Grate the cheese on the fine side of a cheese grater.
Combine cheese, butter, flour, cayenne pepper, Worcestershire sauce, and salt in a large bowl. Mix together with a wooden spoon. You may have to use your hands to get it mixed together well.Note: You can use an electric mixer for this step, but mix the Rice Krispies in by hand.
Once all the flour has been incorporated, add the cereal and gently mix it in.
Shape mixture into 1-inch balls. Place them spread out on 2 ungreased baking sheets. Flatten each ball some with a fork.
Bake for 15 minutes. Cool on pan.
