These soft, tender blueberry cake donuts are packed with juicy fresh blueberries and topped with a glossy blueberry glaze. I first made these on a rainy Saturday morning when Lily wanted to help bake something special, and the smell of warm donuts filling the kitchen made it feel like we had our own little bakery at home. They're surprisingly easy to make with just a donut pan and a few simple ingredients.

Why You'll Love These Blueberry Cake Donuts
Blueberry cake donuts are one of those treats that feel fancy but come together without any fuss. The batter is thick and studded with berries, and the glaze adds just the right amount of sweetness without being too heavy. They're soft, moist, and taste like something you'd grab from a bakery counter, except you made them yourself in your own kitchen.
I love that these homemade blueberry cake donuts don't require yeast or any rising time. You just mix, pipe, and bake. The cardamom is optional, but it adds a subtle warmth that pairs beautifully with the blueberries. My daughter Lily always asks for extra glaze on hers, and honestly, I can't blame her.

blueberry cake donuts Ingredients
Here's a simple list of what goes into making these fluffy baked blueberry cake donuts .
See Recipe Card Below This Post For Ingredient Quantities
For the Donuts:
All-purpose flour: Forms the base of the donut and gives them structure. Spooning and leveling the flour helps you avoid dense donuts.
Baking powder: This is what makes the donuts rise and gives them that soft, cake-like texture.
Salt: Balances the sweetness and brings out the blueberry flavor.
Ground cardamom: This is optional, but it adds a warm, slightly floral note that pairs really well with blueberries.
Fresh blueberries: The star of the recipe. Fresh berries work best here because they hold their shape and burst with flavor as they bake.
All-purpose flour (for tossing): Coating the blueberries in a bit of flour keeps them from sinking to the bottom of the donuts.
Unsalted butter: Adds richness and moisture. Make sure it's melted and slightly cooled before mixing.
Granulated white sugar: Sweetens the batter and helps create a tender crumb.
Eggs: Bind everything together and add moisture. Room temperature eggs mix in more smoothly.
Vanilla extract: Adds a hint of warmth and enhances the overall flavor.
Sour cream: Keeps the donuts moist and gives them a slight tang that balances the sweetness.
Whole milk: Thins the batter just enough to make it pipeable. Room temperature milk blends better with the other ingredients.
For the Blueberry Glaze:
Powdered sugar: Creates the smooth, sweet base of the glaze.
Blueberry jam: Gives the glaze its fruity flavor and a pretty purple tint.
Vanilla extract: Rounds out the flavor of the glaze.
Milk: Thins the glaze to the right consistency. Start with 2 tablespoons and add more if needed.
How to Make Blueberry Cake Donuts
Making these baked blueberry cake donuts is easier than you might think.
Preheat your oven: Set it to 350°F (175°C) and grease your donut pan well so the donuts pop out easily after baking.
Mix the dry ingredients: In a small bowl, whisk together the flour, baking powder, salt, and cardamom if you're using it. This helps distribute the leavening evenly.
Prep the blueberries: Toss them with a tablespoon of flour in a separate small bowl. This little trick keeps them from sinking straight to the bottom as the donuts bake.
Combine the wet ingredients: In a large bowl, whisk together the melted butter, sugar, eggs, vanilla, sour cream, and milk until everything is smooth and well blended.
Bring it together: Add the dry mixture to the wet ingredients and stir gently until just combined. Don't overmix or the donuts can turn out tough.
Fold in the blueberries: Use a rubber spatula to gently fold the flour-coated blueberries into the batter. Be careful not to smash them.
Pipe the batter: Transfer the batter into a piping bag and pipe it into each donut well until they're about three-quarters full. This gives them room to rise without overflowing.
Bake: Pop the pan into the oven and bake for 11 to 12 minutes. The donuts are done when a toothpick inserted into the thickest part comes out clean.
Cool: Let the donuts rest in the pan for about 10 minutes, then carefully transfer them to a wire rack to cool completely before glazing.
Make the glaze: Whisk together the powdered sugar, blueberry jam, vanilla, and 2 tablespoons of milk until smooth. If it's too thick, add a little more milk until it's thin enough to dip.
Glaze the donuts: Dip the top of each cooled donut into the glaze, let any excess drip off, and place them back on the wire rack. Let the glaze set for about 30 minutes before serving.
Substitutions and Variations
You can tweak this blueberry cake donuts recipe to fit what you have on hand.
Buttermilk instead of sour cream: If you don't have sour cream, use buttermilk. It'll give you a similar tangy flavor and tender texture.
Frozen blueberries: You can use frozen blueberries if fresh ones aren't available. Just don't thaw them first, or they'll bleed too much color into the batter.
Skip the cardamom: If you're not a fan of cardamom or don't have any, just leave it out. The blueberry cake donuts will still taste great.
Greek yogurt: Swap the sour cream for plain Greek yogurt for a slightly lighter option.
Lemon zest: Add a teaspoon of lemon zest to the batter for a bright citrus note that pairs beautifully with blueberries.
Different glaze: Try a simple vanilla glaze or even a lemon glaze instead of the blueberry version.
Equipment
Here's what you'll need to make these soft blueberry cake donuts.
Donut pan: This is essential for getting that classic donut shape. A standard 6-cavity pan works perfectly.
Piping bag: Makes filling the donut wells neat and easy. You can also use a large zip-top bag with the corner snipped off.
Wire rack: Lets the blueberry cake donuts cool evenly and gives the glaze a place to drip off.
Mixing bowls: You'll need a few for the dry ingredients, wet ingredients, and glaze.
Whisk: Helps blend everything smoothly, especially the glaze.
Storage and Make-Ahead Tips
These baked blueberry cake donuts are best enjoyed fresh, but you can store them for later.
Room temperature: Keep the blueberry cake donuts in an airtight container at room temperature for up to 2 days. The glaze may soften slightly, but they'll still taste delicious.
Refrigerator: If you want to keep them longer, store them in the fridge for up to 4 days. Let them come to room temperature before serving, or warm them in the microwave for about 10 seconds.
Freezing: You can freeze unglazed donuts for up to 2 months. Wrap them individually in plastic wrap, then place them in a freezer bag. Thaw at room temperature and glaze before serving.
Make-ahead batter: The batter is best used right away, but you can prep your dry and wet ingredients separately the night before and mix them in the morning.
Expert Tips
Here are a few tricks to help you get the best results every time.
Don't overmix the batter: Stir until the dry ingredients are just combined. Overmixing can make the donuts tough instead of tender.
Use room temperature ingredients: Eggs, sour cream, and milk blend more smoothly when they're not cold.
Grease the pan well: Even nonstick pans need a good coating of butter or cooking spray to make sure the donuts release easily.
Check early: Ovens vary, so start checking your donuts at 11 minutes. They're done when the tops spring back lightly when touched.
Let them cool completely before glazing: If you glaze warm donuts, the glaze will just slide off instead of setting nicely.
Add extra berries on top: Before the glaze sets, press a few fresh blueberries onto the top of each donut for a pretty finish.
FAQ
Should you refrigerate blueberry cake donuts ?
You don't have to, but refrigerating them can help them stay fresh longer, especially if your kitchen is warm. Just store them in an airtight container and let them come to room temperature before serving for the best texture.
How long do baked donuts stay fresh?
Baked donuts are best within the first day or two, but they'll stay soft and tasty for up to 4 days if stored properly. Freezing is a great option if you want to keep them longer.
How many minutes to bake doughnuts?
These take about 11 to 12 minutes at 350°F. Keep an eye on them and check with a toothpick to make sure they're cooked through but still moist.
