Step‑by‑Step Instructions for Christmas Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures even baking as you prepare your delicious Christmas Bars. While the oven warms up, gather your ingredients and equipment, including a greased 9×13 inch baking pan.
Step 2: Combine Dry Ingredients
In a large mixing bowl, combine graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Stir these dry ingredients together until well blended, ensuring there are no lumps. This mix forms the rich and crunchy base of your Christmas Bars and brings a delightful chocolate flavor.
Step 3: Mix Wet Ingredients
Pour in the melted unsalted butter and sweetened condensed milk to your dry ingredients. Use a spatula to mix thoroughly until everything is combined into a thick and sticky batter. This step is crucial, as the wet ingredients help bind the mixture together for a chewy texture in your Christmas Bars.
Step 4: Fold in Mix-Ins
Gently fold in the mini marshmallows, chocolate chips, and any optional chopped nuts you may want to include. Be careful not to overmix; you want to preserve the texture of the marshmallows for that delightful chewiness. This step will enhance your Christmas Bars with extra flavor and a fun twist.
Step 5: Spread the Mixture
Transfer the mixture into your prepared baking pan. Use your spatula to evenly spread the mixture across the pan and smooth the top. This ensures each piece of your Christmas Bars has a consistent texture and thickness after baking, setting the foundation for a treat everyone will love.
Step 6: Bake the Bars
Place the pan in your preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the edges are set, and the center is slightly firm to the touch. The heavenly aroma of chocolate and marshmallows will fill your kitchen, creating a festive atmosphere as you await the delicious outcome.
Step 7: Cool Completely
Once baked, remove the pan from the oven and allow the Christmas Bars to cool completely in the pan. This cooling phase is essential; if cut too early, the bars may crumble. After about 30-45 minutes, your bars will be ready to cut into squares for a perfect holiday treat!

Make Ahead Options
These festive Chocolate Marshmallow Christmas Bars are perfect for busy home cooks looking to save time! You can prepare the base mixture up to 24 hours in advance by mixing the graham cracker crumbs, cocoa powder, powdered sugar, melted butter, and sweetened condensed milk. Simply store the mixture in an airtight container in the refrigerator to maintain its freshness. When you’re ready to bake, fold in the mini marshmallows and chocolate chips, then spread and bake as instructed. This allows you to enjoy the holiday cheer without the stress of last-minute preparations, resulting in delicious treats that are just as delightful!

Christmas Bars Recipe FAQs
What kind of graham crackers should I use for the base?
You can use store-bought graham cracker crumbs for convenience, or crush whole graham crackers if you prefer a fresher taste. Just ensure that you measure them properly for the best texture!
How should I store my Christmas Bars?
Store your Christmas Bars in an airtight container at room temperature for up to 3 days. If you’d like to keep them fresh for longer, they can be stored in the refrigerator for up to a week. The bars will absorb moisture, so make sure the container is sealed well to maintain that delightful chewiness.
Can I freeze my Christmas Bars?
Absolutely! Wrap each cooled bar in plastic wrap and then place them in a freezer bag. Your Christmas Bars can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw them in the refrigerator overnight or warm them in the microwave for a few seconds—this helps bring back their chewy texture!
What if my bars turn out crumbly instead of chewy?
If your Christmas Bars turn out crumbly, it could be due to overbaking or not using enough moisture. Make sure to bake them until just set and allow them to cool completely in the pan before cutting. If they still seem dry, next time, try adding a touch more sweetened condensed milk for extra moisture.
