Recipe Notes

Tips for Making the Best Mug Cakes

PRO-TIP: Make sure to use a large enough mug so there is no overflow to mess up your microwave. The mug should only be half full prior to baking.


To check for doneness, just touch the top, It should be firm and bounce back slightly. If it appears doughy put back in microwave for another 5-10 seconds.


Know that your mug cake will sink after it is taken out of the oven. It is supposed to do that!


Your mug cake will not be brown on top like a regular oven-baked cake. The brown on a traditional cake is caused by the caramelization of sugar which occurs at 320 degrees. A microwave reaches a nigh temperature of only 212 degrees.
