Method

​1 Preheat the oven to 180°C/fan 160°C/gas mark 4 and line two baking trays with baking parchment paper.

2 In a large mixing bowl, beat the butter and sugar together until soft and creamy. Add the vanilla extract and beat again. Add the almonds and flour and work into the butter mixture with a wooden spoon until it forms a dough.

3 Roll the dough into a sausage about 40cm. Divide the dough into quarters. Slice each quarter into 10 – 12 pieces depending on what size biscuits you want.

4 Using your hands roll each piece of dough into a small ball and place on the baking tray. Flatten each ball slightly with your fingers leaving a 3cm gap between each one.

5 Bake for 15 minutes until golden. Leave to cool on a wire rack. When the biscuits are completely cool, sandwich the two biscuits together with some chocolate spread.
