Story Behind this Recipe
My daughter sometimes has a bit of constipation so I wanted to make her a healthy and delicious snack that's full of dietary fiber.
Cocoa powder clumps up in high humidity, so if that happens, sift it before use. The recipe only uses a small amount of oil and sugar, so it has a really simple, light taste. For adults you may want to add chocolate chips or butter to increase the sweetness for a satisfying dessert.
