Discover the Deliciousness of Purple Sweet Potato Hokkaido Milk Bread

Purple sweet potato Hokkaido milk bread is a light and fluffy pull apart Japanese bread which is very easy to make!

It is originally made with cow milk, butter and eggs. To make it dairy-free and egg-free, I used oat milk and coconut milk powder, which make it light and fluffy. I used purple sweet potato powder to make it pink and pretty. Feel free to omit if you’re not able to find it.

Introduction about Purple sweet potato Hokkaido milk bread

Purple Sweet Potato Japanese Milk Bread by foodie.yuki | Quick & Easy Recipe | The Feedfeed

The best flour to make this kind of bread is bread flour, which correspond to type 0 in Europe.

This bread is soft and sweet and it’s a perfect breakfast or afternoon tea bread. Spread some jam or nut butter for even more yumminess!

This recipe is much easier than you could think. You only need a stand mixer fitted with the hook attachment or a kneading machine.

As for other milk bread recipes, I made a bread starter (or roux or Tangzhong) which is the key to a fluffy and moist texture. This is made by cooking some bread flour with water and milk until a curd-like mixture is formed.

You will then add this mixture to the other ingredients and knead until an elastic dough forms.

Please note that the milk temperature is very important in this recipe. The instant yeast needs some warm liquid to be activated, but if it’s too hot, the temperature will kill the yeast and the dough won’t raise properly. I highly recommend you buying a kitchen thermometer because it is very useful for this and many other recipes.

Also note that the resting/rising time is very important to make a bread that has an even and perfectly baked texture. Make sure you follow the instructions and that your dough has properly risen before proceeding with the next step.

I used a 22cm loaf pan to make this bread. If you’re using a smaller pan, the bread will rise higher and could take some more time to bake. I don’t recommend using a larger pan with this amount of dough, because the bread will grow more in width rather than in height.

I hope you will give this recipe a try so that you can see by yourself how easy it is to make homemade healthy milk bread!

I’d love to have a feedback from you if you try my recipe!

  • Use high-quality ingredients: Use high-quality flour, purple sweet potato, and milk to ensure that the bread has a delicious flavor and texture.
