From the moment I mix the melted butter with the sugars, I know I’m in for something special.

Ingredients You’ll Need

These ingredients are straightforward but essential, each one bringing something unique to the texture, taste, and festive look of the cookies. From the rich butter to the colorful M&Ms and sprinkles, every component is a little piece of holiday magic.

• ½ cup unsalted butter (melted): Adds a rich, creamy base that makes the bars wonderfully soft and flavorful.
• ½ cup packed light brown sugar: Brings a subtle molasses sweetness and moisture for chewy texture.
• ⅓ cup granulated sugar: Balances sweetness and helps create a slight crust on top for that perfect bite.
• 1 large egg (room temperature): Binds the ingredients together and adds structure to the bars.
• 1 teaspoon vanilla extract: Provides warm aroma and depth to all the flavors.
• 1 cup all-purpose flour: The base that holds everything together with its tender crumb.
• ¼ teaspoon salt: Enhances sweetness and balances all the flavors.
• ½ cup semi-sweet chocolate chips: Little pockets of melty chocolate that make every bite special.
• ½ cup red and green M&M’s: Festive colors and crunchy texture that scream holiday fun.
• ¼ cup Christmas jimmies: Adds an extra pop of color and sugary crunch inside the bars.
• Christmas sprinkles (for sprinkling over the baked cookie bars): Perfect finishing touch to make them look extra festive.

Directions

Step 1: Preheat your oven to 350°F. Lightly brush an 8×8-inch square baking pan with some of the melted butter, then line it with parchment paper leaving about a 2-inch overhang on two sides. This makes lifting the bars out super easy later.

Step 2: In a large bowl, whisk together the remaining melted butter, light brown sugar, and granulated sugar until the mixture is smooth and creamy. Then whisk in the egg and vanilla extract until the batter is fully combined.

Step 3: Add the flour and salt to the wet mixture. Gently mix them in just until everything is moistened—do not over-mix or the bars can become dense instead of tender.

Step 4: Carefully fold in half of the semi-sweet chocolate chips, about one-third of the M&M’s, and all the Christmas jimmies. This ensures color and flavor are distributed throughout the bars.

Step 5: Transfer the batter into the prepared pan. Use a rubber spatula to smooth out the top evenly, then sprinkle the remaining M&M’s over the surface for a festive look.

Step 6: Bake for about 20 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Be sure not to overbake to maintain that perfect soft texture.

Step 7: Remove the pan from the oven and place it on a wire rack. While still warm, sprinkle extra Christmas sprinkles over the top if you like a bit of extra sparkle. Let the bars cool completely in the pan. Once cooled, use the parchment overhang to lift them out and transfer to a cutting board. Cut into squares and enjoy!

Servings and Timing

This recipe yields about 9 generous servings, perfect for sharing with friends and family during holiday gatherings. The prep time takes roughly 10 minutes, and baking requires 20 minutes, so you’ll have these festive treats ready in just about 30 minutes total. Allow extra cooling time for the bars to set fully before slicing—about 15 to 20 minutes works wonderfully to keep them from crumbling.

How to Serve This Christmas Bar Cookies Recipe

I love serving these Christmas Bar Cookies slightly warmed because it brings out that melty chocolate goodness and makes the bars even more comforting. If I’m hosting a holiday party, I usually plate them on a festive platter with a sprinkle of extra colored jimmies around the edges to make it visually inviting. For a cozy night in, they’re best alongside a mug of hot cocoa or a creamy latte — the sweet, warm beverages complement the buttery sweetness perfectly.

For something a bit more grown-up, these cookies pair beautifully with a glass of rich, fruity red wine or a spiced holiday cocktail like mulled wine or eggnog. I also enjoy cutting them into bite-sized pieces and arranging them with other holiday desserts for a festive cookie tray. They’re ideal for dessert tables, office parties, or as a lovely homemade gift packed in pretty tins or wrapped in cellophane tied with a ribbon.

If you want to mix things up presentation-wise, I love topping bars with a small dollop of whipped cream and a few fresh cranberries or mint leaves for a pop of color and freshness, making them both festive and elegant for holiday dinners. No matter how you serve them, these bars bring warmth, joy, and festive spirit to your table.

Variations

I often experiment with this Christmas Bar Cookies Recipe to keep things exciting. If you prefer a nutty crunch, adding chopped pecans or walnuts works beautifully in place of some or all the chocolate chips. For a softer, more cake-like texture, I’ve swapped half the all-purpose flour for almond flour, which also adds a subtle nutty flavor that pairs nicely with the festive candies.

If you need a gluten-free option, I recommend using a 1-to-1 gluten-free baking flour blend and being careful not to over-mix to keep the bars tender. For a vegan twist, I usually replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and use dairy-free butter. It requires a slightly longer bake time but still turns out wonderfully delicious.

To play with flavors seasonally, I’ve added a teaspoon of ground cinnamon or ginger to the dry ingredients for a holiday spice vibe. Alternatively, substitute peppermint-flavored chips for chocolate chips to add a refreshing minty note. Baking these as mini bar cookies in a muffin tin also makes them perfect for individual portions — just reduce baking time by a few minutes.

Storage and Reheating

Storing Leftovers

I like to store any leftover Christmas Bar Cookies in an airtight container at room temperature to keep them soft and fresh. They usually last beautifully for up to 4-5 days, though in my house, they rarely stick around that long! To maintain the colorful topping’s vibrancy, I avoid stacking bars directly atop one another without parchment sheets in between.

Freezing

These bar cookies freeze wonderfully, which is a lifesaver during the bustling holidays. I typically cut them into squares first, then arrange them in a single layer on a baking sheet to freeze until firm. After that, I transfer the frozen bars to a freezer-safe airtight container or heavy-duty freezer bag. Properly frozen, they keep for up to 3 months. This way, you can prep batches ahead of time and thaw only what you need.

Reheating

When reheating, I prefer warming the bars gently in the microwave for about 10-15 seconds to revive that just-baked softness and melty chocolate. Avoid overheating, as that can dry them out. Alternatively, a quick 5-minute warm-up in a 300°F oven wrapped loosely in foil works well if you want a slight crisp on the edges. Either method brings back their fresh-from-the-oven charm beautifully.

FAQs

Can I use different candies instead of M&M’s?

Absolutely! I often swap in festive candy-coated chocolates, mini Reese’s Pieces, or even chopped candy canes for peppermint flavor. Just be sure to use candies that won’t melt excessively at baking temperature.

What if I don’t have Christmas jimmies — can I omit them?

Yes, the cookie bars will still taste amazing without the jimmies. They add texture and a bit of extra sparkle, but if you don’t have any, just omit or substitute with sprinkles or colored sugar you have on hand.

Can I double this recipe for a larger batch?

Definitely! I usually double everything and bake in a 9×13-inch pan, increasing the baking time by roughly 5-8 minutes. Just keep an eye on the bars near the end and do the toothpick test for doneness.

How do I prevent the bars from becoming dry?

The key is not over-mixing the batter and avoiding overbaking. Removing the bars as soon as a toothpick comes out clean keeps them soft and chewy. Storing in airtight containers also helps maintain moisture.

Can I make these ahead of time for a party?

Yes! These bars hold up well for a day or two at room temperature and can be made several days in advance and stored in the fridge. Just bring them to room temperature before serving for the best texture.

Conclusion

If you’re looking for a festive, delicious, and fuss-free treat, I wholeheartedly encourage you to try this Christmas Bar Cookies Recipe.
