In the mood for dessert? Right away! Just whip up this sweet & slightly tart lemon mug cake. The recipe takes only 4 minutes start to finish & voila – instant dessert!
Sometimes you just want dessert and you want it right away! The problem is that most desserts take a while to either bake or chill, so what does one do when they have this craving for something sweet?
I’ll tell you what I do. I make this easy, “anybody can make this” Lemon Mug Cake dessert. And it takes only 4 minutes start to finish! I mean how can you beat that! Not only that, but it makes enough to split between two people and there are no leftovers to worry about. It’s a great portion control dessert without the reminder of a whole cake sitting on the counter and tempting you for days. Of course, if you are really bad (or home alone) this cake can serve just one. (ummm, wonder how I knew that?)
This mug cake is also dairy-free! Most mug cakes use an egg in their batter but this one is made without any eggs at all. I feel that the addition of an egg makes the cake too spongey. Without the egg, it is still moist and has a cakier texture.
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!
Frequently Asked Questions about Mug Cakes
What is a mug cake?
It is exactly what it says, it’s literally a cake made in a mug.
What is the best container to bake a mug cake in?
Anything microwaveable works – mugs, ceramic ramekins, glasses, jars and even paper cups.
Why doesn’t my mug cake get brown on top like a regular cake?
The brown on a traditional cake is from caused by the caramelization of sugar which occurs at 320 degrees. A microwave usually reaches a high temperature of 212 degrees.
Can I bake this mug cake in a regular oven?
Aside from “why would you want to do that”, yes you can. However. be aware that timing will be affected and a few additional steps should be taken.
Mug cakes cook best in a microwave but the next best thing is a convection oven. It will work in a regular oven as well but make sure that the mug or container is oven-safe.
Next, remember to use an extra tall mug or cake pan and place in a pan with enough water to cover halfway up the mug. Sprinkle a little granulated sugar on top to prevent them from rising too much. This will also add that nice browned top similar to a regular baked cake.

09/16/2017 at 10:14 pmI actually made this gluten free with applesauce and no lemon curd. It turned out great! Thanks for updating me. Lemon curd contains dairy

09/16/2017 at 10:17 pmSorry hit the reply button too quickly! I made this dairy free, gluten free and it turned out great. Lemon curd contains dairy so I would have to make my own but the cake was so good I didn’t miss it.

07/27/2017 at 3:39 pmI tried this and it turned out terrible. I think there was too much liquid so it was rubbery and also eggy. I’ll adjust and try again.

07/27/2017 at 4:37 pmI am so sorry it didn’t turn out for you Danielle. I haven’t heard of any problems from others and have never had any myself. Maybe your microwave is not as powerful so it didn’t cook enough or maybe the egg was too large. You could also try Eleanore’s version as that is egg-free. I hope it works out for you if you try it again.
