Beat the butter and sugars together until light and fluffy, about 2 minutes.
Next, add the zest of 1 orange, vanilla extract and egg, and beat again to combine.
Fold in the dry ingredients until everything is combined. Place the dough between two pieces of parchment paper.
Roll the dough to the thickness of a pound coin and let it rest in the fridge for 30 minutes.
Once cool, using star cutters or any shape of your choice, cut one large star and then cut a smaller star in the middle and place them on a baking sheet. Repeat with the rest of the dough.
Crush your hard sweets and sprinkle them in the star hole of each biscuit. Place in the fridge for another 15 minutes.
Bake at 375°F for 8 minutes, or until just golden.
As soon as they come out of the oven, use a toothpick or skewer to create a small hole at the top of the biscuit for the string.
Allow the biscuits to cool completely, then place some festive string through each biscuit and hang on the tree.
