Step‑by‑Step Instructions for Festive Christmas Bars with Rich Chocolate and Cheerful Marshmallows
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to prepare for baking the Christmas bars. This ensures an even bake, creating that perfect chewy texture. While the oven heats, gather your mixing bowls and a 9×13 inch baking pan for the next steps.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Whisk these dry ingredients together until they’re well mixed and no clumps remain. This will create a uniform base for your Christmas bars, setting the stage for their rich chocolate flavor.
Step 3: Add Wet Ingredients
Next, stir in the melted unsalted butter and sweetened condensed milk into your dry mix. Use a spatula to combine until the mixture is thick and sticky. This step is crucial for binding all the components together, making sure every bite of your Christmas bars is deliciously rich.
Step 4: Fold in Mix-ins
Now, gently fold in the mini marshmallows, chocolate chips, and any optional chopped nuts. Use a spatula to incorporate these mix-ins evenly without overmixing, as you want those marshmallows and chocolate to be well-distributed throughout the batter for the best flavor in every square.
Step 5: Spread and Bake
Pour the mixture into your greased 9×13 inch baking pan, smoothing the top evenly with a spatula. Bake in the preheated oven for 25-30 minutes until the edges are set and the center feels slightly firm to the touch. This will ensure that your Christmas bars have a delightful chewy texture.
Step 6: Cool and Cut
Once baked, remove the pan from the oven and allow the bars to cool completely in the pan. This process will take about 30 minutes. Once cooled, cut them into squares to serve. Proper cooling is essential to prevent crumbling and ensures each piece holds its shape, showcasing your festive Christmas bars beautifully.

Christmas Bars Recipe FAQs
What kind of graham cracker crumbs should I use for Christmas bars?
You can use regular graham cracker crumbs for a classic taste, but if you’re looking for a gluten-free option, I recommend using crushed gluten-free graham crackers or almond flour. Both alternatives work wonderfully, keeping the bars flavorful and allowing everyone to enjoy them!
How should I store my Christmas bars to keep them fresh?
Store your Christmas bars in an airtight container at room temperature for up to 1 week. If you want them to last longer, you can refrigerate them to maintain freshness, which allows them to stay good for up to 2 weeks, although they may be a bit firmer in texture.
Can I freeze Christmas bars, and if so, how?
Absolutely! You can freeze your Christmas bars for up to 3 months. Just wrap them tightly in plastic wrap, then place them in an airtight container to protect against freezer burn. When you’re ready to indulge again, simply thaw at room temperature for about an hour, and they’ll be as delectable as fresh!
What if my Christmas bars crumble when I cut them?
If your bars crumble when cutting, it might be due to not allowing them to cool completely in the pan. Make sure to let them cool for at least 30 minutes. When they’re cool, use a sharp knife and cut slowly for cleaner edges. You can also try refrigerating them briefly prior to cutting for better results.
Are there any dietary considerations I should keep in mind for Christmas bars?
Yes indeed! You can easily make nut-free or gluten-free versions by choosing appropriate substitutes, like leaving out the nuts or using gluten-free graham crackers. For a vegan option, swap the butter for coconut oil and opt for a dairy-free sweetened condensed milk. Always check labels for potential allergens like nuts and dairy if you have guests with dietary restrictions.
What can I pair with my Christmas bars for serving?
I love serving Christmas bars with hot cocoa or spiced apple cider for a cozy treat! You could also go indulgent by pairing them with vanilla ice cream. For presentation, dust with powdered sugar or arrange them on a festive platter with mint leaves or berries for a beautiful touch!
