This is for those times you urgently need a brownie, but don't want to make — or, rather, can't justify making — a whole batch. This recipe makes two (four if needs be) fudgy brownies to be snaffled straight from the tin. And they can be turned into glorious sundaes: squodge into glasses with ice cream, pour a little maple syrup over and sprinkle with chopped walnuts. It is worth keeping takeaway-style foil tins in the house just to make these. Take my word for it, it will be a frequent occurrence. For US cup measures, use the toggle at the top of the ingredients list.
