Preheat the oven to 375°F (190°C) and line baking sheets with parchment paper or leave them ungreased.

In a small bowl, whisk together flour, baking soda, and baking powder.

In another bowl, beat softened butter and sugar until smooth and fluffy.

Add the egg, vanilla, and almond extract, mixing until fully combined.

Gradually add the dry ingredients, then pour in buttermilk one tablespoon at a time until the dough is soft but not sticky.

Roll teaspoonfuls of dough into small balls, place on the baking sheet, and flatten gently with the bottom of a glass.

Sprinkle with colored sugar or festive sprinkles. Bake for 8–10 minutes until the edges are lightly golden.

Let cool on the sheet for a few minutes, then transfer to a wire rack to cool completely.
