Frequently asked questions
Can you make a mug cake without egg?
Yes. In this recipe I use baking powder to give the cake that light fluffy texture perfect for a chocolate cake. A typical 9 inch cake contains at most 2 eggs, so including an egg in this single serving recipe is not proportional to the amount of cake.
Why is my mug cake chewy?
There are two possible reasons fo a chewy mug cake, too much oil or over cooking the cake. Two tablespoons of oil fits this recipe perfectly. As for over cooking, check the wattage on your microwave and be sure to watch your mug cake as it cooks to prevent over cooking your late night treat!
What do you make mug cake in?
It’s important to check the mug you use for your gooey chocolate cake. Ensure you have a microwave safe mug to cook your single serving chocolate cake. I recommend sticking to a ceramic mug instead of glass mugs as they are able to handle more heat. However, anything microwave safe will work.
