Vegan Chocolate Brownie Mug Cake – Two Ways

Chocolate brownie mug cake

This recipe that Im about to share with you may just change your life. Because since I created it, it has quite possibly changed mine.

Sometimes, there are those evenings where you just want dessert NOW. You don’t want to start turning on the oven; you don’t want to start measuring out ingredients. You just want it straight away, or at the very least, in 5-10 minutes.

Or there may be those days when you just crave chocolate cake, like, all day. It may be down to stress; it may the body naturally craving what it needs, or it may be just be good ol’ hormones.

Whatever the reason is, those days actually exist, and few things are more disappointing than realising you don’t actually have any chocolate cake in the house.

Like most other people in this world, I work a normal, 9-5:30pm job, so am more than aware of how having a nice dinner or dessert to look forward to when you come home can make a big difference to your day. Like it or not, food is not only for fuel – it has the ability to impact our mood, which in turn affects everything else.

So it’s all the more important that we don’t deprive ourselves of the fun stuff.

“But I can’t eat chocolate cake every day! That’s not healthy!” you might be thinking.

Well, luckily, my friends, this is a vegan chocolate mug cake with a difference. It is healthy!

Oil Free, Naturally Sweetened, Low-Fat

Microwavable mug cakes are of course nothing new in the foodie blog world. Whatever genius originally came up with the concept of using the microwave to make an instantaneous cake, let’s give them credit right now. In fact, I dedicate this recipe to you, whoever you are, because without you this recipe would not exist.

However, I’ve experimented a lot with microwave mug cakes over the last couple of years, and I always had my qualms.

First of all, many of them are made with traditional white or wholemeal flour, which is fine, but actually other flours will work too.

Secondly, these mug cakes nearly always contained oil of some kind, such as coconut or vegetable oil. Again, there is nothing wrong with oil in small amounts, but if you want the freedom to eat this cake however many times a week you wish, it is better to leave it out.

This healthy chocolate mug cake was created to fit my own personal diet, which is no oil, low fat, and using a wholegrain as the base. Usually any type of sugar will work in these cakes; I choose to use date sugar (for an awesome sugar-free version) or coconut sugar. However, brown cane sugar or sucanat will work too.

Instead of oil, I use fruit puree. Used as an oil replacement in lots of other low-fat cakes and bakes, apple puree, date puree or mashed banana is the perfect way to add moistness without the calories.

As a bonus, they both add fibre, minerals and a bit of extra sweetener too! In fact, I’ve even sometimes left out the sugar in this cake, sweetening it simply with mashed banana instead.

Grain-free Version

Because I want dessert to be available to everybody, regardless of what diet they follow, I created two versions of this pudding.

The first uses oats as the base, making this cake a great source of slow-releasing energy as well as fibre and vitamins.

The second uses almond flour to create a grain-free, lower-carb version. If you’re following a paleo or low-carb lifestyle, this option may be preferable to you (though you may want to leave out the sugar if you’re concerned about that).

For me, I prefer the lower-fat version, so I always use oats. Enjoy this cake topped with coconut yoghurt, your favourite custard, cream or ice cream…or just enjoy as it is! For these photos I drizzled mine with some of the amazing Oatly pouring cream.

Vegan Chocolate Mug Cake Recipe – Low Fat


  • 3 tbsp oat flour (oats ground up in your blender)
  • 1 tbsp cocoa powder
  • 3 tsp coconut sugar*/date sugar* (can also use brown cane sugar)
  • 3 tsp apple puree/date puree, OR 1/2 mashed banana
  • 1/4 tsp baking soda
  • 3 tbsp non-dairy milk
  • 1 tbsp dark/vegan chocolate chips


  1. Once you’ve ground your oats into a fine flour, place into a mug and mix with the cocoa powder, sugar and baking soda.
  2. Add whatever fruit puree you’re using, the non-dairy milk and the chocolate chips. Whisk together thoroughly until there are no lumps.
  3. Microwave for 1:20 mins, or more if it’s too gooey for your liking.
  4. Enjoy as it is, or top with your favourite non-dairy custard, cream or ice-cream.


Vegan Chocolate Mug Cake – Grain-free



Follow steps 1-3 above.

This version may need a little longer in the microwave than the oat version, as almonds are much more moist. However, that won’t be a problem if you like a gooier cake!

  1. I tried this recipe today, realised mid blending the oats that I had no cocoa powder at home!! I tried the recipe without it, sprinkled in some cinnamon and topped it with almond butter. It was sooo good, even without the extra chocolatey goodness! I put it in the microwave for about 1:40 mins, it was perfectly soft and moist, not overly dense, packed with flavour unlike other v/gf mug cakes I’ve made in the past!! And takes no time at all!! Definitely my all time favourite when I’m looking for a quick fix to indulge into :))

    1. Oh my gawd, that sounds amazing!! So glad you were still able to make it work without the cocoa. Thank you for trying it. I might try it your way!

  2. i made this in the silicon muffin pan and it was yummy.. i also cooked in my oven and topped with date syrup toasted pecans and coconut for a german choc treat, (my husband favorite choc cake).. i doubled recipe and it made 4 cakes (muffin size)

  3. Oh dear, this is a dangerous recipe!! Just made a double batch in 2 mugs for OH and myself. Gorgeously rich and far too easy for such a delicious dessert! I didn’t have extra chocolate chips but, with dark Spanish cocoa powder, any more chocolate would have been too much!

    1. Haha, great to hear!! I am so glad you are enjoying the recipe, I’m sorry it’s so dangerous 😉

      The chocolate chips are a great addition, but I can imagine with Spanish cocoa powder it was equally as delish :p
