Finely chop the mochi rice cakes and heat them in the microwave with milk until they become soft and chewy. Mix in kinako (roasted soybean flour), sugar, egg, and pancake mix to make the batter, then cook in a frying pan. This is a recipe for Japanese-style pancakes with a chewy and moist texture, similar to a memory foam pillow. Enjoy them with powdered sugar or syrup to your liking.
