Sometimes you just want dessert and you want it right away! Problem is 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 dessert, and it only takes me about 2 minutes total. 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 really blowing that diet you’ve been on. Of course, if you are really bad (or home alone) this cake can be for just one.  (ummm, wonder how I knew that?)

I had actually taken a video making this, my first try at it, and it’s not as easy as it looks. For one thing, if you are right handed, do not put the camera on the right hand side. I got lots of great pictures of my hands. Bummer, right?!

But the good news is that I got this easy mug cake to curb my sweet tooth. And, if you love lemon, it’s oh so good! Just mix all the dry ingredients in a very large mug, or adapt to 2 smaller mugs where you might have to adjust the cook time down to about 1 minute.

Next add the liquid ingredients, egg and lemon zest. Then stir in lemon curd. I had thought to add it to the center first, like a lemon lava cake, but the curd doesn’t really melt the way chocolate does and it was way better mixed in.

    I’m so sorry I skipped that. I added about 1-2 teaspoons of lemon curd and mixed well. Hope you get a chance to try it.

      I actually made this gluten free with applesauce and no lemon curd. It turned out great! Thanks for updating me. Lemon curd contains dairy

      Sorry 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.

        I’m so happy it turned out so well for you. And that’s a great idea to use applesauce! I’m going to try that myself.

    I 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.

      I 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.

    Love this recipe! I substituted a tablespoon of applesauce and a tablespoon of oil for an egg-free version 🙂
