This Homemade In-N-Out Style Cheeseburger is a West Coast legend recreated in your kitchen. Inspired by the iconic California fast-food chain, this burger combines juicy beef patties, melty American cheese, tangy 'spread' sauce, and crisp fresh toppings, all sandwiched inside a soft toasted bun. It's the perfect blend of simplicity, flavor, and nostalgic indulgence.

Instructions
Make the Secret Spread: In a small bowl, whisk together mayonnaise, ketchup, sweet pickle relish, and white vinegar. Mix until well combined and refrigerate until needed.
Form the Patties: Divide the ground beef into four equal balls (about 4 oz each), then press each into thin patties about 1/4-inch thick. Season both sides with salt and pepper.
Toast the Buns: In a skillet over medium heat (approximately 350°F / 175°C), toast the cut sides of the buns until golden brown. Set aside.
Cook the Patties: Heat a cast-iron skillet or griddle over medium-high heat (around 400°F / 200°C). Add the patties and cook for 2–3 minutes per side. In the last minute, top two patties with a slice of American cheese and stack an un-cheesed patty underneath to form double burgers.
Assemble: Spread sauce on each side of the toasted buns. Layer lettuce, tomato, onion, and the hot stacked patties. Cap with the top bun.

Notes
Use a burger press or flat spatula with wax paper to form evenly thin patties.
For a more authentic flavor, lightly steam the burger after assembling by covering it briefly with a metal bowl on the griddle.
For dietary adaptations, use turkey or plant-based patties and vegan cheese/mayonnaise.
