These red velvet whoopie pies are little mounds of cake filled with a traditional cream cheese frosting. If you like, you can dust the edges of the frosting with chopped toasted walnuts, just like traditional red velvet cake.
When I first started playing around with baking, I was briefly obsessed with whoopie pies. I bought a cookbook (affiliate link), a whoopie pie pan (you don't need one), but I never actually made any because my bread obsession took over my baking life.
