These blueberry cake donuts are soft, fluffy, and packed with juicy blueberries! They’re a sweet treat that’s perfect for breakfast or dessert.
Baking them at home is super fun, and the smell of fresh donuts is just amazing. I like to top them with a light glaze for that extra sweetness. Enjoying them warm is the best part! 🍩💙
Key Ingredients & Substitutions
All-purpose flour: This is the backbone of the donuts, giving them structure. If you want a lighter texture, consider substituting half of it with cake flour. For gluten-free options, use a gluten-free all-purpose blend.
Buttermilk: It adds moisture and a slight tang, which balances the sweetness. If you don’t have buttermilk, you can make your own by using regular milk mixed with a tablespoon of vinegar or lemon juice, letting it sit for 5-10 minutes.
Blueberries: Fresh blueberries are wonderful, but frozen ones work just as well—just do not thaw them! When using frozen berries, I recommend gently mixing them in to avoid discoloring the batter.
Granulated sugar vs. powdered sugar: Granulated sugar sweetens the dough, and powdered sugar is used for the glaze. For a healthier option, try using coconut sugar for the batter, and a sugar substitute for the glaze.
How Can I Ensure My Donuts Are Tender and Not Overmixed?
Mixing the batter carefully is key to keeping your donuts light and fluffy. Overmixing can develop the gluten in flour, leading to dense donuts. Here are some tips:
- Mix dry ingredients first, then add wet ones to prevent lumps while combining.
- Stir gently with a spatula until just combined. A few lumps are perfectly fine!
- When folding in blueberries, be extra gentle if using frozen ones to avoid color bleeding.
Remember, your goal is a smooth batter without overworking it. Happy cooking!

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 nutmeg (optional, for warm flavor)
- 3/4 cup buttermilk
- 2 large eggs
- 2 tbsp unsalted butter, melted and cooled
- 1 tsp vanilla extract

- Vegetable oil (for frying)
For the Glaze:
- 2 cups powdered sugar
- 3-4 tbsp milk
- 1/2 tsp vanilla extract
How Much Time Will You Need?
This recipe will take about 15 minutes of preparation time and an additional 15-20 minutes for frying, depending on your equipment. Overall, you’ll have delicious blueberry cake donuts ready to enjoy in about 35-40 minutes!
Step-by-Step Instructions:
1. Prepare the Blueberries:
If you’re using fresh blueberries, start by rinsing them under cool water and patting them dry with a paper towel. Set them aside while you prepare the batter.
2. Mix the Dry Ingredients:
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and nutmeg until everything is evenly combined. This gives your donuts a nice rise during frying.
3. Mix the Wet Ingredients:
In another bowl, whisk together the buttermilk, eggs, melted butter, and vanilla extract until they are well blended. This mixture adds moisture and flavor to the donuts.
4. Combine Wet and Dry Ingredients:
Pour the wet mixture into the bowl with the dry ingredients. Gently mix the two together until they are just combined. Be careful not to overmix—the batter should be a little lumpy; this helps keep your donuts tender.
5. Fold in the Blueberries:
Now, carefully fold the blueberries into the batter. If you’re using frozen blueberries, be gentle to avoid turning the batter a blue color. Just mix until the blueberries are evenly distributed.
6. Heat the Oil:
In a deep pot or fryer, pour in enough vegetable oil to reach a depth of about 2-3 inches. Heat the oil to 350°F (175°C). This is the perfect temperature for frying donuts.
7. Shape the Donuts:
If you’re baking the donuts, pipe or scoop the batter into a donut mold pan. If you’re frying, you can pipe the batter onto pieces of parchment paper or drop spoonfuls directly into the hot oil. You can also shape them into rings using your hands.
8. Fry the Donuts:
Carefully place donuts into the hot oil, frying them in batches. Cook each side for about 2-3 minutes, or until they are nicely golden brown. Use a slotted spoon to lift them out and let them drain on paper towels.
9. Prepare the Glaze:
While the donuts are cooling slightly, whisk together the powdered sugar, milk, and vanilla extract in a bowl until smooth. Adjust the amount of milk to reach a thick but pourable glaze consistency.
10. Glaze the Donuts:
While the donuts are still warm (but not too hot), dip the tops into the glaze, letting any excess drip off. Place the glazed donuts on a wire rack to allow the glaze to set.
11. Serve:
Enjoy the blueberry cake donuts fresh! They’re perfect with a warm cup of coffee or tea. These donuts are moist, tender, and bursting with blueberry flavor, topped with a lovely shiny glaze!
Can I Use Whole Wheat Flour Instead of All-Purpose Flour?
Yes, you can substitute whole wheat flour for all-purpose flour! However, the texture of the donuts may become denser. For best results, consider using a mix of whole wheat and all-purpose flour for a lighter texture.
How Should I Store Leftover Donuts?
Store any 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. Reheat them briefly in the microwave or oven before enjoying!
Can I Make These Donuts Vegan?
Absolutely! To make vegan blueberry donuts, substitute the buttermilk with a non-dairy milk mixed with a tablespoon of vinegar or lemon juice. Replace the eggs with a flaxseed meal (1 tbsp ground flaxseed mixed with 3 tbsp water, let it sit for 5 minutes to thicken) or your favorite egg replacer.
What If I Don’t Have a Donut Cutter or Mold?
No worries! You can shape the donuts by using your hands or by using a round cookie cutter to cut out the centers of the donut-shaped batter. Alternatively, drop spoonfuls of batter into the oil and gently shape them into rings with your fingers.
