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!
It’s a really good recipe when you follow it to the letter. Really moist and soft. Ten out of ten from me.
Really is the best chocolate mug cake recipe. I put that extra tbsp of sugar in, substitute the 1 Tbsp of milk for butter and add 1/2 of vanilla essence. 70 seconds in the microwave. Perfect every time.
Uhmmm pretty gross.
@Melody Harper, I agree. Just made this & I’ve made a ton of mug cakes in my time… Nutella was the only thing that gave it some flavor :(
@Faith, It’s not gross. I’m a teenager and even I know it’s rude to say things like that, even if it’s anonymous. The mug cake I made was good, except that I added a bit too much milk, but even if it wasn’t good you don’t have to say “pretty gross”. Seriously, even my baby brother has better manners.
I made a banana chocolate ice cream to put on top, and it worked together really well! This is an excellent recipe, thank you for sharing it!
Very good mug cake. I put Nutella and chocolate chips in middle, then added lime sherbet on top. Made already good cake the tops.
I love and recommend this so much! It tastes amazing!!!!! So moist and flavorful!
How much salt did you use? 1/8 is a singular pinch of salt.
And that measurement is correct b/c you don’t need that much salt in a mug cake.
By far the best mug cake that I made and yes I tried many recipes.
First time I did a double batch for myself haha. Don’t do that mistake. One batch is more than enough. It’s sweet and delicious.
I am just another lady who can vouch for the amazing recipe that is this chocolate mug cake. 🥰 I tried 4 other mug cake recipes this month, including attempting to finagle my own recipe, but Julie’s version tops them all!
My husband and I shared this on a Friday night with a scoop of vanilla ice cream while watching the Great British Bake Show on Netflix. My husband even timed me making this from start to finish, and I was able to go from zero to a piping hot delicious chocolate cake in FIVE MINUTES (and two seconds) including clean up time. So what are you waiting for? Ready, set, BAKE!
I used 1/4 cup whipping cream because that’s all I had and added a 1/4 cup of water…Delish!!! My microwave needed 120 sec. I’m in an RV using a generator 😁
