Preheat oven to 450 degrees.
In a large bowl, stir the yeast and sugar into the warm water until completely dissolved. Allow mixture to sit and proof for 10 minutes, until foamy.
Add the salt and olive oil to the yeast mixture. Begin adding the flour 1/2 cup at a time, stirring after each addition.
When the dough has pulled away from the sides of the bowl and is no longer sticky, knead the dough for 3 minutes in the bowl or on a well floured surface.
Roll or pat the dough out into a large circle about 1/4 inch thick, and place on oiled pizza pan.
Bake crust for 5 minutes. Remove crust from oven, and top as desired. Bake for an additional 10 minutes.
Optional: In a small bowl, microwave the butter and garlic. Remove pizza from oven and brush with the garlic butter, place pizza under broiler for 1-2 minutes, until crust is golden brown.
