I can’t believe I have waited this long to make these! They are so super cute and so easy to make. I have to admit that I had never even heard of whoopie pies until about six months ago.

I know, I know…where have I been right? This was my first batch and I was very excited to take that first yummy bite that you see in the picture above! 🙂 Two chocolatey cake cookies with a luscious marshmallow creme filling layered in between. Does it get any better than this? I think not!
