**Prepare the Secret Sauce:** In a small bowl, whisk together mayonnaise, ketchup, sweet pickle relish, yellow mustard, paprika, garlic powder, onion powder, and chopped dill pickles. Mix well until thoroughly combined. Cover and refrigerate for at least 15 minutes to allow the flavors to meld.

**Form the Patties:** Divide the ground beef into four equal portions. Gently form each portion into a patty, about 3/4-inch thick. Don't overwork the meat, as this can make the burgers tough. Create a slight indentation in the center of each patty with your thumb to prevent them from puffing up during cooking.

**Cook the Burgers:** Heat a cast iron skillet or griddle over medium-high heat. Add the patties to the hot skillet, ensuring not to overcrowd. Cook for 3-4 minutes per side for medium-rare, or longer depending on your desired doneness. During the last minute of cooking, top each patty with a slice of cheese, allowing it to melt.

**Toast the Buns:** While the burgers are cooking, lightly butter the cut sides of the brioche buns. Place them cut-side down in a separate pan or on the griddle and toast until golden brown and slightly crispy.

**Assemble the Burgers:** Spread a generous amount of the secret sauce on both the top and bottom toasted buns. Place a cheesy burger patty on the bottom bun. Add any optional toppings like caramelized onions or crispy bacon. Place the top bun on, and your Crack Burger is ready to be devoured!
