Step 3: Create the Molten Center

Use a spoon to create a well in the center of the cake batter. Nestle a square of chocolate inside the well and smooth cake batter over top to cover it.

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.
