Step-by-Step Instructions

Make the Custard

2. Mix sugar & cornstarch: In a bowl, whisk sugar, cornstarch, and egg yolks until smooth.
3. Combine: Slowly pour warm milk into the egg mixture, whisking continuously.
4. Cook the custard: Return to saucepan and cook on low heat until thick, stirring constantly.
5. Add vanilla: Stir in vanilla and milk powder.
6. Chill: Transfer custard to a bowl, cover with plastic wrap touching the surface, and chill.

Make the Dough

7. Activate yeast: Mix warm milk, warm water, and yeast. Let sit 5 minutes.
8. Combine dry ingredients: Mix flour, sugar, salt, and milk powder.
9. Add wet ingredients: Add yeast mixture and egg, then mix to form dough.
10. Knead: Add softened butter and knead until smooth and elastic.
11. First rise: Cover and let rise 1 hour until doubled.

Shape the Buns

12. Divide dough: Punch down and divide into 10 equal balls.
13. Fill: Flatten each dough ball, add 1 tablespoon chilled custard, and pinch edges to seal.
14. Shape: Roll gently into smooth balls.
15. Second rise: Place on baking sheet, cover, and rise 20–30 minutes.

Bake

17. Egg wash: Mix egg and water, brush over buns.
18. Bake: Cook 15–18 minutes until golden.

Helpful Cooking Tips

• Chill custard well so it’s thick and easy to shape.
• Seal buns tightly to avoid leaking.
• Knead dough until stretchy—soft dough equals fluffy buns.
• Use warm, not hot, liquids to activate yeast.
• Let buns cool a bit before eating so the filling sets.

Ingredient Substitutions & Dietary Options

• Milk powder: Optional, but adds richness.
• Butter: Coconut oil works for a lighter dairy-free option.
• Milk: Use almond or oat milk for the custard.
• Sugar: Swap with brown sugar for a deeper flavor.
• Filling: Add coconut, lemon zest, or a bit of cream cheese for variations.

Common Mistakes to Avoid

• Overheating the custard: Cook on low to avoid curdling.
• Dry dough: Add a splash of milk if dough seems stiff.
• Under-kneading: Leads to dense buns.
• Skipping the second rise: Buns won’t be fluffy.

Serving Suggestions

Serve warm with:

• Hot tea or milk tea
• Fresh fruit
• A drizzle of honey

They’re great for breakfast, brunch, or snacking.

Storage & Reheating Tips

• Room Temperature: Keeps 2 days.
• Refrigerator: Lasts 4–5 days.
• Freezer: Freeze unfilled dough balls or fully baked buns.
• Reheat: Microwave 10–12 seconds to soften.
