Ingredients

• ½ cup unsalted butter
• Nonstick aluminum foil
• 1 ½ cups all-purpose flour
• ¼ teaspoon baking soda
• ¼ teaspoon kosher salt
• 1 cup granulated sugar
• 1 large egg (or ¼ cup egg substitute)
• 1 teaspoon vanilla extract
• 1 ½ cups cocoa-flavored rice cereal
• ¾ cup toffee bits

Steps

1. Set butter out to soften. Line baking sheet with foil. Combine flour, baking soda, and salt in medium bowl.
2. Place butter and sugar in large bowl; beat with electric mixer on HIGH until fluffy and pale yellow. Beat in egg and vanilla until combined, then stir in flour mixture (in batches) until dough forms. Stir (fold) in cereal and toffee bits until combined. Cover dough and chill 30 minutes.
3. Preheat oven to 350°F. Scoop dough (about 1 tablespoon each) onto baking sheet about 1 inch apart; bake 10–12 minutes until edges are crisp and centers are set. Let stand 3 minutes to cool on baking sheet, then transfer to wire rack to cool completely before serving. (Makes about 30 cookies.)
