Muffin In A Mug - Gift Mug With Recipe & Instructions 5 "Boil the kettle. Make a muffin" Mr Lewis 18 July 2016 Thought this was just a gimmick. How wrong I was. A little tweek here and there now an almost muffin is made in the time it takes to make a cup of tea. Enough for two as a pudding with custard. It would be handy to know the weight of flour and sugar needed, I also have the cake in a mug, same results. Yummy Yummy A note from the team Thanks for the feedback, I'm glad it's been a success. For easiness there is no weighing required just follow the measurement guidelines inside the mug and enjoy.
