Easy Holiday Blondie Bars: Your Go-To Festive Dessert
There’s something truly magical about homemade treats during the holidays. They bring warmth, cheer, and a touch of nostalgic comfort to any gathering. While the idea of baking from scratch can sometimes feel daunting amidst the hustle and bustle of the season, these Easy Holiday Blondie Bars offer a delightful shortcut without compromising on flavor or festive appeal. If you’re looking for a dessert that’s quick to prepare, impressive to serve, and irresistibly delicious, you’ve found your perfect match.
Over the years, our kitchen has seen a fair share of blondie recipes, each with its unique charm. From sophisticated homemade versions to incredibly simple cake mix-based delights, blondies consistently rank high on our list of favorite desserts. We’ve explored rich maple butter sauces and apple-infused variations, proving just how versatile these chewy, golden bars can be. So, it was only natural to create a blondie recipe that truly encapsulates the spirit of the holidays—bright, cheerful, and utterly delightful. This recipe takes our beloved cake mix blondie base and elevates it with seasonal flavors and festive decorations, making it an instant classic for your holiday dessert table.

The Undeniable Charm of Cake Mix Baking
The secret to the incredible ease and consistent deliciousness of these Holiday Blondie Bars lies in a simple yet brilliant ingredient: boxed cake mix. For many home bakers, a cake mix is a superhero in disguise, offering a reliable foundation that shaves off significant prep time without sacrificing quality. It provides a perfect blend of flour, sugar, leavening agents, and sometimes even a hint of flavor, ensuring a tender and moist crumb every time.
For this particular recipe, we’ve refined our favorite cake mix blondie technique. A slight adjustment involves layering the white chocolate chips between two portions of batter, a method we found yields a more even distribution and a delightful surprise in every bite. This layering technique helps prevent the chocolate chips from sinking entirely to the bottom, ensuring that rich pockets of melted white chocolate are dispersed throughout the blondies. Furthermore, we’ve introduced a touch of eggnog into the batter, which infuses the blondies with a distinct, creamy holiday flavor that is simply irresistible. If eggnog isn’t your preference or readily available, fear not – milk makes an excellent and equally delicious substitute, maintaining the desired consistency and moisture. The beauty of using a cake mix is its adaptability, allowing you to create impressive desserts with minimal effort, making your holiday baking stress-free and enjoyable.
One of the most appealing aspects of this blondie recipe is its remarkable versatility. While we love the classic combination of yellow cake mix and white chocolate chips for a festive look, you are entirely free to explore and customize! Imagine using a spice cake mix for a warmer flavor profile, or perhaps a chocolate cake mix for a richer, more intense blondie (or rather, brownie-like) experience. The type of chocolate chips can also be swapped—milk chocolate, dark chocolate, or even butterscotch chips could create a whole new flavor sensation. And, of course, the vibrant, festive sprinkles are non-negotiable! They add that essential celebratory touch, instantly transforming a simple baked good into a holiday masterpiece that’s as beautiful to look at as it is delicious to eat. This recipe isn’t just about baking; it’s about celebrating the joy of customization and making treats truly your own.

Essential Ingredients for Festive Blondies
Gathering your ingredients for these Holiday Blondie Bars is incredibly straightforward, highlighting the simplicity of this recipe. Each component plays a vital role in creating the perfect balance of flavor, texture, and festive cheer.
Ingredients Needed:
- Yellow Cake Mix: The cornerstone of our recipe, providing a sweet, vanilla-flavored base that’s consistently moist and tender. A standard 15.25-ounce box is perfect.
- Large Egg: Acts as a binder, helping to hold the blondies together and contribute to their rich, chewy texture.
- Salted Butter: Adds a crucial depth of flavor and moisture. Using salted butter helps to balance the sweetness of the cake mix and chocolate chips, creating a more complex taste profile. One stick (1/2 cup) is all you need.
- Eggnog (or Milk): This is where the holiday magic truly comes in! Eggnog infuses the blondies with its signature creamy, spiced flavor. If you prefer a simpler taste or don’t have eggnog, regular milk works perfectly as a substitute, ensuring a moist batter.
- White Chocolate Chips: These melt into delightful pockets throughout the blondies, adding a creamy sweetness and a visually appealing contrast, especially when paired with colorful sprinkles.
- Festive Sprinkles: Essential for that joyous holiday look! Choose red, green, and white sprinkles, or any mix that brings a smile to your face. They are not just for decoration but also add a fun texture.
This concise list of ingredients means you likely have most of what you need already in your pantry, making spontaneous holiday baking sessions a delightful possibility. The quality of each ingredient contributes to the final outcome, so choose your favorites and get ready to create something wonderful.

Crafting Your Holiday Blondies: A Simple Step-by-Step Guide
Making these Easy Holiday Blondie Bars is as enjoyable as eating them. The process is straightforward, requiring minimal fuss and delivering maximum deliciousness. Follow these simple steps to bring your festive treats to life:
How to Make Holiday Blondies:
- Prepare the Batter: In a large mixing bowl, combine the yellow cake mix, large egg, melted salted butter, and eggnog (or milk). Using a hand blender or an electric mixer, blend these ingredients until they are thoroughly combined and the batter is smooth. Be careful not to overmix; just combine until no dry streaks of cake mix remain. Once the base batter is ready, gently fold in a generous amount of your festive sprinkles. This ensures a distribution of colorful flecks throughout your blondies.
- Layer the Batter and Chocolate Chips: Prepare an 11 x 7-inch baking pan by spraying it generously with nonstick cooking spray. This will ensure your blondies release easily after baking. Evenly spread exactly half of the prepared batter into the bottom of the pan. This creates your first layer. Then, sprinkle a generous layer of white chocolate chips over this batter. The remaining batter is then carefully spread over the white chocolate chips, creating a delicious middle layer. This layering technique is key to ensuring that every square of blondie has a delightful surprise of melted white chocolate.
- Add More Sprinkles: For an extra pop of holiday cheer and a beautiful finish, sprinkle some more festive sprinkles evenly over the top layer of batter. This final touch makes the blondies visually stunning and even more appealing.
- Bake to Golden Perfection: Preheat your oven to 350°F (175°C). Place the baking pan into the preheated oven and bake for approximately 25 minutes. Keep an eye on your blondies; they are done when the edges are a beautiful golden color and a toothpick inserted into the center comes out with moist crumbs, not wet batter. Avoid overbaking, as this can lead to dry blondies; we want them soft and chewy!
- Cool and Cut: Once the blondies are out of the oven, allow them to cool in the pan for a few minutes. This cooling period is crucial as it allows the blondies to set, making them easier to cut into neat squares. After a short rest, transfer them to a wire rack to cool completely. Once cooled, use a sharp knife to cut them into your desired bar size.





Tips for Blondie Perfection
- Don’t Overmix: When combining the wet and dry ingredients, mix just until combined. Overmixing can develop the gluten in the flour (even from cake mix), leading to tougher blondies. We want them tender and chewy!
- Proper Pan Size: Using the recommended 11×7 inch pan is important for achieving the correct thickness and bake time. If you use a larger pan, your blondies will be thinner and may bake faster; a smaller pan will result in thicker blondies that require more baking time.
- Cool Completely for Clean Cuts: While it’s tempting to dive in immediately, allowing your blondies to cool almost completely before cutting will give you much cleaner, neater squares. The butter and chocolate need time to set.
- Customize Your Sprinkles: While festive red and green sprinkles are perfect for the holidays, feel free to use sprinkles for any occasion – rainbow for birthdays, pastel for spring, or school colors for game day!
- Toasted Nuts for Extra Crunch: For an added layer of flavor and texture, consider folding in ½ cup of toasted chopped pecans or walnuts along with the white chocolate chips.
Serving and Storage Suggestions
These Easy Holiday Blondie Bars are delicious on their own, perhaps with a cup of hot cocoa or coffee. For a more indulgent treat, serve them warm with a scoop of vanilla ice cream and a drizzle of caramel sauce. They make fantastic additions to holiday dessert platters, cookie exchanges, or as edible gifts for friends and neighbors. To store, keep them in an airtight container at room temperature for up to 3-4 days, or refrigerate for up to a week. They can also be frozen for longer storage, simply thaw at room temperature before serving.
