As you'd expect the recipe is crazy simple- quite similar to my other cake in a mug recipe. The texture is pretty similar, though more fluffy rather than dense.
4 tablespoons self raising flour
2 tablespoons sugar
2 tablespoons cocoa powder
3 tablespoons milk
3 tablespoons oil (I used sunflower)
1) Place the dry ingredients (flour, sugar and cocoa powder) into your mug and stir to remove any lumps.
2) Add the wet ingredients (oil and milk- you can easily make the recipe vegan by using soy milk) and stir thoroughly :)
3) Scrape any excess mixture to the bottom of the mug, and cook in the microwave for about 2 minutes (time will vary depending on your microwave power etc.) This one didn't rise much for me, but somehow managed to get fully cooked and light and fluffy :)
This cake would be extra yummy with extra ingredients like coffee powder (for a deeper flavour) or chocolate chips (extra chocolatelyness!)
It's super-yummy and very fast (fast enough to whip up in the BGT ad break!) I hope you'll enjoy it!
