Combine the wet and dry ingredients and work together with your hands till a smooth dough is formed. Gather into a ball, wrap in cling film and place in fridge to rest for 30 minutes.
2. Preheat the oven to 180 C / 160 C Fan / Gas 4. Line a baking tray with parchment.
3. On a lightly floured work surface, roll out the biscuit dough to 2mm thick. Cut out desired shapes, such as stars. Cut the centre out of each shape using a smaller cutter. Transfer the biscuits to the parchment-lined tray. Place 1/2 to 1 teaspoon of the crushed sweets in the hollow centre of each biscuit. If desired, use a straw to cut out a hole at the top of each biscuit to easily thread them for Christmas tree decorations later.
4. Bake in the preheated oven for 12 to 18 minutes, or till the biscuits are a light golden brown and the sweets are melted in the centre.
5. Remove from the oven and let cool completely before removing from tray.
