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

In a mixing bowl, cream together 1 cup of unsalted butter and 1.5 cups of shredded sharp cheddar cheese until smooth.

Mix in 1 tablespoon of Worcestershire sauce, 0.5 teaspoon of cayenne pepper, a pinch of salt, and 0.5 teaspoon of garlic powder until evenly combined.

Gradually sift in 2 cups of all-purpose flour, mixing gently to form a cohesive dough without overworking it.

Fold in 3 cups of Rice Krispie cereal carefully to maintain its crispness.

Scoop tablespoon-sized portions and roll them into balls, placing them on the baking sheet.

Flatten each ball with a fork to form disks about ¼ inch thick and optionally sprinkle with cayenne pepper.

Bake for 13 to 15 minutes until edges are golden brown and crisp.

Allow to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
