Kit Kat Cookies

The BEST cookie dough filled with mini Kit Kat candy bars!

You guys! I’m home from the world’s longest vacation!

Okay, so it was only two weeks away, but have you ever been gone from your house for two entire weeks? It’s kind of crazy.

I can’t remember where things go in the kitchen. Whose idea was it to keep the cutting boards there anyway?

I keep opening the door to the basement when I mean to open the door to the linen closet. Granted, they’re close to each other, but still.

Also, my husband doesn’t know how to work our fancy new high tech dishwasher with all the buttons, so he thought he started the dishwasher two weeks ago and then I came home and opened it to discover mold all up in everything. It was the least pleasant thing I’ve ever seen. Fact.

But, vacation was lovely. A week at the beach, followed by a week of family time, followed by a day in Chicago with my daughter, her friend, and my friend for a little American Girl time. See also: I’m totally broke now.

I paid $25 for my daughter’s doll to get an up-do. Because, the doll totally had a fundraising gala to attend that night or something. Not sure.

Anyway! I’m home and I have cookies.

These are just your basic chocolate chip cookie dough, and by that I mean, these are amazing. I love chocolate chip cookies and this is my all time favorite dough recipe.  I snagged it from Sally’s Baking Addiction who snagged it from Anna Olson and now I insist that you snag it and add it to your personal recipe book, because man, these are the best cookies ever.

I loaded these up with the eensy weensy Kit Kat bars you can buy in a small bag. So many people like nuts in their cookies, so I thought the Kit Kat bars would replicate the nutty crunch nicely and I was right! The textures are fun and the flavors are amazing, and basically you should stop reading this and get in the kitchen right now!

Cookies for all!

    Welcome back, Karly! I can’t believe it cost $25 for your daughter’s doll to get an up-do? I have boys, so I’ve got no idea about any of that stuff. :) These cookies look amazing, and I love Kit-Kat bars!

    I’m pretty sure I’d prefer kit kats in my cookies to nuts. These look phenomenal!!

    oooh 2 weeks IS a long vacay-I’m glad you had fun though (and…apparently your daughter’s doll? charity galas and whatnot). I LOVE these cookies-they look so gooey and delish!

    I love these! Every time I see those mini Kit-Kats at the checkout line I just KNOW they all want to be cookies when they grow up. Can’t wait to try out your recipe, now that you’ve done all the hard work for me! 😛

    I don’t eat many candy bars. Its the one thing I can resist. Now fine chocolates like truffles—-that is another story. But kit kats are one that I do eat. It would be fun to use them in cookies. This basic cookie recipe is different than mine. I am curious to try it. I bake a lot of cookies with variations on my basic cookie.
    I am open to change to obtain more perfection. Lol

    Welcome back! These are such a great idea! This is the favorite candy bar of one of my sons. I’m going to make these for his birthday. Thank you!

    Can’t go wrong stuffing cookies with Kit Kat minis!

    Coming home to mold is like…my worst nightmare. But coming home to kit kats cookies would kind of be the best! So…balance?
