Step‑by‑Step Instructions for Blueberry Cake Donuts
Step 1: Prep Blueberries
Start by chopping the dried blueberries into smaller pieces, then place them in a bowl and cover with boiling water. Let them soften for about 5 minutes, during which they’ll plump up nicely. After this, drain the blueberries in a sieve and set aside; these will add bursts of flavor to your Blueberry Cake Donuts.
Step 2: Make Dough
In a large mixing bowl, melt the butter and flip on your mixer to beat it with granulated sugar until the mixture becomes light and fluffy, around 3-4 minutes. Gradually blend in sour cream, egg yolks, and vanilla extract until smooth. Gently fold in the dry mixture of flour, baking powder, and salt, followed by the softened blueberries until just combined to create your luscious donut dough.
Step 3: Chill Dough
Turn the sticky dough onto a lightly floured surface and shape it into a disc about 1 inch thick. Wrap the dough tightly in plastic wrap and refrigerate for at least 1-2 hours, or even up to 24 hours if you prefer. Chilling helps firm up the dough, ensuring your Blueberry Cake Donuts hold their shape while frying.
Step 4: Shape Donuts
Once chilled, roll out the dough on a floured surface until it’s about 1 inch thick. Use a 3-4 inch round cutter to cut out circles and a smaller cutter or a bottle cap to remove the centers for traditional donut shapes. Gather and re-roll scraps as needed, keeping the dough cool to maintain texture.
Step 5: Fry Donuts
Heat a deep skillet or fryer with enough neutral oil to submerge the donuts, aiming for a temperature of 375°F. Carefully lower 2-3 donuts into the hot oil, frying for about 1.5 minutes on each side until they achieve a golden brown hue. Use a slotted spoon to transfer them to a baking rack, allowing any excess oil to drain off.
Step 6: Prepare Glaze
In a small saucepan, heat milk over medium-low heat and whisk in powdered sugar until smooth. Continue stirring until the glaze reaches a pourable consistency, then mix in a splash of vanilla extract. This sweet glaze will complement the flavors of your Blueberry Cake Donuts beautifully.
Step 7: Glaze Donuts
Once the donuts have cooled slightly, dip each one into the glaze, ensuring they’re fully coated. Give them a gentle shake to allow the excess glaze to drip off and place each glazed donut back on the rack. Let them sit until the glaze sets, creating that irresistible sweet finish.

Storage Tips for Blueberry Cake Donuts
Room Temperature: Store your donuts in an airtight container at room temperature for up to 2 days for optimal freshness and taste.
Refrigerator: If you need to keep them a bit longer, you can refrigerate the donuts; however, they may lose some of their delightful texture. Consume within 3 days.
Freezer: For longer storage, freeze the unglazed donuts in a single layer, then transfer to a freezer-safe bag for up to 2 months. Reheat in the oven to regain their golden crispiness.
Reheating: Microwave each donut for a few seconds to warm up; for best results, reheat in the oven at 350°F for 5-7 minutes, allowing you to fully enjoy those homemade Blueberry Cake Donuts.
Make Ahead Options
These Blueberry Cake Donuts are perfect for meal prep, making your busy mornings a breeze! You can prepare the donut dough and refrigerate it up to 24 hours in advance, which helps save precious time. Simply follow the steps to make the dough, wrap it tightly in plastic wrap, and keep it in the refrigerator until you’re ready to fry. Additionally, you can fry the donuts, let them cool, and store them in an airtight container for up to 3 days; just re-glaze them right before serving to ensure they’re just as delicious as when they were fresh. This way, you can enjoy warm blueberry cake donuts any day of the week without the last-minute fuss!

Expert Tips for Blueberry Cake Donuts
• Oil Temperature Check: Ensure your oil is at the right temperature (375°F) to avoid greasy or burnt donuts. Use a thermometer for accuracy.

• First Donut Test: Always fry a small test donut first. This will help you gauge if your oil temperature is correct and if adjustments are needed.
• Cool Before Glazing: Allow donuts to cool slightly before dipping them in glaze. This helps the glaze adhere better for that perfect sweet finish on your Blueberry Cake Donuts.
• Stick to the Chill: Don’t skip the chilling step! Chilling the dough helps maintain its shape during frying and results in a better texture.

Blueberry Cake Donuts Recipe FAQs
What type of blueberries should I use for the donuts?
Absolutely! I recommend using dried blueberries for a concentrated flavor and chewy texture. Fresh blueberries can also be used, but avoid frozen ones as they can alter the dough consistency, making it too wet.
How should I store leftover Blueberry Cake Donuts?
For optimal freshness, store your donuts in an airtight container at room temperature for up to 2 days. If the weather is warm, you can refrigerate them, although they might lose some of their delightful texture—aim to consume them within 3 days.
Can I freeze Blueberry Cake Donuts?
Yes, you can definitely freeze unglazed donuts! Place them in a single layer on a baking sheet until solid, then transfer to a freezer-safe bag for up to 2 months. When ready to enjoy, reheat them in the oven at 350°F for about 5-7 minutes to regain their crispy texture.
What do I do if my donuts turn out greasy?
If your donuts are greasy, it could mean the oil temperature was too low during frying. Make sure your oil is at 375°F before frying. It’s a good idea to test one donut first to ensure the oil is properly heated. Also, avoid overcrowding the pan to allow for even cooking.
Can I use a different type of oil for frying?
Very! You can use various neutral oils like Canola, Vegetable, Peanut, Sunflower, or Avocado. Each oil will impart a slightly different flavor to the donuts, so feel free to choose one that fits your taste preferences.
Are these donuts suitable for people with allergies?
These donuts contain common allergens such as eggs, dairy, and gluten. For those with allergies, you can substitute the eggs with a flaxseed meal or applesauce for binding, use a dairy-free yogurt instead of sour cream, and opt for a gluten-free flour blend for a gluten-free version. Be sure to double-check all ingredient labels!
