- Yellow or vanilla cake mix: The base that provides that soft, cakey texture and subtle sweetness.

- Large eggs: Helps bind everything together while giving structure to the bars.

How to Make Holiday Cake Mix Cookie Bars Recipe
Step 1: Preheat and Prepare Your Pan
Start by heating your oven to 350°F (175°C). Prepare a 9×13-inch baking pan by lining it with parchment paper or greasing it well to ensure your bars don’t stick and come out perfectly shaped.
Step 2: Mix the Base Ingredients
In a large bowl, combine the yellow or vanilla cake mix with the melted butter and eggs. Stir until everything is just blended together—the dough will be wonderfully thick, making it easy to handle.
Step 3: Fold in the Festive Mix-Ins
Gently fold in the holiday-colored chocolate chips, white chocolate chips if you’re using them, and the holiday sprinkles. This step is where your bars turn from simple to spectacular with bursts of color and pockets of flavor.
Step 4: Press the Dough into the Pan
Evenly spread and press the cookie dough into your prepared pan. Don’t be shy about pressing firmly so the bars hold together beautifully once baked.
Step 5: Bake Until Golden and Set
Bake the bars for 20 to 25 minutes. Keep an eye on the edges—they should turn a lovely golden brown, and the center should be set but still soft to the touch.
Step 6: Cool and Cut into Bars
Allow the bars to cool completely in the pan. This helps them firm up and makes for cleaner, prettier cuts when you slice them into generous portions for serving.

Garnishes
For added flair, consider a light dusting of powdered sugar or a drizzle of melted white chocolate. These little touches can make your Holiday Cake Mix Cookie Bars Recipe feel even more festive and elegant.
Side Dishes
These cookie bars pair wonderfully with a warm cup of hot cocoa, a glass of cold milk, or even a festive eggnog. Their sweet, colorful nature also complements simple fresh fruit or a scoop of vanilla ice cream for a delightful dessert experience.
Creative Ways to Present
Cut your bars into fun shapes using cookie cutters for a party, or stack them on a pretty platter surrounded by holiday greenery and ornaments. Wrapping individual bars in cellophane with a ribbon makes for adorable edible gifts everyone will adore.
Make Ahead and Storage
Storing Leftovers
You can keep leftover bars fresh by storing them in an airtight container at room temperature for up to five days. This makes them a great make-ahead snack or dessert to enjoy throughout the week.
Freezing
If you want to save your Holiday Cake Mix Cookie Bars Recipe for later, wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag. They freeze well for up to three months, letting you enjoy their festive goodness any time.
Reheating
To enjoy your bars warm, simply let them thaw at room temperature if frozen, then heat briefly in the microwave for about 15-20 seconds. This brings back that soft, melty texture like they’re freshly baked.
FAQs
Can I use a different cake mix flavor?
Absolutely! While yellow or vanilla is classic, feel free to experiment with funfetti, spice, or even chocolate cake mix to tailor the bars to your holiday mood.
What if I don’t have holiday-colored chocolate chips?
No worries! You can substitute regular chocolate chips or any candy-coated chocolates you have on hand. The flavor is what truly counts, and the festive look is a bonus.
Can I make these bars gluten-free?
Yes, if you use a gluten-free cake mix, this recipe becomes gluten-free as well. Just double-check all your additional mix-ins to ensure they’re gluten-free.
How thick should the bars be before baking?
Press the dough so it is evenly spread in the 9×13-inch pan, usually about 1 inch thick. This thickness ensures they bake through but stay soft and chewy.
Can I add nuts or other mix-ins?
Definitely! Chopped nuts, dried fruits, or even shredded coconut make excellent additions and add texture and flavor contrast to these cookie bars.
