If you want a morning pick-me-up that feels indulgent but actually boosts your protein, these Air Fryer Donut Holes are the answer.
They crisp on the outside, pillow-soft inside, and roll in a warm cinnamon-sugar mix that smells like a bakery at dawn. I first made them on a sleepy Saturday when the kids wanted “donuts” but I refused to start a deep-frying habit again—this version keeps the fun, dials down the guilt, and sneaks in whey or Greek yogurt for a satisfying protein boost.
Why these Air Fryer Donut Holes are different
There are a lot of air fryer donut recipes floating around, but this one is tuned for texture: a light crust from a quick spray and a moist, tender center thanks to Greek yogurt (or protein powder if you prefer). Rather than relying on heavy oil or store-bought biscuit dough, we balance flour, egg, and a modest amount of sweetener to make a healthier, protein-packed snack.
These donut holes work for breakfast, snack time, or a quick post-workout treat. They’re adaptable—gluten-free swaps, lower-carb swaps, and flavor variations are all covered below.
Ingredients
Main batter
- 1 cup all-purpose flour (or 1:1 gluten-free flour for GF)
- 1/4 cup vanilla whey protein powder (or plain Greek yogurt; see substitutions)
- 2 tbsp coconut sugar or brown sugar
- 1 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp fine salt
- 1 large egg
- 1/3 cup plain Greek yogurt (or 1/4 cup milk + 2 tbsp oil if using protein powder)
- 1 tsp vanilla extract
Cinnamon-Sugar Coating
- 2 tbsp granulated sugar (or monk fruit/erythritol for low-calorie)
- 1 tsp ground cinnamon
- 1 tbsp melted butter or neutral oil (for coating)
Equipment
- Air fryer (basket style recommended)
- Small ice cream scoop or spoon
- Mixing bowls and whisk
- Parchment or reusable silicone liner (optional)
Step-by-step: make fluffy Air Fryer Donut Holes
1) Mix dry ingredients
Whisk the flour, protein powder (if using), sugar, baking powder, baking soda, and salt in a medium bowl until evenly combined. This ensures that every bite rises uniformly and doesn’t have pockets of leavening.
2) Combine wet ingredients
In a separate bowl, beat the egg lightly, then stir in Greek yogurt, vanilla, and, if your yogurt is very thick, a tablespoon of milk to loosen it. If you’re using protein powder instead of Greek yogurt, whisk the egg with milk and 1 tbsp oil to keep the batter moist.
3) Fold into a sticky batter
Pour the wet into the dry and fold with a spatula just until combined. The batter should be thick and slightly sticky—similar to a muffin batter. Overmixing will tighten the gluten and make the donut holes dense.
4) Shape the donut holes
Use a small cookie scoop or two spoons to portion 1-inch balls. Wet your hands lightly if the batter sticks. Place each ball on a plate or tray lined with parchment.
5) Preheat and prepare the air fryer
Preheat your air fryer to 350°F (175°C) for 3 minutes. Lightly spray the basket or line with a silicone liner to prevent sticking. Arrange the balls in a single layer with a small gap—don’t overcrowd so air can circulate.
6) Air-fry to golden
Air-fry for 6–8 minutes, flipping halfway. They should be golden brown and spring back slightly when touched. Tip: Every air fryer behaves differently; if they brown too fast, lower the temp to 330°F and add a minute or two.
7) Toss in cinnamon-sugar
While the donut holes are warm, brush them lightly with melted butter or oil, then toss in the cinnamon-sugar. The warmth helps the coating adhere and gives a classic finish.
8) Cool and enjoy
Let them cool 2–3 minutes—too hot and the interior will be gummy; too cool and the coating won’t stick as well. Serve the donut holes warm with coffee or a small bowl of greek yogurt for dipping.
Note: For a lower-calorie coating, use finely ground erythritol + cinnamon instead of sugar and brush with a tiny amount of butter alternative.
Ingredient spotlight and smart substitutions
Protein powder vs. Greek yogurt: I like using a small amount of whey for a boost without changing texture too much. If you use whey, add a touch of oil or milk to keep the dough tender. Greek yogurt gives tang and moisture—great if you want that soft, cake-like center.
- Gluten-free: Swap 1:1 gluten-free flour and check your protein powder is GF. Add 1/4 tsp xanthan gum if your flour blend lacks it.
- Vegan: Use flax egg (1 tbsp flaxseed + 3 tbsp water) and a plant-based yogurt. Choose a vegan protein powder or omit and increase yogurt slightly.
- Lower sugar: Replace sugar with powdered erythritol one-to-one in the batter and use a monk fruit blend for the coating.
- Flavor tweaks: Add 1/2 tsp cinnamon to the batter, or swap vanilla for almond extract for a more nutty aroma.
Common mistakes and how to avoid them
Too dense? You likely overmixed or overpacked the flour. Fold gently and measure flour by spooning it into the cup and leveling with a knife.
Not golden enough? Your air fryer might run cool or be overcrowded. Give space for airflow and increase temp by 10–15°F if needed.
Coating won’t stick? Brush with melted butter while warm, or use a light syrup (1 tbsp honey + 1 tbsp water) if you want a glaze effect that clings better.
Serving suggestions and pairings
These donut holes are lovely alongside a smear of nut butter, a bowl of plain Greek yogurt, or a small fruit compote. For a brunch spread, pair them with cinnamon-spiced coffee, matcha lattes, or a fruity iced tea.
Turn them savory-ish by skipping the cinnamon-sugar and tossing in a mixture of grated Parmesan and garlic powder for an unexpected snack option.
Make-ahead, storage, and reheating
Store cooled donut holes in an airtight container at room temperature for up to 2 days. For longer storage, freeze them in a single layer on a tray, then transfer to a freezer-safe bag for up to 1 month.
To reheat, pop frozen or room-temp donut holes into the air fryer at 320°F for 3–4 minutes until warmed through. This brings back the crisp outer texture much better than a microwave.
Variations and flavor twists
- Chocolate-hazelnut: Stir 2 tbsp cocoa powder into the batter and roll warm holes in powdered sugar.
- Apple-cider: Replace half the liquid with apple cider and use apple pie spice in the coating.
- Lemon glaze: Make a thin glaze with powdered sugar and lemon juice and drizzle over cooled donut holes.
FAQ
Can I make these Air Fryer Donut Holes without protein powder?
Yes — use 1/3 cup Greek yogurt instead of protein powder and slightly reduce the milk if your batter becomes too loose. They’ll be just as tender, just with a little less protein per serving.
How many donut holes does this recipe yield?
Expect about 16–18 one-inch donut holes, depending on how big you scoop them. That makes roughly 8 servings if sharing two each, or 4–6 snack portions for hungry kids.
Will they work in a convection oven?
Absolutely. Bake at 350°F in a preheated oven on a lined baking sheet for 10–12 minutes, flipping or rotating halfway for even browning.
Can I use canned biscuit dough instead of making batter?
You can, but texture and nutrition change—canned dough is more enriched and often higher in fat. If you choose canned biscuits, cut them into small pieces and air-fry per the package guidance (usually around 6–8 minutes), then toss in cinnamon-sugar.
Are these suitable as post-workout snacks?
Yes — the protein from whey or Greek yogurt helps muscle recovery, and the carbs refuel glycogen. Aim for a balance: pair a few donut holes with a small glass of milk or a yogurt dip for a more complete recovery snack.
Nutrition snapshot
This is an estimate per serving (4 donut holes): moderate calories, with a good protein hit if you add whey or use Greek yogurt. Exact values depend on ingredients and portion size—see the recipe card below for the nutrition in the structured data.
