Easy Fluffy Sweet Potato Steamed Bread (Mushipan) Recipe

Fluffy Autumn Sweet Potato Mushipan (Satsumaimo no Mushipan)

As the mornings and evenings grow cooler, the crisp air tells us that autumn has truly arrived. In Japan, this is the season for Satsumaimo (sweet potatoes).

Warm Mushipan (Japanese steamed bread), freshly made with plenty of steam, is the perfect treat for this chilly season. These steamed buns are gently sweet, light on the stomach, and make for an excellent snack or breakfast.

While this is a traditional recipe, feel free to get creative! You can easily customize the toppings with cocoa, matcha, brown sugar, or raisins. You can also swap the milk for water for a lighter finish or heavy cream for a richer taste.

The Secret to the “Mountain” Peak

You may notice some mushipan are flat while others have a beautiful, cracked “mountain” surface. This is determined by the water ratio and steaming temperature. A higher temperature causes the dough to expand rapidly, creating those signature cracks that many people love!

Satsumaimo Mushipan Cooking Instructions

Prep the Potatoes: Wash the sweet potatoes thoroughly and cut them into 1cm cubes. Soak in water for 5 minutes to remove excess starch.
Microwave: Drain the cubes lightly (leave a little moisture so they don’t dry out). Sprinkle with 10g of sugar, cover with plastic wrap, and microwave for 3 minutes until tender.
Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, 60g sugar, and salt until well combined.
Combine: Add the milk and mix gently with a rubber spatula. Fold in the oil and the cooled sweet potato cubes.
Prepare the Steamer: Pour the batter into heat-resistant containers or silicone molds. Add about 1cm of water to a frying pan and bring to a boil.
Steam: Place the containers into the pan. Cover with a lid, leaving a tiny gap for air to escape.
- Steam for 20 minutes if making 4 large portions.
- Steam for 13 minutes if making 6 smaller portions.
Finish: Maintain a gentle boil throughout. Check for doneness by inserting a skewer; if it comes out clean, your Mushipan is ready!
