Remove the skillet or pan from the oven, making sure to use oven mitts, and cool for 5 minutes on a rack before unmolding.
To unmold, place a serving platter, face-down, on the skillet or pan. Make sure you have your oven mitts on and check by tilting the pan that the cake has loosened from the sides of the skillet. If not, run a knife along the edge.
Now turn the skillet upside-down in a quick motion and tap slighly if needed to loosen the cake. Carefully lift up the skillet.
Spoon any of the gooey, caramel-y juices remaining in the skillet on top of the cake, and enjoy warm or at room temperature.
