1-First: preheat your grill to medium-high heat, around 400 to 450 degrees F, and let it warm up for 10-15 minutes with the lid closed. This ensures even cooking and helps lock in those juicy flavors. Next, divide the 1 pound of ground beef into 8 equal portions, shaping four into small bases and the other four into flat patties.

2-Now: fill each meat base with ¼ cup mac and cheese, then add ⅛ cup shredded cheddar cheese on top, and season lightly with salt and pepper. Seal things by placing a flat patty over each filled base, pressing the edges tightly to keep everything inside during grilling. Season the outside generously with a mix of 1 tablespoon or 1 teaspoon each of salt, pepper, and garlic powder.

3-Grilling and Assembly Steps

Grill the burgers for about 10 minutes per side until they reach an internal temperature of 175 degrees F for safety and tenderness.

In the last minute, spread the 2 tablespoons of butter on your hamburger buns and toast them on the grill, watching closely to prevent burning.

Finally, assemble the burgers with your favorite toppings and serve right away for the best taste.
