Easy Japanese Milk Bread Recipe (Soft and Fluffy)

Japanese milk bread, also known as Shokupan, gets much of its wonderful texture from a simple technique called Tangzhong. It involves cooking a small amount of flour with milk before adding it to the dough. Don’t let the name intimidate you; it’s one of the easiest parts of the recipe.

I’ll show you how I make the dough, how to tell when it has been kneaded enough, and how to shape it into the beautiful loaf you see in my photos.

What Is Japanese Milk Bread?

Japanese milk bread, or Shokupan, is a soft, slightly sweet bread commonly enjoyed for sandwiches, toast, and breakfast.

It has a fine, fluffy crumb and a tender crust. Unlike some breads that have a chewy interior and a firm crust, Japanese milk bread is soft throughout.

You can bake it with a rounded top, as I do in this recipe, or in a lidded Pullman loaf pan for square slices.

Why I Use All-Purpose Flour

Many Japanese milk bread recipes call for bread flour, but I use all-purpose flour because it’s an ingredient most people already have in their kitchens.

Bread flour contains more protein, which helps develop stronger gluten. It can produce a slightly chewier bread with more structure.

All-purpose flour gives my milk bread a beautifully soft and tender texture. You can use bread flour instead if you prefer, but the dough may feel a little different when kneading and shaping.

One thing I particularly like about the dough made with all-purpose flour is how easily I can shape it with my hands. I don’t always need a rolling pin.

How to Make Japanese Milk Bread

The process is straightforward: prepare the Tangzhong, knead the dough, let it rise, shape it, and bake.

If this is your first time making milk bread, follow the step-by-step photos. Pay particular attention to how the dough changes during kneading and proofing.

Step 1: Prepare the Tangzhong

In a small saucepan, combine 2 tablespoons of flour with ½ cup of whole milk while the pan is still off the heat.

Whisk until there are no lumps.

Place the saucepan over medium heat and stir continuously until the mixture thickens to a pudding-like consistency.

Turn off the heat and add the remaining ½ cup of milk. Whisk until smooth.

Let the mixture cool until it is warm rather than hot. Add the sugar and yeast, and whisk to combine. Then add the egg and mix well.

Step 2: Make the Dough

Add the flour and salt to the bowl of a stand mixer fitted with a dough hook.

Pour in the Tangzhong mixture and begin kneading.

After about 2 minutes, when the dough starts coming together, gradually add the melted butter.

Continue kneading for approximately 10 minutes.

At first, the dough will feel sticky. As you knead, it becomes smoother and more elastic and begins pulling away from the sides of the mixer bowl.

Here’s how I know my dough is ready: It reaches a stage where it doesn’t just pull away from the bowl; I can press it with the back of a spatula, and the dough won’t stick to it.

I also check it using the windowpane test.

Step 3: Check the Dough with the Windowpane Test

Take a small piece of dough and gently stretch it between your fingers.

If you can stretch it thin enough to see light through it without tearing, the gluten has developed well.

If the dough tears quickly, continue kneading for a little longer and check again.

Don’t be tempted to add extra flour just because the dough feels sticky at the beginning. Give the mixer time to develop the dough first.

Step 4: Let the Dough Rise

Lightly grease a large bowl and place the dough inside.

Cover and leave it in a warm place for approximately 1½–2 hours, or until it has roughly doubled in size.

The time depends on your kitchen temperature. If your kitchen is cool, the dough may take longer to rise.

Step 5: Divide and Shape the Dough

Gently press the risen dough to release excess gas.

Divide it into four equal portions and shape each into a ball.

For the loaf shown in my photographs, I used three portions in an 8½ × 4½-inch loaf pan and turned the fourth portion into buns.

Why? I didn’t have a loaf pan large enough to fit all four portions while giving me the appearance I wanted. I also thought it would be a good opportunity to see how this dough would behave as buns.

I’m glad I tried it! The buns tasted just as good as the loaf and had a similarly light, fluffy texture.

To shape each portion:

1. Flatten or roll the dough into a rectangle approximately 8–9 inches long. With all-purpose flour, I can usually do this with my hands.
2. Fold the top toward the center.
3. Fold the bottom over the first fold.
4. Rotate the folded dough 90 degrees.
5. Roll it up and pinch the seam closed.

Place the rolls in the greased loaf pan with the seams facing down.

Repeat with the remaining portions.

Step 6: Let the Shaped Dough Rise Again

Cover the loaf pan and leave the dough to rise for approximately 30–40 minutes.

Don’t rely only on the time. The rolls should look plump, touch one another, and rise slightly above the rim of the pan.

That’s how the dough looks in my photograph just before I brush it with egg wash.

If the rolls are still sitting low in the pan after 40 minutes, give them more time.

Step 7: Bake the Japanese Milk Bread

Preheat the oven to 350°F (180°C).

Beat an egg with 2 tablespoons of water and lightly brush the risen dough with the egg wash.

Bake for approximately 20–25 minutes, or until the top is beautifully golden brown and the loaf is baked through.

Remove the loaf from the oven and leave it in the pan for about 10 minutes.

Then transfer it to a wire rack to cool.

💡Tip: Sometimes, I brush the top with a little butter after baking for extra flavor. This is optional, but it’s a nice finishing touch.

If you made buns with the remaining dough, they usually take approximately 12–14 minutes at the same oven temperature, depending on their size.
