This easy chocolate mug cake recipe has no eggs and can be made for one or two (if you like to share). It is one of the easiest dessert recipes you’ll ever make and you’ll never make another mug cake again after you try my recipe!
Holy bananas, you guys. This chocolate mug cake recipe is one of your all’s favorite desserts to make. The simplest chocolate dessert yet incredibly moist, easy, and the best single-serving dessert out there (to share or not to share)! Mug cake for one or two and it is eggless and all made in the microwave!
You likely have ALL the ingredients in your pantry already. When you get that late night craving? Or want a small batch dessert (and not whip out a giant baking pan to make brownies to nip that craving)? This chocolate mug cake IS FOR YOU!! If you haven’t made this yet; you are 100% missing out.
What is a mug cake?
I still seem to get this question a lot and a mug cake is literally as it sounds. A cake in a cup! It’s great because you don’t need to whip out a bunch of tools to make this easy chocolate mug cake.
Why is this the BEST Easy Chocolate Mug Cake recipe out there!
Seriously though, you’re probably so over mug cake recipes and you’re probably rolling your eyes at me right now but STOP! I promise you this isn’t like any other mug cake out there. I’ve tried a bunch of mug cakes and I hated them.
I thought they were a really neat concept for a quick dessert fix but nothing would ever beat baking an entire cake or cupcake. I hated that all the mug cakes came out SPONGY and they had the grossest texture.
Last week, I was CRAVING chocolate like none other. It was a pretty dire situation. We didn’t have any desserts in the house because I hadn’t been baking and I didn’t want to run out to get anything so I thought I’d give a mug cake a shot.
It ended up turning into a recipe development hour because the first batch came out horrible. Like, I threw it in the trash can and it was just one lumpy sponge thing.
The second one was slightly better but still really bad. The third, I switched out some ingredients and added a little bit more of some and it came out how I wanted but I knew it could’ve been better so on the fourth try, I finally got it to work and the exact texture I wanted.
Ingredients you’ll need
For the exact measurements, please scroll down to the recipe card.
- All-purpose flour
- Unsweetened cocoa powder
- Baking powder – make sure to check the “best by” date for this. It’s an important factor.
- Sugar
- Salt
- Milk
- Oil
- Chocolate hazelnut spread
Substitutions and variations
- You can use dark cocoa powder if you desire but I actually have a dark chocolate mug cake recipe for that!
- I’ve heard of so many variations that folks have used for the chocolate hazelnut spread. Here are a few ideas:
- Mini chocolate chips
- Lindt truffle in the center
- Mini M&M’s or your favorite mini candy bar
- Caramel sauce
How to make chocolate mug cake
For complete instructions, visit the recipe card below.
Whisk together dry ingredients. In a small bowl, whisk together the dry ingredients.
Add the liquids. Next, add the liquids into the bowl and whisk until a batter-like consistency forms and there are no remaining dry ingredient lumps.
Pour into a mug. As it’s a microwave mug cake, make sure you are pouring the batter into a microwave-safe mug!
Time for add-ins! If you’re using the chocolate hazelnut spread, go ahead and add that right into the center! Same for other add-ins. You don’t have to push it down, the batter will cook around it and sink it down.
Microwave! Time cook it! Place the mug in the microwave and cook for 70 seconds (please see important notes below).
Tips for success
- Please note that ALL microwaves are different therefore can yield different results and can overcook this mug cake if you aren’t careful. My microwave is 950 watts and I cooked mine on 100% power for 70 seconds*. Knowing this information, it may help you better judge how long to cook yours for and at what power.
- Mug size makes a huge difference! If you’re using a larger mug that is taller then it will take longer to cook. If you’re using a larger but wider mug, it may take less time to cook. There isn’t a one size fits all for this, sadly. The cooking time is a general cook time that works best for most. Unfortunately, there are so many factors that can contribute to your particular mug cake.
Common questions
This chocolate mug cake is made without eggs. Why?
Okay, I get asked this a lot too and the reason why this mug cake is made without any eggs is because that is what makes it have a spongey texture!
If you think about it, it makes sense. Why would you put an entire egg into a mug cake when a regular full-sized cake often asks for one or two eggs? This isn’t a full-sized cake. And of course I’m not going to ask you to divide an egg in half. Just omit it! Best texture, ever!
Can I make this with self-raising flour?
You can, but I tested it with self-raising flour and it just came out spongey and not the texture I wanted.
I like my cakes light, fluffy, and moist and with the self-raising flour, it just didn’t yield the results I wanted.
There have been many people who have used self-raising flour in this recipe and didn’t notice a difference so if you’re up for the challenge, I say go for it.
Can this mug cake be made in the oven?
No, this was solely developed for the microwave. I have had readers who have baked this but I honestly don’t recall how it turned out and/or what temperature or time.

The Best Chocolate Mug Cake
Ingredients
- ¼ cup (31 g) all-purpose flour
- 2 tablespoon unsweetened cocoa powder
- ¼ teaspoon baking powder
- 2 tablespoon granulated sugar, (you can add 1 tbsp. more if you like it a bit sweeter)
- ⅛ teaspoon kosher salt
- ¼ cup (59 ml) + 1 tbsp. milk
- 2 tablespoon vegetable oil
- 1 tablespoon hazelnut chocolate spread or mini chocolate chips
Instructions
- In a medium bowl, whisk together dry ingredients.1/4 cup (31 g) all-purpose flour, 2 tablespoon unsweetened cocoa powder, 1/4 teaspoon (¼ teaspoon) baking powder, 2 tablespoon granulated sugar, 1/8 teaspoon (⅛ teaspoon) kosher salt
- Whisk in the milk and vegetable oil until all ingredients are combined and batter has no clumps.1/4 cup (59 ml) + 1 tbsp. milk, 2 tablespoon vegetable oil
- Pour batter into a microwave-safe mug. Mine was a 14-ounce mug. You want enough head space for the cake to rise without pouring over.
- Add hazelnut chocolate spread in the middle of the batter or mini chocolate chips. Just drop it in the middle, no need to push it down and sink it in the batter. It does that on its own when it cooks! :)1 tablespoon hazelnut chocolate spread or mini chocolate chips
- Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
- Microwave mug cake for 70 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
- Carefully remove from microwave and enjoy!
So, I got these 3 little 4” cake pans. I needed a recipe to make a mini layer cake and used this. I made the 3x amount and it was just right. I baked them in a toaster oven at 350 deg F at 17 minutes and they were perfect. They were a good consistency and easy to cut to get the rounded top off for the layers.
Okay I just tried this and am amazed that I have a little cake in less than 5 minutes! A couple minutes to gather and measure the ingredients and then 70 seconds in the microwave (my microwave is super strong). The texture is so light and fluffy!
I made couple substitutions because I didn’t have milk on hand and only oatmilk coffee creamer haha, so I used that and omitted the sugar since my creamer is sweet. Even with me messing with the recipe, it turned out great so I can’t wait to try this again with regular milk and sugar!
The best!!!! All I needed was a little something sweet. This recipe fit the bill. I had everything needed to make this little mug cake. After five minutes prep and 80 seconds in the microwave I was in heaven. I have tried other mug cake recipes but none came close to this one. Moist and full of flavor. Thank you for posting.
Amazing! Would definitely eat again. The chocolate chips went down perfectly so they were in every bite. I had made while it was snowing & I felt like cactus; so warm but perfectly moist. Thank you, Julie.
@Sophia W. Jones, like cactus???
@Megan, I’m guessing Sophia could be from Australia, saying you feel ‘cactus’ is common slang here! It means you feel like s*#t 😂
I have made this 3 times and overcooked it each time but the last. The bold claims of the moistness of this cake is true if you cook it for the right amount of time. Hands down the best mug cake I’ve tasted and probably will ever taste. Thank you so much for this recipe!!!
I was sat here working and craving something sweet, googled mug cake and chose this one. So good. Fair point about the eggs, you don’t need them. Didn’t have cocoa powder so used cadburys option, which worked. 10 minutes later I am a happy camper (that included eating it). Pinch of salt in genius.
This is a keeper of a recipe
I forgot to vote with my comment but it’s an easy 5 stars from me
I’ve made this recipe countless times over the years since i’ve found and and it’s never done me wrong, meeting the criteria of not too sweet, not too rich while being chocolatey (a difficult balance that i sometimes fail, but always always due to the nutella I add…sometimes i’m too generous).
Today i made it again for the first time in a year or two and was wayyy too overconfident for 2am cravings so i eyeballed the measurements, used my usual substitutions, and added a little too much baking powder…
when i mixed in the liquid ingredients i realized i’ve done terribly wrong as the consistency was more dough-like than i recalled so tried to aim for the proper consistency with more liquid ingredients, upped the cooking time, and prayed for the best.
You know what? It held up. It’s pretty close to the original i think of fondly, and the texture pretty good even though i nearly botched it irreparably. This experience gave me a whole new level of respect for this recipe and it’s author because it’s so reliable and forgiving of mistakes. Pair this with strawberry preserves instead of dark chocolate and it tastes phenomenal.
A great mug cake to cure those cravings on a Friday night! The individual portion is great for sharing and no worries of leftovers. Soooo good!
Great! After It got dry it had the texture of a brownie. Good recipe.
