Step 1: Preheat the Oven

Preheat your festive oven to 350°F (175°C) and line your baking sheets with parchment paper to ensure easy cookie removal.

Step 2: Cream Butter and Sugar

In a jolly mixing session, cream together the 1 cup of softened unsalted butter and 1 cup of granulated sugar until the mixture is light and fluffy.

Step 3: Add Egg and Vanilla

Beat in 1 large egg and 2 teaspoons of vanilla extract, fully incorporating them into the mixture and embracing the holiday spirit.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together 2 1/2 cups of all-purpose flour, 1/4 teaspoon of baking powder, and 1/4 teaspoon of salt. Gradually add this dry mixture to the butter mixture to create a smooth dough.

Step 5: Shape the Cookies

Roll the dough into balls and place them on the prepared baking sheets. Get creative with your decorations by adding sprinkles, colored sugar, or nonpareils on top of each ball.

Step 6: Bake the Cookies

Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are just turning golden. Once baked, transfer the cookies to a wire rack to cool down, letting the holiday magic spread throughout the kitchen.
