Hooray for super simple, soft, and chewy cookie bars!

I can’t tell you how many time these cake mix bars have literally saved my life!  Ok, maybe not my LIFE, but they’ve definitely saved my behind a time or two when I needed treats, and I needed them now.

Like that time your kiddo comes home from school and announces they forgot to tell you, but they signed up to bring treats to the class party….TOMORROW.

Always keep cake mix around, I’m telling you!

This week these bars have been a lifesaver in the form of something to do with the kids!

They love making these.  I love that it keeps us inside, in the air conditioning.

The beauty here is that you can use any candy your heart desires!

We always have chocolate chips around, so that’s what we went with for this post.

They’re really, really, beyond good with butterscotch chips, M&M’s, chopped Butterfinger candy bars. You name it!

You know how much I love Butterscotch if you’ve checked out my Butterscotch chip cookies.  The flavor that always gets my seal of approval first!

  2. I addd toffee chips and peanut butter chips. Spread in the 9×13 and sprinkled a cup of captain crunch on top. Yellow mix and it was a HIT!! First thing gone on the dessert table! Thank you!

    I took this to a New Years party – I used mini chocolate chips, just over a cup, and I iced it with buttercream. It was a big hit and there was none left to bring home!

    I may never make chocolate chip cookies again! This was by far the easiest recipe ever. I kept muttering “oh my gosh, these are so good” to myself while sampling them and was thrilled when they wouldn’t all fit on the serving dish I was using so I could keep a few for myself!

    I had a bag of Nestle “morsels & more” (white chocolate chips, graham cracker bits and strawberry flavored chunks) that I think I grabbed around spring that’s been begging to be used. I’m not even sure why I bought the bag as I’m not a huge fan of white chocolate! I guess the clearance price sucked me in LOL So I decided to look online for an easy cookie receipe using cake mix (with butter, not oil) and yours popped up. It was tempting to wait, but Oh my, sooo good! I’m almost wishing I had saved the recipe and made them to bring for the dessert table next Thursday for Thanksgiving instead of my usual cupcakes! Hmm, I wonder if they sell other seasonal combinations. Maybe I can make the bars for our cookie swap next month!
    Thanks for sharing the simple & easy recipe!
