As I settle back into reality, I’ve been trying to take things easy in order to maintain the relaxation glow from vacation for as long as possible.

I originally wanted to make another dessert, but I ended up going with something simpler – a chocolate mug cake. Two mugs, minimal cleanup, ready in about 5 minutes.

I’ve made mug cakes before, a Nutella version. This time I decided to try just a regular chocolate cake. I worried that the batter would be too dry. The Nutella version has always been moist, so I added a little more oil and milk to compensate.

  • All-purpose flour
  • Granulated sugar
  • Baking powder
  • Egg
  • Unsweetened cocoa powder
  • Milk
  • Vanilla extract
  • Oil

How to Make It

This recipe is enough for two mug cakes. Mix all of the ingredients in one large mug and then transfer half the batter to another mug.

Cook the mug cakes one at a time. Start by cooking one on high for one minute and then check if it’s done. If it’s not, cook it for 30 seconds longer and check it again.

Be careful not to overcook the cake or it will be rubbery. While the first ones cools, cook the second one. I think they taste best warm.

The cakes didn’t rise as much as my Nutella version did. I think next time I’ll add some more baking powder. These cakes were cooked in just a little over a minute. They tasted best while still warm. It was a perfect treat to end my night.

You only need two mugs, five minutes, and a few simple ingredients for these easy chocolate cakes.

  1. Just curious if you think swapping out the cocoa and vanilla for matcha green tea powder is do-able.

    I’ve made this recipe, doubled, in two 18oz stoneware mugs–which it more than filled when baked (no doubling next time!). A recent overseas trip left us with more matcha green tea powder than we know what to do with, so I’ve also made your microwave matcha mochi cups; they were fantastic. I immediately used the rest of the Mochiko making eight dozen matcha mochi cupcakes.

    I still have green tea powder I want to use, but my husband has asked for a rest on the glutinous rice flour because it’s so hard to resist the cupcakes. So is this a possible compromise?

    • unfortunately a direct swap wont work because of how strong matcha powder is, you wouldn’t need as much and you will also need to adjust some of the other ingredients. I know a matcha cake is possible in the microwave, but I wouldn’t start with this recipe base for it. Instead I’d start with one of my white cake mug cake bases and add maybe a 1 tsp of matcha powder to it.

  2. I just made the chocolate one. It was quite good. I substituted splenda & egg substitute, used dark Hershey’s cocoa powder and they were moist. Thanks for the recipe.

  3. Thanks for the recipe! I just made the chocolate mug cake but I only had sweet cocoa powder. I ended up just using 2 tablespoons of sugar and it came out delicious! I guess I had some really big mugs because when I split it in two it made two little 1 1/2 inch tall cakes. I ate both as soon as they were cool! 1 minute made them perfect- just moist enough! Love your recipes!

  4. I just tried out your Chocolate Mug Cake and it turned out great! Can’t wait to try your other versions of mug cake. One question – if I can’t finish the batter, can I keep it in the fridge for another day? Thanks for putting the time & effort to experiment with the recipes and then sharing with your readers!

  5. These are boss! I added some Reddi-Whip on top and they were awesome! Thanks for the recipe

  6. I liked that cake I just ate some

  7. i have only self rising flour. would that work as well?

    • Actually self rising flour already has rising agents in it so you can’t just substitute regular flour for self rising. I’m not sure exactly how you would need to adjust the recipe to make it work. I would have to fiddle with it and try it out, but you would definitely have to remove the baking powder from the recipe.

  8. Only when really desperate…

  9. Adding some chocolate chips would be yummy (:

  10. I just had this for breakfast and made some slight alterations for it to be a bit healthier. I substituted the flour for cooking oats, used a natural sweetener (stevia) to replace the sugar and instead of oil and milk I used fat free yogurt. It was pretty good, but I’ll try your original recipe soon too! thanks so much for sharing, I had the strawberry mug cake last week and am slowly getting hooked on these things.. have a great day 🙂

  11. The cake was slightly dry (but still delicious for being done in less than 2 minutes), so I added my own twist. I melted a large spoonful of peanut butter in a separate bowl for 20-25 seconds, and then added 4 marshmallows and continued to heat the peanut butter with the marshmallows until the marshmallows doubled in size. Then I mixed it all together and drizzled it on top of the finished cake. Perfection!

    • Your twist sounds really good! I agree the chocolate mug cake is slightly dry on it’s own. It’s definitely not my favorite mug cake of all the ones I tried. The Nutella mixed with chocolate is more moist, and the brownie mug cake is even better.

  12. Hi Kirbie, thanks for this recipe, it is legit! Question: If I prepped the batter tonight, can I store half of it in the fridge and heat it up tomorrow evening for dessert?

    • Hi Kathleen. Unfortunately I don’t know the answer to that question. I’ve never tried it. If you do try it, let me know! Thanks

  13. I am definitely trying this tonight! Looks so delish 🙂 love your blog!

    • I love making this when I’m craving a homemade dessert and I’m too tired to cook or wash a bunch of dishes. I hope you enjoy it too!

  14. the cakes came out really well! the girls loved making it. we love nutella but i wasn’t sure the neighborgirls did or had any nut allergies. one minute in the microwave turned out to be just right.

    the pizza puffs came out so good that we made another batch! next time i want to use a stronger flavored pepporoni (i used a cheapy one for the kids) – like peppered salami or something.

    also, instead of using non stick cooking spray on the mini muffin tins, the girls melted butter and brushed it on the tins. it smelled so good while baking but it made a light brownish outside crust.

    • Oh peppered salami sounds good. And I’m glad the chocolate mug cakes came out well! sometimes people overcook it and it becomes inedible. Melted butter on the pan sounds good. I’ll have to try that sometime.

  15. thanks Kirbie re: cocoa powder

    also we do have Nutella. I’m not sure the girls like it though. they can do the regular recipe and my husband and i can make the nutella one.

  16. Ooh, I like how simple this one is! It’s kid friendly too. Today I’m going to have my daughter and the neighbor girls do your pepperoni pizza puffs recipe. i might have them do this too!

    btw, i only have unsweetened cocoa powder. would that be ok for this recipe or must it be sweetened?

  17. Looks like a great last-minute dessert for one!
