Remove from oven and let sit for a few minutes. When they have cooled a little , you can turn them out on a plate. If you are planning to eat them later, you can let them cool completely and then wrap them individually and freeze or refrigerate until you need them. To serve, warm them up in the microwave for a few seconds to make the lava molten again. If they are frozen, this takes about 15-20 seconds. Don’t over microwave or the cake will become rubbery.You can also warm them up in a 350 degree oven for 5-10 minutes.
