Using an electric mixer on medium speed, beat together the cheese and butter until fluffy, about 3 minutes.

Reduce the mixer speed to low and mix in the salt, cayenne, black pepper, and garlic powder.

Using a rubber spatula, stir in the flour ½ cup at a time, until the ingredients are well combined and a dough forms.

Turn the dough out onto a piece of parchment paper or plastic wrap and shape it into a 1-inch-diameter log. Twist the ends of the parchment or plastic wrap to seal. Refrigerate for 30 minutes.

Preheat oven to 375 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.

Remove the dough from the refrigerator, unwrap, and place on a cutting board. Cut the log into ⅛-inch-thick slices and place ¼ inch apart on the prepared baking sheet.

Bake until light golden brown, about 15 minutes. Transfer the pan to a wire rack and allow the crackers to cool completely.
