• Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
• In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
• Add the egg and vanilla extract to the butter-sugar mixture. Mix until well combined.
• In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms.
• Divide the dough in half, shape each half into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.
• On a floured surface, roll out the chilled dough to about 1/4 inch thickness. Use cookie cutters to cut out desired shapes. If you want to add sprinkles, gently press them onto the cookies before placing them on the baking sheet.
• Place the cut cookies on the prepared baking sheets and bake for 8-10 minutes or until the edges are lightly golden.
• Allow the cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.

Icing Sugar Glaze:

• In a bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more sugar for thickness or more milk for thinning.
• If you want coloured icing, divide the icing into bowls and add food colouring of your choice to each bowl.
• Once the cookies are completely cooled, use a spoon or piping bag to drizzle or spread the icing onto the cookies. Top with sprinkles of choice if you prefer.
• Allow the icing to set before storing or serving the cookies. Enjoy! :)
