Festive Christmas Bars
A snowstorm was brewing the night Ella texted me a photo of her countertop chaos bowls, sprinkles, and two toddlers covered in flour. Her oldest had begged for something “chocolatey and chewy,” and she needed a recipe fast. We landed on Christmas Bars, the kind that melt into fudgy bliss with bits of crunch and a swirl of nostalgia.
Over in Denver, my cousin Jun made a batch on a whim during a gift-wrapping marathon, pressing marshmallows into place while reruns of classic holiday cartoons played in the background. And in our own kitchen last December, we made trays of these bars for the school bake sale. My daughter lined up the chocolate chips with tweezers because “they have to sparkle.”
What makes Christmas Bars so irresistible is how quickly they come together while still delivering layers of texture. Think soft, cocoa-kissed base, creamy condensed milk, gooey marshmallows, and melty chips in every bite. They travel well, freeze beautifully, and taste like the holidays. Whether you’re baking with kids, prepping for a party, or just craving a little sweetness while watching snowflakes fall, this recipe meets the moment.

Cooking Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease or line a 9×13 inch baking pan with parchment paper.
Step 2: Mix the Dry Base
In a large bowl, stir together the graham cracker crumbs, cocoa powder, and powdered sugar until evenly combined.
Step 3: Add the Wet Ingredients
Pour in the melted butter and the sweetened condensed milk. Stir well until the mixture forms a thick, sticky dough.
Step 4: Fold in the Add-Ins
Gently fold in the mini marshmallows, chocolate chips, and optional chopped nuts. Make sure everything is evenly distributed.
Step 5: Bake
Spread the mixture evenly into the prepared pan. Smooth the top with a spatula. Bake for 25–30 minutes, or until the edges look set and the top is slightly firm.
Step 6: Cool and Slice

Mistakes to Avoid & Solutions
Too dry or crumbly
If your bars seem dry, it’s likely too little sweetened condensed milk or overbaking. Check your oven at 25 minutes and adjust if needed.
Sticky mess when cutting
Let the bars cool completely. For cleaner cuts, chill them briefly and use a sharp knife wiped between slices.
Uneven bake
Spread the mixture evenly in the pan and avoid overmixing. A metal pan also helps distribute heat more evenly than glass.
Chocolate chips sinking
Toss the chips in a little bit of the dry mix before folding them in—this keeps them from sinking straight to the bottom.
Burnt edges
Oven temps vary. If your edges bake faster than the center, tent loosely with foil halfway through to avoid overbrowning.

Storage and Reheating Tips

If desired warm, microwave a square for 10 seconds for a melty finish
FAQs
1. Can I make these Christmas Bars ahead of time?
Yes, these bars hold up beautifully. Make them 2–3 days in advance and store in the fridge or freeze for later.
2. Can I make this recipe dairy-free?
Absolutely! Swap the butter for melted coconut oil and use a dairy-free condensed milk alternative.
3. Do I have to use marshmallows?
No, but they add that gooey, festive charm. You can leave them out or replace them with dried cranberries or crushed peppermint.
4. What’s the best type of chocolate chips?
Dark chocolate gives a nice contrast to the sweetness, but you can mix and match with white, semi-sweet, or even festive red-and-green candies.
5. How do I keep the bars from sticking to the pan?
Line your baking dish with parchment paper or generously grease it with butter or spray. Let them cool before slicing.

These Christmas Bars aren’t fussy, but they show up with that same generous spirit as a handmade gift or a warm dish passed between friends.
