Preheat Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Cream Butter & Sugar: In a large bowl, cream together the softened butter and sugar until light and fluffy.
Add Egg & Flavour: Beat in the egg, and flavours.
Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
Combine & Roll: Gradually add the dry ingredients to the wet mixture until a dough forms. Roll out the dough on a lightly floured surface to about ¼-inch thickness.
Cut & Bake: Use Halloween-themed cookie cutters to cut shapes, then place on the prepared baking sheet. Bake for 8–10 minutes or until the edges are lightly golden. Cool completely before decorating.
