Toffee ice-cream sandwiches

Method

• step 1

  Put a biscuit in the bottom of the cutter and top with ice cream, pushing it to the edges. Top with a second biscuit and gently push the sandwich out of the cutter. Repeat with the rest of the biscuits and ice cream. Put the sandwiches in a box in the freezer for at least 3 hours, until really firm.

• step 2

  Melt the chocolate in a bowl set over, not in, a pan of simmering water.

• step 3

  Line a baking tray (one that will fit in the freezer) with non-stick paper. Dip half of each ice-cream sandwich (horizontally or vertically) into the chocolate and lay them on the baking tray. Freeze until firm, then transfer to a plastic box with a lid. Freeze until needed. Serve with a wrap of greaseproof paper to hold them in.
