I am cooking various food at home in a new oven that I am kind of stuck with. We're renting and this is the only oven we have at the moment. It has four gas stoves at the top.

The oven is fan assisted but it is a cheap fan and an old grill and oven. Daewoo Cooker DCG5050SI

Basically it burns all my baked dishes. Burns the bottom of the cakes. I always make brownies, cookies and various cakes and no matter what I have tried--the different shelf rack, placing an extra tin. Nothing helps. My cakes always burn at the bottom. What are some tips to prevent this? I've even tried to cut the cake half way or at the end - and ended up with messy food.

    Have you checked with a thermometer to make sure it is baking at the correct temperature?

  • I don't understand the exact problem here. Do you have an oven which 1) simply holds a too hot temperature on both top and bottom when compared to the dial, 2) holds a too hot temperature on the bottom in the relation to top (and does not let you set the temperature of top and bottom separately), or 3) has no top heater at all?

  • An oven thermometer might also be useful for finding out how long the oven can hold heat - maybe doing part of your baking cycle with the oven turned O F F might mitigate the problem. Commented Jan 16, 2016 at 11:15

I'm a person that goes on vacation and bakes bread. As such, I have met a few terrible ovens around the world, and temporarily improved most of them to work better...

Grab a roll of aluminum foil (heavy duty is nice if you have it, or if you don't have any are are buying a roll with this in mind.)

On the bottom oven shelf, come in a few wires from the sidewalls (to allow some air circulation) and crimp on one end of a long sheet of foil - this sheet will be shiny side down, hung below the shelf, and attached to the shelf again in a similar location on the far side of the oven. You'll probably need two sheets (one for the front, one for the back) and should leave a similar small gap at front and back for some circulation, while keeping the centers tight or overlapped.

You can get much of the effect (but not quite as well, or as "semi=permanently") by putting foil, shiny-side down, on the bottom of your baking pans. If either is is not enough by itself, do both. It should help a lot.

    And do not try to cover elements directly with aluminium foil - there are a few questions here dealing with aluminium foil that melted into the elements that way... Commented Jan 16, 2016 at 11:09

I like to make my own pizza but the oven is not so much like the pizza oven in a pizza parlor. My common convection gas oven is too scorchy so I stack two cookie sheets on the rack below the one I'm using. It seems to block the direct rush of scorching heat enough to get more even cooking.
