So my husband has taken up juicing…

He went out and bought a juicer and is now all about new “juices”.

This means he spends infinity dollars on produce daily. Because how much juice do you think comes out of a head of broccoli? Like 2 teaspoons. So basically to get enough juice to fill a Dixie cup you have to buy 45 heads of broccoli.

And 45 heads of broccoli is expensive.

Also are Dixie cups still a thing? I used to drink from them all the time when I was a child…and now I can’t even remember the last time I SAW one.

I mean, really they are kind of annoying, they only hold like 1/4 cup of liquid.

Anyhow, back to my husband’s juice.

Like I said you have to buy a LOT of veggies and fruit to actually make a glass, which means my refrigerator is filled with kale and spinach and beets and broccoli and things with weird odors.

I have no room left for pitchers of lemonade or coffee creamer. It’s becoming an issue.

And might I just say when my husband makes this juice, it’s the color of poop after you’ve been to a birthday party and eaten a piece of cake with a giant green flower.

Yeah, there’s a visual for you.

So it looks sick, smells weird and takes up all my lemonade space.

But it’s “healthy”. So there’s that.

Homemade Oreo Dessert Bar Recipe

Anyway, the whole point of my story is that I made these Potluck Oreo Bars, which need to be refrigerated, but I had no room in the fridge for my Oreo bars because of all the kale, which forced me to eat all the bars.

So basically my husband’s juice is making me fat.

Thanks for that.

Tips and Tricks on Making Cake Mix Oreo Bars:

The beauty of these bars is that they start with a cake mix. Which again, I know some of you hate. But it’s just the nature of the beast today.

Base starts with a chocolate cake mix..

You use the cake mix as a thick base and then top it with a creamy cheese mixture…

Bake it up like this…

  1. I’m just wondering about the cream cheese mixture. It says to mix in the chopped chunks of Oreos, but the pic shown of when spread on top of the baked cake layer, it looks smooth without any chunks showing, as if the Oreos were ground first. You only seem to see the chunks that are sprinkled on top. Is it just that the chunks remain hidden that were mixed in? They look delicious!

    wow do those look and sound amazing. I am going to have to try them out soon and some of those other yummy sounding recipes too. I willhave to bookmark this page for sure! I just want to say I absolutely LOVED your post. You had me laughing all the way through!

  3. This looks amazing! Just one question…does the recipe really need 4 CUPS of powdered sugar? I’m all for sweet, but that seems excessive

    1. The powdered sugar yes sweetens, but in this case helps with the consistency. If you would like to add less, give it a try! I am sure it will be good, the topping might not be as firm, though!
