Description

These baked protein donuts are soft, fluffy, and packed with protein. Made with whey protein powder and simple ingredients, this easy protein donut recipe can be baked in the oven or air fryer for a quick high-protein breakfast or snack. Each serving has 15 g of protein, and the donuts are perfect for meal prep.


Ingredients

Units Scale
  • 1 1/2 cups self-raising flour
  • 1/2 cup vanilla whey protein powder
  • 1 1/2 cups milk, any type
  • 2 eggs
  • 2 tablespoons melted butter

For the Cinnamon Sugar Coating

  • Olive oil spray
  • 2 tablespoons sugar
  • 1 teaspoon ground cinnamon

Instructions

Step 1: Mix the Dry Ingredients

  1. In a large mixing bowl, whisk together the self-raising flour and vanilla whey protein powder until evenly combined.

Step 2: Add the Wet Ingredients

  1. Make a well in the center of the dry ingredients and add the milk, eggs, and melted butter. Mix until a smooth batter forms. Do not overmix, as this can make the protein donuts dense.
  2. Step 3: Prepare the Donut Pan
  3. Lightly spray the donut pan with olive oil spray to prevent sticking. Pour the batter evenly into the donut molds.

Step 4: Bake or Air Fry

Oven Method

  1. Bake at 180°C (350°F) for 18–20 minutes or until just cooked through.

Air Fryer Method

  1. Air fry at 180°C (350°F) for about 20 minutes, or until the protein donuts are lightly golden and cooked through in the center.

Step 5: Add the Cinnamon Sugar Coating

  1. Remove the donuts from the pan and lightly spray them with olive oil spray. Dip each donut into the cinnamon sugar mixture while still warm.

Notes

Don't overbake the protein donuts, as protein powder can make them dry out quickly.

Use room-temperature eggs and milk for a smoother batter.

Vanilla whey protein powder gives the softest texture.

Fill the donut molds about ¾ full.

For the cinnamon sugar coating, lightly spray the warm donuts with olive oil spray before coating.
