Can You Put Donuts in an Air Fryer?
Yes, you absolutely can put donuts in an air fryer. In fact, it’s one of the most effective ways to reheat a donut and make it taste nearly as good as the moment it came out of the fryer. Air fryers work by circulating hot air at high speed around the food, which creates a crispy outer layer while heating the interior evenly. This is exactly what a stale or cold donut needs.
The question “Can you put donuts in an air fryer?” comes up because donuts are delicate pastries, and many people have been burned by bad reheating methods in the past. The microwave ruins them. The oven dries them out. The air fryer, however, strikes the perfect balance. It warms the donut through quickly and adds back a pleasant crispiness that makes it feel fresh-baked again. Whether you’re working with glazed, frosted, cake, or yeast donuts, the air fryer can handle them all with just a little care and attention.
What Happens to Donuts in an Air Fryer?
When you place a donut in an air fryer, the circulating hot air works on two fronts. First, the surface of the donut is exposed to high heat, which drives out surface moisture and creates a light, crispy crust. This is what makes the donut taste “fried” and fresh again. Second, the heat slowly penetrates to the center, warming the interior without turning it into a dense, chewy mass.
This dual action is why air-fried donuts come out superior to microwave-warmed ones. The microwave heats water molecules rapidly, which creates steam inside the donut. That steam softens the gluten and can turn a light, airy donut into a gummy puck. The air fryer, by contrast, is a dry heat method, so it removes moisture from the outside rather than trapping it inside. The result is a donut that is crunchy on the outside, fluffy on the inside, and exactly the kind of texture you want from a warm breakfast treat.
It’s worth noting that air frying doesn’t actually fry anything in the traditional sense. There’s no oil involved. But because donuts are already fried, the air fryer simply restores the original texture by reheating the residual oils and adding a fresh, hot surface. The effect is almost magical, especially for day-old donuts that have lost their charm.
Air Frying Different Types of Donuts
Not all donuts are created equal, and each type needs its own slightly different treatment in the air fryer. Here’s how to handle the most common varieties.
Yeast Donuts
Yeast donuts are the classic light and fluffy kind you get at most donut shops. They’re made from a yeasted dough that rises before being fried, which gives them their airy interior. When reheating a yeast donut in the air fryer, you want to be careful not to overdo it. At 350°F (175°C), a plain yeast donut takes just 2 to 3 minutes. Flip it halfway through to keep the exterior evenly crispy. Because yeast donuts are so delicate, they can easily go from perfect to dry in under a minute, so keep a close eye on the time.
Cake Donuts
Cake donuts are denser and crumbly, more like a cupcake in donut form. They hold up much better to heat and can handle a slightly longer reheat time. Aim for 3 to 4 minutes at 350°F (175°C). Cake donuts also benefit from the air fryer because the crisp exterior contrasts beautifully with their dense, moist interior. If your cake donut has cinnamon sugar on top, the air fryer will also help refresh that coating just the way it should be.
Glazed Donuts
Glazed donuts require a little more care. The sugar glaze can melt and drip off if the temperature is too high. It’s best to air fry them at a lower temperature, around 320°F (160°C), for just 2 minutes. This warms the donut and re-softens the glaze without turning it into a sticky puddle. If your glaze has already begun to crystallize from sitting out, the air fryer will actually help it re-melt slightly and look glossy again, which is a huge win.
Filled Donuts
Filled donuts, such as jelly or cream-filled treats, are tricky because the filling heats up much faster than the dough. Use a lower temperature of 320°F (160°C) and heat for 2 to 3 minutes. Be sure to let them rest for about 1 minute before taking a bite, because the filling can become dangerously hot. You don’t want to burn the roof of your mouth on raspberry jam.
How to Warm Donuts in an Air Fryer: Step-by-Step
Here’s the simplest step-by-step method for warming a donut in the air fryer. This works for most plain, glazed, and cake-style donuts.
- Preheat your air fryer to 350°F (175°C). Preheating is important because it ensures the donut hits warm air immediately, giving you an even crisp exterior.
- Place your donut in the air fryer basket. Leave plenty of room around the donut for air to circulate. Don’t overcrowd the basket; if you need to reheat multiple donuts, do them in a single layer with space between each one.
- Heat for 2 to 3 minutes. Start with 2 minutes and check the donut. If it’s not warm enough or crispy enough, add another minute.
- Flip halfway through. At the 1-minute mark, flip the donut with a pair of tongs to ensure both sides get the same crisp treatment.
- Remove and let cool for one minute. The donut will be hot, and letting it rest helps the interior finish warming while the outside stays crunchy. Then dig in and enjoy.
This basic method works for the vast majority of donuts. For heavier cake donuts, add an extra minute. For lighter glazed donuts, reduce the temperature to 320°F. The key is always to start low and check frequently because air fryers are powerful and the difference between a perfect donut and a dry one is often just 30 seconds.
How to Make Donuts Extra Crispy
If you have a donut that has gone stale and lost its crunch, there are a few tricks to restore some crispness in the air fryer. One method is to brush a thin layer of butter or oil over the donut before air frying. This adds a little fat to the surface, which helps brown and crisp up the exterior. Use a light hand, though. You don’t want a greasy donut.
Another approach is to use a slightly lower temperature and a longer cook time. This allows more moisture to escape from the surface without burning the sugar or glaze. Try 300°F (150°C) for 4 minutes to see if that gets you the crunch you’re looking for.
You can also let the donut cool for 1 to 2 minutes after air frying and then pop it back in for another 30 seconds. This second pass creates a very crunchy shallow crust, perfect for those who like their donuts on the crispier side. Just be careful not to overdo it or you’ll end up with something closer to a stale, dry biscuit.
Air Fryer Donut Temperature and Time Chart
Use this quick reference chart as your go-to guide for air-frying donuts. These times assume a standard air fryer at full capacity and a donut that is at room temperature before placing it in.
| Donut Type | Temperature | Time | Notes |
|---|---|---|---|
| Yeast donut (plain) | 350°F (175°C) | 2–3 minutes | Flip halfway for even crispness |
| Glazed donut | 320°F (160°C) | 2 minutes | Lower heat to keep glaze intact |
| Cake donut | 350°F (175°C) | 3–4 minutes | Dense texture needs more time |
| Filled donut | 320°F (160°C) | 2–3 minutes | Let cool 1 minute before eating |
| Frosted donut | 300°F (150°C) | 1–2 minutes | Brief heat only to avoid melting |
| Donut holes | 350°F (175°C) | 2–3 minutes | Shake the basket halfway |
Remember, every air fryer is different. A 2,000-watt air fryer will cook faster than an older model with less wattage. These times are starting points, not hard rules. Always check on your donut at the lower end of the range and decide from there.
Do’s and Don’ts of Air-Frying Donuts
To get the best results every time, follow these simple do’s and don’ts.
Do
- Do preheat the air fryer. This is the single biggest factor in getting a crispy exterior. A donut placed in a cold air fryer will absorb heat slowly and end up soft rather than crunchy.
- Do leave space between donuts. Air fryers work by circulating air around the food. If the basket is packed, the air can’t flow and you’ll get uneven results.
- Do check early and often. Donuts reheat very quickly. Check at the 1-minute mark, then again at 2 minutes, even if the recipe says 3 minutes.
- Do use tongs when flipping. If you have frosted or glazed donuts, your fingers will make a mess and leave fingerprints in the glaze. Tongs keep everything clean.
Don’t
- Don’t use the air fryer on frosted donuts unless you’re careful. Chocolate frosting, cream cheese icing, and similar toppings will melt and slide right off at high temperatures. Stick to 300°F and 1 minute or less.
- Don’t place parchment paper or a liner without weighing it down. Light parchment can get blown into the heating element and cause a fire hazard. If you use it, make sure donuts hold it down or cut it to fit exactly.
- Don’t reheat a donut that has dairy cream filling. Cream fillings can curdle or separate when reheated. It’s better to eat those cold or at room temperature.
- Don’t walk away. A donut can go from perfect to burnt in under a minute. Set a timer and stay nearby.
Air Fryer vs Microwave vs Oven
If you’re wondering whether the air fryer is really worth the extra effort compared to other methods, here’s a side-by-side comparison. Each method has its fans, but the air fryer tends to come out on top for taste and texture.
| Method | Texture Result | Total Time | Best For | Main Risk |
|---|---|---|---|---|
| Air Fryer | Crispy outside, soft inside | 2–4 minutes | Most donut types | Overheating delicate ones |
| Microwave | Soft, steamy, often rubbery | 10–15 seconds | Cake donuts in a pinch | Sogginess and toughness |
| Oven | Evenly warm, lightly crisp | 5–8 minutes | Large batches | Drying out the donut |
As you can see, the air fryer offers the best balance of speed, texture, and versatility. The microwave is fast but reliable only for cake donuts and even then, it’s a compromise. The oven is fine for warming a whole box of donuts at once, but the dry heat of a conventional oven tends to pull moisture from the pastry, leaving it slightly brittle. The air fryer gives you that fresh-from-the-fryer experience in just a few minutes.
Can You Reheat Frosted or Glazed Donuts?
Yes, but you have to use a gentle approach. Frosted donuts, especially those with chocolate icing or a thick drizzle, are the most challenging. At high temperatures, the frosting will melt and slide off, which leaves you with a bare donut and a mess in the basket. The trick is to use a very low temperature—around 300°F (150°C)—and a very short time, just long enough to warm the donut through without turning the frosting into liquid.
For glazed donuts, the situation is a bit easier. The sugar glaze is already liquid at room temperature in most cases, so a low-heat air fry for 2 minutes won’t cause much of an issue. In fact, it can help re-melt the glaze slightly, giving the donut that shiny, bakery-fresh appearance again. Just don’t place a frosted donut directly on the air fryer rack or you’ll have a sticky, melted disaster on your hands. Instead, let it cool for a few minutes after air frying so the frosting has time to re-set.
Can You Air Fry Raw Donut Dough?
When people ask “Can you put donuts in an air fryer?” they sometimes mean raw dough, not just leftovers. The answer is yes, but with some caveats. The air fryer can actually bake or cook donut dough effectively because it acts like a small convection oven. You can use prepared donut dough from the store, like canned biscuit dough, or your own homemade yeasted dough.
To air fry raw donut dough, shape the dough into donut rings or donut holes, give them a little space in the basket, and cook at 350°F (175°C) for 5 to 7 minutes, flipping halfway through. The outside will brown and form a nice crust, and the inside will cook through. The texture won’t be exactly like a deep-fried donut because there’s no oil bath, but it’s a lower-effort alternative that still yields a warm, doughy treat.
If you want to mimic that fried taste, you can brush the raw dough with a bit of melted butter or oil before air frying. This helps with browning and gives a slightly richer flavor. You can also toss the finished donuts in melted butter and cinnamon sugar right after they come out, just like a classic cinnamon sugar donut.
Tips for the Best Air-Fried Donuts
These tips will help you get the most out of your air fryer whether you’re reheating leftovers or experimenting with raw dough.
- Let the donut come to room temperature first. If your donut is cold from the fridge, let it sit out for 10 to 15 minutes before air frying. This helps it warm evenly and reduces the cooking time needed.
- Paper towels and glaze mess. If you’re reheating a heavily glazed donut, lay a piece of parchment paper under it to catch drips. It makes cleanup much easier.
- Add a tiny touch of freshness. After air frying, brush a glazed donut with a little warm butter or honey if you want it extra decadent. This elevates it beyond what it was originally.
- Cold donuts in the fridge? Donuts actually store best in a paper bag at room temperature, not in the fridge. The fridge dries them out faster. But if yours are refrigerated already, the air fryer is still your best option to revive them.
- Match the donut size. Mini donuts and donut holes need less time than full-size donuts. Reduce the time by about half if you’re reheating smaller portions.
- Experiment with toppings. Once the donut comes out warm, sprinkle on powdered sugar, cinnamon, or a drizzle of caramel sauce. The warmth helps the toppings stick.
Frequently Asked Questions
Can you put donuts in an air fryer without turning them into a mess?
Yes, with the right temperature and time. Stick to the chart above, use low heat for frosted and glazed varieties, and always place a liner or simply clean the basket afterward. The key is to keep the temperature moderate and set a timer so you don’t accidentally overheat them.
How long should I air fry a donut?
For most donuts, 2 to 3 minutes at 350°F (175°C) is enough. Glazed and frosted donuts do better at 300 to 320°F (150–160°C) for just 1 to 2 minutes. Cake donuts can go up to 4 minutes if needed.
Can I make donuts from scratch in an air fryer?
Yes, you can make a baked or air-fried version of donuts from scratch. The texture will be closer to a cake donut than a traditional fried yeast donut, but it’s still delicious and much healthier. Many people use canned biscuit dough to make quick air-fried donut holes.
Why did my donut go dry in the air fryer?
Most likely, you left it in for too long or the temperature was too high. Air fryers can dry out baked goods quickly. Always check the donut at the 1-minute mark and adjust from there. Also, don’t pre-cut or poke holes in the donut because you’ll create pathways for moisture to escape.
Can I reheat a Boston cream donut in an air fryer?
It’s not recommended. The cream filling can become too hot and turn liquid, creating a mess and potentially burning your mouth. Boston cream donuts are best enjoyed cold or at room temperature.
Should I put a donut in the air fryer from the freezer?
Yes, you can air fry frozen donuts. Add 1 to 2 extra minutes to the cook time and check frequently. No need to thaw first; the air fryer will handle both warming and crisping.
Conclusion
So, can you put donuts in an air fryer? Absolutely. The air fryer is a game-changer when it comes to reviving day-old donuts, restoring their crispy edges, and making them taste warm and fresh again. Whether you’re reheating a classic glazed yeast donut, a dense cake donut, or even experimenting with raw donut dough, the air fryer delivers far better results than a microwave and beats the oven in both speed and texture.
The golden rules to remember are: preheat your air fryer, use a moderate temperature based on the donut type, check often, and don’t overload the basket. With a little practice, you’ll be able to bring any donut back to life in minutes. So next time you have a leftover donut that’s lost its spark, skip the microwave and give it the air fryer treatment. Your taste buds will thank you.
