I guess stuffing cookies and brownies is a new trend. And what a great trend it is. Picky Palate has quite a few recipes with "stuffing".
Here is the one for oreo stuffed chocolate chip cookies
I knew I had seen this recipe recently so I thought, why make it from scratch when I can just throw this together and have the same thing. I now realize there is a reason why some things have recipes. The first batch I made looked AWESOME, until I took it off the cookie sheet and realized the bottom was totally raw. I had already eaten a raw one (sorry mom, I know you hate that) so thought that they weren’t a total waste.
Second attempt, I put very little on the bottom of the oreo and made most of the chocolate chip cookie sit on top. These turned out much better looking and tasted great
