Thai Egg Cake Recipe: Silky Coconut Mousse With Toasted Pandan Crunch

This Thai egg cake recipe delivers the delicate balance of silky coconut mousse and toasted pandan crunch that makes it a festival favorite. The secret lies in the whipped egg whites that create an airy, jiggly texture while the coconut milk adds natural sweetness and richness.

I first discovered this recipe during a Thai New Year celebration, where it was served as a ceremonial dessert—light enough to feel elegant but rich enough to satisfy any sweet tooth.

The magic happens in the baking process: a low oven temperature ensures the cake rises gently, while the pandan-infused coconut topping adds an aromatic crunch that contrasts beautifully with the soft interior.

This recipe uses simple ingredients—eggs, coconut milk, sugar, and pandan extract—but the technique transforms them into something truly special. The result is a dessert that’s both visually stunning and impossibly tender.

What makes this Thai egg cake truly unique is its versatility. While traditionally baked, it can also be steamed for a lighter texture, and the pandan flavor can be adjusted to suit your taste.

The coconut mousse layer is creamy yet light, while the toasted pandan topping adds a subtle nutty depth that elevates every bite. Perfect for celebrations or as a decadent treat, this recipe is sure to impress.

Whether you're serving it at a gathering or simply indulging in a moment of self-care, this Thai egg cake brings a taste of tradition to your table. The process is straightforward, but the result is anything but ordinary—restaurant-quality dessert made in your own kitchen. Let’s get started!

Ingredients for thai egg cake

Eggs, coconut milk, and pandan extract transform into this elegant Thai dessert.

The coconut milk is non-negotiable here—full-fat canned versions like Thai Kitchen or Aroy-D give the richest flavor. Store-bought pandan extract works, but for authenticity, hunt down pure extract at Asian markets or online. The eggs must be room temperature; cold eggs won't whip properly. For the coconut topping, lightly toast the flakes in a dry pan until golden—this adds that essential crunch. If you can't find pure pandan extract, pandan paste diluted with water works in a pinch, though it may be slightly thicker.

No pandan extract? Vanilla bean paste at double the amount gives a milder floral note, though it won't replicate that signature pandan aroma. Substituting coconut milk? Full-fat canned coconut cream works in a bind, but it's thicker—adjust other liquids accordingly. For the eggs, if you're concerned about salmonella, use pasteurized eggs or pasteurize your own by heating to 160°F. The cornstarch is key for the mousse texture—don't skip it, even if you're tempted to cut calories. For a gluten-free version, swap the all-purpose flour for rice flour or gluten-free 1:1 blend.

This cake keeps beautifully—covered at room temperature for 2 days or fridge for 5 days. The mousse layer stays fresh remarkably well, though the toasted coconut topping may lose some crunch. For serving, dust with extra shredded coconut or a light layer of powdered sugar. Freeze portions of the mousse layer separately for up to 3 months—thaw overnight in the fridge before assembling. The batter can be prepped ahead and refrigerated for up to 12 hours before baking, making this a great make-ahead dessert.

Step-by-step instructions for Thai egg cake

This delicate Thai dessert transforms simple ingredients into a silky coconut mousse with a signature pandan crunch.

Begin by separating the 8 whole large eggs, placing yolks in a heatproof bowl and whites in a clean, grease-free container. I like to use a fine-mesh strainer for this to catch any stray bits of white that might fall through. Over a double boiler, gently whisk the yolks with the 1.5 cups granulated sugar until the mixture reaches 160°F and thickens into a pale, ribbon-like consistency.

The sugar should dissolve completely, and when you lift the whisk, the ribbon should hold its shape for a moment before melting back into the mixture. This process, called tempering, ensures a smooth, glossy texture without graininess. Remove from heat immediately once it reaches temperature—overheating will cause the yolks to scramble.

In a separate bowl, combine the 13.5 oz unsweetened coconut milk with the 1 tsp pandan extract, 0.5 cup all-purpose flour, 0.5 tsp baking powder, 0.25 tsp salt, 0.5 tsp vanilla extract, and 1 tbsp cornstarch. Whisk until fully dissolved and smooth—this creates the base for our mousse. Slowly pour this mixture into the warm yolk-sugar blend while whisking constantly to prevent curdling.

Real talk: The pandan extract is where the magic happens. It gives that signature floral aroma and vibrant green hue. If you can't find pure pandan extract, a drop of green food coloring will mimic the color, though it won't capture the full flavor. The cornstarch here acts as a stabilizer to prevent the mousse from deflating later.

In the clean, grease-free container, beat the egg whites to stiff peaks using a stand mixer or hand whisk. You'll know they're ready when they hold their shape and leave a slight trail when the whisk is lifted. Gently fold one-third of the whites into the yolk mixture to lighten it, then carefully fold in the remaining whites until just combined.

This is where patience pays off. Overmixing now will incorporate too much air and cause the cake to collapse later. Fold just until no white streaks remain—think of it like gently combining two delicate clouds. The batter should be smooth, glossy, and hold its shape when spooned, though it may still ripple slightly.

In a separate bowl, melt the 4 tbsp unsaltened butter and mix with the 1 cup toasted coconut flakes and 0.5 cup shredded coconut. Press this mixture firmly into the bottom of an 8-inch springform pan, creating an even layer. Chill in the refrigerator while you prepare the filling—this creates the signature crunchy base that contrasts with the silky mousse.

Don't skip this chilling step. A warm crust will melt into the mousse, losing that essential texture contrast. The toasted coconut flakes should be lightly golden—not burnt—and the shredded coconut should be evenly distributed. This layer isn't just for texture; it adds depth of flavor that carries through the entire dessert.

Pour the batter over the chilled coconut crust and smooth the top with a spatula. Bake in a 325°F oven for 45-50 minutes until the center is just set—it should still have a slight wobble when gently shaken, but the edges should be firm to the touch. Avoid overbaking, which will make the mousse dry and grainy.

When done, let the cake cool completely in the pan before releasing the springform. Then refrigerate for at least 4 hours, preferably overnight. This resting period allows the flavors to meld and the texture to fully set. The contrast between the cool, creamy mousse and the warm, toasted coconut is what makes this dessert truly special.

Best sauces and condiments for this recipe

Pandan-Coconut Syrup

This is my go-to sauce for enhancing the Thai egg cake's natural flavors. Simmer ½ cup coconut milk with 2 tbsp sugar and ½ tsp pandan extract until reduced by half.

Drizzle over slices just before serving to add a glossy, aromatic finish that complements the coconut and egg whites perfectly. 🌿

Sweet Chili Glaze

For a spicy-sweet contrast, blend ¼ cup sweet chili sauce (like Maesri brand) with 1 tbsp coconut cream until smooth. Drizzle lightly over individual slices—just enough to add a tangy kick without overpowering the delicate mousse. This works especially well if you prefer a touch of heat with your desserts.

Toasted Coconut Caramel

Elevate your presentation with a quick coconut caramel sauce. Melt ½ cup coconut sugar in a saucepan, then whisk in 2 tbsp coconut milk until smooth. Let cool slightly before drizzling over the cake.

The caramelized coconut flavor mirrors the cake's base while adding a luxurious sheen. Store-bought coconut caramel sauce (like Thai Kitchen) works in a pinch.

Lime Zest Garnish

Brighten the dessert with a zesty finish. Mix 1 tsp lime zest with 1 tbsp powdered sugar and sprinkle over the top before serving. The citrus cuts through the richness, balancing the coconut and egg flavors beautifully.

For extra flair, add a few drops of lime juice to the syrup or glaze before drizzling.

Vanilla Bean Custard

For a richer pairing, serve the egg cake alongside a light vanilla custard. Whisk 1 cup coconut milk with 2 egg yolks, 2 tbsp sugar, and ½ tsp vanilla bean paste, then strain and bake in a water bath at 325°F for 20 minutes.

The custard's creamy texture contrasts wonderfully with the cake's airy mousse.
