Preheat oven to 350°F Dissolve yeast in the warm water. Let sit for 5 minutes. Add sugar, milk and salt. Add enough flour to make a soupy like mixture. Add the rest of the flour, enough to form a moderately stiff dough. Knead the dough until smooth. (Or you can use a Kitchen Aid mixer with the dough hook). Roll the dough into the size and shape of your baking pan. Spread half of the butter onto the bottom of the pan and then place the dough into the pan. Let rise in warm, draft-free place for 15 minutes. Spread remaining butter on the top of the dough. Top dough with mozzarella cheese, garlic powder, parmesan, salt and pepper to taste. Bake at 350°F for 20 to 25 or until golden brown. Cut into breadsticks and serve with marinara sauce.
