How To Make Lemon Blueberry Donuts

• Heat the oven to 425°F and lightly grease two donut pans.
• Whisk together the sugar, melted butter, and oil until the mixture is smooth.
• Add the buttermilk, eggs, vanilla extract, and lemon zest. Whisk again until everything is well blended.
• Stir in the flour, baking powder, salt, and baking soda just until no dry streaks remain.
• Gently fold in the blueberries without overmixing the thick batter.
• Spoon the batter into a piping bag or zip-top bag, then cut a wide opening in one corner.
• Pipe the batter into the donut cavities, filling each one to the top of the indentation.
• Bake for 7 to 8 minutes, or until a toothpick inserted into a donut comes out clean.
• Let the donuts rest in the pans for 10 minutes, then move them to a wire rack to cool completely.
• Mix the powdered sugar with lemon juice, dip the cooled donuts into the glaze, and let them sit on the rack until the glaze sets.

Serving Suggestions

• Serve lemon blueberry donuts with lemon poppy seed muffins for a bright and citrusy breakfast spread.
• Pair them with homemade lemon brownies for a sweet lemon-themed dessert table.
• Add slices of moist lemon bundt cake for an extra-special brunch or celebration.
• Serve them alongside blueberry cake for a delicious blueberry-filled breakfast.
• Pair the donuts with blueberry French toast for a beautiful weekend brunch.
• Add lemon meringue pie for another fresh and flavorful lemon dessert option.

Tips For Success

• Do not overmix the batter after adding the flour. Stir only until the dry ingredients are combined. A few small lumps are perfectly fine. Overmixing can make the donuts dense or tough instead of soft and cakey.
• Expect the batter to be thick. This is normal for baked donut batter. Do not add extra liquid to thin it out. The thick consistency helps the donuts hold their shape and rise properly in the pan.
• Use a piping bag or a large zip-top bag to fill the donut pans. This makes it easier to distribute the thick batter evenly. Cut the opening about ½ to ¾ inch wide. Make sure it is large enough for the blueberries to pass through without getting stuck.
• Fill each donut cavity only to the top of the indentation. The donuts will expand as they bake. Overfilling the pan may cause the batter to rise over the center hole. Evenly filled cavities will also help the donuts bake at the same rate.
• Fold the blueberries into the batter gently. This helps keep the berries whole and prevents the batter from becoming overly mixed. Fresh blueberries work well in this recipe. Frozen blueberries can also be used, but they should be added directly from the freezer so they do not bleed too much color into the batter.
• Check the donuts after 7 minutes of baking. Insert a toothpick into the thickest part of one donut. It should come out clean when the donuts are ready. Avoid baking them longer than necessary, as overbaking can dry them out.
• Let the donuts cool in the pans for 10 minutes before removing them. This gives them time to firm up and makes them easier to lift from the pan. After that, move them to a wire rack so they can cool evenly.
• Wait until the donuts are completely cool before glazing them. Warm donuts will cause the glaze to melt and slide off. Cooled donuts allow the glaze to coat the tops and set properly.
• Add the lemon juice to the powdered sugar gradually. Start with 6 tablespoons, then add more only as needed. The glaze should be smooth enough for dipping but thick enough to stay on the donuts.
• For the best texture, enjoy the donuts the day they are made. When preparing them ahead, bake and cool the donuts before storing them in an airtight container. Add the glaze shortly before serving and give it time to set. Glazed donuts can become softer and stickier when stored in a sealed container.

Variations And Substitutions

• For a stronger lemon flavor, add an extra teaspoon of lemon zest to the donut batter. This will make the citrus taste brighter without changing the texture. You can also make the glaze with freshly squeezed lemon juice. The lemon glaze will taste sweet, tangy, and refreshing.
• For a milder lemon flavor, keep the lemon zest in the batter but replace the lemon juice in the glaze with milk. This creates a simple sweet glaze with less citrus flavor. It is a good option for anyone who prefers a softer lemon taste. Add the milk gradually so the glaze does not become too thin.
• Fresh blueberries work beautifully in these donuts. They add juicy bursts of sweetness throughout the soft lemon batter. Fold them in gently so they stay whole. Avoid stirring the batter more than necessary.
• Frozen blueberries can be used when fresh blueberries are not available. Add them directly from the freezer without thawing them first. Thawed berries can release extra juice and turn the batter purple. Fold the frozen berries into the batter carefully, then pipe it into the pans right away.
• Raspberries can be used instead of blueberries for a tart and fruity variation. Their flavor pairs well with the lemon zest and sweet glaze. Fold them into the thick batter gently. Try to keep the berries from breaking apart while mixing.
• Diced strawberries are another tasty substitution. Cut the strawberries into small pieces so they fit easily into the donut batter and piping bag. Small pieces will also spread more evenly throughout each donut. This version will have a sweet berry flavor with a fresh lemon finish.
• You can adjust the thickness of the glaze by changing the amount of liquid. Start with the smaller amount of lemon juice or milk. Add more one tablespoon at a time until the glaze is smooth enough for dipping. A thicker glaze will stay on top of the donuts, while a thinner glaze will drip farther down the sides.
• You can also leave the donuts unglazed. The lemon zest and blueberries still give them plenty of flavor. Unglazed donuts are easy to store in an airtight container. You can glaze them later, shortly before serving, so the topping stays firm and fresh.

Storage And Reheating

• Lemon Blueberry Donuts are best enjoyed the day they are made, but they can also be prepared ahead of time. For the best results, bake the donuts and let them cool completely before storing them in an airtight container.
• Wait to add the glaze until a few hours before serving. After dipping the donuts, let them sit for at least 20 minutes so the glaze has time to set.
• Once glazed, keep the donuts in a single layer on the counter and leave them uncovered if possible. This helps the glaze stay firm. Storing glazed donuts in an airtight container can make the glaze softer and stickier.
• These donuts do not need to be reheated before serving. Enjoy them at room temperature for the best texture and flavor.
