Kabocha Ghost Rice Flour Cake
かぼちゃのおばけ米粉ケーキ
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
These little "obake" (ghost) cakes are a Halloween treat from the preschool snack menu. Mashed kabocha squash gives the batter its natural sweetness and golden color, and the rest of the batter is rice flour, potato starch, soy milk, oil, sugar and baking powder. The cake is made without egg, milk or wheat. Once the cake is cut into pieces, a simple cocoa sauce is all you need to draw a friendly ghost face on each one.

Values are per serving (1.5× the Japanese preschool portion); an adult serving is double. They were calculated by a licensed Japanese nutritionist using the Standard Tables of Food Composition in Japan. "Salt equivalent" is sodium × 2.54, the standard Japanese measure. Allergen flags cover egg, milk and wheat only and come from the nutritionist's records. Soy sauce and miso are made with wheat but are usually allowed on Japanese wheat-free school menus, so check with your doctor.
