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!
