Step‑by‑Step Instructions for Christmas Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This essential step ensures that your Christmas bars bake evenly, achieving that perfect fudgy consistency. While the oven heats up, gather your 9×13 inch baking pan and grease it generously to prevent sticking, ensuring the bars release easily once baked.
Step 2: Mix the Dry Ingredients
In a spacious mixing bowl, whisk together the graham cracker crumbs, unsweetened cocoa powder, and powdered sugar until the mixture is well combined. Aim for a uniform texture that allows the flavors to blend beautifully. The combination of the chocolatey cocoa and sweet graham cracker will fill your kitchen with a comforting aroma as you prepare your delightful Christmas bars.
Step 3: Combine Wet Ingredients
Next, pour in the melted unsalted butter (or coconut oil for a dairy-free option) along with the sweetened condensed milk. Stir until everything is thoroughly combined, creating a thick and sticky batter. This mixture should appear smooth and glossy, reflecting the richness of the bars you are about to create, and making it irresistible to anyone nearby.
Step 4: Fold in the Marshmallows and Chocolate
Gently fold in the mini marshmallows and chocolate chips, taking care not to break the marshmallows. This step is crucial as it ensures every bite of your Christmas bars is packed with chewy marshmallow goodness and decadent chocolatey flavor. If you’re opting for nuts, now is the time to incorporate them into the mixture for an added crunch.
Step 5: Spread the Mixture
Pour the luscious mixture into the prepared baking pan. Using a spatula, spread it evenly to create a flat surface, ensuring that the mixture reaches all corners of the pan. The smooth top will give a lovely finish to your Christmas bars, inviting everyone to take a bite once they’re baked.
Step 6: Bake the Bars
Place the baking pan in the preheated oven and bake for 25 to 30 minutes. Keep an eye on the edges; they should be set while the center remains slightly soft and firm to the touch. This slight give will contribute to the perfect, chewy texture of your Christmas bars, allowing them to maintain their festive appeal.
Step 7: Cool and Cut
After baking, remove the pan from the oven and let the bars cool completely in the pan. This step is essential; cooling ensures they firm up and hold together beautifully when cut. Once fully cooled, use a sharp knife to cut the bars into squares, making them manageable for serving or gift-giving during the holiday festivities.

Make Ahead Options
These Easy Chocolate Marshmallow Christmas Bars are perfect for meal prep, saving you precious time during the busy holiday season! You can bake the bars up to 2 days in advance; simply allow them to cool completely and store them in an airtight container at room temperature to maintain their delicious chewiness. If you’d like to prepare the mixture ahead, combine the dry ingredients and store them in a sealed bag or container for up to 24 hours. When ready to bake, just mix in the wet ingredients and follow the remaining steps. By prepping ahead, you’ll ensure that your Christmas bars are fresh and just as delightful when it’s time to serve!

What should I do if my bars crumble when cutting?
Oh no! To prevent crumbling, ensure the bars are completely cooled in the pan before cutting. Additionally, using a sharp knife and making gentle, straight cuts can help maintain their shape.
