Low-Calorie Protein Donut Holes – A Light, Satisfying Treat
These donut holes hit that sweet spot when you want something fun, quick, and not loaded with sugar. They’re soft, lightly sweet, and packed with protein so you feel satisfied. No deep fryer, no fuss—just a simple batter, a hot oven or air fryer, and a quick dusting of cinnamon “sugar.” Enjoy them as a post-workout snack, an afternoon pick-me-up, or a better-for-you dessert.
You’ll be surprised how bakery-like they taste with only a handful of simple ingredients.
Ingredients
Method
- Preheat and prep. Heat the oven to 350°F (175°C) or preheat an air fryer to 320°F (160°C). Line a small baking sheet with parchment or lightly spray the air fryer basket.
- Mix dry ingredients. In a bowl, whisk 1/2 cup protein powder, 1/2 cup white whole wheat or oat flour, 1 1/2 teaspoons baking powder, 1/4 cup granulated zero-calorie sweetener, and a pinch of salt. Break up any clumps so the batter stays smooth.
- Combine wet ingredients. In a separate bowl, stir together 1/2 cup plain nonfat Greek yogurt, 1/3 cup unsweetened applesauce, 1 egg white (or 1 whole egg for richer texture), and 1 teaspoon vanilla extract until creamy.
- Make the batter. Add the wet mixture to the dry. Stir gently until just combined. The batter should be thick and scoopable—similar to cookie dough. If it’s too dry, add 1–2 teaspoons of milk or water. If it’s too sticky, dust with a teaspoon of flour.
- Shape the donut holes. Use a small cookie scoop or spoon to portion 16 even mounds. Lightly wet your hands and roll into balls about 1 to 1 1/4 inches wide. Place on the lined sheet or in the air fryer basket, leaving a little space.
- Bake or air fry. Bake for 8–10 minutes (oven) or air fry for 6–8 minutes. They’re done when puffed, lightly golden, and a toothpick comes out clean. Don’t overbake—protein treats can dry quickly.
- Mix the coating. In a shallow bowl, combine 2–3 tablespoons granulated zero-calorie sweetener with 1–2 teaspoons cinnamon. Adjust to taste.
- Coat the donut holes. While warm, lightly brush with a tiny bit of melted light butter or mist with oil. Roll in the cinnamon-sweet mixture until well coated.
- Let them set. Cool for 5–10 minutes so the coating adheres and the texture sets. Enjoy warm or at room temp.
Why This Recipe Works
This recipe uses a balance of protein powder and flour so the donut holes stay tender, not chalky. A bit of Greek yogurt adds moisture and protein without a lot of fat. Applesauce keeps the sweetness light and helps reduce calories while maintaining a soft crumb.
Baking powder gives a nice lift, so you get that familiar donut bite without frying. And a quick cinnamon-sweet coating makes them taste like the real deal.
What You’ll Need
- Protein powder (vanilla or unflavored): Whey or a smooth plant-based blend. Choose one you like the taste of.
- White whole wheat flour or oat flour: Keeps texture light with a bit more fiber.
- Plain nonfat Greek yogurt: Adds moisture, protein, and tenderness.
- Unsweetened applesauce: Natural sweetness and moisture, with fewer calories than oil.
- Egg white (or 1 whole egg): Helps bind and create structure.
- Granulated zero-calorie sweetener: Erythritol, allulose, or your favorite blend.
Use what tastes best to you.
- Baking powder: For lift.
- Vanilla extract: Round, familiar flavor that makes them taste like donuts.
- Pinch of salt: Balances sweetness and boosts flavor.
- Cinnamon: For the coating.
- Optional: A teaspoon of melted light butter or a spritz of oil for the coating to help it stick.

Keeping It Fresh
Store leftover donut holes in an airtight container at room temperature for up to 24 hours. For longer storage, refrigerate up to 4 days.
Reheat for 10–15 seconds in the microwave or a couple of minutes in a low oven to bring back the softness. You can also freeze them for up to 2 months; thaw overnight in the fridge and warm before serving.

Common Mistakes to Avoid
- Overbaking: Even 1–2 extra minutes can dry out protein-based bakes. Check early.
- Using the wrong protein powder: Some powders are gritty or absorb too much liquid.
Choose a smooth whey or a fine-textured plant blend and avoid “weight gainer” types.
- Overmixing the batter: Stir just until combined. Overmixing can make them tough.
- Skipping the salt: A small pinch improves flavor and balances sweetness.
- Coating too late: Roll while warm so the cinnamon-sweet mix sticks well.
Recipe Variations

- Apple Cider Donut Vibes: Replace 1–2 tablespoons applesauce with reduced apple cider and add a pinch of nutmeg and cloves.
- Maple Cinnamon: Swap vanilla for maple extract and dust with a mix of sweetener, cinnamon, and a pinch of maple sugar (optional).
- Chocolate Chip: Fold in 2 tablespoons mini dark chocolate chips.
It raises calories slightly but adds rich flavor.
- Gluten-Free: Use certified gluten-free oat flour and a gluten-free protein powder. Check labels for cross-contamination.
- Dairy-Free: Use a thick dairy-free yogurt and a plant-based protein powder. You may need a teaspoon or two more liquid.
FAQ
How many calories are in each donut hole?
It depends on your protein powder and sweetener.
With the amounts listed and a whey protein, each donut hole typically lands around 45–70 calories. Use a nutrition calculator with your exact brands for a precise number.
Do I have to use Greek yogurt?
Greek yogurt works best for moisture and protein. If you don’t have it, use regular yogurt and reduce the applesauce slightly so the batter doesn’t get too thin.
Can I make these without sweetener?
Yes.
Replace the granulated zero-calorie sweetener with 2–3 tablespoons of sugar, coconut sugar, or maple syrup (reduce applesauce by 1 tablespoon if using a liquid sweetener). Calories will increase slightly.
Why did my donut holes turn out dry?
They were likely overbaked or the protein powder absorbed more liquid. Next time, check doneness earlier and add a teaspoon or two of milk to the batter if it looks stiff.
Avoid overmixing.
Can I use almond flour?
You can replace the flour with finely ground almond flour, but the texture will be more tender and slightly crumbly. Add an extra tablespoon of protein powder or a teaspoon of coconut flour to help bind.
What’s the best way to reheat?
A quick 10–15 seconds in the microwave works great. For a slight crust, warm in a 300°F (150°C) oven or air fryer for 2–3 minutes.
Can I make them in a mini muffin pan?
Yes.
Spoon the batter into a greased mini muffin pan, filling cups about 3/4 full. Bake 8–10 minutes, then roll warm “munchkins” in the cinnamon-sweet coating.
In Conclusion
These low-calorie protein donut holes deliver a soft, donut-shop feel without the extra oil or sugar. They’re quick, customizable, and easy to keep on hand for snacks or dessert.
Once you find a protein powder you love, this recipe becomes a reliable go-to. Keep a batch ready, and you’ll always have a lighter treat that actually satisfies.
