Ingredients:
1 cup (225g) unsalted butter, softened 
¾ cup (150g) granulated sugar 
1 large egg 
1 tsp vanilla extract 
2 ½ cups (315g) all-purpose flour 
½ tsp baking powder
¼ tsp salt
Food coloring (optional, for festive designs) 
Sprinkles, icing, or sanding sugar for decoration 
Instructions:
Prepare the dough:In a large bowl, beat the softened butter and sugar together until light and fluffy.
Add the egg and vanilla extract, mixing until combined.
Mix dry ingredients:In a separate bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until a dough forms.
Chill the dough:Divide the dough into two portions. Wrap each in plastic wrap and refrigerate for 1-2 hours. 
Shape the cookies:Preheat your oven to 350°F (175°C). 
Roll out one portion of dough on a lightly floured surface to about ¼-inch (6mm) thickness.
Use festive cookie cutters to shape the cookies. Transfer them to a baking sheet lined with parchment paper. 
Decorate (optional):Add sprinkles or sanding sugar to the cookies before baking for a festive touch.
Bake:Bake in the preheated oven for 8-10 minutes, or until the edges are lightly golden. 
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Decorate further:Once cooled, decorate with icing or additional sprinkles if desired.
