Keep in mind a great deal of Recipes suggest that you turn the baking item around half way through the baking time... to provide even baking.
Some type of baking stone often makes baking a bit more controlled. A Pizza stone works well or what we've used, a 12" X 12" inch red clay floor tile from Home Depot... helps to reduce the hot spot in the center of the oven by soaking up heat and diffusing the hot spots. Place the stone directly on the floor of the oven... directly above the burner.
