Ingredients
The beauty of Kitchen Sink Cookies lies in their versatility. While I’ll provide a base recipe, feel free to get creative and customize it to your liking. Don’t be afraid to add, subtract, or substitute ingredients based on what you have available.
- All-Purpose Flour: 2 1/4 cups. Provides the structure of the cookie. For a slightly chewier cookie, use bread flour.
- Baking Soda: 1 teaspoon. Helps the cookies rise and gives them a soft texture.
- Salt: 1 teaspoon. Enhances the flavors of the other ingredients.
- Unsalted Butter: 1 cup (2 sticks), softened. Adds richness and flavor. Make sure it’s properly softened for easy creaming.
- Granulated Sugar: 3/4 cup. Adds sweetness and helps with browning.
- Brown Sugar: 3/4 cup, packed. Adds moisture, chewiness, and a caramel-like flavor. Light or dark brown sugar works.
- Eggs: 2 large. Bind the ingredients together and add richness.
- Vanilla Extract: 2 teaspoons. Enhances the overall flavor.
- Chocolate Chips: 1 cup (mix of milk, semi-sweet, or dark). Everyone loves chocolate!
- Pretzels: 1 cup, broken into small pieces. Adds a salty crunch.
- Chopped Nuts: 1 cup (walnuts, pecans, or almonds). Adds texture and nutty flavor.
- Toffee Bits: 1/2 cup. Adds a buttery, caramel-like flavor and a bit of crunch.
- Optional Mix-ins: 1 cup (chopped Christmas candies, dried cranberries, shredded coconut, oats, potato chips). This is where you can really get creative!
Ingredient Science & Substitutions:
- Flour: If you want a gluten-free option, use a 1:1 gluten-free all-purpose flour blend.
- Butter: Margarine can be used in a pinch, but butter will provide the best flavor.
- Sugar: You can experiment with using all brown sugar for an even chewier cookie, but be aware it will affect the spread.
- Mix-ins: Don’t be afraid to get creative! Use up leftover Halloween candy, crushed peppermint candies, or even potato chips for a salty-sweet twist.
Expert Tips
After years of baking these cookies, I’ve learned a few tricks to ensure they turn out perfectly every time. These are some tips I’ve found helpful while testing the recipe!
- Don’t overmix the dough: Overmixing develops the gluten in the flour, leading to tough cookies. Mix until just combined.
- Chill the dough: Chilling the dough for at least 30 minutes (or even overnight) helps prevent the cookies from spreading too much during baking and intensifies the flavors.
- Use a cookie scoop: A cookie scoop ensures that all your cookies are the same size, so they bake evenly.
- Don’t overcrowd the baking sheet: Give the cookies enough space to spread without touching each other.
- Bake until golden brown: Bake the cookies until the edges are golden brown, but the centers are still slightly soft. They will continue to bake on the hot baking sheet after you remove them from the oven.
- Let them cool completely: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This prevents them from breaking.
Storage & Substitutions
These Christmas Kitchen Sink Cookies are best enjoyed fresh, but they can also be stored for later. Here’s how:
- Storage: Store the cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze them for up to 2 months.
- Freezing: To freeze the cookies, place them in a single layer on a baking sheet and freeze until solid. Then, transfer them to a freezer-safe bag or container.
- Reheating: Thaw the cookies at room temperature before serving. You can also warm them slightly in the oven for a few minutes to make them extra gooey.
More Substitution Ideas:
- Vegan Option: Substitute the butter with vegan butter and the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg).
- Nut-Free Option: Omit the nuts or substitute them with sunflower seeds or pumpkin seeds.
- Spice it Up: Add a pinch of cinnamon, nutmeg, or cloves to the dough for a warm, festive flavor.
- Citrus Zest: Add orange or lemon zest to the dough for a bright, fresh flavor.

FAQ
Here are some frequently asked questions about making Christmas Kitchen Sink Cookies:
Why are my cookies flat?
Flat cookies can be caused by a few things: using softened butter that’s too warm, not chilling the dough, or overmixing the dough. Make sure your butter is softened but still cool, chill the dough for at least 30 minutes, and mix until just combined.
Can I use shortening instead of butter?
Yes, you can use shortening instead of butter, but the flavor and texture will be different. Shortening will result in a softer, less flavorful cookie.
How long should I chill the dough?
I recommend chilling the dough for at least 30 minutes, but you can chill it for up to 24 hours. The longer the dough chills, the more the flavors will develop and the less the cookies will spread.
Can I add oats to these cookies?
Yes, you can add oats to these cookies! I recommend using about 1/2 to 1 cup of rolled oats. Add them to the dough along with the other dry ingredients.
What can I use if I don’t have brown sugar?
If you don’t have brown sugar, you can make your own by mixing 1 cup of granulated sugar with 1 tablespoon of molasses. Mix well until the molasses is evenly distributed.
Can I freeze the cookie dough?
Yes, you can freeze the cookie dough. Scoop the dough into individual portions and freeze them on a baking sheet until solid. Then, transfer them to a freezer-safe bag or container. When you’re ready to bake, thaw the dough in the refrigerator overnight.
My cookies are too hard. What did I do wrong?
Overbaking is the most common cause of hard cookies. Be sure to bake them until the edges are golden brown, but the centers are still slightly soft. They will continue to bake on the hot baking sheet after you remove them from the oven.
These Christmas Kitchen Sink Cookies are more than just a recipe; they’re a celebration of the season and a chance to get creative in the kitchen. With endless possibilities for customization, you can create a cookie that’s uniquely yours and perfect for sharing with family and friends.
