Spicy Popper Smash Burgers

Finely chop the sliced jalapeño peppers. In a bowl, vigorously mix the cream cheese, goat cheese, and chopped jalapeños with a fork until smooth and fully integrated.

Divide the ground beef into two round balls. Heat a cast-iron skillet over high heat until smoking and melt the butter. Place the beef balls in the pan, then use a heavy spatula or press to smash them completely flat. Season heavily with salt. Cook undisturbed for 2 minutes until a deep, lacy brown crust forms.

Flip the patties, immediately top each with a slice of American cheese, and cook for 1 more minute until melted. Slather the toasted keto buns with a thick layer of the jalapeño popper spread, insert the cheesy patties, press the buns together, and serve warm.
