Method
- Preheat your oven to 350°F (175°C). Lightly grease a standard donut pan or line it with non-stick donut liners. If using a donut pan, a light coating of cooking spray or butter will prevent sticking.
- In a large mixing bowl, whisk together the all-purpose flour, protein powder, granulated sugar (or sweetener), baking powder, ground cinnamon, and salt until thoroughly combined. Ensure there are no lumps of protein powder.1 cup all-purpose flour, 1/2 cup protein powder, 1/2 cup granulated sugar, 2 teaspoons baking powder, 1/2 teaspoon ground cinnamon, 1/4 teaspoon salt
- In a separate medium bowl, whisk together the milk, unsweetened applesauce (or Greek yogurt), large egg, and vanilla extract until smooth and well-emulsified.1/2 cup milk, 1/4 cup unsweetened applesauce, 1 large egg, 1 teaspoon vanilla extract
- Pour the wet ingredients into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix the batter; a few small lumps are perfectly fine. Overmixing can lead to tough donuts.
- Gently fold in the fresh or frozen blueberries into the batter. If using frozen blueberries, you can lightly toss them in a tablespoon of flour before adding them to prevent them from sinking to the bottom of the donuts.1 cup fresh or frozen blueberries
- Spoon or pipe the batter into the prepared donut molds, filling each cavity about two-thirds to three-quarters full. Avoid overfilling, as the donuts will puff up slightly during baking. Piping can make this step neater and more precise.
- Bake for 12-15 minutes, or until a toothpick inserted into the center of a donut comes out clean. The baking time may vary slightly depending on your oven.
- Let the donuts cool in the pan for a few minutes before carefully transferring them to a wire rack to cool completely. This prevents them from sticking and allows them to set properly.
Notes
Store cooled donuts in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze for up to 1-2 months. Reheat gently if desired.
