Preparation Time

• Prep Time: 30 minutes
• Rising Time: 1 hour 45 minutes to 2 hours
• Baking Time: 18–22 minutes
• Total Time: Approximately 3 hours

Yield

• 10–12 buns

Ingredients

For the Dough

• 4 cups (500g) bread flour
• ¼ cup (50g) granulated sugar
• 2¼ teaspoons (7g) instant yeast
• 1 teaspoon salt
• 1 large egg, room temperature
• 1 cup (240ml) warm milk (about 38°C/100°F)
• ¼ cup (60ml) heavy cream
• 4 tablespoons (56g) unsalted butter, softened

For the Egg Wash

• 1 egg
• 1 tablespoon milk

For the Topping

• 2–3 tablespoons white sesame seeds
• 1 tablespoon black sesame seeds (optional)

Equipment Needed

• Large mixing bowl
• Stand mixer with dough hook (optional)
• Measuring cups and spoons
• Baking tray
• Parchment paper
• Kitchen towel or plastic wrap
• Pastry brush

Step-by-Step Directions

Step 1: Activate the Yeast

If using instant yeast, you can mix it directly with the flour. If using active dry yeast:

1. Pour the warm milk into a small bowl.
2. Add 1 teaspoon of the sugar.
3. Sprinkle the yeast over the milk.
4. Let it sit for 5–10 minutes until foamy.

A foamy surface indicates that the yeast is active and ready to use.

Step 2: Mix the Dry Ingredients

In a large mixing bowl:

1. Combine bread flour, remaining sugar, and salt.
2. Whisk together thoroughly to distribute the ingredients evenly.

Keeping the salt separate from direct contact with the yeast initially helps maintain optimal yeast activity.

Step 3: Add the Wet Ingredients

1. Add the egg to the flour mixture.
2. Pour in the warm milk and heavy cream.
3. Mix with a wooden spoon or dough hook until a shaggy dough forms.

At this stage, the dough may appear sticky and uneven. This is completely normal.

Step 4: Knead the Dough

By Stand Mixer

1. Knead on medium-low speed for about 5 minutes.
2. Add the softened butter one tablespoon at a time.
3. Continue kneading for another 8–10 minutes.

By Hand

1. Transfer the dough onto a lightly floured surface.
2. Knead for 8 minutes.
3. Gradually work in the softened butter.
4. Continue kneading for another 10–12 minutes.

The dough should become smooth, elastic, and slightly tacky but not excessively sticky.

Windowpane Test

Take a small piece of dough and gently stretch it.

If it stretches into a thin translucent sheet without tearing, the dough is properly developed.

Step 5: First Rise

1. Shape the dough into a ball.
2. Place it in a lightly greased bowl.
3. Cover with plastic wrap or a damp towel.
4. Let rise in a warm place for 60–90 minutes.

The dough should double in size.

Step 6: Divide and Shape

1. Gently punch down the risen dough to release excess air.
2. Transfer it to a clean work surface.
3. Divide into 10–12 equal portions.

To shape each bun:

1. Flatten a dough portion slightly.
2. Pull the edges toward the center.
3. Pinch the seams together.
4. Turn seam-side down.
5. Roll gently under your palm to create a smooth round ball.

This shaping method creates a beautiful bakery-style appearance.

Step 7: Arrange on the Baking Tray

1. Line a baking tray with parchment paper.
2. Place the dough balls about 2 inches apart.
3. Cover loosely with a kitchen towel.

Step 8: Second Rise

1. Allow the shaped buns to rise for 45–60 minutes.
2. They should become puffy and nearly double in size.

The second rise is crucial for achieving a light and airy texture.

Step 9: Prepare the Egg Wash

In a small bowl:

1. Beat together the egg and milk.
2. Stir until smooth.

This mixture gives the buns their beautiful golden color.

Step 10: Add Sesame Seeds

1. Preheat the oven to 180°C (350°F).
2. Gently brush each bun with the egg wash.
3. Sprinkle generously with white sesame seeds.
4. Add black sesame seeds if desired for contrast.

The egg wash helps the seeds adhere securely during baking.

Step 11: Bake

1. Place the tray in the center of the preheated oven.
2. Bake for 18–22 minutes.

The buns are done when:

• The tops are golden brown.
• The internal temperature reaches approximately 88–93°C (190–200°F).
• The bottoms sound hollow when tapped.

Step 12: Cool

1. Remove the buns from the oven.
2. Transfer them to a wire rack.
3. Allow them to cool for at least 15 minutes before serving.

Cooling helps the crumb finish setting and improves texture.

Baker’s Tips for Success

Use Bread Flour

Bread flour provides more gluten development, resulting in a softer and chewier bun.

Measure Carefully

For the most accurate results, use a kitchen scale to weigh ingredients.

Do Not Rush the Rising Time

Temperature affects yeast activity. Allow the dough to rise until doubled rather than relying strictly on the clock.

Keep the Dough Soft

A slightly sticky dough produces softer buns than a dry, heavily floured dough.

Store Properly

Store cooled buns in an airtight container at room temperature for up to 3 days.
