Christmas Kitchen Sink Cookies

These Christmas kitchen sink cookies started the year I decided to clean out my baking cabinet before December hit.

I pulled out half full bags of M&Ms, white chocolate chips, pretzels, and every sprinkle known to man, and instead of putting them back, I tossed them into one big batch of cookie dough. The pan that came out of the oven looked wild, but the kids circled like little cookie critics and grabbed one anyway.

They took a bite, looked at each other, and then started calling them the “Christmas everything cookies”. Now they are a non negotiable part of our holiday baking day. We scoop dough, press extra candies on top, and watch them puff and settle into thick, chewy cookies that taste like every good thing from the snack shelf mixed into one bite.

this Recipe

• All purpose flour, baking soda, and cornstarch: These give structure and help the cookies stay thick and soft instead of spreading flat.
• Melted unsalted butter: Melted butter makes mixing by hand easy and gives the cookies rich, chewy centers.
• Brown sugar and granulated sugar: Brown sugar brings moisture and caramel flavor, while white sugar helps the edges crisp a little.
• Eggs and vanilla: Two eggs add richness and help bind all the mix ins, and vanilla rounds out the flavor.
• Red and green M and Ms: These give classic Christmas cookie energy and add pops of color in every bite.
• White chocolate chips: They melt into creamy pockets that balance the salty crunch from the pretzels.
• Chopped pretzels: These add little bursts of salt and crunch that keep the cookies from being too sweet.
• Holiday sprinkles: Jimmies or nonpareils make the tops sparkle and scream Christmas on the cookie plate.

Step By Step: How To Make Christmas Kitchen Sink Cookies

You do not need a stand mixer or special tools for this cookie recipe. A whisk, a spoon, and a couple of baking sheets will handle it just fine.

Whisk The Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt until everything looks evenly combined. Set this bowl aside so it is ready when your wet ingredients are mixed.

This quick step keeps any pockets of baking soda from hiding in the dough and gives you evenly risen cookies.

Stir Together The Wet Ingredients

In a large bowl, whisk the melted butter with the brown sugar and granulated sugar until the mixture looks smooth and glossy. Add the eggs one at a time, whisking after each, then stir in the vanilla.

You want everything well blended, but there is no need to whip a lot of air into the mixture. Chewy cookies start with a smooth but not foamy base.

Bring The Dough Together

Tip the dry ingredients into the wet bowl and gently stir with a wooden spoon or spatula until no dry streaks of flour remain. Stop as soon as the dough comes together.

Overmixing at this point can make cookies tough, so it is fine if the dough still looks a bit rustic before you add the mix ins.

Fold In All The Mix Ins

Add the M and Ms, white chocolate chips, chopped pretzels, and holiday sprinkles to the bowl. Use your spatula to fold everything in until the goodies are scattered evenly through the dough.

If you want picture perfect cookies, hold back a small handful of candies and sprinkles to press onto the tops right before baking.

Scoop And Bake

Line baking sheets with parchment paper, then scoop rounded tablespoons of dough and place them a couple of inches apart. If you have time, you can chill the scooped dough for thicker cookies, but it is not required.

Bake until the edges are lightly golden and the centers look just set. The cookies will puff in the oven and then settle into thick, chewy rounds as they cool.

Tips For The Best Christmas Kitchen Sink Cookies

These cookies are meant to be fun and relaxed, but a few small choices can make them look and taste bakery level without much extra work.

• Measure flour lightly: Spoon it into your measuring cup and level it off so the dough does not turn stiff or dry.
• Do not overbake: Pull the cookies when the centers still look slightly soft. They will finish setting on the hot pan.
• Chill for extra thickness: If your kitchen is warm, chill the scooped dough for 30 minutes for tall, bakery style cookies.
• Pretty tops: Press extra M and Ms and sprinkles onto each dough ball before baking so the decorations stay visible.

Festive Mix In Ideas

The whole point of a kitchen sink cookie is to use what you love. Here are a few holiday friendly ideas if you want to mix things up from one batch to the next.

• Chopped Andes mints for a chocolate mint twist.
• Crushed candy canes for crunch and peppermint flavor.
• Pistachios or pecans for a nutty, slightly salty bite.
• Toffee bits for caramel flavor and extra chew.
• Mini peanut butter cups for a more indulgent kitchen sink cookie.

Storage And Freezing

These cookies keep their chewy texture well, which makes them perfect for cookie trays, gifting, and mailing. Here is how to store them without losing that soft center.

Method	Suggestion
Room temperature	Store cooled cookies in an airtight container for up to 1 week. Tuck in a slice of bread to help keep them soft.
Freezing baked cookies	Freeze in a single layer, then move to a freezer bag for up to 3 months. Thaw at room temperature.
Freezing dough balls	Freeze scooped dough on a tray, then store in a bag. Bake from frozen, adding a couple of extra minutes.

Christmas Kitchen Sink Cookies FAQs

Do I really need all of these mix ins?

No, you can absolutely scale back. The cookie base works even if you only add chocolate chips and M and Ms. Think of the rest as a fun way to use up open bags in your pantry.

Why are my cookies spreading too much?

If your cookies spread flat, the butter may have been very hot or there was a bit too little flour. Let the dough rest in the fridge for 30 minutes and make sure you measure the flour with a light hand for the next batch.

Can I make these cookies ahead for a cookie exchange?

Yes, you can bake them a day or two in advance and store them airtight, or freeze dough balls and bake them fresh the morning of your event. They stay chewy and pretty, which makes them perfect for holiday cookie platters and swaps.

Can I double the recipe?

Yes, this recipe doubles well. Use a very large bowl so you have room to stir in all the mix ins and bake in batches to keep the oven heat steady.
