1TBSP Water(+ more if necessary for drizzle consistency)
Preheat your oven to 350F, spray your donut pan with non-stick spray and set aside.
Mix all of the ingredients together until combined.
Fill up your donut pan. Bake at 350F for 10-11 minutes, until your cake tester comes out clean.
Set your pan on a rack and let it cool! Wait at least 25 minutes before taking them out of the pan. (Repeat step 3 and 4 again for another 6 donuts)
For the Glaze: When the donuts have cooled, it's time to make the glaze!
Place a piece of parchment paper underneath the cooling rack. This helps with clean up after you drizzle your glaze.
In a bowl combine the powdered sugar, the juice of 1/2 a lemon and a TBSP of water. Whisk it together until it becomes a thick glaze. If it's too thick, add more water a tsp at a time until it becomes drizzle consistency. It should be the consistency of thick honey, thin enough that it slides off your spoon, but not too thin that it runs off the donut. If you make it slightly too thin you can add a little more sugar.
Using a spoon, drizzle the glaze over the donuts and top with sprinkles.
