This recipes uses 4 stackable Moon Pie pans with 6 pie indents each. The photos are of Ramen Buns made without arrowroot flour. This was my first attempt at making these. They turned out great but I was trying to think of a way to bind them together a bit more for easier handling. Then I thought of how much we love arrowroot flour in our favorite recipe for chocolate cupcakes and figured it would add a cake like flavor to the Ramen Buns as well as bind them together a tad bit more. It worked nicely but is not essential to the recipe. Note that arrowroot flour happens to also be gluten-free.
