The most important piece of advice I can give you is to know your oven! Get an oven thermometer and make sure the internal oven temperature is accurate. Then, as the baking time is nearly over, keep an eye on your cakes. I look to make sure the top of the cake isn’t shiny anymore, that the sides of the cake have just barely pulled away from the pan, and a few moist crumbs come out on the toothpick. Remember it still cooks in the pan as it cools. Your cakes will taste dry if you over bake them even just a few minutes.
