Mix the sugars and corn syrup in a sauce pan. Bring to boil for one minute. Remove from heat. Add peanut butter, stir until smooth. In a separate bowl mix cornflakes and peanuts, then pour sugar/peanut butter mixture over and stir. Press into buttered 9 x 13 pan.

Melt chocolate and butterscotch chips about 1 to 1-1/2 minutes in the microwave or over a double boiler. Stir and melt longer if necessary. Stir until smooth then use as frosting over mixture in pan.

You can use milk chocolate chips alone for the frosting.
