A pizza cupcake is a miniature pizza baked in a muffin tin. They can be made in less than 30 minutes. While the world’s largest pizza once measured 131 feet in diameter and weighed 51,257 pounds, the cupcakes are more manageable. They come with ooey, gooey mozzarella cheese and mini slices of pepperoni and mild Italian sausage. You can also use your favorite vegetables for a vegetarian version.
