1. Cream the Butter and Sugar

   • In a large mixing bowl, beat the softened butter and sugar until light and fluffy.
   • This step incorporates air, giving the cookies a delicate texture.

2. Add the Egg Yolks

   • Mix in the egg yolks one at a time, ensuring each is fully blended before adding the next.
   • The yolks add richness and structure to the cookies.

3. Incorporate the Flour and Salt

   • Gradually add the sifted flour and salt, mixing just until the dough comes together.
   • Do not overmix, as it can make the cookies tough.

4. Chill the Dough

   • Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
   • Chilling helps solidify the butter, preventing the cookies from spreading too much during baking.

5. Shape and Bake

   • Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
   • Roll out the dough to ¼-inch thickness and use a cookie cutter to create shapes.
   • Bake for 12-15 minutes, or until the edges are golden brown.

6. Cool and Serve

   • Let the cookies cool on a wire rack before serving.
   • Enjoy them plain, dusted with powdered sugar, or dipped in chocolate.

💡 Pro Tip: Pair these cookies with a cup of French coffee or tea for the ultimate experience!
