Servings: 12
Ingredients
Cookies
- ½ cup butter softened
- ⅓ cup sugar
- 1 egg yolk
- ½ tsp baking powder
- 1 ¼ cups all-purpose flour
- 1 pinch fine salt
Icing & Decoration
- 1 cup powdered sugar
- 1 egg white
- ½-1 tbsp water as needed
- Black decorating icing
- Mini M&M’s or colorful candy-coated chocolates
Instructions
- Beat the softened butter and granulated sugar together until light and fluffy. Add the egg yolk and mix until fully combined.
- Add the all-purpose flour, baking powder, and salt. Mix gently just until a soft dough forms.
- Wrap the dough tightly in plastic wrap and chill in the refrigerator for 1 hour.
- Roll the chilled dough out to about ⅕-inch (5 mm) thickness. Cut into round circles using a cookie cutter.
- Bake at 350°F (180°C) for 8–10 minutes, until the edges are lightly golden. Allow the cookies to cool completely before decorating.
- Prepare White Icing: Whisk the powdered sugar with the egg white in a bowl. Gradually add a small splash of water until you reach a thick, spreadable consistency.
- Spread a thin, even layer of white icing over each cooled cookie and let it set completely.
- Pipe a wavy line across each cookie using black decorating icing to represent the Christmas light string. Press mini M&M’s along the black line, standing up slightly, to resemble colorful holiday bulbs. Let set before serving.
Notes
Icing Tip: Ensure the white base icing is completely dry and set before piping the black line to prevent bleeding.
