Baking these Christmas kitchen sink cookies feels like launching straight into the holiday spirit with every handful of mix-ins. Each tray that comes out of the oven is scattered with gooey chocolate, toasted oats, tart cranberries, and crunchy nuts—basically, every treat you love about December bundled into one bite. The best part is how much fun it is tossing together whatever festive bits are in the pantry. No two batches are exactly the same, and that’s what makes this tradition so dear to me and my family during the holidays.
When I first tried this recipe with my kids, we ended up giggling over how many candies we could fit in without the dough falling apart. Now, making these is our favorite December weekend project. Everyone gets to choose their mix-in, and every batch tells a little story about what we loved that year.
Ingredients
- Unsalted butter: softened to room temperature ensures the cookies have just the right amount of moisture for a chewy bite. Always look for fresh, creamy butter for best results.
- Brown sugar: brings in sweetness with depth and molasses notes. Press it firmly into your measuring cup to get just the right amount.
- Granulated sugar: balances the brown sugar and gives a hint of crispness around the edges. For brighter flavor, choose fine-cast sugar.
- Large eggs: bind everything and help the cookies rise. Use fresh eggs for a thick, lofty dough.
- Vanilla extract: infuses a sweet perfume into the entire batch. For the best flavor, pure vanilla is a must.
- All-purpose flour: holds it all together. Spoon and level your flour for accurate measurement so the dough does not get too stiff.
- Baking soda: is the secret agent behind that gentle lift and chewy crumb. Make sure it is fresh for reliable rising.
- Salt: brings out the flavor of both sweet and savory add-ins. Opt for fine sea salt if possible for even distribution.
- Chocolate chips: add melty fun in every mouthful. Sprinkles of semi-sweet keep each bite balanced but use any chocolate you love.
- Oats: create chewy texture and a hearty feel. Old-fashioned or quick oats work as long as they are rolled and not instant.
- Chopped nuts: like walnuts or pecans bring crunch and toasty flavors. Freshly chopped nuts have the best bite and aroma.
- Dried cranberries: offer tartness and jewel-like spots in the cookies. Soft, plump cranberries are ideal though raisins also work beautifully.
- Mini marshmallows: melt into gooey spots of sweetness. Add in just before shaping so they do not dissolve in the dough.
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 350 degrees Fahrenheit or 175 degrees Celsius before you do anything else. The even heat helps your cookies bake up with golden edges and tender centers.
- Cream the Butter and Sugars:
- In a large mixing bowl add the softened unsalted butter packed brown sugar and granulated sugar. Beat with a hand mixer or stand mixer for 2 to 3 minutes until the mixture turns light fluffy and pale. You are looking for a whipped texture that almost doubles in volume.
- Mix in Eggs and Vanilla:
- Crack two large eggs into the bowl and add the vanilla extract. Beat until everything looks silky and unified. The dough will loosen up slightly at this stage.
- Combine Dry Ingredients:
- In a separate bowl whisk together the all-purpose flour baking soda and salt. This ensures that the leavening and seasoning reach every bite.
- Combine Wet and Dry Mixtures:
- Add the dry ingredient blend into your butter-egg mixture a bit at a time. Use low speed on your mixer or a sturdy spatula if mixing by hand. Stir just until the flour disappears for a soft even dough without toughness.
- Fold in Mix-Ins:
- Gently place chocolate chips oats chopped nuts dried cranberries and mini marshmallows into the dough. Use a spatula to fold, turning the dough over itself until each batch of add-ins is evenly scattered but try not to crush the marshmallows.
- Shape and Bake:
- Scoop generous spoonfuls of dough onto a baking sheet lined with parchment paper. Leave a wide space between cookies to let them spread properly. Slide the tray onto the oven’s center rack and bake for 10 to 12 minutes until the cookie edges turn golden but the centers are still soft when touched.
- Cool and Enjoy:
- Rest your cookies right on the baking sheet for about 5 minutes before moving them to a wire rack. This time lets them finish setting so they do not fall apart when picked up. Now they are ready for sharing or sneaking a cozy bite with a holiday mug.

I always look forward to folding in the mini marshmallows. My little one loves watching them puff up and melt in the oven—they become gooey little surprises in every cookie. Last year, my daughter snuck a few extra marshmallows into her batch, and those cookies disappeared before we even packed them up for gifts.
Storage Tips
To keep your cookies fresh store them in an airtight container at room temperature. They stay soft and chewy for days. If you want to keep them longer pop them in the freezer either as shaped dough or fully baked cookies. For best flavor and texture always let cookies cool completely before sealing them away.
Ingredient Substitutions
Feel free to make these cookies your own. No cranberries? Try raisins chopped apricots or dried cherries. If you are out of chocolate chips use white chocolate chunks butterscotch baking bits or even peppermint chips for a seasonal touch. For nuts you can swap in macadamias cashews or sunflower seeds for a nut-free version.
Serving Suggestions
Serve these warm with mugs of hot cocoa cider or a glass of milk. Arrange them on a platter with other holiday treats for dessert buffets or wrap stacks in parchment and twine for sweet homemade gifts. For extra festive flair sprinkle a few colored sprinkles on top before baking.

Cultural and Historical Context
Kitchen sink cookies are a true American classic known for getting their playful name from the idea of tossing in everything but the kitchen sink. Their mix-and-match nature fits right into the holiday tradition of using up bits of this and that to create something extra special for gatherings. These cookies remind me of the community cookie swaps I used to attend—where the wildest mix-ins always sparked the most conversation.
