How do I recognize if a dish cannot be cooked in a gas oven? I have moved to a house that has a gas oven. I am new to gas ovens. What dishes can we cook in a gas oven? Cake? Are cookies possible to bake in a gas oven?
You can cook anything in a gas oven that you can cook in an electric oven.  There might be a little extra moisture (due to the products of combustion), but some people consider that to be an advantage when baking bread and cooking roasts.
