In a mixing bowl, cream together the butter and shredded cheddar cheese until smooth.
Gradually add in the flour, Worcestershire sauce, cayenne pepper, salt, and garlic powder. Mix until it resembles dough.
Fold in the Rice Krispie cereal.
Pinch off pieces of dough, roll into balls, and flatten them on a parchment-lined baking sheet. Sprinkle with cayenne pepper.
