Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.

Step 2: Whisk the Dry Ingredients

In a medium bowl, whisk together the flour and salt. This ensures even distribution and prevents clumping.

Step 3: Cream Butter and Sugar

Using an electric mixer, beat the softened butter and granulated sugar in a large bowl until light and fluffy. This process aerates the mixture, giving the cookies their tender texture.

Step 4: Add Wet Ingredients

Mix in the egg yolks, vanilla extract, and 1 tablespoon of milk until the mixture is smooth. If needed, scrape down the sides of the bowl to ensure everything is evenly combined.

Step 5: Combine Dry and Wet Ingredients

Gradually add the flour mixture to the wet ingredients. Mix just until combined—overmixing can lead to tough cookies. If the dough feels too stiff, add another tablespoon of milk.

Step 6: Shape the Dough

• For piped cookies, transfer the dough to a piping bag fitted with a star or round tip. Pipe desired shapes onto the prepared baking sheets.
• For rolled cookies, roll the dough into 1-inch balls and flatten slightly with your hand or the back of a fork.

Step 7: Bake the Cookies

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.

Step 8: Decorate (Optional)

Once cooled, dip the cookies in melted chocolate and add sprinkles or edible decorations. Let the chocolate set before serving or storing.
