Looking for a chocolate mug cake, no egg? I gotchu.
These are crazy times we're living in, and the last thing you need is a craving for a food you are physically unable to procure. It's one thing to have a craving and feel too lazy to run to the store, but it's quite another to know you can't venture out to get it for one reason or another.
One of the things I crave pretty frequently is chocolate cake. But the idea of baking an entire chocolate cake for a brief moment of omg I need chocolate right now because my sweet tooth is insane feels pretty silly and unnecessary.
However, if you decide that needing to make a chocolate layer cake is not silly and unnecessary, here's my favorite chocolate cake recipe for future reference.
So then sometimes that leads you to just run to the store and buy a small pre-made chocolate cake to get it out of your system (or I guess, into your system). But what about when you can't for… reasons?
Is not being able to go buy a cake the end of the world? No, of course not. But it's just one more thing added to the list of things that could be stressing you out, and you don't need or deserve that.
If you're unable to go to the store, don't have time, or don't have all the supplies you need to kick your chocolate craving… this moist, easy chocolate microwave mug cake recipe is here for you.
What is a mug cake?
This is the easiest question I'll answer all week: It's a cake made in a mug, in the microwave. No mixer, no oven, and no frosting.
And in the case of this chocolate mug cake – no egg! Also, no butter.
You can use a fork to mix everything together right in the mug itself, but I tend to make a mess that way – so I mix everything in a small mixing bowl first, then pour the cake batter into the mug.
Can you bake mug cake in an oven?
Short answer: Nope.
Longer answer: This recipe is specifically designed to be made in a mug, in the microwave, without eggs. Eggs are traditionally used in cakes to act as a binding agent, but in the case of a mug cake, you don't need to worry about it producing a certain shape and keeping it. You zap it in the microwave and then just dig in! It won't last long enough for the shape or appearance to matter.
So… chocolate mug cake, no egg = no baking in the oven. I repeat… do not put your mug cake in the oven, friend!
Want something with a difficulty level somewhere in the middle? Try my chocolate depression cake – you only need one bowl!
Do I need a special mug?
Yes and no. You do want a microwavable mug that's big enough to hold the cake once it's cooked, so you want at least a 14-ounce mug. You can probably get away with a 12-ounce mug, but keep an eye on it.
Also, try not to use one that's tall and skinny because you might end up with an unevenly cooked finished product.
Fillings and toppings for your cake in a mug
- I find that a tablespoon of Nutella, peanut butter, or other creamy filling dropped into the center of the mug just before microwaving gives this cake a super moist, irresistible flavor. It's necessary for the moisture you're looking for.
- Also, I'm a big fan of adding a handful of chocolate chips to the cake batter because… chocolate. I really like chocolate. That's really the only reason, and I think it's a solid one.
- I'm also a big fan of a little pinch of cinnamon, and sometimes even a little chili powder. Mix it up and make it your own!
- It doesn't need toppings, but why not add some anyway? Top your freshly cooked mug cake with a scoop of ice cream, whipped cream, sprinkles, and a cherry. Because you deserve it.
Mug cake substitutions and variations
- Milk: You don't have to use dairy milk, so feel free to use a non-dairy alternative like almond milk, oat milk, soy milk, macadamia milk, etc. I've even used chocolate milk and it added a little somethin' somethin' – just saying.
- Oil: I like to use refined coconut oil, but you can use whatever your preference is. If you want to add a little different flavor, you could use unrefined coconut oil (since that has a stronger coconut flavor), vegetable oil, coconut oil, grapeseed oil, etc.
- Light brown sugar: We're making this mug cake with brown sugar, but feel free to use coconut sugar instead. I don't recommend granulated sugar because it changes the depth of flavor and gives it a bit different texture.
- Vanilla extract: Mix things up and add or swap a different extract flavor! Almond extract works well, or you could add a little peppermint extract for the holiday season. Just note that some extracts are much more potent than others (peppermint, for example), so you may only want to add a drop of those so that it's not overpowering.
- Cocoa powder: I call for unsweetened cocoa powder, but you could swap it for some Special Dark cocoa powder, or even raw cacao powder (aff link). I don't recommend Dutch-processed cocoa powder because it's a little too bitter for the end result, IMO.
- Nutella or peanut butter: This is my little secret weapon that gives this mug cake more flavor and moisture. You could swap them for another kind of chocolate hazelnut spread, almond butter, cashew butter, chocolate sunflower butter, etc. You can also omit it if you'd like, but note that your end result will be less flavorful and moist.
- Chocolate chips: I adore the little pockets of melty chocolate in mine, so I can't imagine making my mug cake without them – but you can if you want! You don't know what you're missing though ;)

FAQs
It's a cake made in a mug, in the microwave. No mixer, no oven, and no frosting. And in the case of this chocolate mug cake – no egg! Also, no butter.
Nope. This recipe is specifically designed to be made in a mug, in the microwave, without eggs. Eggs are traditionally used in cakes to act as a binding agent, but in the case of a mug cake, you don't need to worry about it producing a certain shape and keeping it.
You combine all the ingredients in the recipe card in a microwave-safe mug (or a small bowl, and transfer to the mug), drop a tablespoon of Nutella or peanut butter in the middle, and then microwave for 65 seconds.
Yes! You want it to be cooked, but still moist and a little gooey in the middle. When you eat each spoonful, the textures will combine for the perfect moist bites.
This is usually because the cake was overcooked, but it could also be because there was too much oil added.

is there any substitutions to the all purpose flour?
I realize I can test this myself, but you might be able to answer this before I am able to: is it okay to add an egg, or does that throw things off?
If you put an egg to cook in a microwave it will remain raw and can put your health in danger
Me and my sister used this recipe to make this mug cake, it was so fun to make + it was so DELICIOUS. It is better than drinking anything in a mug.
Thanks for the recipe!!!
THIS TASTES INCREDIBLE, I’ve tried other ones they tasted so bad. I would give this 100/10. I didn’t have Nutella or peanut butter but it still tasted AMAZING, with ice cream it tastes even better. Thank you for this recipe!!!
made this on a whim. wanted something chocolatey, and ended up finding this recipe. its so delicious and moist!! the cake is perfect if you just want a snack on the go. its good with a nice glass of milk too!
Ahh I love to hear this! Thanks so much for coming back to share your experience.
Nice
So good! I only made one change – I used mayo instead of oil. Super tender and cooked perfectly! Will definitely make this again!
rich, decadent, most… This mug cake us better than most “real” cakes.
thanks for the new go-to dessert!
Oh my goodness, what a compliment! Thank you!
LOVE this recipe! I’ve tried mug cakes before and this is my absolute favorite. Moist, light, fluffy and so so good! Definitely saving to make again and again.
Thank you so much for the kind words, I’m so glad you enjoy it!
it’s really nice I like to have this as a treat breakfast once a week. But am I the only one who things that to make this in 5 mins is a bit unrealistic? Because u need to weigh out all the ingredients, them put them into a bowl and mix, then u need to put it in the microwave. I’m not complaining but this takes je at least 30 mins. Maybe it’s just me tho
I always bake my cakes but this time i was craving for a quick chocolate cake and i wanted to try this recipe, it turned out soooooo good!!! Really soft, moist and the Nutella in the middle was so yum!!!
I’m so glad you liked it – thanks so much for coming back to share your experience!
I didn’t put any peanut butter or nutella in it and it still tastes AMAZING!!! Probably the best chocolate mug cake I’ve made so far!
I’m so glad you liked it!
I meant to leave a star rating on my comment
I’ve made this so many times now, I love using Nutella and chocolate ice cream on top!
If using peanut butter, when do you add the choc chips?
Right after the peanut butter!
doesn’t work with almond flour
Hi Isabella, thanks for your comment – the recipe calls for all purpose flour, and as you stated would not work with almond flour as that does not contain the same binding qualities necessary for this recipe, nor would it be suitable as a 1:1 replacement for all purpose flour.
If you’d like to learn more about the different types of flours and how they can be used, I’d suggest checking out my post about Flour 101: https://stressbaking.com/flour-101/
Best mug cake!! I didn’t have chocolate chips or Nutella, so I put in 1 Lindt chocolate ball!!! Amazing thank you!
OhmyGOD that sounds freaking amazing! I’m totally going out to buy some and try that myself!
It was very quick and easy to make also so YUMMY! I made it for all of my sisters and we loved it.
I’m so glad!
Ive made this twice. I liked it the first time, but I like my desserts super sweet (which is probably a bad thing LOL) so I added an extra tablesppoon of brown sugar the second time. Turned out great for my sweet tooth last night!
Happy to hear it! I know I err on the side of less sweet (I prefer more dark chocolate flavors, black coffee, etc.) so I’m glad that little adjustment made it more to your liking :)
Meant to take a picture, but we ate it all first! Ive tried a handful of mug cake recipes, and this one is perfect. Used peanut butter instead of nutella. Our bellies are warm, and happy! Thank you!
Nothing like a happy belly – I’m so glad you liked it! Thank you so much for coming back to leave a comment and rating, it’s greatly appreciated <3
This is truly a keeper. We loved it. I made it in my medium Pyrex and doubled the recipe. Turned out perfect.
I’m so glad that you liked it! Thanks for coming back to leave a comment.
