Light and refreshing, these easy baked lemon donuts are filled with flavor and surprisingly easy to make. They make a perfect breakfast or brunch item, or make a batch of mini donuts to serve to a crowd at a potluck.
Preheat oven to 375 degrees, and grease donut pans
Add flour, sugar, baking powder, salt, and lemon zest to a bowl and stir.
2 cups flour, 1/2 cup sugar, 1 teaspoon baking powder, 1/4 teaspoon salt, zest of one lemon
In a separate bowl, whisk together milk, lemon juice, mayonnaise, butter, eggs, and vanilla. Beat until well incorporated and frothy. Add liquid ingredients to dry ingredients and stir until just combined.
1/2 cup milk, 1/4 cup lemon juice, 1/4 cup mayonnaise, 3 tablespoons unsalted butter, 2 eggs, 2 teaspoons vanilla
Scoop batter into a gallon-size zip top bag and seal. Snip off a small section from the corner. Add batter to donut pans, filling to no more than 2/3 full.
Bake at 375 degrees for 7-9 minutes, until donut springs back when you gently press it. Cool in pans for 2 minutes, then turn out onto a wire rack to finish cooling.
Mix the glaze while donuts are cooling. Add powdered sugar, lemon zest, and remaining quarter cup of lemon juice to a bowl and stir together with a fork.
1 1/4 cups powdered sugar, zest of one lemon, 1/4 cup lemon juice
Dip cooled donuts into the glaze, twisting as you lift, then shake off excess. Return donut to cooling rack for the glaze to harden.
Enjoy immediately or store in an airtight container on the counter for up to 2 days.
