How to Make Blueberry Lemon Curd Donut Holes Recipe

Step 1: Prepare the Lemon Curd

Start by melting the butter in a microwave-safe bowl. Then whisk together the lemon juice, beaten eggs, sugar, and lemon zest until well combined. To cook, microwave the mixture in short intervals—1 minute, then 30 seconds—whisking thoroughly in between. Repeat this process several times until the lemon curd thickens enough to coat the back of a spoon with a custard-like consistency. Once done, cool it down completely and refrigerate until you need it later. This homemade lemon curd is the heart and soul of the filling, offering that perfect tangy burst inside each donut hole.

Step 2: Make the Blueberry Cake Donut Dough

In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. In another bowl, combine the buttermilk, egg, Greek yogurt (or sour cream), melted butter, and vanilla extract until smooth and well incorporated. Gently fold the wet ingredients into the dry ingredients, being careful not to overmix to keep the donuts tender. Finally, fold in the blueberries, ensuring they’re evenly distributed without breaking them up too much. This batter will yield fluffy, flavorful donut holes that are bursting with fruit goodness.

Step 3: Fry the Donut Holes

Heat avocado oil in a deep pot or fryer to 350°F (175°C). Using a small cookie scoop or spoon, carefully drop dollops of the batter into the hot oil, frying in batches to avoid overcrowding. Fry for about 2-3 minutes, turning occasionally until the donut holes are golden brown and cooked through. Remove them with a slotted spoon and place on a paper towel-lined plate to drain excess oil. Frying at the right temperature ensures crispy exteriors and pillowy interiors.

Step 4: Fill the Donut Holes with Lemon Curd

Once the donut holes have cooled just enough to handle, use a small piping bag or a squeeze bottle with a narrow tip to inject the chilled lemon curd into each donut. You'll get that wonderful surprise of tangy filling as soon as you bite in, making these treats extra special.

Step 5: Prepare and Apply the Vanilla Bean Buttermilk Glaze

Whisk the powdered sugar with 2 tablespoons of cultured buttermilk and vanilla until smooth, adding more buttermilk as needed to achieve a pourable glaze consistency. Dip each filled donut hole halfway into the glaze or drizzle it on top. The glaze adds a touch of sweetness and a silky texture that beautifully complements the bright lemon curd and fruity blueberries.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

If you have leftovers, keep them in an airtight container at room temperature for up to 2 days. Because they’re best enjoyed fresh and warm, they might lose some crispness over time but will still taste delicious.

Freezing

You can freeze unfrosted donut holes by placing them in a single layer on a baking sheet and freezing until solid, then transferring them to a freezer-safe container or bag. Frozen donut holes last up to 1 month and can be thawed overnight in the fridge before reheating and glazing.

Reheating

Reheat donut holes gently in a 325°F (160°C) oven for about 5-7 minutes to bring back their crisp exterior and softness inside. Once warm, fill and glaze them as usual for a fresh-baked experience even the next day.

FAQs

Can I use frozen blueberries for this Blueberry Lemon Curd Donut Holes Recipe?

Absolutely! Frozen blueberries work great and can be folded into the batter directly from frozen. Just be gentle when mixing to avoid staining the dough too much.

Is there a way to make these donut holes without frying?

If you prefer a baked version, you can spoon the batter into a mini muffin tin and bake at 350°F (175°C) for about 12-15 minutes. They won’t have the same crispy exterior but will still be moist and delicious.

How long does the lemon curd filling keep?

Homemade lemon curd can be stored in the refrigerator for up to one week when kept in a clean, sealed container.

Can I prepare the dough in advance?

Yes, you can prepare the batter and keep it in the refrigerator for up to 24 hours before frying. Just bring it to room temperature and stir gently before frying.

What can I substitute for cultured buttermilk in the glaze?

If you don’t have cultured buttermilk, you can use regular milk with a splash of lemon juice or vinegar as a quick substitute to maintain that tanginess and texture in the glaze.
