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!

Expert Tips for the Best Christmas Bars
-
Melted Butter: Ensure your unsalted butter is fully melted for a smooth mixture; if it’s too cold, lumps can form in your batter.
-
Pan Preparation: Use non-stick spray or parchment paper to line your baking pan, making it easier to remove your Christmas Bars once cooled.
-
Cooling Time: Allow the bars to cool completely before cutting them into squares; this prevents them from crumbling and retains their chewy texture.
-
Mix-In Mayhem: Don’t hesitate to experiment with mix-ins! Dried fruits, coconut, or even different types of chocolate can elevate your Christmas Bars to new heights.
-
Storage Savvy: Store your bars in an airtight container at room temperature for optimal freshness, or freeze them for future indulgence.

Christmas Bars Recipe FAQs
What should I look for when selecting graham cracker crumbs?
Absolutely! When selecting graham cracker crumbs, look for a consistent color and texture with no dark spots. If you’re making your own, choose whole graham crackers with no added preservatives for the best flavor. A fresh, crunchy base is essential for that delightful texture in your Christmas Bars.
How can I store the Christmas Bars to maintain freshness?
You can store your Christmas Bars in an airtight container at room temperature for up to one week. For optimal texture, ensure they are sealed properly to prevent them from drying out. If you prefer a chilled treat, they can be refrigerated for up to 10 days. Just be mindful that refrigeration can slightly alter the chewy consistency.
Can I freeze Christmas Bars, and how should I do it?

When ready to enjoy, simply thaw at room temperature or microwave individual pieces for about 15 seconds for that freshly-baked feel.
What are some troubleshooting tips for making my Christmas Bars?
Very good question! If your Christmas Bars are crumbling when you cut them, it’s likely due to not letting them cool completely. Allow them to cool for at least 30-45 minutes before cutting for a better texture.
