Chocolate Mug Cake

Jump to Recipe

I love chocolate mug cake made in the microwave. It is so simple to make and the cake turns out moist and delightful. Ready in just a few minutes too!

Mug or bowl cakes are so amazing. They are perfect for portion control as well. The cool thing is you can do it with any flavor of cake mix that you want. You only need 3 simple ingredients to make this fabulous chocolate mug cake. Also if you are allergic to eggs or just don’t eat them, that is okay, no eggs required.

Maybe you don’t like cake mixes and want to make it from scratch, I got you covered. You can make it either way.

If I can do it, you can do it. Let’s get started!

Step 1: Gather the ingredients and tools

In order to make this yummy chocolate mug cake you will need just 3 ingredients:

  • Cake Mix – This will work with most cake mixes. (From scratch recipe listed below)
  • Water – I like to use filtered water since my tap water tastes really bad.
  • Oil – A number of different oils will work, vegetable, canola, etc.


  • Mug or bowl (11/12 ounces for normal size)
  • Fork

Step 2: How to make a chocolate mug cake

Whether you are making a mug cake or bowl cake the steps will be the same, it just depends on the size of your bowl or mug. Add the cake mix, water, and oil to the mug and then use a fork to mix the ingredients together.

There you have it, your cake batter is ready to go. Do not follow what it says on the back of the box. Most of the time the cake will call for eggs, but you don’t need them in this!

Step 3: Microwave that cake!

Now it is time to microwave that cake. Place the mug or bowl in the microwave. A small bowl will only take about 1 minute on high. A normal-sized mug will take 1 minute and 30 seconds to 1 minute and 45 seconds on high. This all depends on the wattage of your microwave. If you have multiple mugs or bowls, cook them one at a time.

Once it is done, poke it in the middle with a toothpick, if it comes out clean it is ready to go. The mug and bowl will be hot, let it stand for a few minutes before handling it.

Step 4: Add those toppings to your chocolate mug cake

Once the cakes have cooled. You can top them with whatever you like. Frosting, sprinkles, and powdered sugar are some of my favorites. Or you can certainly just eat them plain. Enjoy!

    I was wondering, can this be made with double the recipe?

  2. 5 stars
    one word, AWESOME!

  3. Looks delicious. Can this be used in a cake pop maker? I have two young nieces and nephews that like cake pops and I want to get them baking but not make a lot.

    Simple recipe, but with awesome flavor. Other recipes reviewed were calling for baking powder, or adding angel food cake mix. But your recipe was dangerously easy…there goes whatever was left of my diet.

    I don’t normally comment on these, but I just had to share how much I love this mug cake! Super simple and the best tasting one I’ve ever had; every other mug cake recipe I’ve tried has left me disappointed, but this actually tasted like real cake! I topped mine with some vanilla ice cream and chocolate syrup, but it was just as good without it when I got to the bottom of the mug! Thank you for this!

    Very easy to make, turned out perfect but needs cream,ice cream,parmasan custard or yogurt. It’s rather dry, I added 1/2 tablespoon cocoa pdr taste terrific and satisfies my sweet craving after dinner.

    I don’t know what happened, I did everything correctly and it tasted bad. And some of the mug cake isn’t even cooked! It also made my house smell like expired beans. some parts were good but the rest was gooey and disgusting.

    • Hello, maybe I can help you figure out what went wrong. Did you check the center of it with a toothpick to see if it was done? If you checked it and it is gooey you just cook it a little longer. There is no reason it should be gooey. It means you didn’t cook it long enough. Times will vary depending on the microwave. What watt microwave do you have?

  10. Very good! My family had German chocolate mug cake this evening.
