Chocolate cake cookie bars with a white chocolate chewy layer baked right in.  Chocolate Cake Cookies Bars are like a reverse revel bar without oats.

I don’t have anything against oats.  They have their time and place.

Just not in my cookie bars!

I wanted to call these Leopard Bars, but I was shot down.

Chocolate Cake Cookie Bars look like they are wearing leopard print if you ask me!

If I wanted an oatmeal cookie with some fudge filling, I would just make an oatmeal cookie with fudge filling.

It’s been a hot minute since someone made a cookie bar very similar to this one for me.

It is important to make sure that the bottom cake mix cookie layer has no holes in it.

There should also be no places that have so little batter that the gooey filling can slip through.

Raising my hand over here because it has happened to be at least twice during recipe development.

If that happens, it will be almost impossible to get the bars out of the pan in one pretty piece.

The edges of the cookie bars are going to be chewier than the bars from the middle, just like with brownies.

But, those pieces taste the best I think!

The edge chocolate cake cookie bars are almost like a slow-cooked caramel wrapped in a chewy brownie.

Allow this recipe to cool completely before attempting to cut it.

The filling needs a chance to firm back up just a bit before it will all hold together.

Once cooled and cut the cookie bars can be stored at room temperature for a day or so before they start to go stale.

To keep them fresh, store in an air-tight container and they should stay soft for up to 4 days.

It’s my guess that just about any cake mix flavor could be combined with just about any baking chip flavor.
