Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.

In a medium bowl, whisk together flour, baking powder, and salt.

In another bowl, beat butter and sugar until light and fluffy. Add eggs and vanilla, mixing well.

Gradually add dry ingredients to wet mixture until dough forms.

Divide dough into portions, color each portion, and roll into logs.

Stack colored logs, lightly roll, then slice into ½-inch thick spirals. Place on prepared sheet.

Optional: sprinkle tops with festive sprinkles.

Bake 12–14 minutes until edges are lightly golden. Cool on wire rack.
