Add the ingredients into a bowl and mix with a whisk. Add the water and mix about 100 times with a spoon.
Place it on parchment paper using the spoon, and stretch it out into a circle with a diameter of 12 cm.
Spread ketchup on top, and top with sliced wiener sausage, corn, and pizza cheese.
Bake for about 8 minutes, and you're done.
Please follow the recipe as much as you can. If you change the amount of the ingredients, the size of the pizza, and the temperature, etc., the texture of the final result might change as well.
