Air Fryer Protein Donuts – Light, Fluffy, and Ready Fast

Air Fryer Protein Donuts bring together the best of both worlds: a comfort-food classic with a boost of protein and far less oil. They’re quick to mix, fast to cook, and surprisingly satisfying for a snack or post-workout treat. No yeast, no deep frying, no long wait times—just tender, donut-shaped goodness you can make on a busy morning.
If you’ve got a donut pan that fits your air fryer and a scoop of protein powder, you’re already halfway there. Let’s keep it simple, delicious, and practical.
Air Fryer Protein Donuts - Light, Fluffy, and Ready Fast
Ingredients
- 1 cup (120 g) oat flour or all-purpose flour
- 1/2 cup (45–50 g) vanilla protein powder (whey or plant-based)
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp fine salt
- 1/3 cup (65 g) granulated sugar or coconut sugar
- 1 tsp ground cinnamon (optional)
- 2 large eggs, room temperature
- 1/2 cup (120 ml) unsweetened milk of choice (dairy or non-dairy)
- 1/3 cup (80 g) plain Greek yogurt or thick non-dairy yogurt
- 2 tbsp neutral oil (avocado, canola) or melted coconut oil
- 2 tsp vanilla extract
- Nonstick spray or a little oil for the donut pan
Instructions
- Preheat and prep: Preheat your air fryer to 320°F (160°C) if your model allows it. Lightly grease a silicone or metal donut pan that fits in your basket.
- Mix dry ingredients: In a bowl, whisk flour, protein powder, baking powder, baking soda, salt, sugar, and cinnamon (if using) until no clumps remain.
- Mix wet ingredients: In another bowl, whisk eggs, milk, yogurt, oil, and vanilla until smooth.
- Combine: Pour wet into dry and fold gently until just combined. The batter should be thick but spoonable. If it’s too thick, add 1–2 tsp milk at a time. Avoid overmixing.
- Fill the pan: Spoon or pipe batter into the donut wells, filling each about 3/4 full. Smooth the tops with a damp spoon for even rising.
- Air fry: Place the pan in the air fryer basket. Cook at 320°F (160°C) for 8–10 minutes, or until the donuts are set, spring back to a light touch, and a toothpick comes out clean.
- Cool: Let donuts rest in the pan for 3 minutes, then transfer to a rack to cool. This helps them firm up and stay tender.
- Glaze (optional): Whisk glaze ingredients until smooth. Dip the cooled donuts, let the excess drip off, and set on a rack. For a lighter touch, drizzle instead of dipping.
- Serve: Enjoy slightly warm or at room temperature. They’re great plain, too.
What Makes This Special

- High protein, lower guilt: Each donut packs extra protein without relying on heavy oils or deep frying.
- Fast cooking time: Thanks to the air fryer, they’re done in about 8–10 minutes per batch.
- Familiar flavors: Soft and cake-like, with the option to go classic vanilla, chocolate, or cinnamon.
- Flexible ingredients: Works with whey or plant-based protein, plus gluten-free flour if you need it.
- Easy to customize: Top with a light glaze, melted chocolate, or a dusting of cinnamon-cocoa.
What You’ll Need
- 1 cup (120 g) oat flour or all-purpose flour
- 1/2 cup (45–50 g) vanilla protein powder (whey or plant-based)
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp fine salt
- 1/3 cup (65 g) granulated sugar or coconut sugar
- 1 tsp ground cinnamon (optional)

Optional Glaze: 1/2 cup powdered sugar, 1–2 tbsp milk, 1/2 tsp vanilla extract, pinch of salt. For a chocolate glaze, add 1 tbsp cocoa powder.
Instructions
- Preheat and prep: Preheat your air fryer to 320°F (160°C) if your model allows it.
Lightly grease a silicone or metal donut pan that fits in your basket.
- Mix dry ingredients: In a bowl, whisk flour, protein powder, baking powder, baking soda, salt, sugar, and cinnamon (if using) until no clumps remain.
- Mix wet ingredients: In another bowl, whisk eggs, milk, yogurt, oil, and vanilla until smooth.
- Combine: Pour wet into dry and fold gently until just combined. The batter should be thick but spoonable. If it’s too thick, add 1–2 tsp milk at a time.
Avoid overmixing.
- Fill the pan: Spoon or pipe batter into the donut wells, filling each about 3/4 full. Smooth the tops with a damp spoon for even rising.
- Air fry: Place the pan in the air fryer basket. Cook at 320°F (160°C) for 8–10 minutes, or until the donuts are set, spring back to a light touch, and a toothpick comes out clean.
- Cool: Let donuts rest in the pan for 3 minutes, then transfer to a rack to cool.
This helps them firm up and stay tender.
- Glaze (optional): Whisk glaze ingredients until smooth. Dip the cooled donuts, let the excess drip off, and set on a rack. For a lighter touch, drizzle instead of dipping.
- Serve: Enjoy slightly warm or at room temperature.
They’re great plain, too.
Batch note: If your air fryer is small, cook in batches and keep finished donuts loosely tented with foil to prevent drying.
Storage Instructions
- Room temperature: Store in an airtight container for up to 24 hours.
- Refrigerate: Keep for 3–4 days. Warm in the air fryer at 300°F (150°C) for 2–3 minutes to refresh.
- Freeze: Freeze unglazed donuts for up to 2 months. Thaw at room temperature or reheat from frozen at 300°F (150°C) for 5–6 minutes.
- Glaze later: If you plan to store, glaze just before serving to keep the texture fresh.

Health Benefits
- More protein per bite: Helps with satiety and muscle repair, especially after workouts.
- Less oil than frying: Air frying reduces added fats while keeping a tender crumb.
- Balanced carbs: Oat flour adds fiber and a steadier energy release than refined flour alone.
- Customizable sugars: Using coconut sugar or a lower-sugar glaze can keep overall sugar in check.
- Better portion control: Individual donuts make it easier to track macros compared to a large cake.
What Not to Do
- Don’t overmix: Overworking the batter can make the donuts dense and rubbery, especially with protein powder.
- Don’t overfill the pan: Going past 3/4 full can cause spillover and uneven cooking.
- Don’t crank the heat too high: High temps brown the outside before the center sets.
Stick near 320°F (160°C).
- Don’t skip cooling: Letting them rest helps the structure set and prevents soggy bottoms.
- Don’t glaze while hot: Warm donuts will melt the glaze and make it run off.
Alternatives
- Protein powder swaps: Use chocolate or unflavored protein. For plant-based options, pea or a pea-rice blend works well. You may need 1–2 tbsp extra milk for thicker plant proteins.
- Flour options: Try a 1:1 gluten-free baking blend or a mix of oat and almond flour (3:1).
If using almond flour, add 1 extra tbsp flour to help structure.
- Dairy-free: Use non-dairy milk and a thick coconut yogurt. Choose a vegan protein powder.
- Flavor twists: Add mini dark chocolate chips, orange zest, or a pinch of nutmeg. For a maple glaze, replace vanilla with maple extract.
- Lower sugar: Cut sugar to 1/4 cup and add a few drops of liquid stevia or monk fruit.
Expect a slightly less tender crumb.
FAQ
Can I make these without a donut pan?
Yes. Use silicone muffin cups and shape a small hole in the center with a foil ring or a greased bottle cap. They’ll be more like donut muffins, but still tasty and high in protein.
What kind of protein powder works best?
Whey isolate or a whey blend makes the softest texture.
For dairy-free, a pea-based blend is reliable. Avoid collagen alone—it doesn’t provide structure and can make the texture gummy.
Why are my donuts dry?
They were likely overcooked or the batter was too dry. Next time, reduce the cook time by 1–2 minutes, add a splash more milk to the batter, or use a touch more oil or yogurt for moisture.
Can I bake these in a regular oven?
Yes.
Bake at 350°F (175°C) for 10–12 minutes until set. The oven may yield a slightly lighter crust compared to the air fryer.
How much protein is in each donut?
It depends on your protein powder and exact ingredients. As a ballpark, using 1/2 cup whey protein for 8 donuts, you’ll get around 8–12 grams of protein per donut.
Check your labels and divide by servings.
Do I need to line the pan?
No, but a light coat of oil helps release. Silicone pans tend to release easily, while metal pans need more grease.
Can I add fruit?
Small add-ins like finely chopped strawberries or blueberries work, but keep them minimal to avoid excess moisture. Frozen berries should be thawed and patted dry first.
What glaze is healthiest?
A simple yogurt glaze (Greek yogurt, a little honey or maple, and vanilla) is a lighter option.
You can also dust with cinnamon-cocoa instead of glazing to cut sugar.
