Lemon Mug cake
This Lemon Cake in a mug is incredibly soft, light and fluffy. My family loves this for a quick weeknight dessert when I’m not in the mood to bake. It is quick, easy, single serving and is made without eggs. Mug cakes are handy when you’re not in the mood to bake an entire cake like this Red velvet cake in a cup , Microwave Breakfast Muffin, or banana muffin in a mug.
A delicious no butter single serve dessert that can be enjoyed without a glaze. But, if you wish then simply stir together some confectioners sugar with a dash of fresh juice until smooth and reached the consistency of glaze.
Can I use water instead of milk?
You could, but we highly recommend NOR DOING SO! Milk adds richness (this is a dessert after all) and more flavor when compared to just water.
Use only fresh juice
The only flavoring in the dessert is from fresh lemon juice. So, please do not use the bottled kind.
Can I use lemon extract?
This is a single serve dessert recipe that might become way too lemony when using extract. The juice used adds enough tanginess and flavor. So, there is no need for extract.
How long to cook?
Cooking time depends on the size of mug used. It takes 1 minute + 40 seconds if using a wider mug and 1 minute + 45 seconds if using a narrow mug.
Enjoy HOT
Some MICROWAVE baked cake recipes might get a little dry if left at room temperature for a long period of time. So, we highly recommend enjoying it hot.

Basic baking ingredients like all purpose flour, baking powder, sugar, milk, vegetable oil along with freshly squeezed juice.
