These blueberry cake donuts are soft, fluffy, and bursting with sweet blueberry flavor. Just the right treat for breakfast or a snack!
Making these donuts is a breeze – you simply mix, bake, and enjoy! I love adding a light glaze on top; it makes them extra special and oh-so-tempting! 😋
Key Ingredients & Substitutions
All-purpose flour: This is the backbone of the donuts, giving them structure. You can swap it with a gluten-free flour blend if needed, but check that it includes a binding agent like xanthan gum for similar texture.
Sugar: Granulated sugar is perfect for sweetness and texture. If you’re looking for a healthier option, you can use coconut sugar, but it may slightly change the flavor.
Buttermilk: It adds moisture and a little tang. If you don’t have buttermilk, mix 1/2 cup of milk with 1/2 tablespoon of vinegar or lemon juice and let it sit for 5 minutes to mimic the acidity.
Blueberries: Fresh blueberries are delightful, but frozen ones work just as well. Just remember not to thaw them to avoid soggy donuts. You can also try other berries like raspberries or chopped strawberries for variety!
How Do You Ensure Perfectly Tender Donuts?
The key to tender donuts is in the mixing technique. Here’s what to keep in mind:
- Mix the wet and dry ingredients only until just combined. Overmixing will make your donuts tough!
- Folding in the blueberries gently ensures they stay whole and don’t break, which helps keep the donuts fluffy.
- Fill the donut pan only 3/4 full to allow for rising without overflowing.
By following these simple tips, you’ll enjoy soft, delicious blueberry cake donuts that are a hit at any gathering!

How to Make Blueberry Cake Donuts
Ingredients You’ll Need:
For the Donuts:
- 2 cups all-purpose flour
- 3/4 cup granulated sugar
- 2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1/2 tsp ground cinnamon (optional)
- 1/2 cup buttermilk
- 2 large eggs
- 6 tbsp unsalted butter, melted and cooled
- 1 tsp vanilla extract
- 1 cup fresh or frozen blueberries (if frozen, do not thaw)
For the Glaze:
- 1 1/2 cups powdered sugar
- 2-3 tbsp milk
- 1/2 tsp vanilla extract
How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and around 15-18 minutes to bake. Don’t forget to let the donuts cool for a few minutes before adding the glaze! In total, you should allocate about 30-40 minutes to make these delicious treats.
Step-by-Step Instructions:
1. Preheat and Prepare the Pan:
Start by preheating your oven to 350°F (175°C). While the oven heats, grease your donut pan really well with butter or a non-stick spray to ensure the donuts come out easily later.
2. Mix the Dry Ingredients:
In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and cinnamon (if you’re using it). This helps to evenly distribute everything!
3. Combine the Wet Ingredients:
In a separate bowl, whisk together the buttermilk, eggs, melted butter, and vanilla extract until they are nicely mixed. This mixture will add moisture and flavor to the donuts.
4. Combine Wet and Dry Ingredients:
Now, pour the wet ingredients into the dry ingredients. Gently mix until everything is just combined. Remember, overmixing can make the donuts tough, so mix softly!
5. Add the Blueberries:
Carefully fold in the blueberries into the batter. Take your time to avoid breaking them all apart; you want to keep them whole for those delicious bursts of flavor!
6. Fill the Donut Pan:
Spoon the batter into the prepared donut pan, filling each cavity about 3/4 full. This allows enough space for the donuts to rise without overflowing.
7. Bake the Donuts:
Place the donut pan in the preheated oven and bake for 15-18 minutes. To check if they’re done, insert a toothpick into the center of a donut; it should come out clean if they’re baked perfectly!
8. Cool the Donuts:
Once baked, take the pan out of the oven and let the donuts cool in the pan for about 5 minutes. Then, transfer them to a wire rack to cool completely.
9. Make the Glaze:
While the donuts cool, it’s time to prepare the glaze. In a bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. You can adjust the milk to achieve your preferred thickness for the glaze.
10. Glaze the Donuts:
Once the donuts are completely cool, dip the tops into the glaze, allowing any excess to drip off. Place them back on the rack so the glaze can set.
11. Serve and Enjoy!
Now that your blueberry cake donuts are glazed and ready, it’s time to dig in! Serve these delightful treats and enjoy every moist, flavorful bite!
Can I Use Whole Wheat Flour Instead of All-Purpose Flour?
Yes, you can use whole wheat flour for a healthier option, but the texture may be denser. It’s best to use white whole wheat flour as it mimics the texture of all-purpose flour while adding more nutrients.
How Do I Store Leftover Donuts?
Store leftover donuts in an airtight container at room temperature for up to 2 days. For longer storage, place them in the fridge for up to a week. You can also freeze them for up to 3 months; just ensure they are well-wrapped.
What Should I Do If My Donuts Are Sticking to the Pan?
If your donuts are sticking, make sure you greased the pan well before filling. You can also try letting them cool a bit longer in the pan, as they may release more easily once slightly cooled. A gentle run of a knife around the edges can also help release them.
Can I Make These Donuts Without Eggs?
Absolutely! You can replace each egg with 1/4 cup of unsweetened applesauce or 1/4 cup mashed banana. This will help bind the ingredients together while keeping the donuts moist.
