18g High Protein Greek Yogurt Donuts Air Fryer - Easy, Fluffy, and Guilt-Friendly
Ingredients
- 1 cup (240 g) nonfat or 2% plain Greek yogurt (strained/thick works best)
- 1 large egg
- 1/2 cup (60 g) vanilla whey protein powder (or unflavored; see notes)
- 3/4 cup (90 g) all-purpose flour (or 1:1 gluten-free blend)
- 2 tbsp (16 g) cornstarch (helps tenderness)
- 1/3 cup (65 g) granulated sweetener (sugar or a 1:1 zero-cal sweetener)
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp fine salt
- 1 1/2 tsp vanilla extract
- 2 tbsp (28 g) light butter or neutral oil (melted; optional for moisture)
- 2–3 tbsp milk (dairy or unsweetened almond; as needed to loosen batter)
- Nonstick spray
- For topping (optional): 1/3 cup powdered sugar + 1–2 tbsp milk for glaze, or cinnamon sugar
Instructions
- Prep the air fryer and pan: Preheat your air fryer to 320°F (160°C). Lightly spray silicone donut molds or a donut pan that fits your basket. If you don’t have molds, shape thick batter rings on small parchment squares.
- Mix dry ingredients: In a bowl, whisk flour, protein powder, cornstarch, baking powder, baking soda, salt, and sweetener. Breaking up clumps prevents dense spots.
- Mix wet ingredients: In another bowl, whisk Greek yogurt, egg, vanilla, and melted light butter/oil until smooth.
- Combine: Add dry to wet. Stir gently until just combined. If too thick to pipe, add 2–3 tbsp milk, 1 tbsp at a time. The batter should be thick but scoopable.
- Fill molds: Spoon or pipe batter into the donut molds, filling about 3/4 full. Smooth the tops with a damp spoon for even rise.
- Air fry: Cook at 320°F (160°C) for 6–8 minutes until set and lightly golden. A toothpick should come out clean or with a few moist crumbs. Avoid overcooking—protein dries fast.
- Cool and finish: Let donuts rest in the molds for 5 minutes, then transfer to a rack. Glaze while slightly warm or dust with cinnamon sugar. For glaze, whisk powdered sugar with milk to a drizzle.
- Serve: Enjoy warm for the softest texture. Each donut targets about 18 g protein depending on your protein powder and glaze.
What Makes This Special
Most donuts are fun but don’t do much for your protein goals. These flip the script while keeping the comfort food vibe.
Greek yogurt adds moisture and protein, while whey helps you hit that 18g mark without turning the texture rubbery. Baking powder keeps them fluffy, and a few smart swaps cut down on fat and sugar. Best of all, they cook in about 6–8 minutes in the air fryer.

Keeping It Fresh
These are best the day they’re made, but they store nicely.
Keep in an airtight container at room temperature for 24 hours or refrigerate for up to 4 days. Reheat in the air fryer at 300°F (150°C) for 2–3 minutes to bring back softness. For longer storage, freeze for up to 2 months.
Thaw in the fridge, then warm before serving.
Benefits of This Recipe
- High protein: Around 18 g per donut when using whey and Greek yogurt.
- Lower fat than fried: Air frying cuts oil without losing that satisfying bite.
- Quick and flexible: Simple pantry ingredients, ready in under 20 minutes.
- Customizable sweetness: Works with sugar or zero-cal sweeteners.
- Meal prep friendly: Easy to batch, freeze, and reheat.
What Not to Do
- Don’t overmix the batter. Overworking leads to tough donuts, especially with protein powder.
- Don’t crank the heat too high. High temps brown fast outside but leave the center gummy.
- Don’t skip cornstarch or a bit of fat. These help tenderness and moisture. All-lean can taste dry.
- Don’t overfill molds. Overfilling causes mushroom tops and uneven cooking.
- Don’t rely on time alone. Check doneness with a toothpick and a gentle press for springiness.
Variations You Can Try
- Chocolate Protein Donuts: Swap 2 tbsp flour for cocoa powder. Use chocolate whey.
Add mini dark chips.
- Cinnamon Roll Style: Add 1 tsp cinnamon to batter. Glaze with a light cream cheese icing.
- Lemon Poppyseed: Stir in 1 tbsp lemon zest, 1 tbsp lemon juice, and 1 tsp poppyseeds. Finish with a lemon glaze.
- Maple Glazed: Use maple extract in the batter and a maple-powdered sugar glaze.
- Apple Pie: Fold in finely diced apple (pat dry) and extra cinnamon; keep pieces small to avoid sogginess.
- Gluten-Free: Use a 1:1 GF flour and ensure your whey is gluten-free.
Texture stays close to the original.
- Dairy-Free: Swap Greek yogurt with a thick dairy-free yogurt and use a plant-based protein powder. Note: texture may be a bit denser; add 1–2 tsp oil if needed.
FAQ
How do I make sure each donut hits 18 g of protein?
Use a whey isolate or whey blend with around 20–25 g protein per 30 g scoop and keep the full cup of Greek yogurt. Portion the batter evenly across six donuts.
Glazes don’t add protein, so the powder and yogurt do the heavy lifting.
Can I use casein or plant-based protein?
Yes, but adjust liquids. Casein thickens more; you’ll likely need 1–2 extra tablespoons of milk. Plant proteins can be gritty—choose a fine pea/rice blend and add 1 teaspoon oil for tenderness.
What if I don’t have donut molds?
Pipe thick rings onto small parchment squares and lift them into the air fryer.
Keep rings about 3 inches wide with a 1-inch hole. They won’t be perfect circles, but they’ll taste great.
Why are my donuts dry or rubbery?
That’s usually from overcooking or too much protein powder. Bake at 320°F and pull them as soon as they’re set.
Measure protein by weight if possible and don’t overmix.
Can I bake these in a regular oven?
Yes. Bake at 350°F (175°C) for 9–12 minutes, depending on your pan. Check at 9 minutes and remove when a toothpick comes out clean.
What sweetener works best?
Regular sugar gives the most consistent texture.
For lower calories, use a 1:1 erythritol or allulose blend. Allulose browns faster, so keep an eye on color.
How do I get a smooth, bakery-style glaze?
Use powdered sugar, a pinch of salt, a splash of vanilla, and milk to thin to a slow ribbon. Dip cooled donuts, let excess drip, and set on a rack for 10–15 minutes.
Can I add toppings like sprinkles or nuts?
Absolutely.
Press them onto the glaze while it’s still tacky. For nuts or seeds, toast lightly first for more flavor.
How many donuts does this make?
Usually 6 standard-size donuts. If using mini molds, you’ll get 10–12 minis; reduce cook time to 4–5 minutes.
Do I need to strain the yogurt?
If your yogurt is very thick (like most Greek yogurt), no.
If it’s loose, strain for 15–20 minutes to remove excess whey. A thicker yogurt helps the donuts hold shape and rise evenly.
In Conclusion
These 18g High Protein Greek Yogurt Air Fryer Donuts bring the best of both worlds: comfort and macros that make sense. They’re fluffy, quick, and easy to customize.
Keep a batch on hand for busy mornings, gym days, or when a sweet craving hits. With a few pantry staples and your air fryer, you’ll have warm, golden donuts ready in minutes.
