Why You’ll Love This Blueberry Cake Donuts
- Bright pop of wild blueberries in every bite for real fruit flavor.
- Quick batter — no chilling, no yeast, bake in about 20 minutes.
- Small batch (6 donuts) so they stay fresh and perfect for family mornings.
- Easy to glaze for a pretty, shareable finish — great for entertaining.
- Freezer-friendly: bake ahead and freeze for fast brunches.
Ingredients Needed :
Batter
- 2 tablespoons butter (plus extra for greasing the donut tin)
- ⅓ cup sugar
- ⅓ cup whole milk
- 1 large egg
- 1 ½ teaspoons vanilla extract
Dry ingredients
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
Fruit
- ¾ cup wild blueberries (plus 2 tablespoons, see recipe notes)
Glaze
- ⅛ teaspoon vanilla extract
- 1 cup powdered sugar (also called icing sugar or confectioners sugar)
Step-by-Step Instructions :
- Preheat the oven to 350ºF (180ºC). Lightly grease a 6-hole donut tin with melted butter and fit a medium-large piping bag with a large round tip. Set aside.
- Add the butter to a large, microwave safe mixing bowl. Heat the butter until melted, about 20 to 30 seconds.
- Add the sugar, milk, egg, and vanilla to the butter. Whisk smooth.
- Use a fine mesh sieve to sift the flour into the bowl. Add the baking powder and salt. Fold gently with a rubber spatula until the flour is mixed in about halfway.
- Add the blueberries. Continue to fold the donut batter gently until the blueberries are evenly distributed, and no dry bits of flour remain. If using frozen blueberries, the batter will probably turn purple.
- Spoon the donut batter into the prepared piping bag. Pipe one full circle of batter neatly into each of the 6 donut holes. Pipe any remaining batter evenly amongst the 6 donuts, then use a wet fingertip to smooth the top of the batter of each donut.
- Place the donut pan in the preheated oven and bake the donuts for 13 to 15 minutes. Remove the pan from the oven and cool the donuts on a wire rack for 10 minutes. Gently turn the donuts out onto the rack to cool completely before glazing.
- To glaze the donuts, heat the blueberries for 15 to 20 seconds in a small microwave safe bowl. Mash the warmed berries with a fork, then press them through a fine mesh strainer. Reserve any juice and discard the solids. Sift the powdered sugar into a second bowl and add the vanilla. Add blueberry juice by the ½ teaspoon, stirring well between each addition, until the glaze is runny, but still quite thick, about the consistency of honey. Spoon the glaze evenly over each cooled donut—there is enough glaze for all 6 donuts. Let the glaze set for at least 20 minutes before serving.
While these bake, you can prep a savory main or sides to balance the sweetness if you’re serving a crowd; a bright herb-chicken dish like Best Ever Blueberry Thyme Chicken pairs nicely on a brunch spread.
Serving Suggestions Blueberry Cake Donuts
Serve warm with a steaming mug of coffee or a pot of tea. These donuts are lovely on a brunch board with yogurt, fresh fruit, and a sliced loaf of Blueberry Cream Cheese Bread for extra indulgence — try adding a piece of Blueberry Cream Cheese Bread for variety. For a playful sweet-savory combo, pair one donut with a gooey Blueberry Grilled Cheese sandwich.
Tips for Success Blueberry Cake Donuts
- Use wild blueberries when possible — they’re smaller and distribute more evenly through the batter.
- If using frozen blueberries, fold them in straight from the freezer to avoid a purple batter and prevent color bleed.
- Don’t overmix after adding flour; fold just until the dry streaks disappear for tender donuts.
- Pipe the batter to get neat, even donut rings and fewer air pockets.
- Cool completely before glazing to keep the glaze smooth and set properly.
- To freeze: flash-freeze cooled donuts on a tray, then transfer to a sealed bag for up to 3 months.
variation (if any)
- Lemon-Blueberry: Add 1 teaspoon lemon zest to the batter and swap half the blueberry glaze juice for fresh lemon juice.
- Cinnamon Sugar: Skip the glaze and brush warm donuts with melted butter, then toss in cinnamon sugar.
- Vanilla Glaze: Omit blueberry juice and whisk 1–2 tablespoons milk into the powdered sugar for a classic vanilla glaze.
FAQs
Q: Can I make these with frozen blueberries?
A: Yes. Fold them in frozen to reduce color bleed. The batter may tint purple, but the flavor is excellent.
Q: How do I store leftover donuts?
A: Store glazed donuts in an airtight container at room temperature for 1–2 days. For longer storage, freeze unglazed donuts and glaze after thawing.
Q: Can I double this recipe?
A: Absolutely. Double all ingredients and bake in multiple pans, or bake in batches. Keep an eye on bake time if using different pans.
Q: Can I use ordinary blueberries instead of wild?
A: Yes — larger garden blueberries work fine but may create slightly larger pockets of fruit in the donuts.
