- Let the brownies cool completely before cutting to achieve clean edges.
- If you like extra crunch, sprinkle a handful of sea salt on top before air‑frying.
Troubleshooting
Brownies are dry and cakey.
Do not overmix the batter and reduce cooking time by a few minutes.
Brownies are undercooked in the center.
Add 2‑3 more minutes of air‑frying; ensure the air fryer temperature is accurate.
Chocolate seizes when melting.
Microwave in short bursts, stirring each time, and add a teaspoon of butter if needed.
Storage
Refrigerator: Store in an airtight container for up to 5 days.
Freezer: Freeze individual squares wrapped in plastic and then foil for up to 2 months.
Room temperature: Can sit at room temperature for 1 day, but texture is best when chilled.
Make-Ahead Tips
- Bake the brownies a day ahead and store sealed; they taste even fudgier after resting.
- Freeze baked brownies and reheat in the microwave for 10‑15 seconds before serving.
