Hi Wiljenpake
Is your oven a double oven or single oven? The reason I ask is that I had a lot of issues with my new baking oven due to it being a single oven/larger capacity oven. It took me a while to get used to the shelving and stopping things from burning/scorching and getting things to bake correctly.
Manual - In your new oven manual, you will find a page that tells you what cakes and pastries you can bake. In there, it will say what temperatures to use and what shelf to put it on and approximate cooking time. This will help you going forward.
Thermometer - Even though you think you might be baking at one temperature I found that one of my ovens was 10-20 degrees out so get an oven thermometer to make...
