I have just moved into a new apartment, and am learning the ins and outs of this new oven. But being new to cooking/baking in general, I find that everything comes out burnt, one way or another. Cookies, frozen pizzas, etc.
I find that the bottom of everything I put in the oven winds up burnt to a crisp. The edges wind up overdone and burnt, basically, while the center tends to be slightly undercooked. I am trying to experiment with the times and temperatures, to get it right. However, being inexperienced, I am wondering if my oven just cooks hotter than the temperature I'm setting it to.
For instance, my cookie dough says to cook at 350 in a preheated oven for 10-11 minutes. Cooking to 10 minutes, the center is still undercooked, and the edges are nearly black. (The bottom tends to be all black)
Aside from the obvious "get a thermometer" response, does this seem to show signs of cooking too long (without preheating long enough), or cooking at too high of a temperature?
