- To prep ahead, cover filled ramekins and refrigerate. Batter can be made a day ahead.
- No ramekins? Use a greased muffin pan for 6 slightly smaller cakes; start checking doneness at 6 minutes.
- Invert cakes by placing a heat-safe plate on top, flipping, and carefully lifting off the ramekin.
- Reheat in the microwave for 20-30 seconds, though the center won't be as gooey.
