Use any combination of chips, dried fruit, and nuts you like. The original recipe called for toffee bits and macadamia nuts. My favorite combo is pecans, toffee bits, white chocolate chips and dried cranberries
3 sticks butter, softened
1 cup white sugar
2/3 cup packed brown sugar
2 eggs
1 teaspoon vanilla
2 cups all-purpose flour
2 cups cake flour
2 teaspoons baking soda
1 teaspoon salt
3 cups toffee chips
2 1/2 cups macadamia nuts
Preheat oven to 350º.
Beat the butter and the sugars together until nice and creamy. Add the eggs and vanilla and beat until combined. Add the flours, soda and salt and mix until combined. Fold in any additional ingredients (chips, nuts, etc.)
Scoop tablespoons of dough onto ungreased baking sheets and bake at 350º for about 15 minutes. Allow to cool on the baking sheets for 2 minutes before removing to a wire rack to cool completely.
Makes about 75 cookies depending on the size you scoop them out.
