Preheat the oven to 350°F (175°C).

In a mixing bowl, whisk together the flour, baking powder, baking soda, and salt.

In another bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

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

Roll out the dough on a floured surface to about 1/4 inch thick.

Use cookie cutters to cut out shapes and place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.

Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.

Once the cookies are completely cool, use royal icing to decorate as desired.

Sprinkle with additional sprinkles if desired.
