Step-by-Step Guide to Making Festive M&M’s Cookie Bars

Making these cake mix cookie bars is surprisingly straightforward, perfect for even novice bakers. Follow these simple steps to create a batch of irresistible holiday treats:

Step 1: Prepare Your Eggs. Begin by cracking two large eggs into a spacious mixing bowl. Using a whisk or a fork, beat them thoroughly until the yolks and whites are fully combined and slightly frothy. This ensures they incorporate smoothly into the batter, giving your cookie bars a consistent texture.

Step 2: Combine Wet and Dry Ingredients. To the bowl with your whisked eggs, add the entire box of white cake mix and the melted salted butter. It’s important to melt the butter completely to ensure it disperses evenly throughout the thick batter. Using electric mixers, beat these ingredients together until just combined. The batter will be quite thick, almost like a very firm cookie dough. Avoid overmixing, as this can lead to tougher cookie bars.

Step 3: Fold in the Festive Mix-ins. Now for the fun part! Gently fold 1 cup of the holiday-colored M&M’S and all the white chocolate chips into your thick batter. This step is often easiest to do by hand with a sturdy rubber spatula, as the batter will be very dense. Mix until the M&M’s and white chocolate chips are evenly distributed throughout the dough, ensuring every bite will be full of holiday flavor.

Step 4: Prepare for Baking. Take a 9×13 inch baking dish and lightly grease it with cooking spray. This will prevent the bars from sticking and make removal much easier. Once greased, carefully transfer the thick cookie bar batter into the dish. Spreading this thick batter can be a little challenging, but a few tricks will help.

Step 5: Garnish and Bake. Once the batter is spread evenly in the dish, sprinkle the remaining red and green M&M’S generously over the top. This not only adds extra flavor and texture but also creates a beautiful, festive visual appeal. Bake the cookie bars in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the edges are lightly golden brown and a toothpick inserted into the center comes out clean. Be vigilant not to overbake, as this can lead to dry, crumbly bars instead of the desired soft and chewy texture.

Step 6: Cool and Serve. Once your delightful Christmas cookie bars are baked to perfection, remove them from the oven. This next step is crucial for perfect bars: allow them to cool completely in the baking dish before attempting to cut them. Cooling allows the bars to set and firm up, making them much easier to slice into neat, perfect pieces. Patience is a virtue here!

Once cooled, slice them into squares, triangles, or festive shapes, and watch them disappear as your family and friends enjoy every sweet, colorful bite!

Every bite of these delightful cookie bars is a symphony of sweet white chocolate and crunchy M&M’s. The chewy texture paired with the bursts of chocolatey goodness makes them utterly addictive and a true crowd-pleaser.
