I experimented a lot with chocolate mug brownies before getting the consistency right. Here is the perfected mug brownie recipe.
Vegan Mug Brownie Ingredients

3 tbsp sugar
1 tbsp sunflower oil (or any oil that isn't strong tasting)

3 tbsp water
tiny pinch of salt
Vegan Mug Brownie Recipe
1. Combine flour, sugar, cocoa and oil in a large mug.
2. Add the water SLOWLY to the mug, while mixing with a spoon, so there are no lumps.
3. Microwave for 1.5 minutes.
4. Moan with pleasure.
A great variation is to add raspberry jam to the mix before microwaving.
You can change the consistency of your mug brownie by adjusting the amount of oil - more oil with give you a gooey mug brownie, whereas less oil will produce something more like cake.
