What Ingredients You Will Need

This recipe uses simple, everyday ingredients with a festive twist thanks to the Christmas M&Ms. Here’s what you’ll need:

• Unsalted butter, softened: Adds richness and moisture to the cookie bars.
• Brown sugar: Provides the chewy texture and a hint of caramel flavor.
• Granulated sugar: Balances the sweetness and adds a slight crunch.
• Large eggs: Acts as a binder and gives the bars structure.
• Vanilla extract: Enhances the overall flavor.
• All-purpose flour: The main structure for the cookie bars.
• Baking soda: Helps the bars rise just enough to stay soft and chewy.
• Salt: Balances the sweetness and enhances the other flavors.
• Christmas M&Ms: The star of the show! Choose red and green M&Ms for the perfect holiday look.
• Chocolate chips: Optional, but adds extra gooey chocolate goodness.

If you’re missing an ingredient, don’t worry. You can make simple substitutions like using salted butter (just skip the added salt) or swapping out the Christmas M&Ms for any other candy-coated chocolate. Want a gluten-free version? Use a one-to-one gluten-free flour blend—it works beautifully!

Equipment Needed

You don’t need much to make these festive cookie bars. Here’s what you’ll need:

• Mixing bowls: One large bowl for the dough and a smaller one for dry ingredients.
• Electric mixer: A hand mixer or stand mixer works great to cream the butter and sugars.
• 9×13-inch baking pan: The ideal size for these bars. Line it with parchment paper for easy removal.
• Spatula: To spread the batter evenly in the pan.
• Measuring cups and spoons: For accurate measurements of your ingredients.

If you don’t have a 9×13-inch pan, you can use an 8×8-inch pan for thicker bars—just adjust the baking time slightly to ensure they’re cooked through.

Preparation Method

1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, letting it slightly overhang the sides for easy removal.
2. In a large mixing bowl, cream together 1 cup (230g) softened unsalted butter, 1 cup (200g) brown sugar, and ½ cup (100g) granulated sugar until light and fluffy. This should take about 2-3 minutes using an electric mixer.
3. Add 2 large eggs, one at a time, mixing well after each addition. Stir in 1 ½ teaspoons vanilla extract.
4. In a separate bowl, whisk together 2 ½ cups (315g) all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix, as this can make the bars tough.
6. Gently fold in 1 cup (180g) Christmas M&Ms and ½ cup (90g) chocolate chips (optional) using a spatula. Reserve a small handful of M&Ms for topping.
7. Spread the dough evenly into the prepared baking pan. Use the spatula to smooth out the top and press the reserved M&Ms on the surface for a festive look.
8. Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean. Don’t overbake—the bars should be slightly soft in the center for the perfect chewy texture.
9. Remove the pan from the oven and let the bars cool completely in the pan before lifting them out using the parchment paper. Slice into squares or rectangles and serve!

Cooking Tips & Techniques

These cooking tips will ensure your Chewy Christmas M&M Cookie Bars turn out perfectly:

• Don’t overmix: Once you’ve added the dry ingredients, mix just until combined. Overmixing can lead to dense and tough bars.
• Use room temperature eggs: This helps the ingredients mix more evenly and creates a smoother dough.
• Use parchment paper: Lining your baking pan with parchment paper not only prevents sticking but also makes it super easy to lift the bars out once they’re cool.
• Keep an eye on the bake time: Overbaking can make the bars dry. Aim for a slightly soft center—they’ll firm up as they cool.
• Reserve some M&Ms: Pressing a few M&Ms onto the top before baking ensures a festive look once they’re done.

Variations & Adaptations

Make this recipe your own with these fun variations:

• Gluten-Free: Substitute the all-purpose flour with a one-to-one gluten-free baking mix for perfectly chewy gluten-free bars.
• Nutty Delight: Add ½ cup of chopped pecans or walnuts for extra crunch and flavor.
• Seasonal Swaps: Change up the M&Ms for other seasonal candies like pastel-colored ones for Easter or orange and brown for Halloween.
• Dairy-Free: Use dairy-free butter and dairy-free chocolate chips for a treat everyone can enjoy.
• Extra Chocolate: Drizzle melted white chocolate over the cooled bars for an extra festive touch.

Serving & Storage Suggestions

These Chewy Christmas M&M Cookie Bars are best served:

• At room temperature: Let them cool completely before slicing for clean, even bars.
• With a glass of milk: Classic pairing for cookies and bars!
• On a holiday platter: Arrange them on a festive tray with other holiday treats for a show-stopping dessert table.

Storage Instructions: Store the bars in an airtight container at room temperature for up to 5 days. If you need to keep them longer, wrap them tightly in plastic wrap and store them in the freezer for up to 3 months. To reheat, simply let them thaw at room temperature or warm them slightly in the microwave for a gooey texture.
