• Preheat the oven to 350°F.
• Spray a donut pan with nonstick cooking spray; set aside for later.
• In a large mixing bowl, whisk together the flour, sugar, baking powder & salt.
• In a small bowl, whisk together egg, whole milk, butter and vanilla extract.
• Slowly combine the wet ingredients with the dry ingredients and stir together until no flour lumps and all the ingredients are well combined. Don't over-mix the batter or you'll have tough dough.
• Spoon the batter into the donut pan or use a large ziplock bag. Cut a corner off the bottom of the bag and pipe the batter into each donut cavity, filling about ¾ of the way full.
• Bake for 8 -10 minutes or until toothpick inserted into the center of a donut comes out clean.
• Remove from the oven and transfer the donuts onto a wire rack until cool enough to handle but still warm.

Glaze:

• In a medium bowl whisk together the powdered sugar, vanilla and salt.
• Add 1 tablespoon of milk at a time, whisk to combine. If the glaze is too thick, add additional milk, ½ teaspoon at a time until the desired consistency is reached.
• Add food coloring (optional).

Assembly:

• Dip the somewhat warm donuts in the vanilla glaze, return to the wire rack, and immediately top with sprinkles.
• Allow glaze to set at room temperature for about 30 minutes before stacking or serving. Enjoy!
