Ingredients
Method
1.Preheat oven to 180°C (160°C fan-forced). Line 2 baking trays with baking paper. Make cookies with oil and egg following packet directions, adding zest to cookie mixture. Roll tablespoons of mixture into 16 balls. Place on prepared trays; flatten slightly.
2.Bake for 12 minutes (don’t overcook or biscuits will be too crisp). Stand on trays for 5 minutes, then transfer to a wire rack to cool.
3.Combine jelly crystals and 1 cup boiling water in a medium heatproof bowl; stir until jelly is completely dissolved. Stir in 3/4 cup cold water. Pour into a 30x20cm (base measurement) slice pan. Chill for 2 hours or until set.
4.Using a 6.5cm pastry cutter, cut 8 rounds from jelly. Place a scoop of ice-cream on the flat side of 8 cookies. Smooth slightly to form a flat surface. Top each with a jelly round. Sandwich with remaining cookies. Serve immediately.
