Difference between a jelly roll pan and a cookie sheet?

Answer 1

The jelly roll pan needs sides that are about 1 in high because many of the recipes calling for a jelly roll pan have a cake-like batter. A jelly roll pan can double as a cookie sheet. Some cookie sheets can double as jelly roll pans.

Answer 2

A jelly roll pan is generally 13" X 9" and has a a 1 inch edge, and a cookies sheet is 13" x 9" but flat (no edge).

Answer 3

I believe a regular cookie sheet is slightly bigger than a jelly roll pan. This will make the cake thinner and it will bake faster so reduce the baking time.
