The mugfin

Other foodstuffs I've learnt of from the Internet. The cake in a mug. I've been messing around with a few recipes recently and think this works quite well:
Mix up:
2oz melted butter
2 tbspn full fat greek yoghurt
1 large egg
2 level tbspn sugar
1/2 tbspn maple syrup
2 level tbspn cocoa
2 tbspn self raising flour
1 tbspn oat bran
Pour into 2 mugs and nuke for 4 minutes. It rises much higher than any other recipe I've tried - must be the acid in the yogurt reacting with something. You could probably add more cocoa if you like it very chocolatey. This also contains less sugar than other recipes I've seen. You could also replace the bran with another spoon of flour. A lot of online recipes use oil rather than butter, which is, I believe, the American way with cakes but butter makes it taste better.
