Oreo Cake Bars

I actually wanted to work on these last month but my husband ate the brand new bag of oreos that were in the house.  Oh, you know how husbands can be.  I went looking for them and noticed that the empty bag was in the trash so this oreo cake bars recipe was put on hold.

It probably wasn’t a bad idea that I waited until AFTER lent to feature this oreo cake bars dessert because you might eat a bit more than you should.  These were oh so tasty.

I knew the ultimate pairing for oreos had to be the gooey gooey cake.  Most people have heard of this cake due to Paula Deen but we had the original recipe in my family for decades and it originated in St. Louis, where my Aunt Bev lives.  It has been a family favorite forever.

For these oreo cake bars, I created a chocolate version that was awesome paired with the cream cheese cool whip oreo topping. Seriously go make these and hand them out at work next week.  Your co-workers will nominate you as “Employee of the Month” right away.

    Holy oreo cookie cake bars!!! WOW! I love how the previous bag of oreos just happened to disappear! :} When my daughter lived at home, my goodies would always disappear too. She would always say there was a mouse in the kitchen. Your story reminded me of that and made me laugh! Enjoy your week, Jocelyn!!!

      Hi Cassie, yes, cool whip is a whipped cream topping found in the freezer section of your local grocery store. You can also use your own fresh whipped cream if you would like. I can’t wait to hear how it turns out for you.
