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!
Great recipe! Followed it to the letter EXCEPT instead of Nutella I added chopped up marshmallows and sort of poked them under the batter once it was in the mug. I also used a Magic Bullet to mix the batter, which made it even quicker to prepare. It was delicious!
What a great idea to mix it in the magic bullet! I bet it made it fluffier too.
absolutely amazing, moist just as you said. it was a great last minute midnight snack!
I’ve been making this mug cake for a year – never fails! Once you get your microwave timing right, you’ll never want to risk trying another chocolate mug cake again! So many topping varieties – but our favorite is whipped cream and candied pecans.
Delicious! I’ve never tried a mug cake before and just needed something sweet one night and these are all ingredients in the pantry! It really hit the spot. It was rich and moist and I didn’t even use the hazelnut spread. Thanks!
Have made this a couple of times now. First time was by the boom and it was wonderful. The second time I was out of oil and substituted mayonnaise (eggs and oil) and it still came out great. This time I threw a handful of marshmallows at the bottom of the cup first. They rose to the top and I needed a bigger cup but it was great. They did make the cooking time a little longer but it was just like a lava cake but with marshmallows.
Will be trying it with my friends homemade mint syrup next just to experiment. :)
So made this last night when I had a intense chocolate cake craving and it was almost better than really cake! Supper moist and a rich chocolate flavor. I had to substitute a few ingredients because I was out of some. So if anybody is wondering whipping cream and a bit of water substituted for the milk works just fine and a mixture of un sweetened cocoa powder and Hershey’s special dark is still pretty freaking tasty!
Okay so by the sounds of everyone saying it was delicious I had to try it out for myself! Unfortunately, it wasn’t fantastic for me which made me really sad. It looked delicious and promising but the first bite just wasn’t what I was expecting. It wasn’t very sweet or chocolatey which is what I was hoping for. I was so sad! I know I did everything right and my measurements were right as well, but I just don’t know! :( if there is anyway I can make it more chocolatey or sweet please let me know!
Did you see in the recipe that I mentioned to add 1 more tablespoon of sugar if you like it sweeter? If you like things more sweet, add more sugar and to make it more chocolatey, I would add chocolate chips in addition to the hazelnut spread in the middle.
Made this one night for my kids and now – 12 days later – it’s been requested EVERY night since then. Thank you for the great recipe! I’m eating it now – warm with vanilla ice cream. Yum!!!
This has been my go-to chocolate cake for the last 12 months. It literally put me through grad school and the extra pounds were worth it. Today I had it again and I felt the need to come and say Thank You for sharing this delicious recipe. Thank you so much!

I’ve never commented on a recipe post before, but at 2:30 am the night before an exam, this is legitimately the best thing EVER! I sprinkled coffee in there and its amazing! Thank you!
