Activate the Yeast: In a bowl, combine yeast, sugar, and lukewarm milk. Stir and let sit for 5–10 minutes until foamy.
Make the Dough: Add flour, salt, and butter to the yeast mixture. Knead until smooth and elastic. Cover and let it rise for 1 hour, or until doubled in size.
Prepare the Topping: In a small bowl, mix the melted butter, minced garlic, and dried oregano.
Shape and Rest: Roll out the dough into a round shape and place it in a greased skillet. Brush with the garlic butter mixture and let it rest for 10 minutes.
Add Cheese & Bake: Sprinkle mozzarella and Parmesan cheese over the top. Bake in a preheated oven at 375°F (190°C) for 18–20 minutes, or until golden brown and bubbly.
Garnish & Serve: Sprinkle with fresh parsley if desired, slice, and enjoy warm!
