Easy to make - Lemon Cake Mix Donuts are delicious! Add some lemon zest to these Lemon Cake Mix Donuts just takes them to a whole new level.
Preheat your oven to 350 degrees. Spray your donut pan with non-stick cooking spray.
Add your cake mix and flour to a bowl. Mix to combine.
Add the egg, oil, and water to the bowl and mix to combine.
I scoop my batter into a large Ziploc bag, seal and snip one of the bottom corners off. Slowly pipe the batter into each cavity on the donut pan, filling each cavity 1/2 full.
Place the donut pan in the preheated oven and bake for 14-16 minutes, until the donuts are firm to the touch.
Let them cool in the pan for 5 minutes before moving to a cooling rack to finish cooling.
In a bowl, combine the powdered sugar, melted butter, milk, and lemon juice until smooth.
Once the donuts are completely cooled, dip the top half of the donut into the glaze and immediately sprinkle with lemon zest (if desired).
Repeat until complete.
