Many of these cakes also work as puddings, so you can serve them hot as a dessert – perhaps with a little cream – or cold as a cake with a cup of tea.
You may find it preferable to mix with a knife or a fork, rather than a spoon, as it is easier to get into the corners of the mug and make sure you have mixed all the ingredients together. If you use a wide mug or a cappuccino cup, you will find that your cakes cook more evenly. If your mug is too tall, you could find that the bottom of the cake goes rather hard. As with the desserts, you can eat them from the mug or run a knife around the edge of the mug and turn them out on to a plate to serve.
Finally, you may like to try making the world’s fastest chocolate cake (well, perhaps not officially but it must be in the running). Mix 5 tablespoons of self-raising flour, 5 tablespoons of chocolate and nut spread, 3 tablespoons of mayonnaise (trust me!) and 1 egg in a mug, then microwave for 3 minutes. And that’s it!
