Reheating donuts sounds simple, until you end up with a dry ring of regret or a melted sugar mess. If you’ve ever wondered how to reheat Krispy Kreme donuts in an air fryer without ruining that signature soft crumb and glossy glaze, this guide is for you. I’ve tested this in a real home kitchen with day‑old, two‑day‑old, and even chilled donuts, and the method below delivers warm, bakery‑soft results when done correctly.
The Real Problem With Reheating Krispy Kreme Donuts
Krispy Kreme donuts are different from standard cake donuts. They’re yeast‑raised, high‑moisture, and glazed, which makes them incredibly soft when fresh, and surprisingly easy to overcook when reheating.
What most beginners don’t realize is that:
- Too much heat dries out the interior fast
- The glaze can melt, burn, or slide right off
- Microwaving makes them hot but rubbery, not fluffy
After repeated testing, the air fryer turns out to be the best balance, if you control temperature, timing, and placement. Used correctly, it revives softness and warmth without turning the donut into toast.
Why This Method Works
Understanding a little kitchen science helps you get reliable results.
Krispy Kreme donuts contain:
- High moisture from yeast fermentation
- Sugar‑based glaze that melts quickly
- Very little structural fat compared to fried cake donuts
The air fryer works because:
- Gentle circulating heat warms the interior evenly
- Short cook time prevents moisture loss
- Low temperature avoids glaze burning
In real kitchens, the mistake I see most often is treating donuts like leftover pizza, too hot, too long. With donuts, slower and gentler wins every time.
Ingredients & Tools You’ll Need
Ingredients
- Krispy Kreme donuts (original glazed or filled)
Tools
- Air fryer (basket or oven-style both work)
- Parchment liner or perforated air fryer paper (optional but helpful)
- Tongs or clean fingers (for quick removal)
- One 48-fluid-ounce container of Cookies & Cream Ice Cream Some of your favorite Amazon Fresh products are now part of th…
Notes & Substitutions

How to Reheat Krispy Kreme Donuts in an Air Fryer
Step 1: Preheat the Air Fryer (Optional but Recommended)
- Temperature: 300°F (150°C)
- Time: 2–3 minutes
From testing, preheating helps prevent uneven warming and reduces the time the glaze is exposed to heat.
Step 2: Prepare the Donuts
- Remove donuts from packaging
- If refrigerated, let sit at room temperature for 5 minutes
- Place donuts in a single layer
- Leave space between donuts—no stacking
Optional: Place parchment underneath to catch glaze drips.
Step 3: Reheat Gently
- Temperature: 300°F (150°C)
- Time:
- 2–3 minutes for room‑temperature donuts
- 3–4 minutes for refrigerated donuts
Visual cues to watch for:
- Glaze becomes glossy and slightly shiny
- Donut feels warm but still soft when pressed
- No browning or sizzling should occur
If you smell toasted sugar, stop immediately—that’s your warning sign.
Step 4: Remove and Rest Briefly
- Remove donuts immediately with tongs
- Let rest 30–60 seconds
This short rest allows:
- Heat to finish distributing
- Glaze to set slightly instead of sliding off
Pro Tips & Best Practices (From Real Kitchen Testing)
- Lower heat is better than longer time. Never exceed 325°F.
- Don’t walk away. Donuts go from perfect to ruined fast.
- Reheat once only. Reheating twice dries the crumb.
- Filled donuts: Add 30 seconds, but check early, fillings heat faster than dough.
- Multiple donuts: Reheat in batches for even results.
- Avoid oil sprays. Donuts already contain fat; extra oil ruins texture.
Common Beginner Mistakes
- Using 350°F like frozen snacks
- Stacking donuts
- Reheating straight from the freezer
- Leaving donuts inside after turning the air fryer off
FAQ: Real Questions Home Cooks Ask
Why did my Krispy Kreme donut turn dry in the air fryer?
The temperature was too high or it stayed in too long. Yeast donuts lose moisture quickly over 325°F.
Can I reheat Krispy Kreme donuts straight from the fridge?
Yes, but let them sit out for 5 minutes and add only 30–60 seconds extra cook time.
Is the air fryer better than the microwave?
For texture, absolutely. Microwaves heat unevenly and make yeast donuts rubbery. The air fryer preserves softness when used gently.
Can I reheat chocolate‑iced or sprinkled donuts?
Chocolate‑iced works well. Sprinkles may melt or slide—watch closely and shorten time.
How long should I reheat a filled Krispy Kreme donut?
Usually 3–4 minutes at 300°F, checking at the 2½‑minute mark.
Is it safe to reheat donuts?
Yes, as long as they were stored properly and reheated once. Discard donuts that smell sour or feel excessively hard.

Oven (Gentle but Slower)
Pros: Even heating Cons: Longer time, dries glaze Best for: Large batches
Toaster Oven
Pros: Controlled heat Cons: Easy to overcook Best for: One donut, closely monitored
Overall Winner: Air fryer at low temperature
Conclusion: The Best Way to Reheat Krispy Kreme Donuts in an Air Fryer
Once you understand how delicate Krispy Kreme donuts really are, reheating them becomes simple. Using an air fryer at 300°F for just a few minutes is the most reliable way to restore warmth, softness, and that signature glaze without drying them out.
From repeated home kitchen testing, this method works because it respects the donut’s structure instead of fighting it. Take it slow, watch closely, and trust your senses, soft touch, glossy glaze, warm aroma.
Handled properly, reheated donuts can still feel like a small bakery treat, not leftovers.
