Sweet potato cake with a smooth texture


Sweet potato(スイートポテト)

What kind of dish is sweet potato??

Sweet potato paste mixed with butter and fresh cream and baked in the oven.

It’s easy to make a lot, so it’s good to freeze it and save it. If you heat it for a long time, it will easily become dry, so try to brown it in a short time.

It’s convenient to have a food processor, but if you don’t have one, mash the sweet potatoes with a fork.


  • sweet potato 750g
  • butter 60g
  • low-fat whipped cream 50g
  • egg
  • sugar 100g
  • vanilla essence 3g
  • egg yolk

⋈*The kind of sweet potato that I often use is “Kanta-kun”. It is a special product of Oita. Compared to general sweet potatoes, such as long-term storage, it is produced with a lot of effort. Sweetness like sweets is attractive.

➀Sweet potatoes are boiled or steamed in a pressure cooker.

②Mix sweet potato, butter, fresh cream, egg, sugar and vanilla essence in a food processor. (Divided into 3 batches due to the large amount.)

③Flatten it on a bat and cool it in the refrigerator for 1 hour.

④Divide into 50g and round. Oval type is also acceptable.

⑤Preheat the oven to 200 degrees. (200 degrees Celsius is 392 degrees Fahrenheit.)

⑥Apply plenty of egg yolk and bake on the top shelf of the oven for 15 minutes. Mixing a small amount of milk with the egg will make it easier to coat, but if you mix too much, it will be difficult for the egg to brown, so be careful.

⋈*The oven I use is Toshiba’s “Ishigama Dome”. I like that it won’t break even after 10 years of use and is easy to clean.
