⁉️ FAQ
Do you have questions about this recipe? Here are the answers to the most commonly asked questions.
It’s hard to believe, but a mug cake is a cake in a mug. Using a fraction of the ingredients in the correct proportions, mug cakes taste just like regular cakes because they are regular cakes.
It’s always best to use at least a 6—to 8-ounce mug. The larger, the better. Mug cakes rise and can overflow from a smaller mug.
Rubbery mug cakes are usually the result of overmixing the batter, which is easy to do with such a small amount. When mixing mug cake batter, be sure to only mix until everything is combined.
In baking, just combined means mixing the wet and dry ingredients until the dry ingredients are moistened. The batter will usually be lumpy, but that’s okay!
