This image shows a square piece of dessert on brown parchment paper with more pieces around it. The dessert has three visible layers: a thick golden-yellow cake base, a bright red jam layer in the middle with some chunks of fruit, and a light beige crumbly top layer with drizzled white icing on top. The white icing is spread unevenly, adding texture and contrast to the red jam. The focus is on the center piece, showing its soft texture and moist jam, while a silver fork is partially visible on the left side. The background is a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

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, walnuts or pecans)

Instructions

  1. Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
  2. Step 2: In a large bowl, whisk together the graham cracker crumbs, cocoa powder, and powdered sugar until well combined and smooth.
  3. Step 3: Pour in the melted butter and sweetened condensed milk. Stir until the mixture is thick and sticky.
  4. Step 4: Gently fold in the mini marshmallows, chocolate chips, and chopped nuts if using, being careful not to overmix.
  5. Step 5: Spread the mixture evenly into a greased baking pan and smooth the top with a spatula.

Tips & Variations

  • For a dairy-free version, substitute melted butter with coconut oil.
  • Use dark chocolate chips for a richer, less sweet bar.
  • Try adding dried cranberries or peppermint pieces for a festive twist.
  • If you prefer a crunchier texture, toast the nuts before adding.

Storage

Store the Christmas bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. Reheat briefly in the microwave if you prefer them warm, but they are delicious served at room temperature.

How to Serve

The image shows a close-up of a square piece of pastry with a golden brown base layer that looks soft and crumbly. On top of this base is a thick, glossy layer of bright red jam that is slightly shiny and uneven, spread generously over the pastry. Scattered over the jam are small pieces of light beige, slightly textured dough. A thin drizzle of white icing covers parts of the jam and dough pieces, giving a smooth, glossy finish. The pastry is on a light brown parchment paper surface with more similar pastries blurred in the background, all set against a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular marshmallows instead of mini marshmallows?

Yes, regular marshmallows work fine, but mini marshmallows distribute more evenly throughout the bars for better texture.

Can I prepare these bars ahead of time?

Absolutely! You can make the bars a day in advance and store them in an airtight container. This allows the flavors to meld and makes cutting easier once chilled.

Notes

  • Feel free to use any type of chocolate chips according to your preference—dark, milk, or white chocolate all work well.
  • Omitting the nuts makes these bars nut-free and suitable for those with nut allergies.
  • Be sure to wait until the bars are completely cool before cutting to ensure clean squares.
  • Storage: Keep bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
