Once you have all of your rolls made, place in oven and bake for 25-30 minutes or until golden brown. While they are baking you can mix up the sauce. To keep cornstarch from lumping up, I mix cornstarch with the sugar, then I add it to the sauce, stir sauce until sugar is dissolved, and set aside. Once done, remove rolls from oven, do not turn off the oven. Stir sauce one last time and then pour over rolls.
Place rolls back in the oven and bake until sauce is bubbling and thickened, about 15-20 minutes.
