Directions to Make Chocolate Cake in a Mug

3. Stir until smooth and no dry lumps remain.
4. Fold in chocolate chips if using.

How to Prepare Chocolate Cake in a Mug

Use a large mug to prevent the batter from overflowing while cooking. Mix thoroughly, especially around the bottom of the mug, to avoid pockets of dry flour.

Microwave times vary, so start with 60 seconds and add extra time in 10-second bursts if needed. Overcooking can make the cake dry, so stop once the top looks set but slightly soft in the middle.

For extra indulgence, top with whipped cream, vanilla ice cream, chocolate sauce or crushed biscuits while still warm.
