Notes
Helpful tips
Use a large enough mug - Mug cake will rise significantly while cooking. I recommend using a mug at least 8-10 oz in capacity to prevent the batter from flowing out.
Be careful not to overcook - Overcooked mug cake will turn dry and rubbery. As different microwaves have different power, I recommend checking the mug cake at the 60-second mark, cooking in 10-second bursts if the cake still looks uncooked.
