Tips, Variations & Serving Ideas
How to get the perfect molten center every time
Use a solid chunk of good chocolate—dark or semisweet works best. Don’t overmix the batter. Adjust microwave time based on your microwave’s wattage. Under-cooking slightly helps preserve that gooey center.
Creative twists & adaptations
Try sugar substitutes or almond flour for dietary changes. Experiment with toppings like whipped cream, fruit, or sea salt. A dollop of nut butter in the middle can give it a surprise inside twist too.
Frequently Asked Questions
What kind of mug should I use?
Use a microwave‑safe ceramic or glass mug that’s big enough to prevent overflow as the batter rises.
How do I know when the cake is done?
The top should be set but shiny; the sides cooked. Gently touch the surface—it should spring back lightly but still feel soft in the center.
Can I make this ahead or store leftovers?
It’s best eaten fresh. You can store it for a short time and reheat, but the molten center may solidify.
Can I change the ingredients for dietary needs?
Yes! Gluten‑free flour, dairy‑free milk, sugar substitutes, and egg alternatives all work with a few adjustments. Just monitor the cooking time carefully.
