Gather Your Ingredients

  • Graham cracker crumbs: provide the cookie-like foundation and a light crunch look for fresh whole crackers to crush at home for best flavor
  • Powdered sugar: creates a smooth melt-in-your-mouth sweetness sift to remove lumps
  • Unsalted melted butter: binds everything and adds rich flavor choose high quality for best results
  • Mini marshmallows: add delightful chewiness and a playful touch fresh and soft marshmallows melt best
  • Chocolate chips: bring out chocolate richness choose dark milk or white and grab a quality brand for optimal flavor
  • Unsweetened cocoa powder: boosts chocolate flavor opt for premium cocoa for a deeper taste
  • Chopped nuts (optional): for nutty crunch walnuts or pecans work well just make sure they are fresh
  • Sweetened condensed milk: creamy and sweet it holds the bars together use fresh for best results

How to Make It

Preheat the Oven:
Set your oven to three hundred fifty degrees Fahrenheit one hundred seventy five degrees Celsius before starting anything else. This prep ensures your bars bake evenly and develop that perfect texture throughout.
Prepare the Crumb Base:
In a large mixing bowl combine the graham cracker crumbs powdered sugar cocoa powder and a pinch of salt if using. Whisk thoroughly to break up clumps and create a uniform base. Your kitchen should already smell like chocolate heaven.
Mix in Wet Ingredients:
Pour in melted butter and sweetened condensed milk. Stir patiently until the dry ingredients are moistened and the mixture is thick and sticky. The goal is an even texture throughout so every bar gets the same flavor punch.
Add the Marshmallows and Chocolate:
Gently fold in the mini marshmallows and chocolate chips. You want every square inch to grab a bit of both. If you use nuts add them now lightly tossing to distribute everything evenly.
Spread in Pan and Bake:
Line a nine by thirteen inch pan with parchment or grease with butter. Spread the thick mixture into an even layer. Packing it gently ensures solid bars once baked. Smooth the top with a spatula for a polished finish. Bake for twenty five to thirty minutes until the edges are set and the center no longer appears wet.
Cool and Slice:
Remove from the oven and let the bars cool completely before you attempt to cut them. Resist the urge to rush this step. Cooling keeps the bars from crumbling. When ready use a sharp knife to cut into small festive squares for easy sharing.

One of my favorite memories is seeing my daughter sneak the marshmallows straight from the mixing bowl. Our family tradition now includes leaving a plate of these bars out for Santa every year and there are never any leftovers the next morning.

Flavor Boosters

Mix in dried cranberries or chopped candied ginger for a holiday sparkle. Add peppermint extract or crushed candy canes for a wintery mint twist. Swirl caramel or white chocolate before baking for a luxurious upgrade.

Serving Suggestions

Pile the bars high on a decorative platter with a dusting of extra powdered sugar for a snowy look. Serve with mugs of spiced cider or peppermint tea for a full holiday experience. For a decadent dessert layer bars with vanilla ice cream and drizzle with chocolate syrup.

Creative Twists

Swap regular graham crackers for gluten free versions or ground almond flour for a gluten free twist. Use coconut oil in place of butter for a dairy free recipe. Opt for your favorite chocolate chunks or leftover holiday candies. Mini marshmallows can be replaced with chopped large marshmallows if needed.

If you are prepping these for gifting or a party make a double batch. I have yet to see anyone turn down seconds and these go quickly when set next to a mug of hot cocoa. The smell alone is enough to get everyone into the kitchen and the cheerful bars are always the first dessert to disappear from our holiday table.

What You Need

→ Base Layer

01 2 cups graham cracker crumbs
02 1 1/2 cups powdered sugar
03 3/4 cup unsalted butter, melted
04 1/4 cup unsweetened cocoa powder

→ Mix-ins

05 3 cups mini marshmallows
06 1 1/2 cups chocolate chips
07 1/2 cup chopped nuts (optional)

How to Make It

Step 01

Preheat oven to 350°F. Ensure the oven is fully preheated before baking for even results.

Step 02

In a large mixing bowl, whisk together graham cracker crumbs, cocoa powder, and powdered sugar until well combined and free of lumps.

Step 03

Pour melted butter into the dry mixture. Stir using a sturdy spoon or spatula until evenly moistened. The mixture will be thick and sticky.

Step 04

Fold in mini marshmallows, chocolate chips, and chopped nuts if using. Mix just until evenly distributed. Do not overmix to preserve marshmallow texture.

Step 05

Lightly grease a 9x13 inch baking pan with non-stick spray or line with parchment paper. Spread the mixture evenly across the pan and press gently to level the surface using a spatula.

Step 06

Place the pan on a middle oven rack and bake for 25 to 30 minutes, or until the edges look set and the center is slightly firm to the touch.

Step 07

Remove the pan from the oven and allow to cool completely in the pan. Once cooled, cut the bars into 40 even squares with a sharp knife.

Extra Tips

  1. Let the bars cool completely before cutting to avoid crumbling and achieve clean edges.
  2. For easy removal, line your baking pan with parchment paper, leaving an overhang for lifting.
  3. These bars can be prepared up to two days ahead and stored in an airtight container at room temperature or refrigerated for prolonged freshness.
  4. For a dairy-free version, substitute butter with melted coconut oil. For gluten-free needs, use gluten-free graham crackers in place of regular.
  5. Get creative with mix-ins: try dried cranberries, toasted coconut, or a splash of peppermint extract for a festive variation.
