Introduction
Christmas M&M Cookie Bars are festive, soft, chewy bars loaded with chocolate chips and colorful holiday candies. These dessert bars combine a classic cookie-like texture with vibrant red, green, and white candy pieces — perfect for holiday dessert trays, gift boxes, parties, or cozy family baking.
Why These Bars Are So Loved
These cookie bars take all the best parts of a traditional chocolate chip cookie and turn it into a shareable, easy-to-slice dessert. The combination of rich cookie dough, melty chocolate chips, and cheerful holiday candies makes every square delightful. They require no scooping — just press the dough into a pan, bake, and slice.
Ingredients You’ll Need
For the Dough
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 ¾ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
For the Mix-Ins
- 1 cup semi-sweet chocolate chips
- 1–1½ cups holiday-colored candy pieces (e.g., red, green & white candy bits)
The Art of Making Cookie Bars
The success of these bars lies in a well-balanced dough that’s moist, chewy, and holds plenty of mix-ins. Using both brown and granulated sugar gives the bars depth of flavor and a tender texture, while spreading the dough evenly ensures every bite gets a festive mix of candy and chocolate.
Step-by-Step Instructions
1. Preheat & Prepare Pan
Preheat your oven to 350°F (175°C).
Grease a square baking pan (8×8 or 9×9 inches) or line it with parchment paper for easy removal.
2. Cream Butter & Sugars
In a large bowl, beat softened butter, granulated sugar, and brown sugar until smooth and creamy.
3. Add Eggs & Vanilla
Beat in the eggs one at a time.
Add vanilla extract and mix until combined.
4. Combine Dry Ingredients
In a separate bowl, whisk together flour, baking soda, and salt.
Gradually add the dry mixture to the wet ingredients, mixing until just combined.
5. Add Chocolate & Candy
Fold in chocolate chips and holiday-colored candy pieces, distributing them evenly throughout the dough.
6. Spread Dough in Pan
Spread the cookie dough evenly into the prepared baking pan.
Press lightly if needed to level the top.
7. Bake
Bake for 25–30 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay).
8. Cool & Slice
Allow the cookie bars to cool completely in the pan — about 15–20 minutes — so they set before slicing.
Slice into squares or rectangles and serve.
Tips for Best Results
- Use softened butter (not melted) for the best texture.
- Don’t overmix once the flour is added — this keeps the bars tender.
- Press a few extra candies on top before baking for a festive look.
- Cool completely for cleaner slices and easier serving.
Creative Variations
- Peppermint Crunch: add crushed peppermint candies along with the holiday chocolates.
- White Chocolate Twist: use white chocolate chips or chunks for extra sweetness.
- Nutty Boost: stir in chopped pecans or walnuts for texture.
- Sprinkle Fun: add colorful sprinkles for extra festive flair.
- Caramel Drizzle: once baked and cooled, drizzle caramel sauce over the top for a sweet finish.
Storage & Freshness
Store cooled bars in an airtight container at room temperature for up to 4–5 days.
Layer with parchment paper to prevent sticking.
Bars can also be frozen for up to 2 months — thaw before serving.
Conclusion
Christmas M&M Cookie Bars are festive, colorful, and packed with sweet, chewy goodness — perfect for the holidays or any celebration. With simple ingredients and straightforward steps, they deliver big flavor and fun in every bite.
