The 3-Step Bake: in practice
Why Air Frying Donuts Wins
Using an air fryer for donuts creates a better texture than a conventional oven. The concentrated heat circulation gives the exterior a slight crust while keeping the inside moist.
You save roughly $5 per batch compared to buying pre-made store protein snacks. Plus, you control exactly what goes into your body.
- Uses 50% less energy than a full-size oven.
- Cooks 4 donuts perfectly in 10 minutes.
- Ideal for single-serving cravings.
Choosing the Right Protein Powder
Not all powders behave the same in a baked recipe. Whey concentrate tends to dry out quickly, while a whey-casein blend mimics the structure of wheat flour better.
If you use a plant-based protein, add an extra 1 tbsp of almond milk. These powders absorb moisture rapidly, which can lead to a crumbly donut.
- Use a whey-casein blend for best rise.
- Check labels for hidden sugars or fillers.
- Avoid collagen peptides for the main structure.
Mastering the Low-Carb Batter
The secret to a non-rubbery donut is avoiding over-mixing. Stir the wet and dry ingredients just until combined, then stop immediately.
Adding a small pinch of xanthan gum helps bind the dough without needing gluten. A little goes a long way, usually just 1/4 tsp per batch.
- Use superfine almond flour for best texture.
- Add 1/2 tsp of baking powder for lift.
- Fold in sugar-free chocolate chips last.
Pros and honest limits
- Low carb profile
- Fast cook time
- Customizable flavors
- Requires silicone molds
- Texture differs from fried

Storage and Reheating Tips
These donuts stay fresh for 3 days in an airtight container at room temperature. For longer storage, keep them in the fridge for up to 7 days.
If you want that fresh-out-of-the-fryer taste, pop them back into the air fryer at 300°F for 2 minutes. They will crisp right back up perfectly.
- Freeze for up to 30 days for meal prep.
- Reheat from frozen in 4 minutes at 300°F.
- Keep away from direct sunlight for freshness.

Frequently asked questions
Can I use coconut flour instead?
Yes, but you need to use 1/3 the amount of almond flour and add an extra egg. Coconut flour is extremely absorbent.
Why are my donuts rubbery?
You likely over-mixed the batter or used too much protein powder. Stick to the ratios provided and stir gently.
Do I need a specific air fryer?
Any standard air fryer works. Just ensure your silicone mold fits inside the basket with at least 1 inch of clearance on the sides.
How many calories per donut?
Each donut contains roughly 160 calories depending on your specific protein powder brand.
