Bake for 30 minutes until golden on top and no longer wiggling in the middle when you gently shake the tray from side to side.* (see notes for additional tips on how to check if your blondies are cooked)
Cool completely before removing from the tray and trying to cut into portions (ideally chill overnight in the fridge for best results, or for at least 4 hours in the fridge before attempting to cut them).
