seedless jam - raspberry or strawberry work very well
Instructions
Preheat the oven to 170c/325f / Gas 3. Take 2 baking trays and line with baking paper.
Place the margarine in a bowl and sift in the icing sugar. Add the vanilla essence and beat mixture until light and fluffy. Sift in the flour, mixing gently until well combined.
Spoon the mixture into a large piping bag fitted with a large star nozzle. Pipe rings on a baking sheet. Space out, leaving room for the biscuits to expand during cooking. Place a small dollop of jam in the centre of each biscuit.
Bake for 20-25 mins, or until biscuits are pale and golden brown. Remove from the oven and leave to cool.
