Ingredients Method

Ingredients

  

• 1 cup (120 g) oat flour or finely ground oats
• 1/2 cup (45–50 g) vanilla whey or plant-based protein powder
• 1 1/2 tsp baking powder
• 1/4 tsp baking soda
• 1/4 tsp fine salt
• 1 tsp ground cinnamon (optional but nice)
• 1/3 cup (80 g) nonfat Greek yogurt
• 1/2 cup (120 ml) unsweetened almond milk (or skim milk), plus 1–2 tbsp more if needed
• 1 large egg (or 1 flax egg for vegan: 1 tbsp ground flax + 3 tbsp water, rested 10 minutes)
• 2–3 tbsp granulated sweetener of choice (sugar, coconut sugar, or zero-cal sweetener)
• 1 tsp vanilla extract
• 1 tbsp light butter or neutral oil (optional, for moisture)
• 2 tbsp zero-cal sweetener or fine sugar
• 1 tsp cinnamon
• 1–2 tsp melted light butter or a quick spritz of oil
• 1/2 cup powdered sweetener (regular or zero-cal)
• 1–2 tbsp unsweetened almond milk
• 1/2 tsp vanilla extract

Method

 

1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease a mini muffin tin.
2. In a mixing bowl, whisk together the oat flour, protein powder, baking powder, baking soda, salt, and cinnamon.
3. In another bowl, whisk the Greek yogurt, milk, egg, sweetener, vanilla, and light butter or oil until smooth.
4. Pour the wet ingredients into the dry. Stir gently until just combined. The batter should be thick but scoopable. If it’s too dry or crumbly, add 1–2 tablespoons more milk.
5. Use a small cookie scoop or spoon to portion 1–1.5 tablespoon mounds. For a baking sheet, roll lightly with damp hands into balls. For a mini muffin tin, simply scoop into each cavity.
6. Bake for 9–12 minutes, until the tops spring back when touched and a toothpick comes out clean. Avoid overbaking so they stay moist.
7. Cool for 5 minutes. For the cinnamon “sugar,” brush or spritz each donut hole with a tiny bit of melted butter or oil, then roll in the cinnamon-sweetener mix. For the glaze, whisk the ingredients until smooth and dip the tops, letting excess drip off.
8. Let set for a few minutes, then enjoy warm or at room temperature.

   Stir gently until just combined. The batter should be thick but scoopable. If it’s too dry or crumbly, add 1–2 tablespoons more milk.

5. Use a small cookie scoop or spoon to portion 1–1.5 tablespoon mounds.

   For a baking sheet, roll lightly with damp hands into balls. For a mini muffin tin, simply scoop into each cavity.

Keeping It Fresh

• Room temperature: Store in an airtight container for up to 24 hours for best texture.
• Refrigerator: Keeps well 3–4 days. Warm in the microwave for 8–10 seconds to soften.
• Freezer: Freeze on a tray, then bag for up to 2 months.

  Thaw at room temp or microwave 15–20 seconds.

• Hold glaze if freezing: Glaze after thawing for a cleaner finish and better texture.

Why This is Good for You

• Protein supports fullness: Helps curb cravings and keeps you satisfied between meals.
• Lower sugar than classic donuts: You control the sweetness and can use zero-cal alternatives.
• Whole-grain oats: Oat flour adds fiber for steady energy and a tender crumb.
• Baked, not fried: Fewer calories from oil while still delivering a satisfying bite.

Pitfalls to Watch Out For

• Using too much protein powder: Overpacking the scoop or adding extra can make them dry and rubbery.
• Overbaking: Even 2–3 minutes too long dries them out. Pull them when they spring back.
• Dry batter: Protein absorbs liquid fast. If the batter looks stiff, add a splash more milk.
• Skipping salt or vanilla: These small touches boost flavor, especially with low-sugar bakes.
• Glaze overload: A thin coat goes a long way—too much adds calories and can make them soggy.

Variations You Can Try

• Chocolate Lover: Use chocolate protein powder, add 1 tbsp cocoa powder, and finish with a light chocolate drizzle.
• Blueberry Burst: Fold in 1/3 cup fresh blueberries and a pinch of lemon zest.
• Apple Cinnamon: Add 1/3 cup finely diced apple and a dash of nutmeg.

  Great with the cinnamon “sugar.”

• Maple Glazed: Use a few drops of maple extract in the glaze for classic donut-shop vibes.
• Vegan Option: Use plant-based protein, a flax egg, and non-dairy yogurt. Add an extra tablespoon of milk if needed.
• Birthday Cake: Stir in rainbow sprinkles and use vanilla glaze with a few more on top.

FAQ

Can I use all-purpose flour instead of oat flour?

Yes. Swap 1 cup all-purpose flour for the oat flour.

The texture will be a bit lighter and more cake-like. Keep an eye on moisture and add a splash of milk if the batter looks thick.

Which protein powder works best?

Whey blends bake up soft and moist. Plant-based powders also work but can be more absorbent, so add 1–2 extra tablespoons of milk if the batter seems dry.

Avoid collagen alone—it doesn’t provide the same structure.

How many calories are in each donut hole?

It depends on brands and add-ins, but a plain, unglazed donut hole typically lands around 45–70 calories with 4–6 grams of protein. Glaze or sugar coating will add a bit more.

Can I make these without eggs?

Absolutely. Use a flax egg (1 tbsp ground flax + 3 tbsp water, rested 10 minutes).

For extra moisture in vegan versions, add 1 more tablespoon of milk if needed.

Do I need a donut hole pan?

No. A mini muffin tin works perfectly, or you can scoop onto a parchment-lined tray and shape gently with damp hands.

Why did mine turn out dry?

Common culprits are too much protein powder, overbaking, or a batter that’s too thick. Next time, measure carefully, bake just until springy, and add a splash more milk to loosen the batter.

Can I air-fry them?

Yes.

Air-fry at 325°F (165°C) for 6–9 minutes, checking early. Line the basket with parchment and avoid crowding.
