Blend all the dry ingredients together, and then add all the wet ingredients and blend well.
On baking sheets covered with parchment paper or a baking mat (such as a Silpat), place about 2 tablespoons at least 2 inches apart in circles, across the sheet.
Bake for 15 minutes, or until a toothpick comes out clean.
Cool completely - at least 15 minutes - before sliding them off the mat with a spatula.
Take one pie and spread frosting on it. Place another pie on top of the frosting. Serve.
