Gather all your ingredients.

Measure each ingredient using measuring spoons and cups.

In a mixing bowl, combine brown sugar, smoked paprika, kosher salt, black pepper, garlic powder, onion powder, cayenne pepper, mustard powder, and ground cumin.

Whisk or stir until all ingredients are well combined.

Taste the mixture and adjust the spices if desired.

Transfer the spice mix to an air-tight container for storage.

Let the spice rub sit for at least an hour before using for best flavor.

Apply the rub generously to your choice of meat before cooking.
