Doneness
The domed top is lightly re-crisped and fragrant; the crumb is soft and just slightly steamy when you break one open. Blueberries re-warm juicy; chocolate chips re-soften to glossy and melty; banana-nut muffins smell distinctly of warm banana. If the centre feels cool at 2 minutes, give it the final minute. Scorched or dry crumbly crumb means the temp was too high or the steam step was skipped.
Technique
Stand muffins upright (domed top up) on a parchment-paper liner with ½-inch gaps — do not let them touch. Set a small ramekin with 1 tsp water on the basket floor beneath the rack; this gentle steam re-moistens the crumb while convection heat re-crisps the top. No oil, no preheat. Do not add butter or jam before cooking — spread them after pulling. Set 300 °F (149 °C) for 3 minutes with no flip. Pound-cake or loaf-format slices reheat the same way laid flat.
Watch out for
- Use 300 °F, not 350 °F. The high-sugar domed top scorches to dry, bitter brown at 350 °F within about 2 minutes — before the dense crumb warms through. If your air fryer runs hot, drop to 290 °F.
- Use the 1 tsp water steam step. A day-old muffin has dried out; dry convection heat alone hardens the crust and dries the crumb. Place the water in a small heat-safe ramekin or foil cup on the basket floor — do not pour it directly onto the basket base, as most single-basket fryers have a heating element under the grate that is not water-rated.
- Do not microwave leftover muffins. Even 45 seconds turns the crumb rubber-tough and gummy. The air fryer at 300 °F with the steam step is the only home method that restores a fresh-bakery texture.
- Keep muffins in a single layer with ½-inch gaps, standing upright. Where muffins touch, contact sides stay cool and steamed while exposed sides crisp unevenly. Large muffins may need sequential batches.
- Add butter and jam after the pull, not before. Pre-applied butter melts off, drips through the rack, and scorches. Use a parchment-paper liner to catch crumbs and drips from blueberry or chocolate-chip varieties for easy clean-up.
