Step‑by‑Step Instructions for Christmas Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures the temperature is just right for baking your Christmas Bars evenly. While the oven warms up, gather your ingredients to streamline the preparation process.
Step 2: Combine Dry Ingredients
In a large mixing bowl, combine graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Use a whisk or spatula to ensure all ingredients are fully blended together, creating a uniform dry mixture that will form the tasty base of your Christmas Bars.
Step 3: Add Wet Ingredients
Melt your unsalted butter and allow it to cool slightly before adding it to the dry mixture, along with the sweetened condensed milk. Stir vigorously until the mixture becomes thick, sticky, and well combined, ensuring that everything is incorporated evenly and no dry ingredients remain.
Step 4: Fold in Mix-ins
Gently fold in the mini marshmallows and chocolate chips into your thick batter. If you are using chopped nuts, add them at this stage as well. Be careful not to overmix; you want to keep the marshmallows intact for that delightful chewy texture in your Christmas Bars.
Step 5: Spread & Bake
Pour your batter into a greased 9×13-inch baking pan, smoothing the top with a spatula to ensure even baking. Place the pan in your preheated oven and bake for 25-30 minutes, or until the edges are set and the center looks slightly firm but not overly dry.
Step 6: Cool & Cut
Once baked, remove the pan from the oven and let the Christmas Bars cool completely in the pan. This cooling period is essential for cutting them into neat squares without crumbling. Once cooled, slice into squares and serve to make everyone’s holiday gatherings a little sweeter!

Make Ahead Options
These Festive Christmas Bars are perfect for meal prep enthusiasts! You can create the base mixture up to 24 hours in advance and refrigerate it in an airtight container, which helps to lock in that rich chocolate flavor. Additionally, you can mix in your mini marshmallows and chocolate chips just before baking to maintain their delightful texture. For maximum freshness, bake the bars no more than a day before serving, allowing you to enjoy their luscious, chewy goodness at its best. When you’re ready to serve, simply cut them into squares, and they’ll be just as delicious as if freshly made!

Christmas Bars Recipe FAQs
What type of graham crackers should I use for my Christmas Bars?
Absolutely! For the base, I recommend using traditional honey-flavored graham crackers for a sweet crunch. If you need a gluten-free option, simply substitute with gluten-free graham crackers or even crush almond flour for a unique twist.
How should I store the Christmas Bars after baking?
Keep your Christmas Bars in an airtight container at room temperature for up to one week for optimal freshness. If you want to prolong their shelf life, they can be stored in the fridge for up to 10 days. Allow them to reach room temperature before serving for the best taste!
Can I freeze Christmas Bars for later use?
Sure thing! To freeze, wrap the cooled bars securely in plastic wrap, then place them in a freezer-safe container. They will keep well for up to three months. When you’re ready to enjoy them, simply thaw them in the fridge overnight, and if you like, a quick 10-15 seconds in the microwave can bring back that warm, gooey texture!
What if my Christmas Bars are too crumbly after baking?
If your bars crumble, it’s usually due to not allowing them to cool completely or possibly having too much dry ingredient in the mixture. To achieve a perfect, chewy texture, ensure that the mixture is well combined before baking, and let them cool in the pan before cutting. Next time, try gently pressing the mixture into the pan to create a denser base!
Are there any common dietary considerations with Christmas Bars?
Definitely! If you’re concerned about allergies, you can make these bars nut-free by omitting the nuts or using substitutes like sunflower seeds. For those avoiding dairy, simply substitute the unsalted butter with melted coconut oil and look for a vegan condensed milk option. Everyone can indulge in these festive treats!
How can I customize the flavor of my Christmas Bars?
The more the merrier! You can easily add your favorite flavors to the mix. Stir in peppermint extract for a delightful mint chocolate twist or fold in dried fruits like cranberries or cherries for a fruit medley.
