When I first came out with my Vegan Chocolate Cake, I didn’t realise how popular it would become! It’s been incredible seeing all your reviews and photos, and it let me know that I will definitely be coming with even more classics. 

You know mug cakes are my thing. For my Vegan Banana Bread, I made my Banana Bread Mug Cake. For my Salted Tahini Chocolate Chip Cookies, I made my tahini chocolate chip mug cake. Now *drum roll please* presenting my Vegan Chocolate Mug Cake! It’s for me, the perfect single size version of my chocolate cake! I can’t count how many times I’ve eaten this (I’ll just say it’s for testing!) so know for sure that you’ll LOVE IT!

What is a mug cake?

In case you don’t know, a mug cake is exactly what it sounds like. A quick single-serving cake that’s usually whipped up in your mug and cooked quickly in it too. It usually takes about a minute to two minutes to make, and the result is a fully cooked, delicious and moist mini cake. I’ve made one before that’s the #1 search result for vegan brownie mug cake, so be sure to check that one out too.

Needless to say – mug cakes are incredibly convenient and so tasty! You usually only want a single serving anyway, and the overall time is always less than 5 minutes to make!Prep shots of chocolate of a mug cake being mixed.

Best tips for making mug cakes

Making a mug cake is pretty much foolproof, but these few tips help to make a big difference. I’ve tested mug cakes over 2 dozen times (yes!), and here are the top tips I took away:

  • Use a wide short-ish mug (like the one in these photos!). If you have a variety to choose from, using this type of mug means the cake rises higher in a concentrated space. I’ve found this helps with cooking.
  • Ensure to stir it all together. Don’t go whisking it for minutes on end, but ensure your entire mug cake is mixed. Since it’s such a small container it can be easy to miss the bottom. Just ensure you incorporate everything. Sometimes I scoop from the bottom up a few times to ensure this. 
  • Adjust your time based on your microwave. The times I’ve provided should work but yours may need an extra 10 seconds. It’ll cook edges to centre so just check the centre that it’s mostly cooked…BUT:
  • BUT, don’t overcook. This will make your mug cake gummy and rubbery and dry. Remember that the mug cake will keep cooking while it’s cooling so it’s better to slightly under bake it.
  • Let it cool for like 3 to 5 minutes before digging in. It really does make a difference, like how you’d let a cake or brownies cool first!
  • I’ve included instructions for baking this in your oven too! 

That’s it friends! Whip this up and enjoy so much!!

Cook Time 1 minute
Total Time 5 minutes
Servings 1 mug cake
Course Desserts
Cuisine American, Universal
Ingredients
  • 1 tablespoon oil any oil of choice
  • 3 tablespoons milk any vegan milk works
  • 2 tablespoons granulated sugar I use cane sugar, you can use brown or coconut too
  • 2 tablespoons unsweetened cocoa powder
  • 3 tablespoons all purpose flour or gluten free flour mix*
  • 1/4 teaspoon baking powder 
  • 1/8 teaspoon sea salt
  • 1/2 teaspoon vanilla extract 
  • 1 tablespoon chocolate chips
Instructions

Instructions

  • In a mug, add in the oil, milk, sugar and cocoa powder. Whisk together for about 15 seconds. Add in the flour, baking powder, sea salt and vanilla extract.
  • Stir to combine for about 30 more seconds to ensure it’s all incorporated, ensuring you get the bottoms too. Add in the chocolate chips and fold in. Feel free to sprinkle some of them on top.
  • Place in your microwave for 65 seconds. It's okay if it's slightly undercooked because it'll continue to cook while it cools. It's better for it to be slightly undercooked than overcooked. Remove and let cool for about 3 to 5 minutes. Trust me!
  • If making in your oven, preheat oven to 350°F/180°C and bake in about a 3.5-inch ramekin (ensure it's oven safe) for 25 minutes. Remove and allow to cool for about 5 minutes. Enjoy!
NOTES
GLUTEN-FREE or REGULAR FLOUR
Yes! You can make this mug cake gluten-free! I tested both and it works beautifully. I tested both regular All-Purpose Flour in a test and Bob’s Red Mill Gluten Free 1-to-1 Baking Flour. 
P.S. I purposefully messed this recipe up (yes, I’m that person) so I could try and troubleshoot. Two notes – whisk in the order provided so you don’t end up over mixing the flours. Also, don’t overcook. The mug cake continues to cook while it’s cooling, so don’t overmix it.
You can use dutch process cocoa or dark cocoa powder, but you'll probably want to increase the sugar by ½ tablespoon.

  1. Hi Jessica,

    I loved your recipe. It was really quick and simple. Being a vegan I’ve always wanted to prepare chocolate mug cake and other cakes on my own and your article has helped me with the recipe. I’ve tried this and I loved it.

    I loved it so much that I’ve featured your recipe in my recent article. Let me know if you would like to check this out. Kudos!

    OMG this was soooo delicious! Best mug cake e v e r.

    Jessica, if I halve the ingredients–should I also halve the Microwave time?

    • Gavin | Jessica in the Kitchen says:

      Hi Steffie yes you should half the time. I would suggest that you use a wider mug if you can as well. Thank you so much for the review.

    This worked perfectly! I was a little worried because my coconut oil was a bit solid when I put everything in the mug BUT I just mixed it well and it was perfect!

    This was the best mug cake I’ve ever made. Usually it comes out gummy but that was not the case of this time. It came out nice and fluffy. I topped mine with strawberries; I will definitely make this again!
