  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter, softened Use soft, room-temperature butter, not melted.
  • 1 cup granulated sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 1/4 cup buttermilk Substitute with 1/4 cup milk + 1 teaspoon lemon juice if needed.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.

Mixing

  • In a large bowl, beat the softened butter and granulated sugar for 2–3 minutes until light and fluffy.
  • Mix in the egg, vanilla extract, and buttermilk until smooth and uniform.
  • Gradually add the dry ingredients to the wet mixture, folding until just combined.

Coloring and Shaping

  • Divide the dough into two portions. Add pink gel coloring to one half and blue gel coloring to the other, kneading until the color is evenly distributed.
  • Take small amounts of both doughs, about 1½-inch ball size, and gently roll them together to create a marbled effect.
  • Form into 1½-inch balls and place them 2 inches apart on the prepared sheet.

Baking

  • Bake for 10–12 minutes, until the edges are just golden and the centers are slightly underdone.
  • Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
