, while the combination of butter and oil means soft richness that lasts. The glaze is intentionally thin so it crackles lightly when you bite, letting lemon brightness and blueberry juiciness share the stage instead of fighting for the spotlight.

Cooking Tips & Tricks

A few friendly nudges will keep your donuts bakery beautiful.

Fill each well evenly for consistent rings and even baking.
If using frozen berries, fold them in last and work quickly to avoid streaking. (Kelly Neil)
Dip twice for a thicker glaze, letting the first coat set before the second. (Live Well Bake Often)

What to Avoid

We are aiming for tender, bright, and neatly glazed, here is how to steer clear of common snags.

Overmixing the batter, which toughens the crumb. Stir just until combined. (Boston Girl Bakes)
Overloading with berries, which can make the rings collapse. Aim for about 1 cup total. (Kelly Neil)
Glazing too hot, which causes sliding. Let donuts cool a few minutes first. (Live Well Bake Often)

Make-Ahead and Storage Tips

Bake and cool the donuts, then store unglazed in an airtight container at room temperature up to 1 day, glaze just before serving. For longer storage, freeze unglazed donuts up to 2 months and thaw at room temperature, then glaze. If needed, refresh for 3 to 4 minutes in a 300°F oven to bring back softness. (Weelicious)

How to Serve Blueberry Cake Donuts

Set the donuts on a wire rack over a sheet pan and dip the tops, letting excess glaze drip for neat edges. Serve with hot coffee or a cool glass of milk, and for a brunch tray, add lemon wedges, fresh berries, and a small bowl of extra glaze for dipping.

Creative Leftover Transformations

Cube a donut and layer with yogurt and berries for a parfait. Pan toast slices in a little butter until golden and serve with fresh blueberries and a spoon of crème fraîche. Or make donut bread pudding by cubing several donuts and baking with a light custard.

Additional Tips

For extra lemon lift, rub the zest into the sugar before mixing to release citrus oils. If you prefer a sweeter crumb, add 2 tablespoons more sugar to the batter. To keep the glaze pristine, place parchment under the rack for easy cleanup.

Make It a Showstopper

Dip donuts twice for a porcelain like glaze, then top with a few microplaned lemon zest sprinkles and a single blueberry on each. Arrange in a spiral on a cake stand so the glossy tops catch the light and promise that first perfect bite.

Variations to Try

Vanilla Bean Glaze: Swap lemon juice for milk and add vanilla bean paste for specks and aroma. (Live Well Bake Often)
Cinnamon Sugar: Skip the glaze and toss warm donuts in cinnamon sugar for a classic finish. (Hostess At Heart)
Almond Blueberry: Add 1/4 teaspoon almond extract to the batter and top with slivered almonds before glazing.
Lemon Poppy: Stir 1 tablespoon poppy seeds into the batter and keep the lemon glaze.
Maple Blueberry: Use a maple glaze by thinning confectioners’ sugar with maple syrup and a splash of milk.
