"Bake jumbo cakes for 25 minutes. Bake regular cakes for 20 minutes. If you choose to make a large cake, bake for 22-25 minutes in a 10 inch cast iron skillet. The cake is done with a toothpick inserted in the middle comes out clean. Remove from the oven. Let cool in pan for 3 minutes. Run a knife around the edge of each cake to help loosen in case it sticks a little. Place a wire cooling rack on top, and quickly flip over on top of sheet tray to catch extra drippings. *Note-this is not an original recipe, I found it via Pinterest and http://www.bigmamashomekitchen.com..."
