Peanut Butter Marshmallow Chocolate Chip Cookie

Oct 11, 2017

I normally am the type to just follow a recipe and make delicious things, but when it comes to chocolate and peanut butter I LOVE experimenting and trying stuff out, because let’s be honest anyway you combine them is going to be phenomenal. After some trial and error I found my new favorite cookie! It is a peanut butter marshmallow chocolate chip cookie and I can’t get enough of it. It’s so easy to make that I have found myself baking them 2-3 times a week lately! Oops. 

If you don’t think this ooey gooey chewy peanut butter marshmallow chocolate chip cookie is the best thing since sliced bread then you can just get the heck out of here. Just kidding! Try out this recipe of peanut butter and chocolate goodness below and let me know what you guys think. Unless you hate them, because then you’re just wrong.
