A double cheeseburger is a popular fast-food item that consists of two beef patties stacked on top of each other, each topped with a slice of cheese. The patties are usually grilled or fried and are often seasoned with salt and pepper. Common toppings include lettuce, tomato, pickles, onions, and condiments like ketchup and mustard, all served in a soft hamburger bun. This burger variant is a favorite among many due to its rich flavor and satisfying texture. It is commonly found in fast-food chains like McDonald's and Burger King, as well as in diners and restaurants across the world.
