Step 1: Cream the Butter & Sugar

1. In a large mixing bowl, beat the softened butter and sugar together until light and fluffy (about 2–3 minutes).

2. Add 2 egg yolks and vanilla extract, mixing until fully combined.

Step 2: Add the Dry Ingredients

1. In a separate bowl, whisk together the flour and salt.

2. Gradually add the dry mixture to the wet ingredients and mix until a soft dough forms.

Step 3: Chill the Dough

1. Divide dough in half, flatten into disks, and wrap in plastic wrap.

2. Chill in the refrigerator for at least 1 hour, or until firm enough to roll.

Step 4: Roll and Cut

1. Preheat oven to 350°F (175°C).

2. On a lightly floured surface, roll dough to ¼-inch thickness.

3. Cut into circles using a cookie cutter (2 to 2.5-inch size is ideal).

4. Place cookies 1 inch apart on a parchment-lined baking sheet.

Step 5: Egg Wash & Bake

1. In a small bowl, whisk the remaining egg yolk with 1 tbsp milk.

2. Lightly brush the tops of the cookies with the egg wash for a golden finish.

3. Optional: Sprinkle with sugar for sparkle.

4. Bake for 12–14 minutes, or until edges are lightly golden.

5. Let cool on the sheet for 5 minutes before transferring to a rack.

Step 6: Cool & Enjoy

1. Once fully cooled, store cookies in an airtight container.

2. Enjoy with coffee, tea, or a glass of milk.
