What Are Kitchen Sink Cookies?
Kitchen sink cookies are best described as “loaded” cookies filled with a mix of sweet, salty, crunchy, and chewy ingredients. The name comes from the idea that you can add anything you want—everything but the kitchen sink! Traditionally, they include chocolate chips, pretzels, toffee bits, potato chips, and various candies. For the Christmas version, we add seasonal colors and flavors like red and green M&M’s and festive sprinkles. The result is a cookie packed with texture, flavor, and holiday cheer—loved by both kids and adults.

The Essential Ingredients
The mix-ins are what make Christmas Kitchen Sink Cookies so unique. Here are the most common additions:
Red & Green M&M's
These chocolate candies give the cookies their signature festive look. You can use classic milk chocolate or holiday mint versions for extra flavor.
White Chocolate Chips
White chocolate adds creamy sweetness that balances the salty elements. You can replace them with semi-sweet or dark chocolate chips if you prefer.
Pretzels
Chopped pretzels create the perfect sweet-and-salty contrast while adding a satisfying crunch.
Festive Sprinkles
Choose red and green sprinkles or jimmies. They enhance the appearance without changing the flavor.
Optional Add-Ins
- Toffee bits
- Crushed potato chips
- Mini marshmallows
- Chopped nuts
- Caramel bits
- Peanut butter chips
Mix and match depending on your personal taste.
Tips for Perfect Cookies
Chill the Dough
Chilling is optional but highly recommended. It helps maintain the cookie shape, prevents spreading, and enhances flavor.
Avoid Overmixing
Once flour is added, mix gently. Overmixing can make the cookies tough instead of soft and chewy.
Add Mix-Ins Gently
Fold them in at the end so pretzels don’t break and chocolate chips don’t melt. Press a few extra mix-ins on top before baking for a bakery-style look.
Observe the Bake Time
Kitchen sink cookies are best when slightly underbaked. They will finish setting as they cool.
