Ingredients You'll Need

The magic of these custard buns comes from a handful of simple yet essential ingredients. Each one plays a special role, whether it’s creating that tender dough, the rich custard filling, or the beautiful golden color that makes these buns so inviting.

• Large egg yolks: Provide richness and that characteristic golden color to the custard filling.
• Whole milk: Adds creaminess and helps achieve the perfect custard texture.
• Sugar: Sweetens the filling; you can adjust the amount based on your sweetness preference.
• Dry whole milk powder (optional): Enhances the creamy taste and gives the custard extra body.
• Cornstarch slurry: Thickens the custard to the ideal custard-like consistency without lumps.
• Active dry yeast: Essential for the dough to rise and become fluffy.
• All-purpose flour (bleached): Forms the soft and elastic dough structure.
• Chilled whole milk for the dough: Keeps the yeast happy and helps develop the dough's texture smoothly.

Directions

Step 1: Start by preparing the custard filling. In a bowl, whisk together the egg yolks, whole milk, sugar, milk powder (if using), and the cornstarch dissolved in water. Pour this mixture into a saucepot over high heat.

Step 2: Stir constantly as it heats, and watch carefully until it reaches a rolling boil. Keep boiling for 2 minutes, stirring to prevent burning, then transfer the custard to a bowl. Cover tightly and chill in the refrigerator for at least one hour; this step really helps the custard set beautifully.

Step 3: While the custard cools, prepare the dough by mixing chilled milk and yeast in a large bowl. Let it sit for a minute or two until the yeast starts to activate.

Step 4: Add the flour to the milk and yeast mixture and begin stirring with a spatula until it looks clumpy. Then, knead the dough by hand for about 15 minutes until it becomes smooth and elastic. If the dough feels sticky, sprinkle in a little more flour gradually. Cover with plastic wrap or a clean towel and let it rest for 5 minutes.

Step 5: Divide the dough evenly into 8 pieces. Take each piece and roll it into an oval. Fold the top and bottom halves into the middle, pressing lightly, and then pinch the sides to form a smooth ball.

Step 6: Flatten each dough ball into a ¼ inch thick circle and place a generous spoonful of the chilled custard in the center. Pinch the edges together firmly to seal the custard inside and gently shape into a round bun. Place each bun on prepared parchment squares with the smooth side up.

Step 7: Arrange the buns in your steamer, making sure there's enough space between them for rising. Cover with a lid and proof the buns in a warm spot for about 1 hour until they double in size.

Step 8: Once proofed, steam the buns over low heat for 10 minutes. Avoid opening the lid during steaming to keep the buns fluffy and moist. Serve immediately while warm and enjoy the beautiful custard surprise inside.

Servings and Timing

This recipe makes 8 custard buns, which I find perfect for sharing with family or enjoying over a couple of days as a special treat. Prep time is around 20 minutes for the custard and dough combined, plus 1 hour chilling time for the custard and about 1 hour proofing time for the dough. The steaming takes just 10 minutes, so all in all, you're looking at roughly 2.5 to 3 hours, but much of that is resting and proofing – perfect for a relaxed day in the kitchen.

How to Serve This Custard Buns (Nai Huang Bao, Lai Wong Bao) Recipe

I love serving these custard buns warm, fresh out of the steamer, because that’s when the custard inside is at its creamiest and the dough so soft it melts in your mouth. They make an excellent centerpiece for a dim sum brunch alongside dishes like shrimp dumplings or steamed pork ribs. If I’m feeling playful, I like to garnish the buns with a tiny dusting of powdered sugar or a few edible flower petals for a delicate touch on the plate.

When it comes to drinks, I often pair these Custard Buns (Nai Huang Bao, Lai Wong Bao) Recipe with a cup of jasmine or oolong tea, which balances the sweetness with its fragrant, slightly astringent notes. For a special occasion, a lightly sweet Riesling or sparkling wine can be surprisingly delightful. I recommend serving them in small portions – one or two buns per person – as they are quite rich, making them ideal for parties, festive gatherings, or a weekend indulgence.

If you want to impress guests, arrange each bun on a small individual plate lined with parchment and provide little bamboo steamers for a visually charming experience. They’re best eaten warm but also delightful at room temperature if you’re packing them for picnics or lunchboxes.

Variations

One of my favorite things about this Custard Buns (Nai Huang Bao, Lai Wong Bao) Recipe is how easy it is to customize. For instance, you can substitute regular granulated sugar with coconut sugar or honey for a slightly deeper sweetness and a hint of different flavor. If you prefer a vegan version, simply swap out the egg yolks and dairy milk for a plant-based milk like oat or almond and a thickener such as arrowroot starch instead of cornstarch. The texture changes slightly but still yields wonderfully soft buns.

For those with gluten sensitivities, you can experiment with gluten-free flour blends, but be mindful that the dough elasticity may alter and might require additional binding agents. Another exciting variation is adding a hint of vanilla or pandan extract to the custard filling for a fragrant twist that I personally adore.

While steaming is traditional and produces that perfect soft texture, I’ve also tried baking these buns for a golden crust outside, which gives a completely different but equally satisfying experience. Just brush the buns with a little egg wash and bake them at moderate heat for about 12-15 minutes.

Storage and Reheating

Storing Leftovers

If you have leftover custard buns, store them in an airtight container at room temperature if you plan to eat them within the same day. For longer storage, I prefer refrigerating them in a sealed container for up to 2 days. The bun may firm up a little in the fridge, but the custard retains its delightful flavor.

Freezing

You can absolutely freeze these buns to enjoy later. Place them individually on a baking sheet lined with parchment, freeze until solid, then transfer to a freezer-safe container or bag. They keep well frozen for up to 1 month. When ready to eat, thaw them overnight in the fridge and steam gently to refresh their softness.

Reheating

For the best results, avoid microwaving as it can dry the dough and curdle the custard. Instead, reheat the buns by steaming for 5-7 minutes until warmed through. This method helps restore their light texture and creamy filling without losing moisture or flavor.

FAQs

Can I make the custard filling ahead of time?

Absolutely! In fact, chilling the custard for at least an hour really improves its texture and makes it easier to work with when filling the buns. You can even prepare it a day ahead and keep it refrigerated, just make sure to cover it well to prevent a skin from forming.

What should I do if the dough is too sticky to handle?

The key is to add flour gradually, about a teaspoon at a time, while kneading until the dough feels smooth and elastic but not dry or crumbly. The exact amount can vary depending on flour brand and humidity, so hands-on feel is your best guide here.

Can I use a stand mixer instead of kneading by hand?

Definitely! Using a stand mixer with a dough hook speeds up the kneading process and reduces effort. I recommend mixing for about 10 minutes on medium speed until the dough is smooth and elastic, rather than the 15 minutes by hand.

How do I know when the buns have properly proofed?

They should roughly double in size and feel soft and puffy to the touch. Press lightly with a finger; if the indent springs back slowly, they’re ready to steam. Under-proofed buns will be dense, and over-proofed ones may collapse during steaming.

Is there a way to make the custard less sweet?

Yes, simply reduce the sugar to your taste—start with half the recommended amount and adjust from there. The custard still tastes silky and rich even when less sweet, which I often prefer personally.

Conclusion

I hope you’re as excited as I am to try this Custard Buns (Nai Huang Bao, Lai Wong Bao) Recipe in your own kitchen.
