For the Chewy Layer
– Sweetened Condensed Milk – Ensures moisture and sweetness, crucial for that chewy texture.

Step‑by‑Step Instructions for Chocolate Marshmallow Christmas Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring that your Chocolate Marshmallow Christmas Bars bake evenly. While the oven warms up, gather your tools: an 9×13 inch baking pan, mixing bowls, and a spatula for easy mixing.
Step 2: Combine Dry Ingredients
In a large mixing bowl, combine graham cracker crumbs, unsweetened cocoa powder, and powdered sugar. Use a whisk to blend the dry ingredients until they are fully combined and the mixture is uniform in color. This creates the sweet, rich base for your bars that will tantalize your taste buds.
Step 3: Mix in Wet Ingredients
Next, stir in the melted unsalted butter and sweetened condensed milk into the dry mixture. Use a sturdy spatula to combine everything until the mixture is thick and homogenous. You’ll know it’s ready when it holds together and looks shiny, setting the stage for those delightful Chocolate Marshmallow Christmas Bars.
Step 4: Fold in the Mix-Ins
Gently fold in the mini marshmallows, chocolate chips, and chopped nuts (if using). Take care not to overmix, as you want to maintain the fluffy texture of the mini marshmallows. The chocolate chips will add bursts of melty goodness, while the marshmallows create that delightful chewy layer.
Step 5: Spread the Mixture
Transfer the bar mixture into the greased 9×13 inch pan. Use a spatula to evenly spread it out, making sure it’s smoothed down to cover the bottom completely. This ensures your Chocolate Marshmallow Christmas Bars bake uniformly, allowing for that perfect chewy texture throughout.
Step 6: Bake the Bars
Place the pan in the preheated oven and bake for 25-30 minutes. Keep an eye on them; they are ready when the edges are set and the center feels slightly firm to the touch. You’ll notice a delectable aroma filling your kitchen, a sign that your holiday treat is on the way!
Step 7: Cool and Cut
Remove the bars from the oven and let them cool completely in the pan. This is key to achieving clean cuts when serving. Once cool, use a sharp knife to slice them into squares. The finished Chocolate Marshmallow Christmas Bars should be perfectly chewy with a rich, chocolatey flavor ready for sharing.

Christmas Bars Recipe FAQs
How do I choose the right graham cracker crumbs?
Absolutely! For the best results, look for graham cracker crumbs that are fresh and free from any dark spots or stale odor. You can easily substitute regular graham crackers by crushing them into fine crumbs at home. For gluten-free options, check that the packaging states “gluten-free” to ensure there are no hidden contaminants.
How should I store my Christmas Bars for freshness?
It’s very important to store your Christmas Bars in an airtight container. At room temperature, they’ll stay fresh for up to 3 days. If you’d like them to last longer, refrigerate them for up to a week. Just be sure to wrap them tightly to prevent dryness or staleness!
Can I freeze Christmas Bars, and how do I do it?
Yes, you can freeze your Christmas Bars with great success! First, let them cool completely. Then, wrap each bar individually in plastic wrap, ensuring they’re well-covered to prevent freezer burn. Place them in a freezer-safe container or bag, and they will stay delicious for up to three months. When you’re ready to enjoy, just thaw them at room temperature or microwave for a few seconds to revive their gooey texture.
What if my bars are too crumbly after baking?
Very common! If your Christmas Bars turn out too crumbly, it’s often due to either too much dry ingredient or not enough butter. Next time, try adding a bit more melted butter and ensure you’re compacting the mixture well into the baking pan. Cooling the bars completely before cutting helps them stay together too, so patience is key here!
Are these Christmas Bars safe for people with allergies?
To make them allergy-friendly, simply omit the chopped nuts if there’s a nut allergy at your gathering. For gluten-free versions, ensure you use certified gluten-free graham cracker crumbs. For vegan options, replace the sweetened condensed milk with a homemade version (like coconut milk mixed with a bit of sugar). Always double-check ingredient labels for potential allergens!
Can I add different mix-ins to my Christmas Bars?
Absolutely! The more the merrier, I often make these with vibrant add-ins. Feel free to incorporate dried fruits like cranberries or cherries, or even a shot of peppermint extract for a minty twist. Just remember to incorporate them gently to keep the fluffy marshmallows intact!
