First, allow the pizza dough to sit out and come to room temperature. This makes it much more pliable and easier to work with. Once it’s ready, use a bench scraper or a sharp knife to divide the dough into 12 equal portions.
Pour about one teaspoon of olive oil into each cup of a standard muffin pan. Gently form each piece of dough into a rough ball and place it in an oiled cup. Cover the pan with a clean towel and let it rest while your oven preheats to 400°F; the warmth will help the dough rise slightly.
While the dough rests, prepare your aromatic oil. Finely chop the garlic and the fresh rosemary leaves. Heat the remaining olive oil in a small saucepan over medium heat, then carefully add the garlic and rosemary. Stir until the oil stops sizzling and becomes fragrant.
Spoon the infused garlic and rosemary oil generously over each ball of dough. Using two fingers, gently press into the dough to create dimples and help the toppings adhere. Sprinkle with flaky salt and bake for 14-16 minutes, until golden brown and crispy.
