Why You Need To Try This Brownie

- Satisfies all your chocolate cravings
- Can be customised easily
- You won’t believe how easy it is until you try!
The Ingredients
These are the seven ingredients you’ll need to make the mug brownie.
A few notes about the ingredients.
Plain flour - I find that plain flour (also called all purpose flour) works best. Do not use wholemeal flour or strong bread flour. Can be substituted for plain gluten-free flour.
Light brown sugar - Helps give a slightly chewier texture in comparison with white sugar. However, you can substitute this for pretty much any sugar of your choice (except from powdered sugar of course!)
Plant milk - I like to use unsweetened soy, almond or oat milk. Using sweetened plant milk might make your brownie sweetener than intended.
Step-by-Step Images
Making a vegan mug brownie is super easy, but let’s break it down into a few quick steps. Scroll to the bottom to watch the recipe video in full.
- Grab your favourite microwave-safe mug. Add all your dry ingredients (leave out chocolate for now). Mix well.
- Add oil and milk on top. Mix well until combined.
- Chop up your chocolate.
- Stir ½ of the chocolate through your mixture and sprinkle ½ on top.
- Microwave for 1 minute on 700 watts (or for 50 seconds in an 800-watt microwave, 40 seconds in a 900-watt microwave).
- Best enjoyed straight out of the microwave whilst still warm and gooey.
Expert Tips
Don’t forget the salt
Just a tiny pinch of salt can help bring out the strong and rich chocolatey flavour. Make sure you don’t skip this part.
You won’t actually be able to taste the salt, it’s simply there to make the chocolate flavour more intense.
Read more about why salt makes chocolate taste better here.
Serve when warm
Serve straight out of the microwave and eat whilst still warm.
Mind the size
Your brownie batter won't fill your mug all the way to the top. In fact, it will only fill up about half of a regular sized mug.
Wondering why?
Firstly, smaller portions bake better and more evenly. Secondly, this recipe is meant for 1 person, which means filling it up all the way to the top would make it far too big (unless you are absolutely starving!).
F.A.Q.
When it’s piping hot and the batter has set. This means that the batter isn’t swirling around in the mug, but stays firmly in place.
Yes, feel free to experiment when it comes to this. For best results, I like using 70% dark chocolate. However, I’ve also tried making this recipe using Galaxy’s vegan hazelnut chocolate and this turned out delicious.
It is safe to reheat it by placing it in the microwave for further 10-15 seconds. However, do keep in mind that it’s best enjoyed fresh so reheating it might make it lose some of its quality.
A fudgy brownie will have a higher oil-to-flour ratio. Adding more oil should make your brownie fudgier.
Yes, I've tried this recipe using both 20g and 10g of chocolate. Whilst I prefer the version with more chocolate, you could leave out half of it to make a slightly 'lighter' version of this recipe.
Yes, absolutely. Just substitute regular plain flour for plain gluten-free flour.
