Vegan Pumpkin Whoopie Pies

Whoopie pies are pretty expensive at the vegan bakery in my town, so I scrounged around and found two good-looking recipes on two different blogs. The first blog said that the result was tasty, but the texture wasn't spongy enough. So I used the filling recipe from there and found the cake recipe on another blog. The result is fantastic. NOTES: (1) The brown sugar is hard to blend in really well when it's clumpy, and so is the flour when the wet and dry ingredients come together. An electric mixer can probably fix that problem. (2) The recommended brands in the US for the egg replacer, vegan cream cheese and vegan butter, respectively, are Ener-G, Tofutti Better Than Cream Cheese and Earth Balance. (3) As the first reviewer noted, these spongy pies are prone to both dry out fast and take on moisture. I wrapped mine individually in Saran wrap, but a more natural solution is to store them with a piece of stale bread, or just gather together a bunch of people and eat them in one go!
