Triple Chocolate Peanut Butter Cookies
1. Using electric beaters, beat butter and sugar in a medium mixing bowl until light and creamy. Add egg gradually, beating thoroughly after each addition. Add peanut butter and beat until combined.
2. Using a metal spoon, add sifted flour, soda and cocoa; mix to a soft dough. Roll level tablespoons of mixture into balls. Place on prepared tray and flatten with a fork in a criss-cross pattern. Bake for 20 minutes. Cool on trays for 5 minutes before transfering to wire racks. Allow biscuits to cool completely before decorating.
3. Place white chocolate melts in a small heatproof bowl. Stand over simmering water and stir untel chocolate is melted and smooth. Dip one-third of each cookie in white chocolate. Place on wire rack to set. Melt the dark chocolate melts in the same way, and dip the opposite one-third of each cookie, leaving a plain band in the centre.
Storage time: Cookies may be stored for up to 3 days in an airtight container.
