Ingredients You’ll Need

Getting started with this Cake Mix Cookie Bars with Chocolate Chips and Holiday M&M’s Recipe is a breeze because it relies on a short list of ingredients that you probably have in your pantry already. Each component plays a special role to create a moist, chewy, and festive bar that’s bursting with color and flavor.

Yellow cake mix: This forms the base with a tender crumb and subtle sweetness that’s perfect for cookie bars.
Instant vanilla pudding mix: Adds richness and moisture, keeping the bars soft and chewy long after baking.
Water: Helps bind the dry ingredients and activates the batter for baking.
Vegetable oil: Provides fat for richness and a moist texture without heaviness.
Large eggs: Act as a binder and add structure while contributing to the bars’ tender crumb.
Milk chocolate chips: For decadent pockets of melt-in-your-mouth chocolate throughout the bars.
Holiday M&M’s: These bring cheerful bursts of color and crispy texture that make this treat perfect for seasonal celebrations.

How to Make Cake Mix Cookie Bars with Chocolate Chips and Holiday M&M’s Recipe

Step 1: Prepare Your Oven and Pan

Preheat your oven to 350 degrees Fahrenheit to ensure it’s at the perfect temperature when your batter is ready. Grease a 9×13 inch baking dish with cooking spray to keep your bars from sticking so they come out in perfect squares every time.

Step 2: Mix the Batter

In a large mixing bowl, combine the yellow cake mix and instant vanilla pudding mix for that wonderful blend of sweetness and moisture. Add in the water, vegetable oil, and eggs, then stir everything together until you have a thick, consistent batter. Don’t be alarmed by the thickness — it’s what gives these bars their amazing chewy texture. Finally, fold in the milk chocolate chips and holiday M&M’s for tasty pockets of chocolate and festive pops of color.

Step 3: Bake to Perfection

Spread your batter evenly into the prepared baking dish so every piece is just as delightful. Pop it into the oven and bake for 24 to 26 minutes, or until the edges are gently golden and the middle is set but still soft. Once done, carefully remove from the oven and allow the bars to cool completely before slicing—this step helps them hold together and lets the flavors meld.

How to Serve Cake Mix Cookie Bars with Chocolate Chips and Holiday M&M’s Recipe

Garnishes

While these bars are fantastic as they are, a light dusting of powdered sugar or a drizzle of melted white chocolate can elevate their festive appeal. A few extra holiday M&M’s on top right after baking add a fun, decorative touch that tempts all ages.

Side Dishes

Pair these chewy, sweet bars with a scoop of vanilla ice cream or a dollop of freshly whipped cream for a comforting dessert experience. For holiday gatherings, a hot cup of cocoa or spiced coffee complements the chocolate and M&M flavors beautifully.

Creative Ways to Present

Consider cutting the bars into bite-sized squares for an easy party platter, or stack them with wax paper in between layers inside a decorative tin to give as charming homemade gifts. Wrapping individual bars in cellophane with a festive ribbon makes for delightful grab-and-go treats at any celebration.

Make Ahead and Storage

Storing Leftovers

These cookie bars keep wonderfully in an airtight container at room temperature for up to 4 days, staying soft and moist. If your kitchen is warm, you might refrigerate them to keep the chocolate chips nice and firm.

Freezing

Want to prepare ahead? Wrap the bars tightly in plastic wrap and aluminum foil, then freeze them for up to 3 months. Thaw at room temperature when ready to enjoy, and they will taste just as fresh and delicious.

Reheating

If you prefer your bars a bit warm, pop a slice into the microwave for about 10 to 15 seconds, just enough to melt the chocolate chips slightly and bring back that freshly baked feel.

FAQs

Can I use a different cake mix flavor?

Absolutely! While yellow cake mix is classic here, you could try chocolate or spice cake mix for a fun twist that complements the chocolate chips and M&M’s brilliantly.

What if I don’t have holiday M&M’s?

No worries! Regular M&M’s or even other festive candies, like mini peanut butter cups or candy cane bits, can work just as well and add your own flair to the bars.

Is this recipe gluten-free?

The traditional cake mix used here contains gluten, but you could experiment with a gluten-free yellow cake mix and pudding mix to make a gluten-free version that’s just as tasty.

Can I make these bars dairy-free?

To make these bars dairy-free, try substituting the milk chocolate chips and pudding mix with dairy-free alternatives, and ensure your cake mix is free from dairy ingredients as well.

How thick should the batter be?

The batter will be quite thick—this is normal! It helps create that chewy, cookie-like texture once baked, so resist the urge to thin it out with extra liquid.
