Preheat the oven to 350℉. Spray two donut pans with baking spray. Set aside.
02 -
In a medium bowl, mix the flour, baking powder, baking soda, salt, and sugar.
03 -
In a separate bowl, mix the eggs, milk, sour cream, melted butter, vanilla extract, lemon zest, and lemon juice. Add the wet ingredients into the dry ingredients and mix until just combined.

Use a piping bag to pipe the batter into the donut pan. It is really easy to over fill the pan. It should only be half full.
05 -
Bake for 9-11 minutes until a toothpick inserted comes out clean. If your oven has room, you can bake both at the same time.
06 -
Let the donuts sit in the hot pan for 10 minutes before transferring to a cooling rack. Cool completely before icing.
07 -
In a small bowl, mix the powdered sugar, lemon zest, lemon juice, and milk. Use a whisk to mix until smooth. It needs to be runny enough to drip off the donuts, but not too runny that the batter is translucent.

Dip the donuts into the icing. Top with extra lemon zest. Let the icing set before digging in.
