    Sorry for my absence on social media and the blog lately. I have been super busy with assignments and working on a few fun projects you will hear about soon!

    I hope you enjoy KitKats as much as I do because today you have soft and chewy chocolate chip cookie bars filled to the brim KitKats.

    Today's recipe comes complete with a video tutorial!

    The cookie bar base is my classic cookie pie recipe that I use for most of my cookie bars and pies as it yields gorgeous, soft and chewy cookie bars EVERY. SINGLE. TIME!

    How to make the KitKat Cookie Bars

    The base recipe for the cookie dough is very easy. One bowl is all that is needed. The key is to not completely melt the butter. You want partially melted butter which means that lumps of butter should remain.

    If you do accidently melt the butter completely (I know, it happens), You can add 2 extra tablespoons of flour to counteract the extra liquid.

    We also use two big blocks of KitKats in these cookie bars so you know they are going to be amazing!

    We add KitKats on top of the cookie bars but only once the bars are finished baking. We add them as soon as the cookie bars are out of the oven so they melt slightly without burning.
