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

In a large bowl, cream together 1 cup of room-temperature unsalted butter with 2 cups of shredded sharp cheddar cheese for 2-3 minutes until smooth.

Mix in 2 teaspoons of Worcestershire sauce, 1 teaspoon cayenne pepper, 1 teaspoon salt, and ¼ teaspoon garlic powder until well combined.

Gradually add in 2 cups of sifted all-purpose flour until just incorporated.

Gently fold in 2 cups of Rice Krispie cereal, ensuring not to crush them.

Roll balls of dough about the size of a tablespoon, flatten slightly, and place on the prepared baking sheet.

Optionally sprinkle additional cayenne pepper on top for more heat.

Bake for 13-15 minutes until golden brown around the edges and crisp on top.

Allow to cool on the baking sheet for 5 minutes before transferring to a wire rack.

Store in an airtight container at room temperature for up to 7 days.
