Peanut Butter Filled Chocolate Cupcakes with Fluffy Frosting - gluten free dairy free

Well, I guess no one is going to feel too sorry for me as the Easter candy invades. Though I can't eat most of it, my husband just whipped up a batch of treats that will surpass any basket confection. Starting with the King Arthur gluten free chocolate cake mix (my favorite), he stuffed these cupcakes with a peanut butter filling that consists of peanut butter, Earth Balance butter spread, and confectioners sugar (just like the filling used here). For filling, he followed the Wilton instructions here, and used the recommended tip. He topped them with a traditional white meringue frosting (just like this one, but he omitted the lemon).
End result? Delicious. These can easily compete with the boutique gluten free pastries we have tried in downtown Chicago as well as from BabyCakes in Orlando.
