Ingredients You’ll Need for Kitchen Sink Cookies

The beauty of these Christmas kitchen sink cookies is that they’re made with everyday baking staples plus fun mix-ins. Here’s what you’ll need:

For the cookie dough:

• Salted butter (3/4 cup, softened) The base of our rich, flavorful cookies
• Light brown sugar (3/4 cup, packed) Adds moisture and that lovely caramel flavor
• Granulated white sugar (1/4 cup) Helps create those crispy edges
• Egg yolks (2, at room temperature) Makes cookies extra rich and tender
• Vanilla bean paste or extract (2 tsp) Adds warmth and depth of flavor
• All-purpose flour (1 1/2 cups, spooned and leveled) The structure of our cookies
• Baking powder (1/2 tsp) Helps cookies rise slightly
• Baking soda (1/2 tsp) Creates that perfect chewy texture
• Salt (1/2 tsp) Balances all the sweet flavors

For the mix-ins:

• Red and green M&M’s (1/2 cup) Classic holiday colors and chocolate flavor
• White chocolate chips (1/3 cup) Adds creamy sweetness
• Pretzel pieces (1/3 cup) That essential salty crunch
• Potato chip pieces (1/3 cup) Unexpected but SO good!
• Red and green jimmies (2 tbsp) Extra festive sparkle

A few quick notes on ingredients: Make sure your butter is truly softened (not melted) for the best texture. I always bring my eggs to room temperature by letting them sit in warm water for five minutes. And please, measure your flour correctly by spooning and leveling!

How to Make the Best Christmas Kitchen Sink Cookies

Making these festive M&M cookies is straightforward and fun. Here’s how to create cookie perfection:

Prepare your workspace

Start by preheating your oven to 350 degrees F. Line two baking sheets with parchment paper and set them aside. Trust me, parchment paper makes cleanup SO much easier and prevents sticking.

Cream the butter and sugars

Add your softened salted butter, light brown sugar, and granulated sugar to a large mixing bowl. Using an electric mixer, cream them together for about two minutes. You’re looking for a light, fluffy mixture that’s almost doubled in volume.

This step is super important! Properly creamed butter and sugar creates those air pockets that make cookies tender.

Add eggs and vanilla

Next, add your egg yolks and vanilla to the butter mixture. Mix on medium speed for two full minutes. The mixture should become pale in color and noticeably fluffy. This extra mixing time really makes a difference in the final texture.

Mix in dry ingredients

Now add your flour, baking powder, baking soda, and salt. Mix just until everything is combined. Be careful not to overmix here, or your cookies might turn out tough.

Fold in the fun stuff

Here’s where these cookies get exciting! Add all your mix ins: the M&M’s, white chocolate chips, pretzel pieces, potato chip pieces, and sprinkles. Use a spatula to gently fold everything together until evenly distributed.

Shape and arrange

Scoop your dough into 20 equal balls. I use a cookie scoop to keep them uniform. Arrange them about two inches apart on your prepared baking sheets. They’ll spread a bit while baking, so give them room!

Here’s my secret trick: Press a few extra M&M’s, pretzels, or chocolate chips on top of each dough ball before baking. This makes them look absolutely gorgeous when they come out of the oven.

Bake to perfection

Bake for 10-12 minutes depending on your texture preference. Ten minutes gives you chewy cookies with softer centers, while 12 minutes creates slightly crisper edges. I usually go for 11 minutes myself.

Optional shaping trick

Want bakery-perfect round cookies? As soon as they come out of the oven, use a large circular cookie cutter to swirl around each cookie. This gently pushes the edges together into a perfect circle. It’s completely optional but makes them look professionally made!

Cool properly

Let the cookies cool on the baking sheets for five minutes. This cooling time allows them to set up properly. Then transfer them to a cooling rack for another 10 minutes before diving in.

Storage Tips for Your Christmas Cookies

Store your Christmas kitchen sink cookies in an airtight container at room temperature for up to three days. They’ll stay soft and chewy if you tuck a piece of bread in the container with them.

For longer storage, freeze baked cookies in a freezer-safe container for up to three months. Let them thaw at room temperature for about 30 minutes before enjoying.

You can also freeze the raw cookie dough balls! Place them on a baking sheet and freeze until solid, then transfer to a freezer bag. Bake from frozen, adding just 1-2 extra minutes to the baking time.
