Brownie in a mug..

Oh my god this was the best thing I ever made! The ingredients are on google but we added chocolate chips and used hot chocolate powder instead of cocoa baking powder and it was heaven! We added Ben and jerrys phish food and cookie dough to the top (which is on offer for £3 a tub at sainsburys) and then added more chocolate chips! It's so quick and tasty and I thought it deserved a post
