Cream the Butter and Sugar: In a mixing bowl, combine softened butter with sugar. Use an electric mixer on medium speed to cream them together until light and fluffy, about 2-3 minutes.

Add Flavorings and Egg Yolk: Mix in vanilla extract and a pinch of salt, then add one egg yolk while continuing to beat until well incorporated.

Incorporate the Flour: Gradually sift in all-purpose flour, mixing on low speed just until the dough comes together.

Chill the Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for 15 minutes.

Preheat the Oven: Preheat your oven to 350°F (175°C) while the dough chills.

Roll and Cut the Dough: Once chilled, roll out the dough to about ¼ inch thickness and use cookie cutters to cut out shapes.

Bake the Cookies: Transfer the cookie sheets to the oven and bake for 10-12 minutes or until edges are lightly golden.

Melt the Chocolate: Melt dark and white chocolate wafers in separate bowls in the microwave in 30-second intervals until smooth.

Decorate the Cookies: Dip cooled cookies into the melted chocolate and add decorations while still wet.

Let Chocolate Set: Allow dipped cookies to sit at room temperature until chocolate hardens.
