Do you bake 2 apple pies longer than if were to one?

Baking two apple pies will require slightly more time than baking a single apple pie, but not twice the amount of time. The increased baking time is due to the fact that there is more filling in two pies, which takes longer to heat through and cook. Additionally, the oven may take longer to come back up to temperature after opening the door to insert the second pie.

As a general guideline, you can add approximately 10-15 minutes to the baking time for two pies compared to a single pie. However, it's always best to check the doneness of the pies by testing with a toothpick or knife inserted into the center of the filling. The pie is done when the toothpick comes out clean or with just a few moist crumbs attached.
