Christmas Bars Ingredients
For the Base
- Graham Crackers – 2 cups (200 g); the sweet and crunchy foundation for these delicious Christmas bars.
- Cocoa Powder – ¼ cup (25 g); for rich chocolate flavor; opt for high-quality cocoa for the best taste.
- Powdered Sugar – 1½ cups (180 g); sweetens and creates that melt-in-your-mouth texture.
For the Binding
- Unsalted Butter – ¾ cup (170 g, melted); essential for binding and adding richness, though you can swap it with melted coconut oil for a dairy-free option.
- Sweetened Condensed Milk – 14 oz (397 g, 1 can); provides that necessary moisture and chewy consistency essential to these Christmas bars.
For the Mix-ins
- Mini Marshmallows – 3 cups (150 g); these fluffy bites bring a fun, chewy texture; mini ensures even distribution.
- Chocolate Chips – 1½ cups (270 g); adds a chocolate punch, with options including dark, milk, or white chocolate chips.
- Chopped Nuts – ½ cup (60 g, optional); brings extra crunch and flavor; simply omit for a nut-free version or replace with more chocolate chips.
Step‑by‑Step Instructions for Easy Christmas Bars with Chocolate and Marshmallows
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure even baking of your Christmas bars. This initial step is vital as it helps the bars rise and set properly. Make sure to adjust your oven racks to the center position for optimal heat distribution—this will prevent undercooking or burning the edges.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine 2 cups of graham cracker crumbs, ¼ cup of cocoa powder, and 1½ cups of powdered sugar. Whisk them together until fully blended—this ensures the dry ingredients are nicely incorporated. You should see a uniform mixture with no lumps, which will create a smooth texture in your Christmas bars.
Step 3: Add Wet Ingredients
Pour in ¾ cup of melted unsalted butter and 14 oz of sweetened condensed milk into the dry mixture. Stir well until the mixture becomes thick and sticky, resembling a dough-like consistency. This is the base that will hold your Easy Christmas Bars together, so make sure everything is combined without any dry pockets left behind.
Step 4: Fold in Mix-ins
Gently fold in 3 cups of mini marshmallows and 1½ cups of chocolate chips. Be careful not to overmix, as you want to preserve the fluffy texture of the marshmallows. If you’re adding chopped nuts, now is the time to do so. Visualize a harmonious blend of chocolate and fluffy marshmallows—a delightful mix that enhances the flavor of your Christmas bars.
Step 5: Spread and Bake
Transfer the mixture into a greased 9×13 inch baking pan, spreading it evenly with a spatula to ensure uniform thickness. Bake in the preheated oven for 25 to 30 minutes, or until the edges look set and the center is slightly firm but still a bit soft. This will give your Easy Christmas Bars the perfect chewy texture.
Step 6: Cool and Cut
Allow the bars to cool completely in the pan at room temperature. Once they are cool, use a sharp knife to cut them into squares or rectangles. This cooling process is crucial to ensure that your Christmas bars hold their shape and don’t crumble when served. Enjoy the delightful combination of gooey marshmallows and rich chocolate in each bite!

Make Ahead Options
These Easy Christmas Bars are perfect for meal prep enthusiasts seeking to save time during the busy holiday season! You can prepare the base mixture up to 24 hours in advance; simply follow the first four steps of the recipe and refrigerate the mixture in an airtight container. This helps the flavors meld together for an even tastier result. When you’re ready to bake, just spread the chilled mixture into the greased pan and follow the baking instructions as usual. To maintain quality, ensure they cool completely before cutting into squares. By making these bars in advance, you’ll enjoy delicious, homemade treats with minimal effort on the day of your gathering!

Can I freeze Christmas bars for later enjoyment?
Very much! To freeze, first wrap the cooled bars tightly in plastic wrap, ensuring there are no exposed areas. Then place them in a freezer-safe bag or container. They will keep well for up to 3 months. When you’re ready to enjoy, simply thaw them overnight in the fridge and warm them slightly in the microwave if you prefer them gooey again.
What should I do if my Christmas bars are too crumbly?
If you find your Christmas bars are crumbly, make sure you’ve properly mixed the ingredients, particularly the melted butter and sweetened condensed milk. If your bars still crumble, you can try adding a little more melted butter next time to bind them together better. Always ensure they cool completely before cutting them to achieve clean edges!
Are these Christmas bars suitable for people with nut allergies?
Absolutely! You can easily omit the nuts from the recipe altogether. If you’re making them for someone with nut allergies, just be sure to avoid any cross-contamination in your kitchen. I often replace nuts with more chocolate chips for added texture and sweetness without any concern for allergies.
Can I customize the flavors of my Christmas bars?
Very! These bars are incredibly versatile. You can add ingredients like dried fruits, coconut, or even a splash of flavor extracts like peppermint for a festive twist. Just keep the overall quantity of mix-ins around the same so the texture stays consistent. Happy baking!
