Ingredients

• 1 ½ cups all-purpose flour
• ½ cup granulated sugar
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ¼ teaspoon salt
• ½ cup extra virgin olive oil
• ½ cup buttermilk (or regular milk with 1 tablespoon lemon juice)
• 2 large eggs
• 1 teaspoon vanilla extract
• Zest of 1 lemon
• ¼ cup fresh lemon juice
• 1 cup fresh or frozen blueberries (do not thaw if frozen)

For the lemon glaze:

• 1 cup powdered sugar
• 2 tablespoons fresh lemon juice
• 1 teaspoon milk (if needed for consistency)

Optional Substitutions

• All-purpose flour: Swap up to half with whole wheat pastry flour for a nuttier taste.
• Sugar: Use coconut sugar or a granulated monk fruit blend for lower sugar.
• Buttermilk: Make sour milk by adding 1 tablespoon lemon juice to ½ cup milk; let sit 5 minutes.
• Olive oil: Use melted coconut oil or avocado oil, but flavor will change.
• Blueberries: Raspberries, chopped strawberries, or diced peaches work well.
• Lemon: Substitute orange zest and juice for a different citrus note.
• Gluten-free: Use a 1:1 gluten-free baking blend; texture may be slightly denser.

Instructions

1. Preheat your oven to 350°F (175°C). Grease a standard 6-cavity donut pan with non-stick spray or brush with olive oil.
2. In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
3. In a separate small bowl or liquid measuring cup, whisk the olive oil, buttermilk, eggs, vanilla extract, lemon zest, and lemon juice together until smooth.
4. Pour the wet ingredients into the dry ingredients and stir with a spatula until just combined. Do not overmix; a few lumps are fine.
5. Gently fold in the blueberries with a spatula, taking care not to crush them. If using frozen blueberries, add them straight from the freezer to avoid bleeding.
6. Spoon the batter into a piping bag or a zip-top bag with the corner snipped off. Pipe the batter evenly into the prepared donut pan, filling each cavity about ⅔ full.
7. Bake for 10-12 minutes, or until the donuts spring back lightly when touched and a toothpick inserted into the thickest part comes out clean.
8. Let the donuts cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before glazing.
9. While the donuts cool, make the glaze: In a small bowl, whisk together powdered sugar and lemon juice until smooth. If too thick, add milk a teaspoon at a time. If too thin, add more powdered sugar.
10. Dip the tops of the cooled donuts into the glaze, letting the excess drip off. Place back on the wire rack and let the glaze set for about 15 minutes. Serve and enjoy!

Pro Tips

• Don't overmix the batter: Overmixing develops gluten and makes donuts tough. Stir until just combined.
• Use frozen blueberries for easier mixing: They hold their shape better and don't bleed as much into the batter.
• Pipe the batter: A piping bag ensures neat, even donuts with less mess.
• Grease the pan well: Even non-stick donut pans may stick; use a good coating of spray or butter.
• Check doneness early: Ovens vary, so start checking at the 10-minute mark.
• Cool completely before glazing: Warm donuts will absorb the glaze and become soggy.
• Add glaze just before serving: Glazed donuts are best eaten the same day for maximum crunch.
• Use high-quality olive oil: A fruity extra virgin olive oil enhances the flavor.

Variations and Substitutions

• Lemon Poppy Seed: Add 1 tablespoon poppy seeds with the dry ingredients for a classic twist.
• Blueberry Streusel: Top donuts with a mixture of 2 tablespoons melted butter, ¼ cup flour, and 2 tablespoons brown sugar before baking.
• Lemon Blueberry Muffin: Bake in a muffin tin for 15-18 minutes; double the recipe for a dozen.
• Cream Cheese Filling: Fit a piping bag with a small tip and inject cream cheese filling after baking.
• Vegan Option: Use flax eggs (2 tablespoons ground flax + 6 tablespoons water), plant-based milk with lemon juice, and organic sugar. Olive oil is already vegan.
• Baked Donut Holes: Use a mini donut pan or drop small spoonfuls onto a parchment-lined baking sheet; bake for 6-8 minutes.

Storage and Reheating

Fridge

Store unglazed donuts in an airtight container at room temperature for up to 2 days. Glazed donuts are best eaten the same day but can be stored in the fridge for 1 day; the glaze may soften.

Freezer

Freeze unglazed donuts in a single layer on a baking sheet until solid, then transfer to a freezer bag. They keep well for up to 3 months. Thaw at room temperature before glazing.

Reheating

Warm donuts in a 300°F oven for 5 minutes or microwave for 10-15 seconds. Glaze after reheating for best texture.

FAQ

Can I use frozen blueberries? Yes, absolutely. Add them frozen to the batter; do not thaw first to prevent discoloration.

Can I make these donuts gluten-free? Yes, use a 1:1 gluten-free baking blend. The texture may be slightly less tender, but still delicious.

Why are my donuts sticking to the pan? Make sure to grease the pan thoroughly, even if it's non-stick. A pastry brush helps get into the crevices.

Can I substitute buttermilk? Yes, make sour milk by adding 1 tablespoon lemon juice to ½ cup milk and letting it sit for 5 minutes.

How do I know when the donuts are done? They should spring back when lightly pressed, and a toothpick inserted into the thickest part should come out clean or with a few moist crumbs.

Can I make these without a donut pan? Yes, use a mini muffin tin and adjust baking time to 8-10 minutes. They'll be like donut holes.

What if my glaze is too thin? Add more powdered sugar, 1 tablespoon at a time, until desired consistency.

How long do these donuts keep? Unglazed, up to 2 days at room temperature. Glazed, best within 24 hours.

Can I double the recipe? Yes, simply double all ingredients. Bake in batches to avoid overcrowding the pan.

Are these donuts dairy-free? If you use a dairy-free milk alternative with lemon juice instead of buttermilk, and skip the glaze or use a dairy-free milk, yes.

What olive oil should I use? A good quality extra virgin olive oil with a fruity, mild flavor works best. Avoid robust or peppery oils.
