Chocolate Mug Cake Recipe

This chocolate mug cake is the perfect dessert for one or two people. No leftovers calling you to the fridge!

Over the years, I’ve received a lot of requests for clean eating mug cake. It was never something I grew up with or even heard about until I got into food blogging. But apparently, it’s a thing. So I set out to create this clean eating chocolate mug cake recipe and had to remake it again and again because something about the microwave changes the way the ingredients come together. It was a hard recipe to master at first, but now that I have the hang of it, I’ve made it successfully a few times and I have to say…. it’s DEFINITELY a thing!! Wow!

A fan on Facebook sent me a specific recipe and asked me if I could help her clean it up.

Thinking that this would be yet another mug cake failure, I was not overly enthusiastic about trying it, but figured it was still worth another shot since they come together so quickly.Clean Eating Chocolate Mug Cake Recipe

Persistence is a good thin in the world of mug cakes. Because man, when you get it right, it’s so worth the effort! I would happily enjoy this in place of any birthday cake or any other type of celebration cake. It’s super easy, super fast and super chocolatey delicious. Scouts honor!

It does pack a punch in the caloric department, but as a once in a while treat, it can’t be beat! It’s positively sinful!!


Mug cake is a single serving cake you bake in the microwave in a mug. You don’t want to make this in a different type of cup because it won’t with stand the heat generated by the cake. So you absolutely must have a mug.

Most mug cakes are made in a standard size mug, unless otherwise indicated. You won’t need a giant mug for this. These are meant to be small servings so you don’t have any leftovers.


Sadly, mug cake does not keep well like other cakes. You can certainly put half of this in the fridge overnight, but it won’t be as good in the morning. They tend to harden when they sit for too long. So eat up!

    Could you use a whole egg instead of 2 egg whites?

    1. The Gracious Pantry says:

      Jeannette – Sure!

  2. Laurie Savageau says:

    I just made this and put sliced strawberries on the top!! YUM!!! The texture is different than I expected but the taste is wonderful!! Thank you for the recipe!

    1. The Gracious Pantry says:

      Laurie – My pleasure! Glad you enjoyed it! ๐Ÿ˜€

  3. Just what I needed tonight! Thank you for the recipe. I used whole spelt flour as I find it works well in quick baked goods. I used a whole egg and my cake was a bit chewy. The coconut oil and sugar gave it a nice taste without being overly coconuty. I cooked mine too long, but I will enjoy tweeking that to see what works best in my microwave. Definitely a keeper – so easy AND clean!

    1. The Gracious Pantry says:

      Deana – Fabulous! So glad you enjoyed it! ๐Ÿ˜€

  4. Heather B. says:

    I am going to try this ASAP! ๐Ÿ™‚ It sounds great. I’m still learning how to eat clean and I have been craving chocolate. I’m especially curious to try the coconut sugar. I can’t get used to the bitter aftertaste from stevia. I hope I like coconut sugar because I haven’t found any sugar alternative that I enjoy. Does anyone have any other suggestions of what I can try? Thanks!

    1. The Gracious Pantry says:

      Heather B. – For me personally, coconut sugar has an aftertaste when it’s used in large amounts. But for this, it was fine. If you’re worried about it, try sucanat instead. There’s no aftertaste for that.

  5. I always tend to eat a bit too much than I need, and ive been looking for a healthier option for cake mugs. Though I substituted coconut sugar for normal sugar, used whole wheat plain flour, used macadamia oil and a tiny bit of honey I think my cake turned out well.
    It’s nice knowing even though you’re eating cake that it’s a little bit healthier. Thanks ๐Ÿ™‚

  6. It says two servings ,,,Do you divide into two mugs ?

    1. The Gracious Pantry says:

      Di – You can, but I just cooked it in one mug and divided it. Less dishes…

  7. I don’t have access to white whole wheat flour… how should I adjust he recipe for all purpose flour? And why only use the egg white?

    1. The Gracious Pantry says:

      Ariana – You could use regular whole wheat flour if you want to keep it clean. But it will be a bit more dense when it’s done. If you don’t care about it being clean, then you can simply replace it with regular AP flour. In such small amounts, you should be able to use the same measurements, although I can’t vouch for that completely because I haven’t tried it myself. I used the egg white to cut down on fat content.

    Love this idea! Perfect for a guilt free chocolate fix!

    1. The Gracious Pantry says:

      Eden – Thanks! It sure it! ๐Ÿ™‚

  9. Hi, Tiffany,

    Two nights in a row I made your “Chocolate Mug Cake” (1/2 recipe each night) and both times it was delicious. As a bonus, I added Heath Toffee bits in the mix. Only had regular white flour on hand. The 2nd time (tonight) I nuked it 2:15 vs last night at 2:30. Tonight’s came out nicer. THANK YOU FOR SHARING IT ๐Ÿ™‚

    1. Mayra – Thank you so much! I’m really happy you enjoyed it! Interesting to note the time difference. Thanks again! ๐Ÿ™‚
