Recipe Method

1. Melt together the margarine, peanut butter, syrup and sugar in a heavy-based saucepan. Stir to dissolve the sugar and create a smooth sauce.
2. Stir in both cereals until well coated with sauce, and cook gently for 5 minutes.
3. Press the warm mixture into a lightly greased swiss-roll pan and chill until firm enough to slice into bars.
