Ingredients Section
To create these mouth-watering Christmas Cookie Bars, you’ll need the following ingredients:
- ¾ cup unsalted butter (softened, 1½ sticks): Room temperature butter works best for achieving that fluffy texture.
- 2 teaspoons vanilla extract: Always opt for pure vanilla for a richer flavor.
- 2/3 cup granulated sugar: This will add sweetness and balance to the rich brown sugar.
- 2 large eggs: Make sure they’re at room temperature for better incorporation into the batter.
- 3 cups all-purpose flour: Feel free to use a gluten-free blend if necessary.
- 1 teaspoon salt: Enhances the overall flavor, counteracting the sweetness.
- 1 cup packed brown sugar: The key to that chewy, caramel-like texture.
- 1 cup semi-sweet chocolate chips: Go for high-quality chocolate for the best flavor.
- 1 teaspoon baking soda: Ensures the bars rise perfectly.
- 1 cup Christmas M&M’s (divided, ½ cup for the dough, ½ cup for topping): Choose festive colors for visual appeal!
- ¼ cup white chocolate chips (for topping): Adds a beautiful contrasting look and flavor.
Quality & Substitutions:
- Butter: Always use unsalted butter for better control over the saltiness.
- Flour: If you’d like to lighten it up, consider substituting part of the flour with whole wheat flour.
- M&M’s: You could also use holiday-themed chocolate candies or sprinkles for variety.
Step-by-Step Instructions
Preheat the Oven: Preheat your oven to 325°F (165°C). Prepare a 9×13-inch baking pan by lightly greasing it or lining it with parchment paper for easy removal.
Cream the Butter and Sugars: In a large mixing bowl, cream the softened butter with both the brown sugar and granulated sugar using an electric mixer on medium speed for about 3 minutes until the mixture is light and fluffy.
Chef’s Tip: Make sure your butter is truly softened for the best consistency.
Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Mix until everything is fully blended and smooth, scraping the bowl as necessary.
Incorporate Baking Ingredients: Stir in the baking soda and salt, mixing gently. Gradually add the flour into the mixture, stirring until a soft dough forms. Avoid overmixing to maintain the tender texture of the bars.
Fold in the Goodies: Gently fold in 1 cup of semi-sweet chocolate chips and ½ cup of the Christmas M&M’s until evenly distributed.
Spread and Top: Spread the dough evenly into the prepared pan, using a spatula to smooth the surface. Sprinkle the remaining ½ cup of M&M’s and the white chocolate chips over the top.
Bake: Place the pan in the preheated oven and bake for 26-30 minutes. The bars are done when the edges are lightly golden brown and a toothpick inserted in the center comes out mostly clean.
Cool and Serve: Once baked, remove the pan from the oven and allow the cookie bars to cool completely in the pan. Once cooled, slice into squares and serve.
Chef’s Tip: For clean cuts, use a sharp knife and make sure the bars are completely cooled before slicing!

Expert Tips & Tricks
Storage: Store your cookie bars in an airtight container at room temperature for up to a week. For longer freshness, they can be kept in the fridge for up to two weeks or frozen for up to three months.
Make-Ahead Instructions: You can prepare the dough a day in advance. Just wrap it tightly in plastic wrap and refrigerate. When you’re ready, spread it in the pan and bake.
Troubleshooting: If your bars are too crumbly, it may be due to over-mixing. If they’re too soft, they might not have baked long enough. Trust your visual cues!
Serving Suggestions
Serve these delicious cookie bars with a side of cold milk or a warm cup of hot cocoa, perfect for dipping! If you’re feeling festive, top off each bar with a dollop of whipped cream or a scoop of vanilla ice cream. These cookie bars are ideal for holiday parties, cozy gatherings, or simply as a treat to share with loved ones during the hustle and bustle of the season.
Variations & Substitutions
Flavors: Try adding a splash of peppermint extract for a minty twist or replace the chocolate chips with caramel chunks for a different flavor profile.
Dietary Restrictions: For gluten-free bars, swap in a 1:1 gluten-free flour blend. To make them dairy-free, try coconut oil and dairy-free chocolate chips.
Seasonal Variations: During Halloween, swap the M&M’s for orange and black candies; in spring, pastel-colored candies can bring a cheerful vibe to your baking.
