Christmas Kitchen Sink Cookies are the cookie I bake when I want one tray to feel loud, cheerful, and a little chaotic in the best way. You get soft centers, crisp edges, melty chocolate, candy crunch, and salty bits from pretzels and potato chips.
The dough is simple, but the texture depends on two small choices. Do not crush the mix-ins into dust, and give the scooped dough time to chill before it hits the oven.
The Holiday Mix-In Pile
Use a sturdy cookie dough and mix-ins that bring different textures. Big broken pieces are better than crumbs because you want visible candy, salty crunch, and pockets of chocolate in every cookie.
- Unsalted butter. Gives the cookies rich flavor and lets you control the salt.
- Brown sugar. Keeps the centers chewy and adds a light caramel note.
- Granulated sugar. Helps the edges bake crisp and lightly golden.
- Eggs. Bind the dough and give the cookies enough structure for all the mix-ins.
- Vanilla extract. Rounds out the chocolate and candy flavors.
- All-purpose flour. Builds the base of the cookie. For weight checks, the King Arthur ingredient weight chart is a useful baking reference.
- Cornstarch. Softens the crumb and helps the cookies stay tender.
- Baking soda and baking powder. Give the dough lift without making the cookies cakey.
- Holiday M&Ms. Add color, candy crunch, and chocolate in one handful.
- Chocolate chips. Melt into the dough and make the cookies taste fuller.
- White chocolate chips. Add creamy sweetness against the salty pieces.
- Pretzels. Bring a crisp snap and salty bite.
- Ridged potato chips. Add delicate crunch and a salty finish.
- Toffee bits. Give little buttery crunches through the middle.
- Holiday sprinkles. Make the cookies look festive without changing the dough much.
Bake Them Thick and Chewy
- Cream the butter. Beat the softened butter with both sugars until lighter and fluffy, about 2-3 minutes. This helps the cookies bake with soft centers instead of dense middles.
- Add eggs and vanilla. Mix in the eggs one at a time, then add the vanilla. Scrape the bowl so the butter mixture is even.
- Mix the dry ingredients. Whisk flour, cornstarch, baking soda, baking powder, and salt in a separate bowl. Add it to the butter mixture and mix just until no dry streaks remain.
- Fold in the extras. Stir in M&Ms, chocolate chips, white chocolate chips, pretzels, potato chips, toffee, and sprinkles by hand. Save a few pieces for the tops if you want bakery-style cookies.
- Scoop and chill. Scoop 2-tablespoon dough balls onto a lined baking sheet. Chill for at least 45 minutes so the cookies bake thick.
- Bake and shape. Bake at 350°F for 10-12 minutes, until the edges look set and the centers still look a little soft. Sprinkle with flaky salt, then cool on the pan for 10 minutes.
Keep the Crunch Visible
The main mistake with Christmas Kitchen Sink Cookies is breaking every mix-in too small. Pretzels and chips should be rough pieces, not crumbs. The larger pieces stay visible on top and give the cookie that snacky bite people expect.
When you fold the dough, stop as soon as the mix-ins are scattered through it. Too much mixing can crush the chips and pretzels. I like to press a few extra M&Ms, pretzel bits, and chocolate chips onto each scooped dough ball before chilling. It makes the tops look full without stuffing the dough past what it can hold.
Why Chilling Matters Here
This dough carries a lot. Candy, chips, and pretzels weigh it down, and warm butter makes the cookies spread before the centers set. A short chill gives the flour time to absorb moisture and firms the dough enough to hold its shape.
You do not need to chill overnight. Forty-five minutes works well for a same-day bake. If the dough has chilled for several hours and feels rock hard, let it sit on the counter for 10 minutes before baking.

Smart Swaps for Cookie Boxes
Think of the mix-ins as a balance. You want chocolate, crunch, color, and salt. If you remove potato chips, add more pretzels or chopped salted nuts. If you skip toffee, chopped caramels or butterscotch chips work well, but keep sticky pieces tucked away from the cookie edges.
For a nut-free tray, check labels on candy and toffee before baking. For a less sweet cookie, use dark chocolate chips and leave out the white chocolate. If you want more holiday color, add red and green sanding sugar on top after baking while the cookies are still warm.
Storage and Freezer Timing
Once the cookies are completely cool, store them airtight at room temperature for 3-4 days. A small piece of sandwich bread in the container can help keep the cookies soft, but remove it once it dries out.
For make-ahead baking, freeze the scooped dough balls. Put them on a tray until firm, then move them to a freezer bag. The FoodSafety.gov storage chart is a helpful reference for freezer planning. These cookies also fit nicely beside Christmas Gooey Cookies and Buttery Pecan Snowball Cookies in a holiday tin.
Serving Them Without Fuss
These cookies are at their best when they have cooled enough for the chocolate to settle but still taste fresh from the oven. Give them at least 20 minutes on a rack before stacking them on a platter or packing them into boxes.
If you are serving them at a party, add a small bowl of extra pretzels or salty popcorn nearby. It sounds simple, but that little salty side keeps the cookie tray from feeling too sweet. A few cookies also make a good ice cream sandwich if you freeze them first so they hold their shape.
Summary
These loaded holiday cookies are easy to customize and hold well for cookie boxes, parties, and make-ahead baking.
FAQs
- Why are they called kitchen sink cookies?
The name comes from the idea of adding almost everything except the kitchen sink. In this version, that means chocolate, M&Ms, pretzels, potato chips, toffee, and sprinkles folded into one chewy cookie dough.
- Do I have to chill the dough?
Yes, at least 45 minutes is worth it. Chilling firms the butter and hydrates the flour, so the cookies bake thicker and taste more developed instead of spreading into thin, crunchy rounds.
- Can I swap the mix-ins?
Absolutely. Keep the total mix-ins close to the recipe amount, then trade in chopped caramels, peanut butter chips, butterscotch chips, pecans, or crushed peppermint. If you use sticky caramel pieces, press them into the center of the dough balls so they do not leak and burn on the pan.
- How should I store Christmas Kitchen Sink Cookies?
Store cooled cookies in an airtight container at room temperature for 3-4 days. For longer storage, freeze baked cookies between sheets of parchment for up to 2 months, then thaw at room temperature.
- Can I freeze the cookie dough?
Yes. Scoop the dough first, chill the balls until firm, then freeze them in a sealed bag. Bake from frozen at 350°F and add 1-3 minutes to the bake time.
- How do I keep the cookies round?
Use a cookie scoop so every dough ball is similar in size. Right after baking, slide a round cutter or wide glass around each warm cookie to nudge the edges into a neat circle.
- What can I serve with these cookies?
They are rich, so they pair well with coffee, cold milk, hot cocoa, or a simple fruit plate. For a holiday cookie tray, place them beside softer cookies and snowball-style cookies so the textures feel varied.
