The BEST Chocolate Mug Cake recipe out there!

Seriously though, you’re probably so over mug cakes 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.

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 that is made in a mug!

It’s great because you don’t need to whip out a bunch of tools to make this simple mug cake.

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 recall how it turned out and/or what temperature or time.

This best and moistest chocolate mug cake you will ever have. It's not spongey or dry like other mug cakes! You will never use another chocolate mug cake recipe again!

Course: Dessert
Cuisine: American
Servings: 1
Calories: 606 kcal
  • 1/4 cup all-purpose flour
  • 2 tablespoon unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • 2 tablespoon granulated sugar (you can add 1 tbsp. more if you like it a bit sweeter)
  • 1/8 teaspoon salt
  • 1/4 cup + 1 tbsp. milk
  • 2 tablespoon vegetable oil
  • 1 tablespoon hazelnut chocolate spread or mini chocolate chips
  1. In a medium bowl, whisk together dry ingredients.
  2. Whisk in the milk and vegetable oil until all ingredients are combined and batter has no clumps.
  3. 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.
  4. 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! :)

  5. Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
  6. Microwave mug cake for 70 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
  7. Carefully remove from microwave and enjoy!

Recipe Notes

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.

You can totally omit the tablespoon of chocolate hazelnut spread if you want or use a different spread of your choice (peanut butter, biscoff, etc.) or even chocolate chips like I used in the video. I just thought it made the cake even more moist but the cake itself is moist enough without it!

**This recipe is specifically made for the microwave. I developed it for the microwave. I don't know cook time or temperature for an oven...I'd imagine it'd be a very quick cook time at a low temp., but since I didn't test the recipe for an oven, I cannot give specifics. Sorry!

No eggs? Correct. There are NO EGGS in this recipe. Why? Egg is what makes the mug cake spongy. If you think about it, when you bake a full-sized cake, you typically use 1 or 2 eggs...for a mug cake to use 1 egg is A LOT!

Self-rising flour? I have tested this with self-rising and it does NOT work. At least I felt it didn't work because it was too spongy for me. You are more than welcome to use it, however, please keep in mind that I don't recommend this method.

    This is incredible. I used grape seed oil and I like it the most. I also used white chocolate… but that was deadly. Well done!!

    it’s the best mug cake I have ever had! It stays moist, unlike every other recipe. I used sunflower oil instead of vegetable oil, because I didn’t have the latter. But, mine didn’t rise? Can you think of any reasons why?

      Yes, your baking powder is probably old or you might have overmixed.

    This was the most delicious cake. I don’t cook or bake at all but I was in the mood for chocolate. I found his recipe and followed the directions and the cake came out perfect,it was very-moist. Thanks for sharing 😊

    This cake turned out great, though it took a lot longer in my 700 watt microwave. I cooked it for an additional 30 seconds and still had some soupy batter at the bottom. I plan to make it again and increase the cooking time a bit more.

    I made this today, and it turned out very good! I didn’t have baking powder so I substituted with a little bit of baking soda and vinegar, and it rose well! I also added a little bit of vanilla because I love vanilla. It was very moist. Definitely a recipe to keep!

    Oh my goodness! This was awesome! I used almond milk, applesauce and Enjoy Life mini chips. I’ve always been so disappointed with mug cakes because of the spongey texture but not this one. It was delicious! Thank you!

    Thank you SO MUCH for this great recipe!!! My daughter and I were looking for something quick and delicious to eat (before the bed time….hhh). After some research we’ve found your page and with no doubt decided to prepare your mug cake. I used pure coconut oil, added just a bit of vanilla powder and Nutella. I put it in a microwave for a minute and half. …cake was perfect! Will make it again and again :)))

    I’ve made this before so I know it’s very good, but this time I messed up converting the baking powder (which I currently don’t have) to baking soda. Holy was that a fuck up.
    Make sure that if you are converting, that you put in ¼ of a ¼ tsp—aka just a pinch. And just a small amount of vinegar/lemon juice—add these two at the very end, stir just enough until mixed, then pop it in the microwave.

    Done right, it comes out great. Add too much baking soda because you got the conversion confused, you have a sad bitter mess!
