Ultra-creamy hot chocolate fudge studded with mini marshmallows and silky drizzle. Easy microwave method, cozy winter treat for sharing.

My family calls this the snow-day fudge because I always make it when the forecast turns frosty. The binder-clip trick for lining the pan still makes my sister laugh, and it guarantees crisp edges every time. Even non-bakers feel confident after seeing how quickly it comes together.
My favorite part is the shiny drizzle setting like chocolate ribbons across a snowy marshmallow field. Children love pointing to the biggest marshmallow cap and claiming it as theirs, and the adults always ask for a second square with coffee. The balance between creamy base and fluffy top makes every bite feel like the best part of a winter evening, no mug required.
Refrigerate the sliced fudge in an airtight container lined with parchment to prevent sticking and moisture transfer. Layer with more parchment if stacking. It stays fresh and fudgy for up to 1 week. For longer storage, freeze portions in a freezer-safe container, tightly wrapped and labeled, for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature for 15 to 20 minutes before serving for the best texture. Avoid warm countertops or sunny spots which can soften the marshmallow topping. If condensation forms after thawing, leave the lid slightly ajar for a few minutes to let excess moisture escape.
For a slightly less sweet base, replace 1/2 cup milk chips with semi-sweet chips. No salted butter? Use unsalted butter plus a generous pinch of fine salt. If you only have baking chocolate, chop it finely and use 3 cups total by volume. For the drizzle, coconut oil can replace vegetable oil at a 1:1 ratio for a subtle coconut note. Need a vegetarian option? Choose vegetarian mini marshmallows made without gelatin, and verify the hot chocolate mix is suitable for your needs. If you prefer darker flavor, swap the hot chocolate mix for 2 to 3 tablespoons of Dutch-process cocoa plus 2 to 3 tablespoons powdered sugar.
Serve squares slightly chilled for tidy edges or let them sit out 10 minutes for a softer bite. Arrange on a white platter so the marshmallow topping pops, and sprinkle a little crushed peppermint or a dusting of cocoa for a festive touch. Pair with hot coffee, chai, or peppermint tea. For holiday dessert boards, mix the fudge among ginger cookies, candied oranges, and roasted nuts. When gifting, tuck parchment between layers in a tin and include a handwritten tag with the cutting grid: 5 by 5 squares for perfect portions.
Classic American fudge traces back to late 19th-century candy-making experiments, where cooks discovered that sweetened condensed milk could stabilize chocolate into a creamy, sliceable confection without painstaking sugar stages. This version borrows the beloved winter ritual of hot cocoa, turning a drink into a bite. The addition of marshmallows nods to campfire s’mores and diner-style hot chocolate, blending two nostalgic traditions into a playful, modern treat that feels familiar at first taste.
For autumn, add 1 teaspoon ground cinnamon and a pinch of nutmeg to the base, then top with crushed graham crackers. In December, swap the drizzle for melted white chocolate and finish with crushed peppermint candies. For Valentine’s Day, stir in 1/2 teaspoon espresso powder for depth and sprinkle tiny heart sprinkles on the marshmallows. In summer, press mini graham pieces into the topping and add a quick torch to a few marshmallows for a s’mores vibe. Small changes shift the mood without rewriting the method.
Make the base and topping up to 2 days ahead: prepare and chill the fudge fully, then keep covered in the pan. Drizzle and slice the day you plan to serve for the cleanest lines. If you need bite-size portions, cut into 36 small squares instead of 25. For party platters, separate layers with parchment so the marshmallows remain fluffy. When transporting, keep the container level and chilled with an ice pack. A thin, oiled chef’s knife or warm bench scraper will give you uniform cuts in seconds.
There is something wonderfully simple about a treat that brings a room to a pause. This hot chocolate fudge does exactly that, inviting everyone to reach for one more square. Make it once, and it will become your new winter tradition.
Clip parchment to the pan with binder clips to keep it from folding onto the fudge.
Stir thoroughly between microwave intervals to prevent hot spots and scorching.
Press the top marshmallows gently so they adhere without collapsing.
Let the drizzle set fully before slicing to prevent smearing.
For deeper chocolate flavor, swap 1/2 cup milk chips for semi-sweet chips.

Line an 8x8-inch baking dish with parchment, leaving a 2-inch overhang. Lightly spray with nonstick cooking spray and secure the parchment edges with binder clips to keep the paper flat.
Combine semi-sweet chips, milk chips, sweetened condensed milk, hot chocolate mix, and butter in a medium microwave-safe bowl. Microwave 1 minute, stir, then heat in 45-second bursts, stirring between each, until melted and smooth, about 2 1/2 to 3 minutes total.
Stir in vanilla until fully incorporated and the mixture is glossy and uniform. If small bits remain, microwave 15 seconds more and stir thoroughly.
Stir in 2 cups miniature marshmallows. Microwave 20 to 30 seconds and stir 2 to 3 times to soften the marshmallows slightly without fully melting them.
Pour the fudge into the prepared pan. Use an offset spatula to spread evenly into the corners and tap the pan gently to settle the surface.
Sprinkle the remaining 2 cups miniature marshmallows over the surface and press lightly so they adhere. Cover with plastic wrap and refrigerate until firmly set, about 2 hours.
Remove binder clips and use the parchment overhang to lift the fudge onto a cutting board. If needed, run a thin knife along the edges to release.
Microwave 1/2 cup semi-sweet chips with 2 teaspoons oil for 30 seconds and stir smooth. Drizzle over the marshmallows. Allow to set, then cut into 25 squares (5 by 5). Refrigerate until serving.
