Step‑by‑Step Instructions for Christmas Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to ensure even baking of your Easy Chocolate Marshmallow Christmas Bars. This crucial step helps achieve a perfect texture, so don’t skip it! While the oven heats, gather your baking equipment, including a greased 9×13 inch baking pan and mixing bowls for the ingredient preparation.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Use a whisk to blend these dry ingredients thoroughly until there are no lumps. This step creates a sweet, chocolatey base for your bars, setting the stage for the richness to come.
Step 3: Add Wet Ingredients
Once your dry ingredients are combined, pour in the melted unsalted butter and sweetened condensed milk. Stir the mixture with a spatula until it becomes thick and sticky, ensuring everything is well incorporated. The mixture should look smooth and slightly glossy, indicating that your Easy Chocolate Marshmallow Christmas Bars will have a delightful chewy texture.
Step 4: Fold in Mix-ins
Gently fold in the mini marshmallows and chocolate chips, ensuring they are evenly distributed within the mixture. Be careful not to overmix, as you want those marshmallows to maintain their fluffy texture. If using, add your chopped nuts at this stage. The combination of flavors will elevate the enjoyment of your Christmas bars.
Step 5: Spread and Bake
Pour the mixture into your prepared greased baking pan, smoothing the top with a spatula for an even surface. Bake in the preheated oven for 25-30 minutes. The edges should look set, while the center remains slightly firm but not jiggly. This balance ensures your bars will have that perfect soft, chewy texture when cooled.
Step 6: Cool and Cut
After baking, remove the pan from the oven and allow it to cool completely at room temperature. Once cooled, carefully slice the Easy Chocolate Marshmallow Christmas Bars into squares for serving. Cutting them when fully cooled prevents crumbling and makes for beautiful, tempting treats ready to delight your friends and family.

Christmas Bars Recipe FAQs
How do I select the right graham cracker crumbs?
Absolutely! When choosing graham cracker crumbs, look for a finely ground product for the smoothest texture in your bars. You can also use whole graham crackers and crush them yourself. Simply place them in a resealable bag and use a rolling pin to crush them into fine crumbs. This is a great option if you want a bit more crunch in your bars!
How should I store my Christmas bars?
Very! Store your Christmas bars in an airtight container at room temperature for up to 1 week. For added freshness, you can refrigerate them, where they’ll keep for about 2 weeks. Just make sure to wrap them tightly to prevent moisture from making them soggy.
Can I freeze my Christmas bars?
Absolutely! To freeze your Christmas bars, start by cutting them into squares and placing them in a well-sealed freezer-safe container. You can also wrap each piece in plastic wrap to protect them from freezer burn. They’ll stay fresh for up to 3 months! When you’re ready to enjoy, thaw them at room temperature for about 30 minutes for that perfect chewy texture.
What should I do if my bars are too crumbly?
No worries! If your bars turn out too crumbly, it may be due to insufficient binding ingredients. Ensure your butter is completely melted before mixing, as this helps bind everything together. Adding a little more sweetened condensed milk can also help. If you’re finding it hard to keep the bars together, consider pressing the mixture into the pan more firmly or tweaking the dry ingredients slightly.
Are these bars safe for pets?
Great question! Since these Christmas bars contain ingredients like chocolate and sweetened condensed milk, they should not be given to pets. Chocolate is toxic to dogs and cats, so it’s best to keep your festive treats away from furry friends. Always check for allergens if you’re sharing with family or friends who might have dietary restrictions.
