How can I turn this into a sheet cake? Will this volume of batter work in a 13 x 9 pan? What temperature and time adjustments are necessary?

A 13x9 pan is quite large and this recipe calls for 2 9 inch round pans. In my opinion this recipe would be fine baked in the sheet pan. If you see the pan is too full just bake a few cupcakes with the excess batter, I do that all the time.
