Hi - I'm new to cake decorating, although I've been baking all sorts of things for years. I'm going to make a 11x15 cake this weekend and was curious about how much longer than the 9x13 cooking time that is on the box do you usually bake a larger sized cake for? Thanks so much.

Here's a link that will help with timing and batter amounts

The Wilton year book is a great resource for things like that. They have a chart for all sizes. For the 11x15 it says to bake at 325 for 35-40 min, 11 cups of batter and approx 8 cups of icing to ice and decorate. Hope that helps.
Oh, or you can just read the post above. 
Silly me
