FAQ about blondies in an air fryer

What temperature should I cook blondies at in an air fryer?

Cook blondies at 320 °F (160 °C). The convection air at this temperature cooks the food gently — higher temperatures dry it out or scorch the surface.

How long do blondies take in an air fryer?

Blondies take 20 minutes at 320 °F (160 °C) with no flipping needed. Cook in a single layer for the air to circulate.

Do you need to flip blondies in an air fryer?

No — blondies cook evenly without flipping. The convection air reaches all sides simultaneously. Flipping is only needed for dense or thick foods where one side sits against the basket grate; this food does not benefit from it.

Do you need to preheat the air fryer for blondies?

Preheating is optional for blondies — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.
