What is this? Another mug cake?

Can you FEEL how addicted I am to these? They are like your own personal dessert, and no one needs to know that you made it! One quick wash of a cup, and all the evidence of your broken diet, vow to not eat chocolate, whatever is gone!

If you were to ask me which of the mug cakes that I have made recently is my favorite, I would have to say this one. Hands down. Maybe the peanut butter mug cake comes in a close second, but this one I'd say is pretty perfect.

And after a grueling week, you deserve it!

Key Ingredients

All the ingredients you need to make One Minute Chocolate Mug Cake laid out on a marble surface.
  • unsweetened cocoa powder: this creates that rich chocolate flavor you are looking for.
  • all purpose flour: gives the cake the structure so that it holds together.
  • pinch of salt: enhances the overall flavor, and balances out the sweetness.
  • white sugar: sweetens the cake, and offsets the bitterness of the cocoa powder.
  • baking powder: allows the eggless cake to rise quickly in the microwave.
  • neutral oil: adds the essential moisture to make sure the cake ends up being soft and fluffy rather than dry.
  • milk: to hydrate all of the dry ingredients and creates a smooth, pourable batter.
  • small splash of vanilla extract: adds depth to the overall chocolate flavor.

Step 2: Mix in the oil, milk and vanilla extract until fully combined. Microwave for 30 seconds and check if it is done. If it isn't, microwave for 10 second intervals until the cake is done.

One Minute Chocolate Mug Cake Expert Tips

To make this mug cake vegan: all you need to do is use a non-dairy milk in place of the whole milk. I suggest either coconut milk or oat milk to maintain the same fluffy cake texture, but I have used both soy milk and almond milk with success.

Make sure you keep an eye on your microwave mug cake while cooking. Depending upon the size of your microwave-safe mug, it may be prone to spilling out of the top of the mug while it's cooking. I recommend a large coffee mug for this recipe, but if you have a smaller mug it will boil over in your microwave oven. Also, different microwaves cook things differently. Take note of how long it takes for the cake to cook, and if it starts to overflow stop the microwave then restart it again after a couple of seconds. The next time, you will know how long it will take to cook.

Add in your favorite mix-ins. ​I love adding in chocolate chips, but fresh fruit or nuts work well too! I like adding half the toppings halfway through so they don't sink to the bottom of the mug.

Top it with your favorite toppings. ​This mini chocolate cake pairs so well with a scoop of ice cream, or chocolate frosting. But you could also top it with chocolate hazelnut spread, whipped cream or whatever else you have on hand.

Frequently Asked Questions

Why is my mug cake chewy or rubbery?

Overcooking is the main cause of a rubbery mug cake. Checking on the mug cake often until the top looks set can prevent the cake from being cooked too long.

Can I make mug cakes without eggs?

This chocolate mug cake is naturally egg free! Skipping the eggs creates a softer and fluffier mug cake, rather than making it dense or spongy.

Can I substitute the oil?

Melted butter or coconut oil works best for flavor, but any neutral oil works. You can even use unsweetened applesauce as a substitute.

How do I stop the mug cake from overflowing?

Make sure you use a large enough coffee mug (at least 12 oz) to give the batter room to rise. Keep a close eye on the mug cake in the microwave, and if it starts overflowing, pause the microwave for a little then resume cooking once it goes back down.

  • ⅛ teaspoon salt
  • 8 teaspoon granulated sugar
  • ¼ teaspoon baking powder
  • 2 teaspoon coconut oil, melted
  • 3 tablespoon milk of choice
  • ½ teaspoon pure vanilla extract

Instructions

  • In a large microwave safe mug, combine the cocoa powder, flour, salt, sugar and baking powder until fully combined.
  • Add in the coconut oil, milk and vanilla until fully incorporated. Microwave for 30 seconds and see if it’s done. If not, microwave for 10 second intervals until the top is set.

Notes

Mug size matters. Make sure you use a microwave safe mug that is at least 12 oz (350 ml) to prevent the mug cake from overflowing while cooking.
Do not overcook. Start checking the cake at 30 seconds. Stop cooking as soon as the top looks set. If you overcook the cake, it will turn out rubbery or dry.
Milk substitutions: You can replace the milk with any dairy or non-dairy milk you like. For a vegan mug cake, replace the milk with your favorite plant-based option.
Serve it warm, right out of the microwave! If you want it extra decadent, top with chocolate chips, a scoop of vanilla ice cream or some whipped cream.
To prevent the mug cake from overflowing, make sure to watch it in the microwave. If the cake starts to overflow, pause the microwave then resume once the cake has gone down in size.

  1. Cathleen,
    our mug cake looks so good, but dangerous to have around. good thing it's just a couple of bites, perfect for any chocolate fix.

  2. I have never made mug cake - but I need to! Such a quick, easy way to get a quick fix and delicious dessert!

  3. Deeelicious, and no eggs! This is stuff I always have in my cupboard, mmmmm. Quick chocolate fix for the win 😀
    Do you happen to know how long you would have to bake a microwave cup-cake by the way? I might not have a microwave, but if I am a liiiiitle patient, I can still get my fix I reckon 🙂 x

    1. It would take 8-10 minutes baked at 350. So a little longer than in a microwave, but you still get your personalized chocolate fix 🙂

  4. I still haven't tried making a mug cake but after seeing all the ones you've shared I think I definitely need to get on board 🙂 This looks awesome!

  5. Have never made a mug cake before but this chocolate one does not only look totally delicious but is also super quick and easy to make. Wow!! I'm impressed and I'm going to make one and hide the evidence! Thanks and best wishes!! 😀
