Sweet Christmas Bars

When a baking session turns into a whole event, it’s usually thanks to a recipe like these Christmas bars. We were decorating the tree in my cousin’s apartment downtown her toddler tugging at garlands, her partner balancing on a chair to hang that one uneven star when I brought these bars out in a festive tin. You could smell the cocoa before the lid even came off. Her neighbor, who dropped by for just five minutes, ended up staying for tea and two servings.

A few days later, I made another batch while my niece was over helping me wrap gifts. She stirred the marshmallows into the gooey base like it was edible magic, announcing, “It smells like a chocolate blanket!” That same night, my elderly neighbor slipped one into her coat pocket “for later,” then winked at me from her porch. These bars have a way of turning small December moments into something a little more golden.

They’re rich, chewy, and just messy enough to feel indulgent without making you babysit them in the oven. Whether you’re sharing them with coworkers, slipping them into stockings, or enjoying one quietly with your coffee while everyone else is asleep, Christmas bars feel like a little reward tucked inside the season.

Short Description

These chewy Christmas bars are rich with chocolate, studded with mini marshmallows, and incredibly easy to make with pantry staples. Perfect for parties, gift boxes, or cozy nights in.

Key Ingredients

• 2 cups (200 g) graham cracker crumbs
• ¼ cup (25 g) unsweetened cocoa powder
• 1½ cups (180 g) powdered sugar
• ¾ cup (170 g) unsalted butter, melted (or ¾ cup / 150 g melted coconut oil for dairy-free)
• 1 can (14 oz / 397 g) sweetened condensed milk
• 3 cups (150 g) mini marshmallows
• 1½ cups (270 g) chocolate chips (dark, milk, or white)
• ½ cup (60 g) chopped nuts (optional)

Tools Needed

• Mixing bowls
• Rubber spatula
• 9×13 inch baking pan
• Measuring cups and spoons
• Whisk or fork
• Oven

Cooking Instructions

Step 1: Preheat the Oven
Set your oven to 350°F (175°C). Grease a 9×13 inch pan or line with parchment paper to prevent sticking.

Step 2: Mix Dry Ingredients
In a large bowl, combine graham cracker crumbs, cocoa powder, and powdered sugar. Whisk or fork to break up any clumps and blend the flavors evenly.

Step 3: Add Wet Ingredients
Pour in the melted butter and sweetened condensed milk. Stir until everything is well incorporated. The mixture will be thick and sticky—that’s a good sign.

Step 4: Fold in Mix-ins
Gently fold in the mini marshmallows, chocolate chips, and optional chopped nuts. Mix just until everything is distributed.

Step 5: Spread and Bake
Spread the mixture evenly in your prepared pan. Press it gently with a spatula to level the surface. Bake for 25–30 minutes until the edges are set and the center is firm.

Step 6: Cool and Cut
Let the bars cool completely in the pan before slicing. Cut into squares or rectangles, depending on your serving style.

Mistakes to Avoid & Solutions

Overbaking
The edges become too hard and dry.
Solution: Bake until just set; the center can look slightly soft. It will firm up as it cools.

Skipping the parchment
Bars stick to the pan and break apart.
Solution: Use parchment or grease the pan thoroughly for clean slices.

Uneven mixing
Pockets of dry crumbs or overly melted marshmallows.
Solution: Mix gently and thoroughly, folding instead of stirring too hard.

Using regular marshmallows
The bars don’t hold together well.
Solution: Use mini marshmallows they melt more evenly and hold the structure.

Cutting too soon
Bars fall apart or stick to the knife.
Solution: Wait until fully cool. Use a sharp knife wiped clean between cuts.
