Ingredients for Best Kitchen Sink Christmas Cookies

You’ll Need:

• 1 cup unsalted butter, softened
• 3/4 cup granulated sugar
• 3/4 cup packed brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup rolled oats
• 1/2 cup mini M&Ms (use red and green for a festive touch)
• 1/2 cup semisweet chocolate chips
• 1/4 cup white chocolate chips
• 1/4 cup pretzels, broken into pieces
• 1/4 cup chopped nuts (walnuts, pecans, or a mix)
• 1/4 cup toffee bits
• 1/4 cup shredded coconut (optional)

Substitutions

• Replace the nuts with sunflower seeds for a nut-free version.
• Use a 1:1 gluten-free baking mix in place of all-purpose flour for a gluten-free option.
• Swap butter for a plant-based spread to make the recipe dairy-free or vegan-friendly (use a vegan egg substitute if making fully vegan).

How to Make Kitchen Sink Christmas Cookies – Step by Step

Step 1: Preheat Your Oven

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or a nonstick liner.

Step 2: Cream the Butter and Sugars

In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy — about 2 to 3 minutes with an electric mixer.

Step 3: Add Eggs and Vanilla

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until incorporated.

Step 4: Mix Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the butter mixture and mix until just combined — avoid overmixing to keep the cookies tender.

Step 5: Add Mix-Ins

Fold in the rolled oats, mini M&Ms, semisweet and white chocolate chips, pretzel pieces, chopped nuts, toffee bits, and shredded coconut (if using). Stir until the mix-ins are evenly distributed.

Step 6: Shape and Bake

Scoop tablespoon-sized portions of dough and place them about 2 inches apart on the prepared baking sheet. Bake for 10–12 minutes, or until the edges are set and lightly golden. The centers may still look slightly soft — they will firm up as they cool.

Step 7: Cool and Enjoy

Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Serve warm or at room temperature.

Helpful Tips

• Chill the dough: For thicker, chewier cookies, chill the dough for 30 minutes before baking.
• Don’t overmix: Stir the dough only until ingredients are combined to keep cookies tender.
• Customize freely: Swap in your favorite mix-ins — dried cranberries, chopped dried fruit, crushed candy canes, or extra chocolate chips all work well.

Cooking Tips

• Use a cookie scoop: A scoop ensures evenly sized cookies and consistent baking.
• Watch baking time: Remove cookies when the edges are golden even if the centers look soft; cooling will finish the set.
• Invest in quality: Good butter and high-quality chocolate noticeably improve flavor.

Serving Suggestions

These cookies pair wonderfully with a cold glass of milk or a warm mug of hot chocolate. They’re also a festive addition to a holiday cookie platter alongside peppermint bark and gingerbread.
