Simple! Lower temperature! If the item calls for 350 degrees, we bake it at 320-325. Bottom does not burn, and bakes even. We never push the temperature to the recommended cooking temperature as the oven appears to run hotter. We've never calibrated the oven, but 25-30 degrees lower than the setting on the knob works very will. We've experimented with a lot of biscuits. Once we got them to cook even, we started doing the same with cakes, pastries, everything, and this seems to be the solution. No stone ware, no gimmicks, no hot spots, no uneven cooking. Works for us.
