To prepare a worlds easiest bread machine pizza dough recipe, first preheat the oven to 450 degrees F. Place the flour, salt, and baking powder in the mixing bowl. Add the milk and mix until combined. Pour the mixture into the dough bowl and cover with plastic wrap. Cover the bowl with cling wrap and let rise until doubled in size, about 1 hour. Bake the pizza in an oven preheated to 400 degrees Fahrenheit (204 degrees Celsius) for 20 to 25 minutes. Remove from oven and allow to cool before slicing into squares.
