Easy Cake Mix Bars

I take this dessert to work for Friday pick-me-ups. It's one of my favorite yellow cake bar recipes. I love to share them because they're so easy to eat, easy to make and easy on the wallet. —Amy Rose, Ballwin, Missouri

      I was so excited when I found this recipe! I followed the directions... I'm now going on minute 35 and I still have a mushy center. Kind of a pain, so I hope they're good.

      D., jimmies are sprinkles, like you would put on ice cream or find in confetti cake mix.

      I just made these. They are so dry and crumbly.

      I needed a bar that would be easy to eat if the weather was hot--not gooey or messy. I used chocolate cake mix and sea salt caramel chips. I think they actually got better over the three days we were together with family. I might consider adding more chips next time, but no one complained that there were too few in these!! I didn't have to refrigerate them but I did keep them out of the sun.

      Family thought it was rather plain, just cake with chips and too sweet. Great idea though.

      Used red velvet cake mix and white chocolate chips. As others suggested, used a 13x9 pan. I thought the thickness was appropriate, although, had issues with crumbling after cooling and cutting. Perhaps it's because I live at high altitude? I baked as directed, did not adjust. Interesting and easy recipe with loads of variation options. Would try again.

      This is my favorite quick dessert recipe! Simple ingredients I always have on hand. I have substituted buttermilk and also fat free half and half, perfect, richer touch! My favorite is the yellow cake mix with chocolate chips and the red velvet with white chips. I use the 9x13 glass pan. My family loves these !

      I baked in a stoneware jellyroll pan when completely cool bottom was a bit hard. Still very good. I'll try glass next time
