Since this is a small cake, I suggest you either slice the cake from the pan or use a spoon and eat the cake right out of the pan. This type of cake is easier to remove if a springform pan with removable sides is used. However, you can remove the cake from the baking dish by letting it cool and then inverting it over a plate and the cake should slide right out. If you top the cake with whipped cream or ganache, you won't be able to tell the top of the cake from the bottom.
