Preheat the oven to 350°F (175°C).

Line baking sheets with parchment paper.

In a mixing bowl, beat the softened butter and granulated sugar together using an electric mixer until light and fluffy, about 3 minutes.

Add the egg and vanilla extract to the butter mixture and beat until well combined.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined.

Fill the cookie press with dough according to the manufacturer’s instructions.

Pipe the dough onto the prepared baking sheets, spacing cookies about 2 inches apart.

Bake for 8 to 10 minutes, or until the edges are lightly golden.

Let the cookies cool on the baking sheet for 2 minutes, then transfer to a wire rack to cool completely.
