Tip: If you use a cake pan, you can finely dust the pan with cinnamon (or a dry powder like cocoa or flour) and it will prevent the cake from sticking to the pan without needing baking spray or to grease the pan. Be sure to wait for the cake to cool down after baking so it's firmer, before taking out of the cake pan. This can safely take about 45-60 minutes as steam is trapped inside the moist and fine crumb cake that makes it melt-in-the-mouth good.
