How many boxes of cake mix required for a jelly roll pan?
I just made a strawberry cake roll yesterday, and my Duncan Hines box made 2 rolls, I did discover, at least with the strawberry, that perhaps you’ll want to add an extra egg or 2, this should add some springiness to the cake so that they won’t crack when you roll them up. Be sure to generously grease and flour your roll pan, or use parchment paper to keep the rolls from sticking when you turn them out. Good luck.
