Cookies and Cream Double Chocolate Cake Bars

Okay, so I really really really love Picky Palate  I don't know if you have every been there, if not you need to check out her site.  That is where I got this HEAVENLY idea...

I forgot to take pics of the before when I mixed it all together.  But I do have pics of the before the oven and of coarse the after.

She is wonderful at explaining the recipe and taking pics to help you along.
I did change the recipe a bit...

I added both regular and mint oreos.  One side was mint the other regular, since my husband likes the mint better and I like the regular.
