A 13 X 9 pan will hold a recipe that calls for 3 8" round pans or 2 9" round pans. We fear that making this whole recipe in one 13 X 9 pan may be a recipe for baking disaster. To avoid that, consider filling the 13 X 9 pan 1/2 to 2/3 full and baking the rest of the batter as cupcakes. Happy Baking for your lucky co-workers. Irene@KAF
