Thick and chewy peanut butter oat cookies sandwich a salted honey butter cream filling.

Notes: The buttercream frosting can be tailored to your taste: add more salt if you like, and choose your favorite honey. Just use a honey with a strong flavor (such as wildflower or orange blossom) or else you'll end up with a frosting that tastes like sugar, not honey. I go pretty light on the amount of buttercream per sandwich in order to keep things from getting too intense; feel free to add more if you like.
