Hello, My oven typically takes 10 minutes to preheat. After preheating, I pop in a muffin tray and bake for 18 minutes. If I open the oven door and quickly remove the muffin tray and place in another muffin tray to bake a new batch, would I just need to bake for another 18 minutes? Would I need to add more time to the usual 18-min mark? Or, would you recommend to preheat an empty oven all over again after removing the first batch? I'm thinking that a quick swap for the second batch would be fine because it takes 10 minutes to preheat my oven, and the first batch was in the oven for 18 minutes (it's almost like it's been preheating for 18 minutes) What do you think? Thanks in advance.
