Made with vanilla protein powder, oat flour, and a creamy vanilla yogurt glaze, these donuts combine the flavors of a classic birthday cake with the benefits of added protein. They are baked to perfection, topped with colorful sprinkles, and offer a satisfying texture without the guilt of traditional donuts.
Ingredients
For the Donuts:
- 2 scoops (60g) vanilla protein powder
- 1 tablespoon baking powder
- 1/2 teaspoon salt
- 2 tablespoons sprinkles
- 1 1/2 cups oat flour
- 1 egg
- 1 cup vanilla almond milk
- 1/2 cup plain yogurt
- 2 teaspoons cake batter extract
For the Glaze:
- 3/4 cup vanilla yogurt
- 1/2 scoop vanilla protein powder
- 1 teaspoon vanilla almond milk
- Sprinkles, for topping
Instructions
- Preheat the oven: Preheat your oven to 325°F (163°C) to ensure it reaches the correct temperature while you prepare the batter.
- Mix dry ingredients: In a large mixing bowl, combine the vanilla protein powder, baking powder, salt, sprinkles, and oat flour. Whisk thoroughly until well mixed and aerated.
- Add wet ingredients and blend: Add the egg, vanilla almond milk, plain yogurt, and cake batter extract to the dry ingredients. Use a hand mixer on high speed to blend everything together until the batter is smooth and consistent.
- Prepare for baking: Transfer the smooth batter to a piping bag or a large Ziploc bag with the tip cut off to easily pipe the batter into the donut molds.
- Fill the donut pan: Grease a donut pan lightly to prevent sticking. Pipe the batter evenly into the donut molds, filling each about 3/4 full to allow room for rising.
- Bake the donuts: Place the pan in the oven and bake for 12 to 15 minutes, or until a toothpick inserted into a donut comes out clean. Once baked, remove from the oven and let the donuts cool completely in the pan.
- Prepare the glaze: While the donuts cool, whisk together the vanilla yogurt, 1/2 scoop of vanilla protein powder, and 1 teaspoon of vanilla almond milk in a medium bowl. Adjust sweetness if desired by adding a sweetener of choice.
- Glaze and decorate: Dip the tops of the cooled donuts into the prepared glaze, allowing any excess to drip off. Immediately sprinkle extra sprinkles over the glaze for a festive finish. Let the glaze set before serving.
Notes
- Oat flour can be substituted with almond flour for a gluten-free option.
- Ensure the donuts have completely cooled before glazing to prevent the glaze from melting off.
- Use a cake batter extract for authentic birthday cake flavor; vanilla extract can be used if unavailable but flavor will be less pronounced.
- Store glazed donuts in the refrigerator for up to 3 days; reheat slightly before serving if desired.
- These donuts are best enjoyed fresh for optimal texture and flavor.
