Preheat oven to 220°C | 425°F. Remove pizza dough onto a lightly floured work surface and allow it to come to room temperature (about 1 hour or follow package instructions). Slice dough into 12 equal pieces. Using a rolling pin or your hands, roll out each dough into 13-cm or 5-inch rounds. Lightly spray a 12-capacity muffin pan with oil. Gently press each dough piece into each muffin cup to fit into the base and sides.
Assemble your pizzas: Place 2 slices of mozzarella cheese onto each dough first to prevent the dough from getting soggy. Layer with 1 teaspoon pizza sauce; 2-3 tomato slices; a pinch of shredded basil; one more slice of mozzarella; and top with extra shredded basil. Sprinkle a small amount of shredded mozzarella onto the tops; drizzle with a little balsamic glaze and bake until dough is golden brown and crisp (about 12-15 minutes). Allow to cool slightly before removing from muffin pan.
