Tip
You could add more than one square of chocolate to the center for an extra gooey version.
Step 4: Microwave the Cake
Place the mug in the microwave and cook for 45 seconds. Check the cake for doneness. If needed, microwave the cake in additional 15-second increments until done. Generally, it should take no more than one minute to cook the cake but maintain a molten center.
