Ingredient Lowdown

• Graham cracker crumbs: This gives the crust its classic, toasty crunch—feel free to use digestive biscuits if you want a touch less sweetness.
• Sweetened shredded coconut: Twice featured—in crust and filling—this adds real coconut depth and chewiness.
• Brown sugar: Adds warmth and a subtle molasses note to the crust.
• Unsalted butter: Melted to bind the crust into a buttery base that crisps beautifully.
• Sweetened condensed milk: The heart of the filling, it brings sweetness and that irresistibly creamy texture.
• Full-fat coconut milk: Boosts coconut flavor and lends richness to the filling.
• White or dark rum: Adds a fragrant boozy warmth—you’ll find Malibu works beautifully for a coconut punch, but you can swap to any rum you love.
• Cornstarch: Key for thickening the filling into that luscious, sliceable custard you want.
• Salt: Just a pinch to balance and elevate all the sweet notes.
• Whole milk: Smooths out the filling and keeps it from getting too dense.
• Vanilla extract: A touch of fragrant sweetness that rounds out the flavors.
• Butter (softened): Added to the filling for a richness and shiny finish.
• Coconut flakes: Toasted lightly and sprinkled on top for a crisp, nutty contrast and that classic snow-like look.

Set Up for Success

Mise en place is your best friend here. Measure out everything before starting so when you whisk the filling it’s smooth sailing without scrambling to find ingredients. Line your 8×8-inch pan carefully with parchment paper, letting some edges hang over the sides for easy lifting after chilling. This simple prep will save you frustration and keep those layers clean and sharp.

Step-by-Step: Coconut Rum Snow Squares Recipe

1. Prepare the crust: Combine graham cracker crumbs, shredded coconut, and brown sugar in a bowl. Pour in the melted butter, mixing until everything’s evenly moistened—the base should press together firmly but not be greasy. Press this golden, fragrant mixture firmly into the bottom of your parchment-lined 8×8-inch pan. Pop it into the fridge while you get the filling going.
2. Cook the filling: Start by whisking together cornstarch, salt, and whole milk in a medium saucepan until fully dissolved—that’s key to avoiding lumps. Set this over medium heat and add the sweetened condensed milk and coconut milk, whisking constantly. You’ll notice the mixture thicken nicely after about 5 minutes and start to bubble gently—that’s your cue to reduce the heat. Stir in vanilla, shredded coconut, and softened butter until the filling is silky and thick.

Chef’s Notes & Success Tips
Keep whisking the filling gently once it starts bubbling to prevent sticking or lumps. The texture should be thick enough to hold its shape when you run your finger through it—like a soft pudding. Adding the rum at the end preserves its fragrant notes without boiling off that essential warmth.
3. Finish the filling: Remove the pan from heat and stir in the rum until smoothly combined. The aroma at this point is utterly inviting, with that coconut and rum bouquet filling your kitchen.
4. Assemble and chill: Pour the warm filling over your chilled crust. Use a spatula to spread the layer evenly—this is where you seal all those lovely textures together. Let the pan rest at room temperature for about 20 minutes; this helps prevent condensation and ensures a silky set. Then cover and refrigerate for at least 4 hours or overnight until fully firm.
5. Garnish and slice: Just before serving, sprinkle the lightly toasted coconut flakes evenly on top. They add a crisp, nutty contrast that’s as beautiful as it is tasty. Use a sharp knife, cleaned between cuts, to slice into 16 neat squares. This keeps the edges clean and your presentation crisp.

Flavor Twists for Coconut Rum Snow Squares Recipe

• Citrus boost: Add a teaspoon of lime zest to the filling for a bright, tangy lift that pairs beautifully with the coconut and rum.
• Spiced rum option: Swap white rum for spiced rum to bring in warm cinnamon and clove notes that deepen the flavor profile.
• Tropical mix-ins: Fold in finely chopped pineapple or mango pieces into the filling for exciting fruity texture bursts.
• Nutty crunch: Sprinkle chopped toasted macadamia nuts on top along with the coconut flakes for extra crunch and richness.
• Chocolate drizzle: After cooling, drizzle melted dark or white chocolate on top for a decadent touch your guests will swoon over.

Storage & Make-Ahead Tips

• Refrigerate: Store the finished squares in an airtight container in the fridge for up to 4 days. They actually taste better as the flavors meld!
• Freeze: Wrap individual squares tightly in plastic wrap and place in a freezer-safe container. Freeze up to 2 months. Thaw overnight in the fridge.
• Serve chilled: These sweets shine best served cold, so slice them before chilling for the evening’s dessert.
• Prep ahead: You can make the crust and filling a day ahead, then assemble and chill final on serving day for a stress-free sweet finish.

Coconut Rum Snow Squares Recipe FAQs

• Can I use light coconut milk instead of full-fat? You can, but full-fat coconut milk gives a richer, creamier filling that’s key to those lush squares.
• Is it possible to make this recipe without alcohol? Absolutely! Simply omit the rum and increase vanilla by a little to keep the flavor layered.
• Why do I need to chill the crust before adding filling? Chilling helps set the crust firmly, preventing it from becoming soggy once the filling is poured on.
• What if my filling is lumpy? Make sure to whisk the cornstarch thoroughly in milk before heating to avoid lumps. If lumps appear, strain through a fine mesh before adding to the pan.
• How should I toast the coconut flakes? Toast them in a dry skillet over medium heat, stirring frequently, until golden and fragrant—usually 2-4 minutes.
