Ingredients You’ll Need

Here’s everything you need to make the best Christmas Kitchen Sink Cookies that are chewy, golden, and full of holiday goodness.

Dry Ingredients

• 2 ¼ cups all-purpose flour
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ½ teaspoon salt

Wet Ingredients

• 1 cup (2 sticks) unsalted butter, softened
• ¾ cup brown sugar, packed
• ½ cup granulated sugar
• 2 large eggs
• 2 teaspoons pure vanilla extract

Add-Ins (The Fun Part!)

• ¾ cup semi-sweet chocolate chips
• ½ cup red and green M&M candies
• ½ cup crushed pretzels
• ¼ cup toffee bits (optional but highly recommended)
• ¼ cup white chocolate chips or butterscotch chips
• Flaky sea salt for sprinkling (optional)

How to Make Christmas Kitchen Sink Cookies in 5 Easy Steps

Step 1: Prep the Basics

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

Step 2: Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until light and creamy — about 2–3 minutes.

Step 3: Add the Eggs and Vanilla

Mix in the eggs one at a time, followed by the vanilla extract. Beat until fully combined.

Step 4: Mix the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Slowly add the dry mixture to the wet ingredients, mixing until just combined — don’t overmix.

Step 5: Fold in the Goodies

Stir in the chocolate chips, M&Ms, pretzels, toffee bits, and white chocolate chips. The dough should be thick and full of chunky mix-ins.

Scoop the dough into 2-tablespoon-sized balls and place them about 2 inches apart on your prepared baking sheet. Press a few extra M&Ms or pretzel bits on top for that festive bakery-style look.

Bake for 10–12 minutes, or until the edges are golden but the centers still look slightly soft. Sprinkle with sea salt right out of the oven, if desired.

Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.

Common Mistakes to Avoid

1. Overbaking
The cookies should look slightly underbaked when you pull them out — they’ll set as they cool. Overbaking makes them hard instead of chewy.

2. Skipping the Chill Step (if your dough feels too soft)
If your kitchen is warm or your dough is sticky, chill it for 20–30 minutes to prevent the cookies from spreading too much.

3. Overmixing the Dough
Mixing too long after adding the flour can make your cookies tough. Stop as soon as the flour is incorporated.

4. Using Too Many Add-Ins
It’s tempting to add everything, but too many mix-ins can make the dough fall apart. Stick to about 2–2 ½ cups total mix-ins.

5. Not Lining the Baking Sheet
Always use parchment paper or silicone mats — it helps the cookies bake evenly and prevents sticking.

Fun Variations to Try

1. Peppermint Twist

2. White Chocolate Cranberry

3. Peanut Butter Lovers
Add peanut butter chips and chopped peanuts for a sweet-salty combo.

4. Caramel Pretzel Crunch
Mix in caramel bits and extra pretzel pieces for more crunch and gooey goodness.

5. Gluten-Free Version
Use a 1:1 gluten-free baking flour and gluten-free pretzels for a celiac-friendly treat.
