Let me tell you about the day I discovered these incredible coconut custard buns at a tiny bakery in Chinatown. I was wandering around after a disappointing brunch (you know how it is when the food just doesn’t hit right), and the sweet aroma of fresh bread and coconut pulled me right into this unassuming little shop. One bite of their pillowy-soft bun filled with silky coconut custard, and I was absolutely hooked! I spent the next three months perfecting this recipe because I simply couldn’t live without them.
These coconut custard buns are pure magic – imagine the softest, most tender bread you’ve ever tasted, cradling a luscious coconut custard that’s neither too sweet nor too rich. They’re like little clouds of happiness that melt in your mouth. What makes them truly special is the balance between the slightly sweet, yeasted dough and that creamy coconut filling that oozes just a tiny bit when you take that first bite. Trust me, once you make these, your kitchen will smell like a tropical paradise!

What Makes These Coconut Custard Buns So Special?
These aren’t your average dinner rolls, my friend! Coconut custard buns combine the best of both worlds – the satisfying chewiness of fresh bread with the indulgent creaminess of homemade custard. What sets this recipe apart is the technique we use to create that signature soft, almost cake-like texture in the bread. We’re using a tangzhong method (a flour and water roux) that keeps the buns incredibly moist for days.
The custard filling is where the real magic happens. Made with real coconut milk and a touch of vanilla, it’s silky smooth and has that perfect coconut flavor that’s not overwhelming – it’s like a gentle tropical breeze in your mouth. This recipe strikes the perfect balance between sweet and subtle.
Difficulty Level: Intermediate (but totally doable!)
Active Time: 45 minutes
Total Time: 4 hours (including rising time)
Serves: 12 beautiful buns
Ingredients
For the Tangzhong (Bread Softener):
- 3 tablespoons bread flour
- 1/2 cup whole milk
For the Dough:
- 2 1/4 teaspoons active dry yeast
- 1/4 cup warm water
- 2 3/4 cups bread flour
- 1/4 cup granulated sugar
- 1 teaspoon salt
- 1 large egg, room temperature
- 1/2 cup whole milk, warmed
- 3 tablespoons unsalted butter, softened
For the Coconut Custard Filling:
- 1 can (14 oz) full-fat coconut milk
- 1/3 cup granulated sugar
- 3 large egg yolks
- 3 tablespoons cornstarch
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter
For Assembly:
- 1 egg, beaten (for egg wash)
- 2 tablespoons sesame seeds (optional)
Pro tip: Make sure all your dairy ingredients are at room temperature – this helps everything come together smoothly and creates that perfect, tender texture we’re after!
Cooking Method
Step 1: Create the Tangzhong (5 minutes)
In a small saucepan, whisk together the flour and milk until completely smooth. Cook over medium-low heat, stirring constantly, until it thickens into a paste-like consistency – about 2-3 minutes. You’ll know it’s ready when you can draw lines in it with your spoon. Set aside to cool completely.
This little technique is a game-changer! The tangzhong creates an incredibly soft, bakery-style texture that stays fresh for days. Don’t skip this step – it’s what makes these buns absolutely irresistible.
Step 2: Make the Coconut Custard (15 minutes)
Here’s where the magic happens! In a medium saucepan, whisk together the coconut milk, sugar, egg yolks, cornstarch, and salt until completely smooth. Pro tip: Really whisk vigorously here – you want zero lumps!
Place over medium heat and cook, stirring constantly with a whisk, until the mixture thickens beautifully – about 8-10 minutes. It should coat the back of a spoon and hold its shape when you lift the whisk. Remove from heat and stir in vanilla and butter until melted and glossy.
Press plastic wrap directly onto the surface (this prevents that annoying skin from forming) and refrigerate until completely cool. Trust me, patience here pays off with the silkiest custard you’ve ever tasted!
Step 3: Prepare the Dough (20 minutes + rising time)
In a small bowl, dissolve the yeast in warm water and let it foam for about 5 minutes. If it doesn’t foam, your yeast might be dead – start over with fresh yeast. We want those buns to be perfectly fluffy!
In a large mixing bowl, combine flour, sugar, and salt. Add the foamy yeast mixture, egg, warm milk, and your cooled tangzhong. Mix until a shaggy dough forms, then add the softened butter.
Now comes the fun part – kneading! Turn the dough onto a lightly floured surface and knead for about 8-10 minutes until it’s smooth, elastic, and slightly tacky. The dough should spring back when you poke it gently. Don’t worry if it seems a bit sticky at first – that’s normal with this enriched dough.
Place in a greased bowl, cover with a damp towel, and let rise in a warm spot for 1-2 hours until doubled in size. Pro tip: I like to turn my oven to the lowest setting for just 1 minute, then turn it off and use it as a proofing box!
Step 4: Shape and Fill the Buns (15 minutes)
This is where things get exciting! Punch down the risen dough and turn it onto a lightly floured surface. Divide into 12 equal pieces – I use a kitchen scale for this because consistency is key.
Roll each piece into a 4-inch circle. Place about 2 tablespoons of the chilled coconut custard in the center, then gather the edges and pinch tightly to seal. Here’s the secret: Make sure those seams are really well-sealed, or your custard will leak out during baking (learned this the hard way!).
Place the buns seam-side down on parchment-lined baking sheets, leaving space between each one. Cover with a clean kitchen towel and let rise for another 45 minutes until puffy and almost doubled.
Step 5: The Grand Finale – Baking! (18-20 minutes)
Preheat your oven to 350°F (175°C). Brush the tops gently with beaten egg and sprinkle with sesame seeds if using. The egg wash gives them that beautiful golden, bakery-perfect shine.
Bake for 18-20 minutes until the tops are golden brown and the buns sound hollow when tapped. Don’t overbake – we want them tender and soft! Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
The hardest part? Waiting for them to cool enough to eat without burning your tongue. Trust me, the anticipation is worth it!
Chef’s Tips & Variations
Storage secrets: These buns are best enjoyed fresh, but they’ll keep at room temperature for 2 days in an airtight container. For longer storage, freeze them individually wrapped for up to 3 months. Just thaw at room temperature and warm gently in a 300°F oven for 5 minutes to refresh.
Flavor variations to try:
- Chocolate lovers: Add 2 tablespoons of cocoa powder to the custard for a chocolate-coconut version
- Tropical twist: Fold in some finely chopped toasted coconut to the custard for extra texture
- Citrus pop: Add the zest of one lime to the custard for a bright, tropical flavor
Make-ahead magic: You can prepare these buns up to the second rise, then cover and refrigerate overnight. Just bring to room temperature and bake as directed – perfect for weekend breakfast guests!
Troubleshooting tips: If your custard seems too thick, whisk in a tablespoon of milk. Too thin? Cook it a bit longer, stirring constantly. The perfect consistency should coat a spoon but still be pipeable.
Pairing suggestions: These are incredible with a cup of strong coffee or chai tea. For a special occasion, try them alongside fresh fruit or a light green salad for an elegant brunch spread.
