Flourless Peanut Butter Nutella S’Mores Sandwich Cookies

Flourless Peanut Butter Nutella S’Mores Sandwich Cookies are ridiculously fun, ridiculously good, ridiculously large (if we are being perfectly honest), and it would be ridiculously silly if you didn’t make them! Nutella and marshmallow buttercream, sandwiched between two super peanut-buttery cookies.

Food blogger secret – make one basic recipe, split it up and make several variations. Then, spread the posts out just enough, or use one as a guest post on someone else’s blog, and WHAM – holiday time saver! Sorry, it’s that time of year, we all have to cut corners. And I’ll tell you, you can probably cut corners with this recipe and use a jar of marshmallow fluff, but the marshmallow buttercream is just one of the most unique and fun recipes I’ve tried, so give it a shot.

And then get ready to have your mind blown. Flourless peanut butter cookies just have the most intense peanut butter flavor, and since they are tender and not too sweet, they are perfect for sandwiching gooey, chocolaty Nutella and a fluffy marshmallow buttercream. This is seriously like a bite (a very large bite – these aren’t dainty cookies) of heaven, because I don’t know about you, but my version of heaven has marshmallow clouds, and flowing rivers of peanut  butter and chocolate. Basically, you know, Willy Wonka.

Another holiday time saver – make up a batch of Flourless Peanut Butter Nutella S’Mores Sandwich Cookies, wrap them up individually with some pretty cellophane and ribbon, and freeze them.

If you receive an unexpected gift or overnight guest, wrap a couple up with a cute holiday mug and some hot cocoa mix. They are actually pretty easy to make, and once you get the assembly line going, don’t take very long, either. But they look impressive and taste, well, as I said…  ridiculous!!

Do you have a good basic cookie dough recipe that you use to make several different varieties?
