1. In the large bowl of a stand mixer, combine yeast, sugar, melted butter, and warm (not hot) milk. Let rest 10 minutes to allow yeast to activate. Foam will form along the surface.
2. Combine flour and salt. Using the dough hook attachment, on low speed, slowly begin to add flour mixture until dough forms a ball around the hook, and no longer sticks to the edges of the bowl.
3. Place the ball of dough in a greased bowl and turn over once to coat all of the dough. Cover and allow dough to rise in a warm, draft-free location. The dough will double in volume. This should take about 45 minutes.
4. Grease a large pizza pan; spread dough over pan. Spread desired sauce and evenly sprinkle Mozzarella cheese over the sauce. Evenly distribute other desired toppings over the entire pizza. Bake the pizza at 425° F for 15 minutes or until cheese begins to turn golden. Remove pizza from the oven. Serve immediately.
