Preheat your oven to 350°F (175°C). Gather your ingredients, including both Pillsbury sugar cookie dough and shape cookie dough, along with non-stick parchment paper, cookie cutters, and a baking sheet.

Roll out the Pillsbury sugar cookie dough on a lightly floured surface to a thickness of about 1/4 inch. Use cookie cutters to create fun shapes.

Bake shaped cookies in the preheated oven for 8-10 minutes, or until edges are just golden. Cool for 5 minutes on the baking sheet, then transfer to a wire rack.

Roll out the Pillsbury shape cookie dough and cut shapes for stacking. Place one on top of each sugar cookie and decorate with colorful nonpareils.

Allow decorated cookies to set for at least 15 minutes to ensure sprinkles adhere properly before storing.
