Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.

In a large bowl, cream together the softened butter and sugar until light and fluffy.

Beat in the egg and vanilla extract until well combined.

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the butter mixture, mixing until a soft dough forms.

Fill a cookie press fitted with your favorite Christmas-shaped disc with the dough. Press cookies onto the prepared baking sheets about 1 inch apart.

Decorate each cookie with colored sugar or sprinkles as desired.

Bake for 8-10 minutes, or until the edges are lightly golden. Remove from oven and allow to cool on the baking sheets for a few minutes before transferring to a wire rack to cool completely.
