Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper.

In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.

In a large bowl, cream together the softened butter and sugar until light and fluffy, using a hand mixer or stand mixer.

Beat in the egg, vanilla extract, and almond extract (if using) until well combined.

Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms.

Divide the dough into three equal portions. Leave one portion plain, mix red food coloring into the second portion, and mix blue food coloring into the third portion.

Scoop small amounts of each colored dough and roll into balls, combining the colors slightly to create a marbled effect.

Roll the balls in white sprinkles or sugar crystals for a festive touch.

Place the dough balls onto the prepared baking sheets, spacing them about 2 inches apart.

Bake in the preheated oven for 8-10 minutes, or until the edges are lightly golden. Be careful not to overbake.

Let the cookies cool on the baking sheets for 2 minutes before transferring them to a wire rack to cool completely.
