I have finally found the very best chocolate mug cake recipe. It is loaded with chocolate flavor and has a great fudgy texture. And the best part is that you can make this decadent single-serve dessert in the microwave in one minute!

What is cake in a mug?

It’s the answer to your late night chocolate craving! Mug cakes are a single-serve dessert you cook in a coffee mug in the microwave. It’s like a chocolate lava cake you’d get at a fancy restaurant, but way less time-consuming.

My sweet tooth can get pretty fierce sometimes. Whiny children, long days and most remodeling projects are usually what bring it on. Sometimes I just want a treat and I want it NOW. Can you relate?

That’s where this amazing microwave chocolate mug cake comes in. A few years ago I tested a bunch of different mug cake recipes (read about that HERE).

Most of them were different levels of gross. The recipes that contained eggs were especially weird. The egg made the finished dessert rubbery. Cooking a dessert in the microwave seemed like an impossible dream.


Then I found this chocolate mug cake recipe and it is a true gem. It’s almost like cheating… you get a decadent ooey-gooey treat exploding with chocolatey goodness in less than a minute!

Chocolate Mug Cake

Quickly satisfy your chocolate craving with this easy single-serve chocolate cake in a mug. 

Author: The Craft Patch
  • 2 tablespoons butter
  • 2 tablespoons water
  • 1/4 teaspoon vanilla
  • 1 pinch salt
  • 1/4 cup white sugar
  • 1/4 cup flour
  • 2 tablespoons cocoa powder
  1. Melt the butter in a coffee mug. Add water, vanilla and salt and stir until smooth. Add sugar, cocoa powder and flour and stir until all the lumps are out. Cook in the microwave for 30-40 seconds. If you want less "lava" and more cake you can cook it for 10 seconds more. You may have to adjust the cooking time since all microwaves cook at different speeds.

Recipe Notes

I've noticed a huuuuuuuuge difference in flavor depending on what type of cocoa powder I use. I recently cheaped out and bought a weird off-brand. Major buyer's remorse!! The higher quality good cocoa powder definitely tastes better.

  1. I tried adding 1 teaspoon of inst. coffee and it was a little to strong I think it would have been better with only 1/2 or maybe only a 1/4 o a teaspoon of inst. coffee! but will you try and figure out which is better cause I don't make mug cakes very often so can you?

  2. Just made this and it was DELICIOUS! Super easy and quick to make with basic ingredients that I had on hand. Thanks for sharing! It was just what this pregnant mama needed 😉

  3. So yummy!! I used milk instead of water and a pinch of baking soda. Cooked it a bit too long at 1min, so it was cakey not lava like, but a scoop of ice cream on top and I didn't care as it satisfied my craving in less than 2 min 😊

  4. i microwaved mine for 1 minute and it was perfect lava to cake..
    i also swapped out the water for leftover coffee and topped it with some coarse salt before cooking…
    delicious !!

  5. Just made this. So yummy! I microwaved for closer to 1 minute and it was the perfect consistency. Also may have added chocolate chips. Perfect!

  6. It's really good with two Andes month chocolate things and a quarter teaspoon of peanut butter (it sounds weird but I promise it's good).

  7. Mine probably could've done with 1:30min but even undercooked and squishy it was still good, very dense, only did half the cocoa. Went great with vanilla ice cream.

  8. This turned out terribly for me! The mixture was so dry, definitely didn't have enough moisture, added some milk and still took 2 minutes cooking before it even closely looked near being Cake…

  9. Can I leave out the chocolate for a simple vanilla cake or would that not work? I love the chocolate version I eat it all the time!

  10. Absolutely delicious. I kept mine in the microwave a bit longer and added choc chips and coffee instead of water as per one of the comments. It was moist and decadent. Next time (and there'll be a next time) I'll have with some vanilla ice cream. Shumeaz

  11. This recipe is wonderful! It can be used as a great base for something interesting and fun!

    I melted 1 teaspoon dark chocolate chips with the butter and added another half a teaspoon into the final mix. I topped it off with vanilla ice cream and 3 blueberries.

    I'm sure this recipe will be great on its own too. I will definitely recommend it to people!

  12. This is by far the BEST mug recipe I have made! I added chocolate chips and ate with ice cream. It didn’t even need the chocolate chips. I just added an additional 30 seconds and it was still plenty gooey to my liking. I will keep this recipe for any time I want a quick and easy dessert.

  13. This was the PERFECT reward after tough day! I had to cook it an additional 40 seconds because our microwave is a little temperamental, topped it with some vanilla ice cream and it was the perfect size for my mom and I to split! Thank you for the wonderful recipe! I know it’s going to be a favorite in my entire family!

  14. I've been looking for the perfect chocolate mug recipe, and I think this is it! I did 45 seconds in our microwave, and it was fantastic!

  15. Girl.

    When my kids are finally down for the night and I want something sweet with my Netflix I am NOT interested in sugar free, gluten free, flavor free chocolate cake like the ones I've tried until now.I want something delicious that I'll be paying for on the treadmill in the morning (notice: "paying for," not "regretting"). Thank you for understanding. Thank you! This one's going on my Pinterest board, "tried and true" with a handful of other recipes that actually lived up to the hype and fancy photography.
    You're awesome!

  16. Absolutely deliciously decadent! A few semi-sweet chocolate chips on top and a squirt of redi-whip on top…….OMG! Will try it with coffee in place of water and some ice cream next time….which will have to be a while from now. I could easily eat thhis every day, but I dare not. I would be a blimp in no time!😁

  17. I have cane sugar intolerance, so I used maple syrup instead and it was very yummy! I also used gluten free all purpose flour! It was so delicious!!!

  18. This turned out even better than I thought it would! I did have to microwave mine for the full minute to get it to the right texture. Because I didn’t have chocolate chips, I made my own fudge sauce by boiling a small amount of cocoa, milk and sugar. I’ll definitely be using this again!!

  19. Finally!!! I mug cake recipe that doesn’t have that rubbery texture! Thank you so much for this! Me and my almost 2 year old son are enjoying it so much! He keeps saying, “Bite!”. I might have to make me another one after he goes to bed! Haha

  20. Mmmmm. It was a little too chocolatey for me (yes, that’s a thing in my world.) But the texture was exactly what I was looking for after cooking it longer so it was more cake like vs lava. Definitely saving this recipe so I can make it again with different add-ins! Thanks for a great recipe.

  21. I found this recipe, when I found myself without chocolate in the house. It’s ingredients are what I had on hand, and the promise of fudge lava cake was irresistible! It didn’t disappoint. Rich, creamy, deep chocolate flavor, and the portion size is perfect! I need not try another recipe. I found late night, chocolate heaven in a mug!

    • I haven’t figured out the calorie information. I don’t want to know. Hahaha! But there are multiple websites where you can look up each individual ingredient and do the math for yourself.

  22. Very yummy mug cake and way better than the store bought ones!! I added 20 seconds to cooking time to dry it up a little more. It was delish with a little whipped cream on top. It will definitely be my go to cake when I just need a little something sweet. Thanks for the recipe.
