The beauty of kitchen sink cookies is that there are no strict rules. If it sounds good to you, it probably works. For the Christmas twist, aim for ingredients that bring in the season’s flavors and colors. Red and green sprinkles, peppermint chunks, pretzels for crunch, and white or milk chocolate chips all shine in this dough. Don’t forget a sprinkle of sea salt on top—it elevates every single bite.

Ingredients for the Christmas Kitchen Sink Cookies

These cookies are all about the mix-ins, but the base dough is where the magic starts. It’s buttery, rich, and holds together all your favorite festive flavors.

Unsalted Butter – Provides the rich, creamy foundation for the dough and ensures a soft texture.

Brown Sugar – Adds a deep, molasses-like sweetness and helps with chewiness.

Granulated Sugar – Balances the brown sugar with a clean, sweet note and helps the cookies spread.

Egg + Egg Yolk – These bind everything together while adding moisture and richness.

Vanilla Extract – Enhances all the flavors in the dough and mix-ins.

All-Purpose Flour – The structure of your cookie starts here.

Baking Soda – Helps the cookies rise just enough while keeping a chewy center.

Salt – Balances the sweetness and enhances flavor depth.

Pretzels – Crushed for a salty crunch that contrasts beautifully with sweet elements.

White Chocolate Chips – Add creamy sweetness and a festive snow-white color.

Red and Green M&Ms or Sprinkles – For colorful bursts and classic holiday charm.

Crushed Candy Canes – Adds a minty crunch that screams Christmas.

Toffee Bits or Chopped Pecans (optional) – These add rich, nutty undertones for extra texture.

How To Make the Christmas Kitchen Sink Cookies

Step 1: Cream the Butter and Sugars

Start by beating the unsalted butter, brown sugar, and granulated sugar together until the mixture is light and fluffy. This creates air pockets that help the cookies stay soft and chewy.

Step 2: Add Wet Ingredients

Mix in the egg, egg yolk, and vanilla extract. The extra yolk adds richness and chewiness to the cookie base.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet mixture and stir until just combined.

Step 4: Fold in the Mix-Ins

Gently fold in your crushed pretzels, white chocolate chips, M&Ms, sprinkles, and candy canes. Be careful not to overmix.

Step 5: Chill the Dough

Let the dough chill for at least 30 minutes. This helps the flavors meld and keeps the cookies from spreading too much.

Step 6: Bake to Perfection

Scoop the dough onto a lined baking sheet and bake at 350°F for about 10-12 minutes. The edges should be golden, and the centers just set. Finish with a light sprinkle of sea salt while they’re still warm.

How to Serve and Store Christmas Kitchen Sink Cookies

These cookies are best served slightly warm with a glass of cold milk or a hot cup of cocoa. Their texture and flavor are at peak deliciousness fresh from the oven or gently reheated. They make excellent edible gifts too—just pack them in a festive tin or cellophane bag.

This recipe yields about 24 medium-sized cookies. Store them in an airtight container at room temperature for up to 5 days. To freeze, place baked cookies in a single layer and transfer to a freezer-safe bag once solid. They can last up to 3 months frozen.
