I've always done baking and cooking in microwave ovens but I don't have any idea of the ovens installed under the cooktops.. Today I'm trying it first time..baking choco lava cakes (funfoods bake mix). On the pack it is mentioned-bake at 200 degrees for 15 mins. There are four rack levels in the oven but I don't know in which one I should bake it. Please help! Thanks a lot!
