Easy M&M Christmas Cookie Bars - a perfect holiday treat recipe

It had been quite some time since I last whipped up a delightful bar recipe. Lately, my baking endeavors had been heavily focused on individual cookies, and the comforting simplicity of bar cookies had unfortunately taken a back seat. However, sometimes the best inspiration comes from the past.

While browsing through my grandma’s treasured old cookbook, I stumbled upon a remarkably straightforward recipe for classic cookie bars. The moment I saw it required only four ingredients, I was completely captivated. This discovery felt like a revelation, perfectly aligning with my desire for uncomplicated, yet utterly satisfying, holiday baking.

Grandma was truly a master of incredibly easy recipes, and I believe that’s where I inherited my passion for streamlining the baking process. Her philosophy was always about paring things down to their delicious essence, making recipes as simple and accessible as possible without sacrificing flavor. Fortunately, I inherited all her precious handwritten notes, which continue to be a source of endless inspiration, allowing me to carry on her legacy of effortless and delicious baking, especially during the festive season.

These particular cookie bars are incredibly simple to make, yet they deliver a huge punch of flavor and festive cheer, generously studded with those beautiful red and green M&M’s. Their vibrant appearance and delightful taste truly make me smile from ear to ear; I simply can’t get enough of them! Beyond personal enjoyment, they also make fantastic treats for all your upcoming holiday gatherings and parties. Given how ridiculously easy they are to prepare, you absolutely can’t go wrong by adding these to your holiday baking plans.

Frequently Asked Questions About M&M Christmas Cookie Bars

Should I use salted or unsalted butter for these cookie bars?

When it comes to butter, I often use whatever I have readily available in my fridge. However, if you’re mindful of your sodium intake, unsalted butter is generally the preferred choice for these cookie bars. Grandma’s original recipe called for unsalted butter, but I’ve personally tried them with salted butter and found them equally delicious. The slight saltiness can even enhance the sweetness of the M&M’s, so feel free to experiment based on your preference!

What is the best way to store leftover M&M cookie bars to keep them fresh?

Storing these cookie bars is incredibly simple, ensuring they remain soft and chewy for days. You can either place individual bars in a large airtight container at room temperature, or for an even easier option, simply cover the entire baking pan tightly with foil and leave it on your kitchen counter. A large plastic bowl with a secure lid or a zip-top bag also works wonderfully to keep them fresh and delicious. For longer storage, consider freezing them.

How to make M&M Christmas Cookie Bars - step-by-step guide

How many servings does this M&M Christmas Cookie Bar recipe yield?

Typically, this recipe yields between 9 to 12 cookie bars, depending on how you choose to slice them. I find that making two lengthwise cuts creates three neat rows, and then either three cuts across (for 12 bars) or two cuts across (for 9 bars) works perfectly. The beauty of bar cookies is their versatility; you can easily adjust the size to suit your needs, whether you prefer larger individual servings or smaller bites for a party platter.

Can this M&M Christmas Cookie Bar recipe be doubled for a larger batch?

Yes, absolutely! This recipe can certainly be doubled if you need a larger quantity for a big gathering or simply want more to enjoy. However, it’s important to bake the doubled dough in two separate baking pans. I do not recommend trying to bake a double batch of dough in one larger pan, as it can significantly affect baking time and the evenness of the cook, potentially resulting in undercooked centers or overbaked edges. Using two pans ensures optimal results.

Can I substitute other cake mix flavors in these cookie bars?

Yes, absolutely! While vanilla cake mix provides a classic and versatile base, these M&M cookie bars are incredibly adaptable. They are also fantastic with yellow or white cake mix, which will provide a similar soft and tender texture. You could even get adventurous with a chocolate cake mix for a double chocolate M&M bar, or a funfetti cake mix for an extra festive look, making them suitable for any occasion beyond Christmas!

How to Make M&M Christmas Cookie Bars: A Simple Step-by-Step Guide

  1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
  2. Lightly grease a 9×9 inch baking pan, then line it with parchment paper, ensuring the paper hangs over two opposite sides. This creates convenient handles for easy removal of the baked bars later.
  3. In a large mixing bowl, combine the cake mix, eggs, and melted butter. Mix these ingredients thoroughly until they are well combined and form a thick, cohesive dough.
  4. Gently fold in the holiday M&M’s. Be careful not to overmix, just enough to distribute the candies evenly throughout the dough.
  5. Transfer the dough into your prepared 9×9 inch pan. Using your hands or a spatula, press the dough evenly into the pan, forming a uniform layer.
  6. Bake for 25 to 35 minutes, or until the top of the bars achieves a beautiful golden brown color. To check for doneness, insert a toothpick into the center; it should come out mostly clean.
  7. Immediately after removing the bars from the oven, while they are still warm and soft, press additional M&M’s onto the tops. This adds extra visual appeal and a burst of chocolatey goodness.
  8. Allow the cookie bars to cool completely to room temperature within the pan before attempting to remove or cut them. This step is crucial for the bars to set properly and prevent crumbling.
  9. Once cooled, use the overhanging parchment paper to lift the entire slab of cookie bars out of the pan. Place them on a cutting board and slice into your desired size and shape.

Do I need to chill the dough for these M&M Christmas Cookie Bars?

One of the absolute best features of this M&M Christmas Cookie Bar recipe is that there’s no need for chilling the dough! This eliminates a significant waiting period often associated with cookie recipes, making these bars perfect for spontaneous baking. You can enjoy these delicious treats soon after a craving strikes, or quickly whip them up at the last minute when you realize you need a festive dessert for an unexpected gathering. It’s truly a time-saver during the busy holiday season, allowing you to go from craving to confection in record time.
