Preparing Japanese Red Bean Buns (Anpan)
Making Japanese Red Bean Buns, or Anpan, is a delightful journey into the world of Japanese baking. These fluffy buns are not only a treat for your taste buds but also a joy to create. Follow these simple steps, and soon you'll be indulging in these sweet delights.
Make the Tangzhong
The secret to soft and fluffy buns lies in a technique called Tangzhong. It’s easy:
- Combine 14 g of white bread flour with 100 ml of milk in a small saucepan.
- Whisk the ingredients together over low heat until it forms a thick paste. You want it to be thick enough that your whisk leaves lines in the mixture.
- Cool the Tangzhong in a bowl before using it in the dough. This step is essential for moisture retention, making your Japanese Red Bean Buns irresistibly soft.
Prepare the Japanese Milk Bread Dough
Once your Tangzhong is cooled, it’s time to start on the dough:
- Mix 350 g of bread flour, 3 g of instant dried yeast, 6 g of fine salt, and 55 g of caster sugar in the bowl of your electric mixer.
- Add the egg and cooled Tangzhong to the dry ingredients, followed by 125 ml of warmed milk.
- Knead the dough for about 10–15 minutes until it passes the windowpane test. This means the dough should stretch without tearing, letting light through.
Portion the Red Bean Filling
While your dough is rising, prepare the filling:
- Scoop 270 g of fridge-cold red bean paste and divide it into 9 equal portions (about 30 g each).
- Roll each into a ball. Keeping it cold makes for easier handling.
Shape the Dough
Once your dough has risen:
- Divide the dough into 9 equal portions.
- Flatten each piece to about 8-10 cm in diameter, place a ball of red bean filling in the center, and wrap it up by pulling the edges into the center.
- Pinch the edges together and roll into a nice ball. Place each bun seam-side down on a lined baking sheet.
Prove the Shaped Dough
Now, let’s let those buns rise again:
- Cover them with a clean tea towel and place them in a warm spot for about 30 minutes, or until they’ve nearly doubled in size. What a wonderful sight!
Bake the Red Bean Buns
Finally, it’s time to bake:
- Preheat your oven to 180°C (356°F).
- Brush the tops of the buns with an egg wash and sprinkle black sesame seeds on top.
- Bake for 20-25 minutes until they are lightly golden. Let them cool slightly on a wire rack.
Enjoy your freshly baked Japanese Red Bean Buns warm or at room temperature! Perfect for an afternoon snack or dessert.

Variations on Japanese Red Bean Buns
Matcha Red Bean Buns
If you’re a fan of matcha and Japanese red bean buns, take your baking to a whole new level by infusing your dough with this vibrant green tea powder. Just add a tablespoon or two of high-quality matcha during the mixing process. This not only adds a beautiful color but introduces an earthy, slightly bitter contrast that pairs perfectly with the sweetness of the red bean paste. Plus, matcha is packed with antioxidants, making these buns a deliciously wholesome treat!
Chocolate Red Bean Buns
Craving a sweet twist? Try making chocolate red bean buns! Incorporate cocoa powder into the dough—about 2-3 tablespoons should do the trick. This adds a rich chocolate flavor, turning your traditional Japanese red bean buns into an indulgent dessert that still holds that soft, fluffy texture. You could even fold in some chocolate chips for extra decadence. Serve them warm, and you’ve got a unique treat that’s perfect with a cup of tea or coffee.

Cooking Tips and Notes for Japanese Red Bean Buns
Understanding the Windowpane Test
Achieving the perfect Japanese Red Bean Buns starts with kneading your dough correctly. The windowpane test is crucial—gently stretch a small piece of dough; if it forms a translucent sheet, you've nailed it! This means the gluten is well-developed, ensuring your buns will be beautifully soft and fluffy. If it's too thick or tears, keep kneading.
Make-ahead Strategies
Planning ahead makes everything smoother! You can prepare the dough the night before: after kneading, cover it and let it rise in the fridge overnight. This slow fermentation enhances flavor, but you may need a bit more time for the second rise. This is a great way to enjoy freshly baked Japanese Red Bean Buns even on a busy morning!

You could also consider serving them alongside some fresh fruit, like sliced oranges or a berry medley, for a refreshing twist.
