Christmas Light Cookies Ingredients
- Flour – serves as the base for your sugar cookies.
- Baking Powder – ensures your cookies are light and tender.
- Salt – balances out the sweet flavors.
- Butter – makes your cookies nice and moist and gives them a delicious buttery flavor.
- Sugar – to sweeten your cookies.
- Egg Yolk – acts as a binding agent for the cookie dough.
- Vanilla – adds some extra sweetness and a delicious vanilla flavor.
- Almond Extract – works well with the vanilla flavoring and gives your cookies another layer of flavor.
- Powdered Sugar – when mixed with a few wet ingredients, powdered sugar forms the perfect royal icing!
- Fresh Lemon Juice – gives your icing a balance of sweet and tart.
- Egg White – ensures that the icing will dry hard after it’s been spread onto the cookies.
Cookie Decoration Ingredients
- Small Tube of Black Icing – this will act as the “strings” for the string lights.
- M&M’s – cut in half, M&Ms are the perfect shape to be colorful light bulbs!
How to Make Christmas Light Cookies
- Preheat the oven to 350 degrees. In a medium or small bowl, whisk together flour, baking powder, and salt.
- In a separate bowl, cream together the softened butter and sugar until light and fluffy. Add the egg yolk, vanilla, and almond extract, then mix until combined.
- Add the dry ingredients to the wet in portions, mixing just until combined.
- Turn the dough out onto a floured surface and knead, then collect into a ball. Roll out the dough into a ½ inch thick layer.
- Using a cookie cutter, cut out 12 circles from the dough.
- Place cookies on a prepared baking sheet with parchment paper and bake the cookies for 10-12 minutes, or until lightly golden. Transfer to a wire rack to cool completely.
How to Make Icing and Decorate
- Combine lemon juice with egg white and powdered sugar and mix until smooth.
- Spread the royal icing on each cookie, either by using a spatula or by flooding the cookies. An offset spatula like this works great for this. Allow the icing to harden entirely.
- Decorate by squeezing lines of black frosting on top of the hardened icing. Cut the M&Ms in half and place them at even intervals to look like Christmas lights. Serve alongside Christmas Tree Spinach Dip Breadsticks or a Christmas Tree Cake for a cute and festive snack!
What does it mean to flood a cookie?
This technique is done specifically with royal icing or other thin frostings. The technique involves creating a dam of icing and then “flooding” the cookie with a consistent layer of icing, which can be easier than spreading icing on and also yields more clean and consistent results.
How do you flood Christmas cookies?
Transfer your royal icing to a piping bag. Cut a very small hole and outline the cookies with icing, ensuring that this outline dries before continuing.
Then cut a slightly larger hole and squeeze a larger amount of frosting into the outline, ensuring there’s enough to cover the surface. You may need to use an offset spatula or other flat tool to help the frosting spread evenly.
Do I have to use royal icing for these Christmas Light Cookies?
Not necessarily! It provides a nice solid base for the string light decorations, but you could also use a softer frosting like buttercream or vanilla frosting if you want a softer topping for your cookies.
Popular Variations and Substitutions
- Use a Christmas light cookie cutter shape to add another layer of decoration to your cookies.
- If you don’t want to bother cutting the M&Ms, mini M&Ms may be a good substitute if embedded in the royal icing so they have the correct shape. Place the minis in the white frosting before it dries, then once hardened, pipe the lines of darker frosting.
- The light of the strings can also be made with some royal icing dyed with black food coloring, or you can melt some chocolate wafers and pipe that on instead if you want even more chocolate flavor.
- If you’re feeling adventurous, try piping some green frosting using a fun shaped frosting tip to look like Christmas tree branches among the lights.
- Serve alongside another snack like Dark Chocolate Peppermint Popcorn or a festive cocktail like our Cranberry Apple Mimosas.
