Lotte will release "Custard Cake [Rombosse Tailoring]" on September 11th. Autumn only. It comes in 6 pieces, and the estimated price is around 300 yen (excluding tax).
This is a custard cake with apple custard cream and roasted apple-flavored sauce. It is said that the taste of roasted apples is a combination of the taste of sweet apples and the taste of cinnamon with a slight scent.
Also, if you bake it in an 800W oven toaster for about 2 minutes, you can enjoy "crispy cake" and "thick cream".
