- Large eggs (2): These create structure and moisture for a perfectly set cookie bar.
- Holiday-colored chocolate chips or M&Ms (1 cup): Bursting with festive color and pockets of chocolatey goodness.

How to Make Holiday Cake Mix Cookie Bars Recipe
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F (175°C), the perfect temperature for even baking. Then, line a 9×13-inch baking pan with parchment paper or apply a generous coating of grease. This ensures your cookie bars will come out easily and keep their lovely shape.
Step 2: Mix the Base Ingredients
In a large bowl, combine the cake mix, melted butter, and eggs. Stir until everything is fully incorporated into a thick dough. The beauty here is you’re starting with a box cake mix but transforming it into something entirely new and festive!
Step 3: Add the Festive Mix-Ins
Gently fold in the holiday-colored chocolate chips, optional white chocolate chips, and sprinkles. These little pops of color and sweetness will be spread throughout each bite, turning ordinary bars into a holiday celebration of flavor.
Step 4: Press the Dough Into the Pan
Transfer the dough to your prepared pan and use a spatula or your hands to spread it evenly across, pressing it down firmly so the bars hold together after baking. This step will ensure uniform thickness for an even bake.
Step 5: Bake Until Golden
Bake in your preheated oven for about 20 to 25 minutes. You’ll want to bake just until the edges are golden and the center is fully set but still soft. Avoid overbaking to keep the bars from drying out.
Step 6: Cool Completely and Slice
Allow the cookie bars to cool fully in the pan. This cooling time is key because it helps the bars firm up and makes cutting them into neat pieces much easier. Then slice into 20 squares and enjoy!
How to Serve Holiday Cake Mix Cookie Bars Recipe

Garnishes
These cookie bars are delightful on their own, but you can elevate the presentation by sprinkling a few extra holiday sprinkles on top just before serving or drizzle with a bit of melted white or dark chocolate for an elegant touch that still keeps the festive spirit.
Side Dishes
Pair these bars with a glass of cold milk, a rich cup of hot cocoa, or even a festive coffee latte. The creamy drinks complement the buttery, chocolatey flavors in the bars perfectly and make for a cozy holiday treat.
Creative Ways to Present
For holiday parties, arrange the cookie bars on a beautiful serving platter garnished with fresh holly leaves or candy canes for extra cheer. You can also individually wrap bars in cellophane tied with colorful ribbons to give as charming homemade gifts that everyone will appreciate.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the cookie bars in an airtight container at room temperature. They’ll stay moist and flavorful for up to 3 days, making them perfect for prepping ahead of a party or sweetening up your workweek snacks.
Freezing
These bars freeze wonderfully! Wrap them tightly in plastic wrap, then place in a freezer-safe container or bag. They keep well in the freezer for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator for best results.
Reheating
To bring out that fresh-baked warmth, pop a bar in the microwave for about 10-15 seconds or heat in a low oven for a few minutes. The slight warmth makes the chocolate melty and the texture even more irresistible.
