Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine room temperature unsalted butter and freshly shredded sharp cheddar cheese and cream together until smooth.

Mix in the Worcestershire sauce, cayenne pepper, salt, and garlic powder until well incorporated.

Gradually sift in the all-purpose flour and stir until a soft dough forms.

Gently fold in the Rice Krispie cereal without crushing them.

Pinch off small pieces of dough (about 1 teaspoon each) and roll them into balls, placing them on the prepared baking sheet.

Using a fork, gently flatten each ball to about 1/2 inch thick and sprinkle with extra cayenne if desired.

Bake for 13-15 minutes or until the edges are golden brown.

Remove from oven and cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.
