Making Traditional German Butter Cookies is straightforward if you follow these easy steps:

1. Prepare the Dough: In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.
2. Add Egg Yolk: Incorporate the egg yolk and vanilla extract, mixing well until combined.
3. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
4. Mix Dry and Wet Ingredients: Gradually add the dry mixture to the wet ingredients, stirring until the dough comes together.
5. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for 30 minutes. This step is essential for achieving the right texture.
6. Preheat Oven: While the dough chills, preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
7. Roll and Shape: After chilling, roll out the dough on a lightly floured surface to about ¼ inch thick. Use cookie cutters to cut out desired shapes.
8. Place on Baking Sheets: Carefully transfer the cookie shapes onto the prepared baking sheets, spacing them about 1 inch apart.
9. Bake: Place the baking sheets in the preheated oven and bake for 10-15 minutes, or until the edges turn lightly golden.
10. Cool: Remove cookies from the oven and let them cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
11. Decorate (Optional): Once cooled, you can dust with powdered sugar or drizzle with chocolate icing for a little extra flair.
