In a large bowl, cream together the softened butter and granulated sugar using an electric mixer until light and fluffy. This usually takes about 2-3 minutes.
Beat in the egg, vanilla extract, and almond extract (if using) until well combined. Scrape down the sides of the bowl as needed.
In a separate medium 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. Be careful not to overmix; the dough should be soft and pliable.
Load the dough into your cookie press fitted with your desired disc. Press cookies onto ungreased baking sheets, leaving about 1 inch between them.
If desired, decorate the cookies with sprinkles, jimmies, or sanding sugar before baking.
Bake in a preheated oven at 375°F (190°C) for 7-10 minutes, or until the edges are lightly golden. Watch them closely as they can brown quickly.
Let the cookies cool on the baking sheets for a minute or two before carefully transferring them to a wire rack to cool completely.
