Hot Cocoa Mug Cake

When it comes to single serving desserts, I love a giant chocolate chip cookie, lava cake, and this hot chocolate mug cake. 

Whenever I don’t have a spare cookie or brownie in my refrigerator, I always end up making a mug cake or mug brownie for dessert. They are quick, easy, and take less than 5 minutes. There is also no leftovers because they are designed for ONE person, and one person only.

Before we had restrictions in place, I used to have a weekly dinner date with one of my close friends. After dinner, we’d always make mug cakes, and every single time we’d try and change up the flavors. Recently, my friend brought over some hot chocolate mix and added some to her chocolate mug cake. Not only did it taste incredible, but it tasted like hot chocolate in cake form!

Now, you don’t need to add any hot cocoa mix at all, and STILL achieve the hot cocoa flavor. This mug cake has a moist and fluffy texture, and with plenty of chocolate throughout.

No eggs or dairy is needed, but you’d never be able to tell! It tastes even better with some marshmallows on top and some dairy free whipped cream. 

I’ve been making it every night this week, and has made me even more excited for the holiday season!

How do you make a hot chocolate mug cake?

The Ingredients

  • All purpose flour– Either plain flour or gluten free flour. If you use the latter, be sure that it has xanthan gum added to it. 
  • Cocoa powder– Use a good quality cocoa powder, to really bring out the chocolate flavor. For a richer flavor, use dark cocoa powder. 
  • Granulated sweetener of choice– Either white or brown sugar can be used. See my tips below to make it healthier and sugar free.
  • Salt– Brings out the sweetness of the other ingredients, and balances the cocoa powder. 
  • Baking soda– Gives the mug cake some rise and fluffiness.
  • Oil OR butter– Either oil or butter can be used. If you use unsalted butter, omit the salt. 
  • Vinegar– White vinegar or apple cider vinegar. This works with the baking soda to replace the need for any eggs.
  • Vanilla extract- A must for any good cake or mug cake. 
  • Water OR milk– I found this mug cake perfectly fine with water, but if you’d like a smoother and richer cake, use your favorite plant based or standard milk. 
  • Mini marshmallows and whipped cream– What is hot chocolate without marshmallows or whipped cream? Add these two at the end, once the mug cake is warm. 

The Instructions

In a small mixing bowl, whisk together all the ingredients, except for the mini marshmallows and cream, until combined. Transfer into a large, greased mug. Microwave for 60 seconds, before removing from the microwave, before topping with mini marshmallows and whipped cream.

Tips to make the best hot chocolate mug brownie

  • If you’d like to make this in the oven, grease a 6-inch ramekin and transfer the batter into it. Bake at 180C/350F in a preheated oven for 10-12 minutes. 
  • Microwave makes and models differ. If your mug cake is still underdone, continue microwaving in 10-second spurts until done.
  • For a richer chocolate flavor, add some chocolate chips in the batter.
  • If you’d like a keto hot chocolate mug cake, make this mug cake and top with coconut whipped cream.

  1. 5 stars
    Such a lovely light and fluffy texture! But it wasn’t nearby chocolatey enough… If I made it again, I would add at least 1 Tbsp – or add chocolate chips, as you mentioned in the post (which I saw later) but not in the actual recipe.

    Thanks!

  2. I just wanted to stop by and tell you that I think you may have created an indestructible recipe. I had a serious sweet tooth craving this evening, all I knew was I needed something sweet and quick. A quick (distracted) scroll through pinterest led me here. I had maybe three of the ingredients but by jove I was determined. I cracked open the pantry and fridge and got creative. No pumpkin? Way overripe avocado. No milk of any kind? Creamer. You get the idea. Somehow your miraculous recipe carried my shoddy ingredient choices through. It turned out fluffy and chocolatey and fulfilled my sweet craving.
    Also I managed to knock over my bottle of vanilla extract so now I can’t walk into my kitchen without my eyes watering.
    Interesting evening.

  3. It was absolutely delicious! Thank you!! I cooked mine a little longer, about 1 min 30 seconds because my “batter” was thinner. I added some rice milk to the blender because it was too thick to blend. But it came out fabulous!

  4. Looks amazing! You mention this has protein podwer in it, but there is none listed in the ingredients. Did I misunderstand or is it missing from the list?
