If you've ever wandered through a Thai market or bakery, you've probably noticed that distinctive bright green spread on toast and pastries. That's sangkaya bai toey (สังขยาใบเตย) — Thai pandan custard — and it's about to become your new breakfast obsession.

The best part? This luxuriously smooth spread takes less than 15 minutes of active cooking time and uses just a handful of ingredients you can find at any Asian grocery store.

Why This Recipe Is So Easy

Unlike traditional custards that require careful water baths and oven timing, Thai pandan custard is made entirely on the stovetop. You simply whisk, heat, and stir. There's no tempering eggs, no fear of curdling, and no complicated techniques. The tapioca starch does most of the work for you, creating that signature silky texture that's thicker than regular custard but spreadable like the finest European curd.

Even better, this custard is incredibly forgiving. Miss the exact moment of perfect thickness? Keep stirring for another minute. Your custard will still turn out beautifully smooth and creamy.

What to Serve with Pandan Custard

Pandan custard is the ultimate multi-purpose spread. Here are the most popular pairings:

With Bread and Toast:

• Slather it on warm Pandan Bread for a double-pandan experience
• Spread over crispy Thai Toast (Khanom Pang Ping) with condensed milk
• Use as a filling for grilled cheese sandwiches with coconut flakes

With Traditional Thai Sweets:

• Drizzle over Thai Sticky Rice with Mango for an extra layer of richness
• Serve alongside Khanom Buang (Thai crispy pancakes)
• Fill Thai Coconut Pancakes (Khanom Krok)
• Pair with Pandan Chiffon Cake or Pandan Swiss Roll

Creative Modern Uses:

• Swirl into yogurt or oatmeal
• Layer in parfaits with fresh tropical fruit
• Use as a filling for crepes or croissants
• Spread between cake layers

Ingredients

For the Pandan Extract:

• 6-8 fresh pandan leaves (or 2 teaspoons pandan extract/paste)
• 3 tablespoons water

For the Custard:

• 4 large eggs
• 1 cup (200g) granulated sugar
• 1 cup (240ml) coconut milk (full-fat, well-stirred)
• 2 tablespoons tapioca starch (or cornstarch)
• ¼ teaspoon salt
• 1 tablespoon unsalted butter (optional, for extra richness)

Step-by-Step Instructions

Step 1: Make Fresh Pandan Extract (5 minutes)

Cut pandan leaves into 1-inch pieces. Blend with 3 tablespoons wa

until completely pulverized. Strain through a fine-mesh sieve or cheesecloth, pressing firmly to extract all the bright green liquid. You should get about 2-3 tablespoons of extract. Discard the pulp.

If using pandan extract/paste, skip this step.

Step 2: Mix the Base (2 minutes)

In a medium saucepan, whisk together eggs and sugar until the sugar begins to dissolve. Add coconut milk, tapioca starch, salt, and pandan extract. Whisk vigorously until completely smooth with no lumps of starch visible.

Step 3: Cook the Custard (8-10 minutes)

Place the saucepan over medium-low heat. Stir continuously with a silicone spatula or wooden spoon, making sure to scrape the bottom and corners of the pan. The mixture will remain thin for the first 5-6 minutes — don't worry, this is normal.

Around the 6-7 minute mark, you'll notice the custard beginning to thicken. Keep stirring steadily. The custard is done when it coats the back of your spoon and slowly drips off in thick ribbons. It should look glossy and jiggle slightly when you shake the pan.

Step 4: Finish and Cool

Remove from heat immediately. Stir in the butter if using (this adds shine and extra silkiness). Transfer to a heat-proof container or jar. Place plastic wrap directly on the surface of the custard to prevent a skin from forming.

Let cool to room temperature, then refrigerate for at least 2 hours before serving. The custard will thicken further as it cools.

Common Problems and Solutions

Problem: Custard is too runny

• Solution: Return to the stove and cook for 2-3 more minutes while stirring. The tapioca starch needs enough heat to fully activate.

Problem: Lumps formed in the custard

• Solution: Strain the custard through a fine-mesh sieve while still hot. Press through with a spatula to remove any cooked egg bits.

Problem: Custard is separated or looks grainy

• Solution: The heat was too high. Use an immersion blender to re-emulsify, or strain and whisk vigorously while still warm.

Problem: Color isn't bright green

• Solution: Use fresh pandan leaves for the most vibrant color, or add 1-2 drops of green food coloring if using pandan extract.

Problem: Custard formed a thick skin on top

• Solution: Always press plastic wrap directly onto the surface while cooling. If a skin has already formed, simply peel it off before serving.

Essential Equipment 

• Medium Saucepan (2-3 quart) — Look for a heavy-bottom stainless steel for even heating
• Silicone Spatula — Heat-resistant and perfect for scraping corners
• Fine-Mesh Strainer — For straining pandan leaves and removing any lumps
• Whisk — A balloon whisk works best for initial mixing
• Glass Jars with Lids (8 oz or 16 oz) — For storage, preferably with airtight seals
• Blender — Any standard blender works for processing pandan leaves

Insider Tips You Won't Find in Regular Recipes

The Restaurant Secret: Professional Thai kitchens add 1 tablespoon of sweetened condensed milk to their pandan custard. This creates an extra creamy texture and adds subtle caramel notes that complement the pandan beautifully.

For Maximum Pandan Flavor: Freeze your fresh pandan leaves for 2 hours before blending. Freezing breaks down the cell walls, releasing more aromatic compounds and giving you a much more intense flavor and brighter green color.

The Texture Hack: Mix tapioca starch and cornstarch half-and-half (1 tablespoon each) instead of using just one. Tapioca gives glossy smoothness while cornstarch provides stability. This combination creates a custard that spreads perfectly even straight from the fridge.

Avoid the Eggy Taste: Add ½ teaspoon of vanilla extract along with the pandan. This neutralizes any potential egg smell without interfering with the pandan flavor.

Storage Trick: Pour a thin layer of coconut cream (about 1 tablespoon) over the surface of your custard before sealing. This creates a protective barrier and keeps the custard incredibly moist for up to 2 weeks in the fridge.

The Professional Finish: After cooking, pass your custard through a fine-mesh strainer even if it looks perfectly smooth. This extra step removes any microscopic bits and creates that ultra-silky, professional texture.

Color Preservation: Add a tiny pinch of baking soda (literally just a few granules) to your pandan extract before adding it to the eggs. This keeps the green color vibrant for days and prevents it from turning dull olive.

Storage: Keep refrigerated in an airtight container for up to 1 week. The custard thickens as it sits, which is completely normal. For a softer, more spreadable consistency, let it sit at room temperature for 10 minutes before serving.

Make-Ahead: This custard actually tastes better the next day as the flavors meld together. Make it 1-2 days in advance of serving for optimal flavor.

Now you're ready to create this beloved Thai treat in your own kitchen. The aroma of pandan will fill your home, and you'll have a versatile spread that transforms ordinary breakfasts into something special. Once you taste this fragrant, creamy custard, you'll understand why it's been a Thai favorite for generations.
