Prepare the Dough:

1. Activate the Yeast: In a small bowl, mix the warm water, sugar, and active dry yeast. Let it sit for 5-10 minutes until it becomes frothy.
2. Mix the Dough: In a large bowl, combine the flour and salt. Make a well in the center and add the yeast mixture and olive oil.
3. Knead the Dough: Stir until the dough begins to come together, then knead on a lightly floured surface for about 5 minutes, until smooth and elastic.
4. Let It Rise: Place the dough in a lightly oiled bowl, cover it with a clean cloth, and let it rise for 1 hour, or until it doubles in size.

Shape the Pizzas:

1. Preheat the Oven: Preheat your oven to 475°F (245°C).
2. Divide the Dough: Punch down the dough and divide it into 4 equal portions.
3. Shape the Dough: Roll out each portion into a small oval or heart shape, about 6 inches wide, on a floured surface.
4. Transfer to Baking Sheet: Transfer the heart-shaped dough onto a parchment-lined baking sheet.

Add the Toppings:

1. Sauce and Cheese: Spread a thin layer of pizza sauce over each pizza base. Sprinkle with shredded mozzarella cheese, then add your desired toppings (such as sliced pepperoni).
2. Brush the Crust: Brush the edges of the dough with a little olive oil for a golden, crispy crust.

Bake the Pizzas:

1. Bake: Bake in the preheated oven for 10-12 minutes, or until the crust is golden and the cheese is bubbly and slightly browned.

Serve:

1. Cool and Serve: Remove the mini pizzas from the oven and let them cool for a minute before serving.
2. Garnish: Optionally, top with fresh basil leaves for an extra burst of flavor.
