Step‑by‑Step Instructions for Christmas Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C), ensuring a consistent baking temperature for your Christmas bars. This is crucial for achieving that perfect texture—soft in the middle yet slightly firm on the edges. Gather an 8×8-inch baking pan and have it ready, greasing it lightly to prevent sticking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Whisk these dry ingredients together until they are fully blended, creating a uniform chocolatey mixture. This foundation is essential for the sweet and crunchy base of your Christmas bars.
Step 3: Combine Wet Ingredients
Next, add the melted unsalted butter and sweetened condensed milk to the dry mixture in the bowl. Stir well with a spatula until everything is thoroughly combined and forms a sticky, cohesive mixture. This step is key for the chewy texture we all love in these festive Christmas bars.
Step 4: Fold in Mix-ins
Carefully fold in the mini marshmallows, chocolate chips, and any chopped nuts if you’re using them. Mix gently to avoid crushing the marshmallows while ensuring all ingredients are evenly distributed. This will keep your Christmas bars wonderfully fluffy and delightful with every bite.
Step 5: Spread and Bake
Transfer the mixture into your prepared baking pan, spreading it evenly with your spatula. Bake in the preheated oven for 25 to 30 minutes, or until the edges are set, and the center is slightly firm to the touch. This will ensure your Christmas bars bake to gooey perfection without becoming too dry.
Step 6: Cool and Cut
Once baked, take the pan out of the oven and allow your Christmas bars to cool completely at room temperature. This cooling time is crucial, as it allows the bars to firm up, making them easier to cut into squares. Once cooled, cut them into squares for serving, and enjoy the festive cheer they bring!

How to Store and Freeze Christmas Bars
Room Temperature: Store your Christmas bars in an airtight container at room temperature for up to a week, ensuring they stay fresh and chewy for delightful snacking.
Fridge: If you prefer a colder treat, keep them in the fridge; they can hold their flavor for up to 10 days while maintaining their chewy texture and deliciousness.
Freezer: For longer storage, wrap the bars tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to three months—perfect for holiday treats anytime!
Reheating: To enjoy your bars warm, simply thaw them in the fridge overnight, then pop them in the microwave for a few seconds, bringing back that fresh-baked joy.
