Christmas Sweet Treats — Quick, Chewy Christmas Bars That Steal the Show

If you crave Christmas Sweet Treats that hit every holiday note — chocolate, gooey marshmallows, and a little crunchy surprise — these Christmas bars are exactly what you need. They come together fast, feed a crowd, and keep well, which makes them a lifesaver when you’re juggling gift lists and playlists. Ready to make something ridiculously good with minimal fuss?

Brief introduction to the recipe

Think chewy, chocolate-forward bars loaded with marshmallows and melty chips. They bake up in under an hour and slice into snackable squares that taste like a cozy holiday hug. These bars are simple enough for weeknight baking but pretty enough for a cookie exchange. Basically: big flavor, zero drama.

Why you’ll love these bars

  • Speed: These bars take about 45 minutes from start to finish — perfect for last-minute hosts.
  • Texture party: You get a crunchy graham base, fudgy body, and little pockets of gooey marshmallow. Yum.
  • Customizable: Nuts, dried fruit, even peppermint — tweak them to match your vibe.
  • Crowd-pleaser: Kids adore them, adults steal them, leftovers vanish fast.

The story behind this recipe

I wrote this recipe on a night when I needed dessert pronto for an impromptu holiday movie marathon. I wanted something nostalgic, portable, and low-fuss. I riffed on s’mores bars and chocolate squares, kept the pantry staples, and landed on a formula that always works. Since then, these bars have shown up at potlucks, office parties, and late-night Xmas Food raids. True story: a neighbor once offered me cookies in exchange for the recipe. I gave it up willingly.

Ingredients breakdown (short blurbs)

Here’s what you’ll need and why each part matters.

  • 2 cups graham cracker crumbs (200 g): The crunchy base that keeps everything together. You can blitz whole crackers in a food processor.
  • ¼ cup unsweetened cocoa powder (25 g): Adds chocolate depth without extra sweetness. Use a decent cocoa — it shows.
  • 1½ cups powdered sugar (180 g): Sweetens and gives that melt-in-your-mouth vibe in the filling.
  • ¾ cup unsalted butter, melted (170 g): Binds crumbs and adds richness. Swap coconut oil for a dairy-free option.
  • 1 can sweetened condensed milk (14 oz / 397 g): The secret chewy glue. Don’t skip it.
  • 3 cups mini marshmallows (150 g): Mini marshmallows melt just enough for soft pockets of chew.
  • 1½ cups chocolate chips (270 g): Pick your fave — dark, milk, or white. They boost the chocolate factor.
  • ½ cup chopped nuts (60 g), optional: Walnuts or pecans add crunch. Leave out for a nut-free tray.

Quick substitution tip: For a gluten-free version, use gluten-free graham crumbs or almond flour. If you want a fruity twist, toss in dried cranberries — a great nod to Cranberry Recipes.

How to make these Christmas bars — step by step

Short, clear, and totally doable.

  1. Preheat & prep. Preheat your oven to 350°F (175°C). Grease a 9×13-inch pan or line it with parchment paper for easy lifting.
  2. Mix the dry base. Stir graham cracker crumbs, cocoa powder, and powdered sugar in a large bowl until evenly combined. The mixture should look uniform and chocolatey.
  3. Add butter and condensed milk. Pour the melted butter and the can of sweetened condensed milk into the dry mix. Stir until everything forms a thick, slightly sticky mass. This is your bar batter — it should hold together when pressed.
  4. Fold in mix-ins. Gently fold in the mini marshmallows, chocolate chips, and nuts if using. Don’t overwork it — keep the marshmallows whole for texture.
  5. Press into pan. Transfer the mixture to the prepared pan and press it down evenly with the back of a spatula. Make sure corners are filled and the top is level.
  6. Bake. Bake for 25–30 minutes. You want set edges and a slightly firm center. Keep an eye on them — every oven runs its own race.
  7. Cool & cut. Remove from oven and let cool completely before slicing. I know — impatient, but cooling prevents crumbly slices. Use a sharp knife and wipe it between cuts for clean squares.
  8. Serve. Arrange on a platter and serve with hot cocoa or a scoop of vanilla ice cream.

Pro tip: Let the tray cool fully before cutting. This helps the bars hold their shape and look neat.

Pro tips for perfect results

  • Measure dry ingredients accurately. Scooping flour-like ingredients can compact them — spoon and level.
  • Melt the butter completely. No little chunks — melted butter ensures even mixing.
  • Don’t overbake. Slightly underbaked centers stay chewy; overbaked becomes cakey.
  • Chill briefly for easier cutting. Pop the pan in the fridge for 20–30 minutes if you want super clean slices.
  • Swap-ins: Use peppermint chips for a festive zip or swap half the chocolate chips for butterscotch for a twist.
  • If you’re nut-free, add extra chocolate chips or toasted coconut for texture instead.

Variations to try (make them yours)

Want to turn these into a themed platter? Here are fun riffs.

  • Nut-free Christmas Cookie Bars: Omit nuts and add crushed peppermint candies for crunch. Great for school parties.
  • Gluten-free bars: Use gluten-free graham or almond meal as a base. They’re just as satisfying.
  • Vegan version: Replace butter with coconut oil and use sweetened condensed coconut milk to mimic the chew.
  • Mint-chocolate: Add 1 tsp peppermint extract and swap half the chips for mint chips — minty goodness.
  • Cranberry-chocolate bars: Fold in ¾ cup dried cranberries for a festive tart pop — perfect if you love Cranberry Recipes.
  • Candy overload: Top with chopped holiday candy or crushed candy canes — because why not?

Best ways to serve these bars

  • Party platter: Arrange small squares on a festive board with cookies and fruit.
  • With a warm drink: Pair with hot chocolate or mulled cider for max cozy factor.
  • Dessert trio: Serve a bar with a scoop of ice cream and a drizzle of chocolate sauce.
  • Giftable: Stack squares in a box with parchment between layers for neighbor gifts.

Serving secret: Warm a single square in the microwave for 10–12 seconds — it tastes like fresh-baked heaven.

Quick tips for storage and leftovers

  • Room temp: Store in an airtight container for up to 5 days. They stay chewy.
  • Refrigerator: Keep in the fridge for up to 10 days. Let them come to room temp before serving if you want softer texture.
  • Freezing: Wrap slices tightly and freeze up to 3 months. Thaw in the fridge overnight.
  • Re-crisp hack: If the base gets too soft after refrigeration, pop individual squares in a 350°F oven for 4–5 minutes to refresh.

FAQs — quick answers (because I know you’ll ask)

Can I make these ahead?

Yes — make them a day or two early. Flavors meld and texture stays great. Perfect for busy holiday hosting.

Are these bars kid-friendly?

Totally. They’re a hit with kids because of the gooey marshmallows and sweet chocolate. Just watch for nut allergies.

Can I swap graham crackers for something else?

Absolutely. Use crushed shortbread, digestive biscuits, or gluten-free crumbs to change the base profile.

How do I make them less sweet?

Try using semi-sweet or dark chocolate chips and reduce powdered sugar by a couple of tablespoons. Balance with a pinch of sea salt on top.

Do these count as a cookie?

Funny question — they live in the same dessert family but call them Christmas Cookie Bars if you want people to title them fancy at parties. 😉

Final thoughts — wrap-up and a little push to bake

These bars balance speed and nostalgia like pros. They fit right into your arsenal of Christmas Baking Recipes and make a killer addition to any Christmas Food Desserts table. Whether you label them Easy Christmas Treats for the bake sale or present them as luxe Christmas Candy Recipes at a dinner party, they’ll disappear fast.

So here’s my challenge: make a batch this weekend. Bring them to a gathering, taste-test with friends, or hide them for a midnight snack. You’ll come back to this recipe every year — it’s that reliable.

FYI: if you try the cranberry variation, snap a photo and gloat a little. IMO, tart dried cranberries make these bars shine.

Happy baking and may your kitchen smell like cinnamon and victory. 🎄🍫

Description

Bright, chewy, and choc-full of holiday cheer, these Christmas bars stack texture and flavor into every bite. Ready in under an hour, they’re perfect for gifting, potlucks, or sneaky midnight snacks.


Ingredients

Scale
  • 2 cups (200 g) graham cracker crumbs — the crunchy foundation; crush whole crackers if you don’t have crumbs.
  • ¼ cup (25 g) unsweetened cocoa powder — gives honest chocolate depth. Use a good-quality cocoa if possible.
  • 1½ cups (180 g) powdered (confectioners’) sugar — smooth sweetness that helps bind the mixture.
  • ¾ cup (170 g) unsalted butter, melted — richness and cohesion. Swap ¾ cup (150 g) melted coconut oil for a dairy-free option.
  • 1 can (14 oz / 397 g) sweetened condensed milk — the chewy, caramel-like glue of these bars.
  • 3 cups (150 g) mini marshmallows — tiny pockets of gooey joy; regular marshmallows work too but won’t distribute as evenly.
  • 1½ cups (270 g) chocolate chips — pick dark, milk, or white depending on your mood.
  • ½ cup (60 g) chopped nuts (optional) — walnuts or pecans add crunch; omit for nut-free snacks.


Instructions

  1. Heat the oven. Preheat to 350°F (175°C) and prepare a 9×13-inch pan (grease it or line it with parchment).
  2. Combine the dry base. In a large bowl, whisk together graham crumbs, cocoa, and powdered sugar until the mix looks uniform.
  3. Add the liquids. Pour in the melted butter and the entire can of sweetened condensed milk. Stir until the mixture becomes thick and sticky — it should hold when pressed.
  4. Fold in the goodies. Gently stir in the mini marshmallows, chocolate chips, and nuts (if using). Keep the marshmallows intact so you get those melty pockets.
  5. Press into the pan. Transfer the mixture to the prepared pan and press it down evenly with a spatula or the bottom of a measuring cup. Smooth the surface.
  6. Bake. Slide the pan into the oven and bake 25–30 minutes, until the edges set and the center looks mostly firm. Don’t let it dry out.
  7. Cool completely. Remove from the oven and let the bars cool fully in the pan — patience here gives you clean slices.
  8. Slice and serve. Use a sharp knife (wipe between cuts for neat edges) and cut into squares. Serve at room temperature.

Bold tip: Cool the tray completely before cutting — this keeps the bars from crumbling.


Notes

  • Want variations? Add crushed candy canes or dried cranberries for a festive pop, or swap some chocolate chips for butterscotch for a sweeter twist.
  • Storage: Keep in an airtight container at room temperature for up to 5 days, refrigerate for longer freshness, or freeze individual squares for up to 3 months.
