Step-by-Step: How to Make Christmas Kitchen Sink Cookies

  1. Cream the butter and sugars
    Get that butter nice and soft, then beat it with the sugars until fluffy. It’s the secret to a chewy cookie.
  2. Add in the eggs and vanilla
    Mix well until everything’s combined.
  3. Stir in dry ingredients
    Flour, baking soda, and salt go in next. Don’t overmix, just until everything’s incorporated.
  4. Fold in the mix-ins
    This is the fun part—throw in all those glorious Christmas goodies! Pretzels, M&Ms, marshmallows, chocolate chips—you name it.
  5. Scoop and chill
    Scoop out balls of dough and chill them in the fridge for at least an hour. Trust me, chilling gives them that perfect texture.
  6. Bake at 350°F
    Bake the cookies for 10-12 minutes, or until the edges are just golden. Don’t overbake—you want the centers to stay soft and chewy.
  7. Cool and enjoy
    Let them cool (if you can wait) and dig in!

How to Customize Your Christmas Kitchen Sink Cookies

One of the best things about Christmas Kitchen Sink Cookies is how easily customizable they are! You can take these festive treats in so many directions depending on your personal preferences. Let’s dive deeper into some ways to create your perfect batch:

1. Chocolate Lovers’ Dream

Want a cookie that’s all about chocolate? Go ahead and double or even triple the chocolate elements. Here’s how:

  • Extra Chocolate Chips: Mix in semi-sweet, milk, and dark chocolate chips for a rich, layered chocolatey bite.
  • White Chocolate Drizzle: After baking, drizzle the cookies with melted white chocolate for an extra festive touch. The contrast of the white chocolate with darker chunks in the cookie gives it a gourmet finish.
  • Add Cocoa Powder: Incorporate a few tablespoons of cocoa powder into the dough to make a chocolate base. Chocolate cookies with chocolate mix-ins? Heaven for chocoholics!

2. Salty-Sweet Sensation

Prefer the addicting combo of salty and sweet? Balance the sugary mix-ins with salty ingredients to create a flavor explosion:

  • Pretzels & Potato Chips: These are the MVPs of salty-sweet cookies. Crush them up for a crunchy texture that contrasts with the softness of the dough.
  • Salted Caramel: Swap out regular caramel pieces for salted caramel chunks. When they melt in the oven, you get pockets of gooey, salty-sweet perfection.
  • Peanut Butter Pretzels: For something truly unique, add peanut butter-filled pretzels to the mix. It’s a hit of salt, crunch, and nutty goodness all in one.

3. Flavor Boost with Pudding Mix

To keep your cookies soft, adding pudding mix to your dough is a great trick. But it also brings extra flavor to the table! Here are some festive pudding options:

  • Butterscotch: Butterscotch pudding mix brings a caramel-like depth, perfect for the holidays.
  • Vanilla or French Vanilla: This adds a creamy, subtle sweetness that pairs well with the more complex flavors in your mix-ins.
  • Chocolate Pudding: Want to amp up the chocolate even more? Chocolate pudding mix keeps cookies soft and adds a decadent richness.

4. Festive Holiday Spices

Want to make your Christmas Kitchen Sink Cookies even more holiday-ready? A dash of warm spices can turn a regular cookie into a Christmas delight:

  • Cinnamon: A pinch of ground cinnamon adds warmth and pairs beautifully with the sweetness of your mix-ins.
  • Nutmeg: This spice screams Christmas. Just a little nutmeg can elevate your cookies into something magical.
  • Ginger or Allspice: A touch of ginger or allspice can add a gingerbread-like flavor, making your cookies feel even more festive.

5. Holiday-Themed Mix-ins

Adding color and extra festiveness to your cookies can be simple with some creative mix-ins:

  • Red & Green M&Ms: Swap out the regular M&Ms for holiday-themed ones to bring that pop of Christmas color.
  • Crushed Candy Canes: These add both color and a minty twist, giving your cookies a refreshing bite.
  • Sprinkles: Holiday-colored sprinkles can be folded into the dough or sprinkled on top for an extra festive touch.

Baking Tips for Perfect Christmas Kitchen Sink Cookies

Baking the perfect Christmas Kitchen Sink Cookies can require a little finesse. Sometimes, things don’t go quite as planned—don’t worry! Here’s how to troubleshoot common cookie issues:

1. Why Are My Cookies Flat?

Flat cookies can be a real bummer, but the good news is, there’s an easy fix:

  • Chill the Dough: If your cookies spread too much, the butter may have melted too quickly. Chilling the dough for at least an hour before baking helps solidify the fats and keeps the cookies from spreading.
  • Check the Butter Temperature: Make sure your butter is soft, but not melted. If it’s too warm, it can cause the cookies to spread excessively.
  • Adjust the Baking Soda: If your cookies are still too flat, try adding a little extra flour or reducing the sugar slightly to help them hold their shape.

2. How to Make Them Softer

If your cookies come out a bit crunchy and you prefer a chewy texture:

  • Bake for Less Time: Take them out just as the edges turn golden, but the centers remain soft.
  • Add More Brown Sugar: Brown sugar has more moisture than white sugar, which can keep your cookies chewy.

3. How to Keep Dough From Spreading

Spreading too much? Add a little more flour or reduce the sugar. Both of these ingredients affect the structure of the cookie, and adjusting the balance can help prevent excessive spreading.

Gluten-Free & Vegan Christmas Kitchen Sink Cookies

Whether you’re accommodating dietary restrictions or simply want to try something different, these cookies can easily be made gluten-free or vegan.

Gluten-Free Version:

  • Gluten-Free Flour: Swap out regular flour for a gluten-free blend. Be sure to check that your mix-ins, like pretzels or M&Ms, are gluten-free as well.
  • Xanthan Gum: If your gluten-free flour blend doesn’t already contain xanthan gum, add a pinch. This helps mimic the elasticity and chewiness of traditional wheat-based cookies.

Vegan Version:

  • Butter Substitute: Replace the butter with a vegan margarine or plant-based butter. It behaves just like the real thing.
  • Egg Replacement: Use flax eggs—combine 1 tbsp of ground flaxseed with 3 tbsp of water for each egg you’re replacing. Let it sit for a few minutes to thicken, then mix into your dough.
  • Vegan Chocolate and Pretzels: There are plenty of vegan options for chocolate chips and pretzels, so you won’t be missing out on any of the fun mix-ins!

Storing & Freezing Christmas Kitchen Sink Cookies

The flexibility of these cookies makes them perfect for making ahead of time. Here’s how to store them for maximum freshness:

At Room Temperature:

Store the baked cookies in an airtight container for up to a week. Keep them in a cool, dry place to prevent them from getting stale.

Freezing Baked Cookies:

Once baked and cooled, freeze the cookies in a single layer on a baking sheet. Once frozen, transfer them to a freezer-safe bag. They’ll last up to three months in the freezer. To serve, just let them thaw at room temperature for 15-20 minutes.

Freezing Cookie Dough:

Scoop out your dough into individual balls and freeze them on a baking sheet. Once frozen, store the balls in a freezer bag. When ready to bake, place the frozen dough balls on a baking sheet and bake straight from frozen. Just add a few minutes to the baking time.
