Ingredients:

  • cup (227g) Unsalted Butter, softened
  • /4 cup (150g) Granulated Sugar
  • Large Egg Yolks
  • teaspoon Vanilla Extract
  • cups (375g) All-Purpose Flour
  • /4 cup (30g) Cornstarch
  • /2 teaspoon Fine Sea Salt
  • Powdered (Icing) Sugar for dusting (Optional)
  • Melted Dark Chocolate for dipping (Optional)

Instructions:

  1. In a large bowl, cream the softened butter and sugar together until the mixture is pale, light, and fluffy (about 3–4 minutes).
  2. Beat in the egg yolks one at a time, ensuring each is fully incorporated before adding the next. Mix in the vanilla extract.
  3. In a separate bowl, whisk together the flour, cornstarch, and salt.
  4. Gradually add the dry ingredients to the wet mixture, mixing on low speed only until just combined. Do not overmix.
  5. Turn the dough out onto plastic wrap, form it into a thick disc, wrap tightly, and refrigerate for a minimum of 60 minutes (90 minutes is better).
  6. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  7. Lightly flour a surface. Roll the chilled dough to about 1/4 inch (6mm) thickness. Cut into desired shapes using cookie cutters.
  8. Place cookies onto prepared sheets, leaving about 1 inch between them. Bake for 10–12 minutes, until the edges just begin to turn faintly golden brown.
  9. Let cookies cool on the sheet for 5 minutes, then transfer carefully to a wire rack to cool completely.
  10. Once cool, dust heavily with powdered sugar or dip half of each cookie into melted dark chocolate and let set.
