No-Bake Vietnamese Coconut Raspberry Bars

What Makes This Special

Inspired by the dreamy coconut flavors of Vietnamese chè and the vibrant red of summer raspberries, these no-bake bars bring a burst of freshness and tropical comfort. Layered for beauty and ease, their creamy coconut custard and tart, jewel-like raspberry topping make them both a visual and flavor celebration—perfect for sunny days and those new to no-bake desserts!

Ingredients

This recipe combines classic Vietnamese coconut pudding (chè dừa) flavors with a Western bar format and a pop of summer raspberries. Digestive biscuits form a sturdy, buttery base, while coconut milk and condensed milk create a lush, sweet custard. Raspberries add brightness and color, and a hint of lime delivers a refreshing finish.

For the Coconut Biscuit Base

• Digestive biscuits: Provide a toasty, nutty crunch and soak up the butter.
• Unsalted butter: Binds the crumbs and adds rich flavor.

For the Creamy Coconut Layer

• Canned coconut milk: For authentic Vietnamese coconut flavor and creamy texture.
• Condensed milk: Adds sweetness and silky body.
• Granulated sugar: Balances out the tart raspberry layer.
• Cornstarch: The secret to the custard’s delicate set—no baking needed.
• Sea salt: Enhances all the flavors.
• Desiccated coconut: For bite, texture, and extra coconut flavor.
• Vanilla extract: Rounds out the flavors.
• Lime zest: Adds a sunny, zippy twist.

For the Raspberry Layer

• Fresh raspberries: Provide seasonal tartness, color, and freshness.

Instructions

Step 1: Prepare the Pan and Biscuit Base

• Line your 20x20 cm (8x8 inch) baking pan with parchment, leaving some overhang for easy removal later.
• Blitz the digestive biscuits in a food processor (or crush in a ziplock bag with a rolling pin) until finely ground.
• Mix crumbs with melted butter until the texture resembles wet sand.
• Press the mixture firmly and evenly into the bottom of your lined pan. Use the bottom of a glass to compact it. Pop into the fridge while you make the filling—this helps it set up nicely.

Step 2: Make the Coconut Custard Layer

• In a medium saucepan (off heat), whisk together the coconut milk, condensed milk, sugar, cornstarch, and salt until smooth.
• Place over medium heat. Cook, whisking constantly, until the mixture thickens to a pudding-like consistency (about 6–8 minutes). It should coat the back of a spoon.
• Remove from heat. Stir in the desiccated coconut, vanilla, and lime zest.
• Pour the warm coconut custard over your chilled base, smoothing the top with a spatula. Let cool for 10 minutes at room temperature, then transfer to the fridge for 1 hour to partially set.

Step 3: Add the Raspberry Layer

• While the coconut layer cools, lightly mash half the raspberries with the back of a fork (just to release some juice, don’t puree).
• After the coconut layer is partially set, gently scatter the mashed raspberries over the top, then dot with the remaining whole berries. Press them very lightly into the coconut custard.
• Sprinkle extra desiccated coconut over the top for a pretty, sunny finish.
• Chill the bars for at least 3 more hours, or until completely set and sliceable.

Step 4: Slice and Serve

• Lift the bars from the pan using the parchment overhang.
• Slice into 16 squares. Wipe your knife between cuts for tidy edges.
• Serve chilled, ideally on a warm sunny day!

Pro Tips

• Use full-fat coconut milk: For the creamiest, most stable custard; avoid low-fat or carton types.
• Chill thoroughly: The longer the bars chill, the cleaner your slices will be.
• Customize the topping: Try a mix of raspberries and mango for a Vietnamese-style tropical twist!

Troubleshooting

Problem? The custard is runny or won’t set.
Solution: Make sure you cooked the coconut mixture long enough (until thick!) and measured the cornstarch accurately.

Another issue? The base crumbles when slicing.
Solution: Pack the base very firmly and give the bars extra chill time before cutting.

Variations

• Mango Sunshine Bars: Replace half the raspberries with fresh diced mango for tropical color and sweetness.
• Lime Coconut Dream: Add extra lime zest or a drizzle of lime juice to the custard for even more zing.
• Chè Ba Màu Inspired: Layer with green pandan jelly (use store-bought or DIY) beneath the raspberries for a three-color, festive look.

Storage

Store bars in an airtight container in the fridge for up to 4 days. For the freshest taste, add the raspberry topping on the day you plan to serve. Bars do not freeze well due to the fresh fruit and creamy custard—enjoy them chilled and fresh for the best texture and flavor!
