1/2 cup unsalted butter
1 cup packed brown sugar
1/3 cup peanut butter
1 large egg
1 teaspoon vanilla extract
1 teaspoon baking soda
1/2 teaspoon salt
1 cup finely ground corn flakes
3/4 cup all purpose flour
3/4 cup toffee bits
1 cup semi-sweet chocolate chips
Melt butter in a small saucepan over medium heat; cook 2 minutes, whisking frequently, until butter foams and starts to turn golden. Pour butter into a large mixing bowl.
Add brown sugar to mixing bowl. Mix, using a mixer on medium speed, for 2 minutes. Mix in peanut butter, egg, vanilla, baking soda and salt until well combined - about 1 minute. Reduce mixer speed to low and beat in corn flake, flour, toffee bits and chocolate chocolate chips until just combined. Chill dough in refrigerator for 20 minutes.
Heat oven to 350 degrees F. Coat cookie sheets with cooking spray.
Drop rounded tablespoons of dough onto cookie sheets. Bake 10-12 minutes or until light golden brown. Cool 1 minute before transferring cookies to wire racks to cool.
Makes about 10-12 big cookies
