Notes
Your brownie batter won't fill your mug all the way to the top. In fact, once you've removed it from the microwave it will only fill up about half of a regular sized mug
Don't forget the salt. Just a tiny pinch of salt can help bring out the strong and rich chocolatey flavour.
Serve straight out of the microwave and eat whilst still warm.
You can make this recipe slightly lighter by adjusting the portion of chocolate used from 20 to 10g.
Substitute regular plain flour for plain gluten-free flour to make this recipe gluten free.
