Ingredients & Substitutions
Sweetened Condensed Milk
You will need 1 can (14 oz / 396g) of full-fat sweetened condensed milk to act as the foundational binder. This crucial ingredient provides the sticky, creamy base required to achieve that chewy nougat-like texture.
White Chocolate Chips
Use 16 oz (450g) of high-quality white chocolate chips to build the firm, sliceable structure of the squares. As the cocoa butter cools, it solidifies the interior into a creamy, off-white block.
Marshmallow Creme (Fluff)
Measure out 7 oz (198g) of marshmallow creme to inject that signature dense chewiness. The fluff lightens the heavy chocolate slightly while ensuring the center remains soft and unbaked.
Unsalted Butter
Incorporate 3 tbsp (42g) of unsalted butter to add a silky mouthfeel and prevent the chocolate from seizing. This invisible ingredient guarantees the squares melt smoothly on the tongue.
White Coconut Rum
Add 2 tbsp (30ml) of your favorite white coconut rum (like Malibu) for an authentic tropical warmth. The clear liquid ensures the nougat base remains perfectly off-white.
Coconut Extract
Stir in 1 tsp (5ml) of coconut extract to amplify the island aroma. This concentrated flavor ensures the coconut profile shines through the rich white chocolate and marshmallow.
Fine Sea Salt
Sprinkle in 0.5 tsp (2.5g) of fine sea salt to temper the intense sweetness of the condensed milk. This foundational seasoning awakens the rum and coconut notes.
Dry White Shredded Coconut
You will need 2 cups (160g) of unsweetened, dry white shredded coconut flakes for the exterior. This coating is essential to achieve the thick, fluffy, fresh snow aesthetic described in the recipe blueprint.
Equipment Needed
- 8×8-inch (20x20cm) square baking pan
- Parchment paper (for easy removal)
- Large microwave-safe bowl or double boiler
- Silicone spatula
- Large, sharp chef’s knife
Step-by-Step Instructions
1. Prepare the Setting Pan
Line an 8×8-inch (20x20cm) square baking pan with a sheet of parchment paper. Leave a slight overhang on the edges so you can easily lift the dense nougat block out later. Set the pan aside in a cool spot.
2. Melt the Foundation
In a large double boiler over gently simmering water, combine the sweetened condensed milk, white chocolate chips, and unsalted butter. Stir continuously with a silicone spatula. Watch as the ingredients slowly melt together into a glossy, thick, off-white liquid.
3. Fold in the Nougat Base
Remove the bowl from the heat once completely smooth. Immediately dollop the marshmallow creme into the hot mixture. Fold vigorously until the fluff fully dissolves, creating a thick, sticky, unbaked nougat-like paste.
4. Infuse the Flavor
Pour the white coconut rum, coconut extract, and fine sea salt into the warm batter. Stir gently to incorporate the liquids. You will immediately smell the sweet, toasted aroma of tropical rum blending with creamy vanilla and coconut.
5. Pour and Chill
Scrape the dense mixture into your prepared baking pan, using the spatula to smooth the top into an even, flat layer. Place the pan in the refrigerator. Chill for at least 4 hours, or until the off-white block is completely firm to the touch.
6. Slice into Squares
Lift the solidified block out of the pan using the parchment paper overhang and place it on a cutting board. Run a large chef’s knife under hot water, wipe it dry, and press down firmly to slice the block. Cut neat 2-inch (5cm) square pieces, wiping the blade between cuts for precision.
7. Coat in the “Snow”
Pour the dry white shredded coconut flakes into a shallow bowl. Take each sticky square and roll it generously in the flakes. Press the dry coconut into all sides until the squares are completely enveloped and resemble freshly fallen snow.
Expert Tips for Success
- Use High-Quality Chocolate: Cheap white chocolate chips contain fillers that resist melting. Look for brands containing real cocoa butter for a perfectly creamy, off-white interior.
- Hot Knife Technique: Slicing dense, chewy nougat can be tricky. A hot, dry blade glides through the chocolate and marshmallow mixture, guaranteeing those neat 2-inch edges.
- Avoid Overheating: If using a microwave instead of a double boiler, heat in 15-second bursts at 50% power. Overheated white chocolate will seize and turn grainy, ruining the unbaked texture.
- Press the Coating: Don’t just toss the squares in the coconut. Actively press the fluffy, dry white shredded coconut into the tacky sides of the nougat so it adheres thickly.
- Keep Them Chilled: Because these are a no-bake dessert relying on butter and chocolate for structure, they soften slightly at room temperature. Keep them cold for the cleanest bite.
Storage & Reheating/Freezing
Store your finished Coconut Rum Snow Squares in an airtight container in the refrigerator for up to two weeks. Separate the layers with wax paper to prevent the fluffy coconut coating from sticking together or becoming mashed.
For longer storage, these dense squares freeze beautifully. Wrap each 2-inch piece tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. Let them thaw in the refrigerator overnight before serving to maintain their perfectly chewy, nougat-like texture.
What to Serve With This
These tropical yet wintry bars are the perfect conclusion to an elegant meal or a festive dessert spread. If you are curating a dessert table, contrast these snowy squares with the vibrant, fruity layers of our raspberry coconut magic bars or the rich, decadent cocoa notes of our white chocolate raspberry fudge.

Frequently Asked Questions
You can, but dry, unsweetened desiccated or shredded coconut works best. It provides a fluffier, ‘fresh snow’ visual aesthetic and balances the intense sweetness of the marshmallow and condensed milk interior.
No! While 2 tablespoons of white coconut rum add authentic tropical flavor without compromising the firm texture, you can substitute it with an extra teaspoon of rum extract and a splash of milk.
Yes. Because these are a no-bake dessert held together by white chocolate and butter, they will soften slightly at room temperature. Keeping them chilled maintains their dense, chewy texture.
The secret is chilling the block completely (at least 4 hours) and using a hot, dry chef’s knife. Run your blade under very hot water, wipe it completely dry, and press straight down. Repeat for every cut.
This happens if the white chocolate gets too hot during the melting process. Always use a double boiler over low, simmering water, or microwave in short 15-second intervals at 50% power to ensure smooth, creamy integration.
