In a small bowl, combine 1 1/3 cup warm water and 2 teaspoons sugar. Stir until sugar dissolves, then add 1 1/2 teaspoons yeast. Let sit for 5 minutes until frothy.
In a large mixing bowl, combine 2 cups unbleached all-purpose flour, 1 cup bread flour, 1 teaspoon baking powder, 1/4 teaspoon garlic powder, 1/4 teaspoon onion powder, 3/8 teaspoon MSG, and 1 1/4 teaspoons salt.
Pour 2 tablespoons olive oil and the activated yeast mixture into the dry ingredients. Stir until the dough begins to form.
Transfer the dough to a floured surface (sprinkled with cornmeal) and knead for 5-7 minutes until smooth and elastic. Add flour if dough is too sticky.
Place dough in a lightly greased bowl, cover with a cloth, and let rise for 1 hour or until doubled in size.
Punch down the dough, then roll it out on a floured surface into your desired pizza shape. Preheat oven to 475°F (245°C). Top your dough with sauce, cheese, and toppings, then bake for 10-12 minutes until golden brown.2 tablespoons cornmeal
