First get a good size cup :)

Then add a table spoon of self raising flour...

A table spoon of caster sugar...

A dessert spoon of room temperature butter...

And one egg!:)

Get a fork and mix really well until it looks like this.

Now you can add anything you want, like vanilla flavouring, chocolate chunks, lemon zest...get creative!:)

I added hot chocolate powder and dried cranberries to mine:)

Put your cake in the microwave for 3 minuets...
