How to Make Healthy Baked Donut
For the donut
Preheat the oven to 350°F (177°C). Grease a donut pan. Set aside.
Whisk the oat flour, baking powder, baking soda, vanilla whey protein powder, and erythritol together in a medium bowl. Set aside.

Whisk the fat-free milk, fat-free Greek yogurt, unsweetened applesauce, egg, and vanilla extract together until fully combined. Pour the wet ingredients into the dry ingredients and stir until well combined.

Pour the batter into a large zip-lock bag. Cut a corner off the bottom of the bag and pipe the batter into each donut mold, filling 2/3 to 3/4 of the way full.


Bake for 9-10 minutes or until the edges are lightly browned. Allow the donuts to completely cool before glazing.
For the glaze
Combine sugar-free vanilla pudding mix and fat-free milk in a small bowl. Whisk until the glaze is smooth. Add fat-free Greek yogurt and food coloring into the mixture and mix until fully combined.
Dunk each donut into the glaze. Transfer each donut to a wire rack over a baking sheet to catch the glaze drippings. Sprinkle with sprinkles.

How to Store This Baked Donut
Keep the donut in an air-tight container and it will last up to 3 – 4 days in the refrigerator. Or freeze the unglazed donuts in an air-tight container for up to 2 months. When you eat, thaw overnight in the refrigerator and warm up to your liking in the microwave.
