1-Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper to prevent sticking.

2-In a large bowl, cream together the softened butter and sugar until light and fluffy. For vegan or low-calorie options, use respective substitutes here.

3-Beat in the egg (or flaxseed egg) and vanilla extract until well combined.

4-Whisk together the flour, baking powder, and salt in a separate bowl. Gradually add this dry mixture to the wet ingredients, mixing just until combined.

5-Fold in the festive sprinkles gently to distribute evenly without melting their color.

6-Scoop dough into medium-sized balls, place them on the baking sheets spaced apart, and slightly flatten each ball with your hand.

7-Bake for 10-12 minutes or until edges are lightly golden. Adjust timing slightly for gluten-free dough as needed.

8-Remove from oven and let cookies cool on baking sheet for 5 minutes before transferring them to a wire rack.

9-Stack the cooled cookies carefully for serving or packaging. These cookies can be customized with additional sprinkles or icing as desired.
