Ingredients:
1 cup (2 sticks) unsalted butter, softened
3/4 cup granulated sugar
1/2 cup powdered sugar
1 large egg yolk
1 teaspoon vanilla extract
1/2 teaspoon lemon zest
2 1/2 cups all-purpose flour
1/4 teaspoon salt
Instructions:
- Cream together the butter and sugars: In a large bowl using an electric mixer or a hand mixer, cream together the softened butter and both sugars until light and fluffy, about 3 minutes.
- Beat in the egg yolk, vanilla extract, and lemon zest: Add the egg yolk, vanilla extract, and lemon zest and beat until well combined.
- Gradually add the flour and salt: Add the flour and salt in batches, mixing until just combined. Don't over-mix! The dough will be soft and slightly sticky.
- Chill the dough: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or up to overnight. This helps the dough firm up and prevents spreading during baking.
- Preheat oven and prepare baking sheets: Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.
- Scoop and bake: Using a cookie scoop or a tablespoon, portion the dough onto the prepared baking sheets, leaving about 2 inches between each cookie. If desired, you can flatten the cookies slightly with the back of a spoon or fork.
- Bake for 10-12 minutes: Bake the cookies until the edges are lightly golden brown. Let cool on the baking sheets for a few minutes before transferring to a wire rack to cool completely.
Tips:
- For a richer flavour, use brown sugar instead of granulated sugar.
- Add a pinch of cinnamon or nutmeg to the dough for a warm and cozy twist.
- You can also roll the dough balls in sprinkles or chopped nuts before baking for a festive touch.
- Store leftover cookies in an airtight container at room temperature for up to 3 days. You can also freeze them for longer storage.
