Marshmallow Whoopie Pie
And I don't know why I haven't made them before. They're delicious! They look like a cookies but they're cakey in the middle. I used the recipe from here, and they were really easy to make. If you haven't checked out Sorted Food already, I highly recommend them! I typed up the recipe on my typewriter and I'm planning on making a little personal recipe book at somepoint and displaying the typewritten pieces along with a photo. I'll do a DIY of that here on the blog once I've got enough recipes under my belt!
I filled most of mine with marshmallow fluff which was delicious! You can fill them with nutella, or chocolate spread or whatever you fancy really! They are incredibly moorish, so be warned!
