The holidays are my favorite time to bake, and Christmas Kitchen Sink Cookies are the kind of treat that came straight from a craving and turned into a tradition. One snowy evening, I had a few leftover ingredients from holiday baking; crushed peppermint, pretzels, chocolate chips, and even red and green M&M’s. Tossed them all into the dough and hoped for the best. What came out of the oven was pure magic.

These cookies quickly became a festive staple at our house. They’re not just sweet, they’re salty, crunchy, chewy, and colorful. It’s like Christmas exploded in cookie form! If you’re someone who loves a cookie that surprises you in every bite, you’re going to fall hard for this one. Whether you’re adding them to a Christmas cookie box or wrapping them up as a homemade gift, they’re guaranteed to spread holiday cheer.

How to Make Christmas Kitchen Sink Cookies

Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
Cream butter and sugars together until fluffy. Add eggs and vanilla; mix well.
In a separate bowl, combine flour, baking soda, and salt. Slowly add to wet ingredients.
Fold in all your mix-ins. Try a combo of red & green M&M’s, chopped pretzels, and white chocolate chips.
Scoop dough (about 2 tablespoons per cookie) onto baking sheets.
Bake for 10–12 minutes or until edges are golden. Let cool on the tray for 5 minutes before transferring.

They’re even better the next day! That said, they never last long in our house. For another soft cookie favorite, don’t miss these Chocolate Thumbprint Cookies.

Tips and Variations for the Perfect Batch

Chill the dough for at least 30 minutes for thicker cookies that don’t spread.
Customize the mix-ins based on what you love: caramel chunks, potato chips, chopped nuts, or even dried cranberries.
Add a sprinkle of sea salt on top before baking for extra flavor contrast.
Use a cookie scoop to get uniform cookies every time.

Frequently Asked Questions

Can I make these cookies ahead of time?
Absolutely. You can refrigerate the dough for up to 72 hours or freeze the cookie balls for up to 3 months.

A mix of chocolate chips, festive candies, pretzels, and toffee bits is classic. Feel free to toss in seasonal extras like peppermint or cranberries.

Can I make them gluten-free?
Yes, substitute with a 1:1 gluten-free flour blend. Just make sure your mix-ins are also gluten-free.
