Prep
- Preheat oven to 350°F. Grease a donut pan thoroughly with butter or nonstick spray, getting into all the crevices.
Make the batter
- In a large bowl, whisk together flour, sugar, baking powder, and salt until well combined.
- In a separate bowl, whisk buttermilk, eggs, melted butter, lemon zest, lemon juice, and vanilla until smooth.
- Pour wet ingredients into dry and stir with a rubber spatula until just combined - do not overmix. Gently fold in flour-dusted blueberries. The batter will be thick.
Fill and bake
- Transfer batter to a piping bag or zip-top bag with the corner snipped. Pipe into donut cavities, filling each about two-thirds full.
- Bake 12-14 minutes until donuts spring back when lightly touched and edges are just golden. Cool in pan 5 minutes, then turn out onto a wire rack to cool completely.
Glaze and finish
- Whisk powdered sugar, lemon juice, and zest until smooth and pourable. Dip the top of each cooled donut into glaze, letting excess drip off. Return to wire rack and let set 15 minutes before serving.
Notes
Tossing blueberries in flour keeps them from sinking to the bottom - do not skip this step. For extra lemon punch, add 1/4 tsp lemon extract to the batter. These are best the day they're made but keep covered at room temperature for up to 2 days; the glaze will soften slightly.
