Ingredients:
- 1 cup (2 sticks) unsalted butter, softened
- 1 ½ cups granulated sugar
- 1 large egg, room temperature
- 2 teaspoons vanilla extract
- 3 cups all-purpose flour, spooned and leveled
- 1 teaspoon baking powder
- ½ teaspoon fine sea salt
- Optional: 2 cups icing sugar (confectioner's sugar)
- Optional: 3–4 tablespoons milk (Whole or 2%)
- Optional: ¼ teaspoon almond or lemon extract
Instructions:
- Prep the Dry Ingredients: Whisk together the flour, baking powder, and salt in a medium bowl. Set aside.
- Cream the Butter and Sugar: In the bowl of a stand mixer, beat the softened butter and granulated sugar on medium speed until the mixture is light, fluffy, and noticeably pale (about 3–4 minutes).
- Add Wet Ingredients: Beat in the large egg and vanilla extract until just combined. Scrape down the sides of the bowl.
- Combine Dry and Wet: Reduce the mixer speed to low. Gradually add the flour mixture, mixing only until the dough just comes together and no streaks of dry flour remain. Do not overmix.
- Divide and Flatten: Turn the dough out onto a piece of parchment paper. Divide the dough into two equal portions. Gently press each portion into a flat disc, about 1-inch thick.
- Crucial Chill: Wrap each disc tightly in cling film or place between two sheets of parchment paper. Refrigerate for a minimum of 90 minutes (or up to 3 days). The dough must be firm.
- Preheat and Prep: Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats. Remove one chilled dough disc from the fridge.
- Roll and Cut: Place the dough between two sheets of parchment paper. Roll the dough out to an even thickness of approximately ¼ inch (6 mm). Use cookie cutters to cut out shapes.
- Transfer and Chill: Carefully transfer the cut shapes to the prepared baking sheets, leaving about 1 inch between them. For best shape retention, place the filled baking sheets into the freezer for 10 minutes before baking.
- Bake and Cool: Bake for 8–10 minutes, rotating the sheets halfway through, until the edges are lightly golden. Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely before decorating.
