Pour into greased (grease it better than I did) and maybe dusted with cocoa powder- cake pan. I used a 9 inch (I think.. I finger measured). You can use muffin tins too. It was thinner than I had planned. Next time I will double the recipe, or use a smaller/deeper dish.
Bake @ 350 for about 10 minutes. No, really. I looked in and the cake had a volcano growth on one side.. it was done. My oven runs hot.. and it will depend on your pan.. but start checking at 10 minutes.
