Rub the flour and butter together until it looks crumbly. Then you need to add the yeast and mix together. Add in the water gradually so it doesn't get too wet then mix together until it looks stiff and doughy.
Finally begin to roll the dough out to whatever shape and size you want (but not too thin or it won't work). Transfer to a lightly floured pizza tray. Add toppings of your choice.
Bake in the preheated oven until the dough is golden brown and firm throughout, about 20 minutes. If you have added cheese, the cheese should be melted and golden brown. Remove from the oven, slice and serve.
