Preheat your grill or stovetop skillet over medium-high heat. Form the ground beef into four evenly sized patties, pressing a slight indentation in the center of each to prevent puffing up during cooking.
Place the patties on the grill or skillet, listening for a satisfying sizzle. Cook for about 4-5 minutes per side, until nicely browned and cooked through, then transfer to a baking sheet.
Lay a slice of cheddar cheese on top of each hot burger patty. Allow the cheese to melt gently over the meat for about 1-2 minutes, creating a gooey, flavorful coating.
While the cheese melts, toast the buns lightly on the grill or in a toaster until golden and crispy. Set aside for assembly.
Spread a small amount of mayonnaise on each bun's bottom half for adhesion. Place each cheesy patty on the buns.
Decorate the monster hair by shaping cotton candy into tufts and placing them atop each burger, giving the appearance of messy, colorful hair.
Attach two googly eyes to each burger using a dab of mayonnaise or ketchup to secure them, giving the monsters expressive faces.
Create monster mouths by slicing small pickles in half, then attaching them near the bottom of each burger to resemble mouths. Use ketchup or mayonnaise to add some extra details if desired.
Place the top buns on each burger to complete your monstrous creations. Present them with the playful, messy decorations intact, ready to serve and delight.
Enjoy these colorful, fun monsters with friends and family for a festive Halloween meal that’s as amusing as it is tasty.
