Ingredients

For the Custard Base

• 2 cups ripe mango puree
• 1 can (13.5 oz) full-fat coconut milk
• 4 large eggs
• ¾ cup granulated sugar
• ½ cup rice flour
• ¼ cup all-purpose flour
• 1 teaspoon vanilla extract
• ¼ teaspoon salt

For Texture and Flavor

• ½ cup finely shredded unsweetened coconut
• 1 tablespoon lime zest
• 1 tablespoon fresh lime juice

Optional Garnish

• Toasted coconut flakes
• Fresh mango cubes
• Lime zest curls
• Mint leaves

Instructions

1. Prepare the Baking Dish

Lightly grease an 8-inch square baking dish and line it with parchment paper, allowing some overhang on the sides for easy removal later.

2. Preheat the Oven

Preheat your oven to 350°F (175°C). Allow it to fully heat while preparing the custard mixture.

3. Make the Mango Puree

Peel and chop ripe mangoes. Blend until completely smooth. Measure out exactly two cups of puree for consistent texture.

4. Combine Wet Ingredients

In a large mixing bowl, whisk together:

• Mango puree
• Coconut milk
• Eggs
• Vanilla extract
• Lime juice

Whisk until smooth and evenly combined.

5. Add Dry Ingredients

Gradually add:

• Sugar
• Rice flour
• All-purpose flour
• Salt

Whisk continuously to prevent lumps from forming.

6. Incorporate Coconut

Fold in the shredded coconut and lime zest. These ingredients add texture and enhance the tropical flavor profile.

7. Fill the Baking Dish

Pour the custard mixture into the prepared baking dish. Tap gently on the counter to release trapped air bubbles.

8. Bake

Place the dish on the center rack and bake for 40–45 minutes.

The edges should appear set while the center remains slightly soft but no longer liquid.

9. Cool Completely

Allow the custard to cool at room temperature for about 45 minutes before transferring to the refrigerator.

10. Chill

Refrigerate for at least 3 hours, preferably overnight. This step helps the custard firm up and develop clean slicing texture.

11. Slice and Serve

Lift the chilled custard from the pan using the parchment paper. Cut into squares using a sharp knife wiped clean between cuts.

12. Garnish

Top with toasted coconut flakes, fresh mango cubes, or lime zest immediately before serving.

Pro Tips

Choose Extra-Ripe Mangoes

The sweeter and more fragrant the mangoes, the better the final dessert. Look for fruit that yields slightly when gently pressed.

Use Full-Fat Coconut Milk

Light coconut milk won’t create the same luxurious texture. Full-fat versions provide richness and stability.

Chill Overnight

Although three hours is sufficient, overnight chilling dramatically improves flavor and texture.

Strain for Ultra-Smooth Custard

For bakery-quality results, strain the batter through a fine mesh sieve before baking.

Toast the Coconut Garnish

A few minutes in a dry skillet creates deeper flavor and beautiful contrast against the creamy custard.

Variations

1. Mango Sticky Rice Custard Squares

Add cooked sweet sticky rice to the bottom of the baking dish before pouring in the custard mixture. This creates a dessert inspired by Thailand’s famous mango sticky rice.

2. Pineapple Coconut Custard Squares

Replace half of the mango puree with pineapple puree for a brighter tropical flavor.

3. Passion Fruit Mango Bars

Swirl passion fruit pulp into the batter before baking for a tart and aromatic twist.

4. Coconut Chocolate Tropical Squares

Add a thin layer of melted dark chocolate beneath the custard for a richer dessert.

5. Gluten-Free Version

Replace the all-purpose flour with additional rice flour to make the recipe fully gluten-free.

Storage & Reheating

Refrigerator

Store in an airtight container for up to 5 days. The flavor actually improves after the first day as the ingredients meld together.

Freezer

Freeze individual squares for up to 2 months. Wrap each square tightly before storing.

Thawing

Transfer frozen squares to the refrigerator overnight before serving.

Reheating

These custard squares are best enjoyed chilled. Reheating is not recommended because it can alter the creamy texture.

Common Mistakes to Avoid

Using Under-Ripe Mangoes

Firm, sour mangoes create a less flavorful dessert. Fully ripe fruit is essential.

Skipping the Chill Time

Cutting too early results in messy slices and softer texture.

Overbaking

Custard continues setting as it cools. Remove it once the center is mostly set.

Using Low-Fat Coconut Milk

Reduced-fat products can create a thinner, less satisfying custard.

Not Lining the Pan

Parchment paper makes removal significantly easier and helps maintain clean edges.

Overmixing

Excessive whisking can introduce too much air, creating an uneven texture after baking.

Cultural Context or Fun Facts

Mangoes hold a special place throughout Southeast Asia and are particularly beloved in Thailand. One of the country’s most iconic desserts combines ripe mango with sweet coconut sticky rice, showcasing the region’s appreciation for balancing fruit sweetness with creamy coconut richness.

Coconut milk appears in countless Thai dishes, both savory and sweet. Its naturally rich texture makes it ideal for custards, puddings, and desserts. The inspiration behind these custard squares comes from those classic flavor combinations while adapting them into a convenient, sliceable dessert suitable for modern home kitchens.

Interestingly, mangoes are one of the world’s most consumed fruits, with hundreds of varieties grown globally. Different mango cultivars contribute unique aromas ranging from floral and honey-like to citrusy and tropical.
