In a large mixing bowl, combine 1-3/4 cups of all-purpose flour, 1 envelope of Fleischmann's RapidRise Yeast, 1/4 cup of sugar, and 3/4 teaspoon of salt. Mix these dry ingredients together until well combined.
In a separate bowl, mix together 2/3 cup of very warm water (120 to 130°F), 3/4 teaspoon of vanilla extract, and 3 tablespoons of melted butter or margarine. Pour this mixture into the dry ingredients and stir until a dough begins to form.
Turn the dough onto a lightly floured surface and knead for about 5-7 minutes, until the dough is smooth and elastic. If the dough is too sticky, gradually add more flour until you reach the right consistency.
Place the kneaded dough in a greased bowl, cover it with a clean kitchen towel, and let it rise in a warm place for about 30 minutes, or until it has doubled in size.
While the dough is rising, preheat your oven to 375°F (190°C).
Once the dough has risen, punch it down and divide it into two equal portions. Roll each portion out into a round pizza shape, about 1/4 inch thick. Place the shaped dough onto a parchment-lined baking sheet.
Sprinkle 1/2 cup of miniature chocolate chips evenly over the surface of each pizza, pressing them gently into the dough.
Bake the dessert pizzas in the preheated oven for about 15-20 minutes, or until they are lightly golden and the chocolate chips are melted.
Once out of the oven, let the pizzas cool slightly. Then, drizzle your choice of sauces—like peanut butter, hot fudge, or caramel sauce—over the top. Finish with your favorite toppings, from fresh fruits to colorful sprinkles.
