Preheat your Blackstone griddle to medium-high heat.
Take a large bowl and add the ground beef, salt and black pepper together. Mix everything well.
Form the prepared ground beef into patties. You can use a round jar lid to making the patties. But remember, the lid should be the size of a bun.
Pour some melted butter on Blackstone preheated surface and cook the first side of patties until the bottom is perfectly browned.
Now, flip the pattiy over and place the american cheese on it and cook until the cheese melted.
While the patties cooking, toast the buns on griddle.
Once the patties are ready, simply place the patty onto the bottom half of the toasted bun.
Add your desired toppings such as onions, sliced tomatoes, and lettuce.
Add sauces like ketchup, mayonnaise or mustard.
And finally, your smash burger is ready!
