I've never met someone who loves the peanut butter-chocolate combination as much as this boy does. For Valentine's Day, I sent him a 1-pound peanut butter cup, and when the company failed to deliver it by the holiday they sent him another one for free. He hadn't even opened the second one, so we chopped it up and used it in these bars.
Just as Averie describes in her post, this recipe is super easy. The cookie dough base and the "crumble" on top are made from the same batter, and the filling is just chopped pb cups and sweetened condensed milk, which makes them melt-in-your-mouth gooey. Also, as per her instructions, make sure to let these bars sit for at least three hours after baking. While it's tempting to dig right in, the soft center needs to set before cutting.
If your significant other/friends are anything like mine, these will be gone within the day. This recipe only made around 16 bars (which seems like a lot but really isn't when they're being eaten by six people) so I would suggest doubling it and baking them in a 9x13 inch pan.
My favorite helper, trying (unsuccessfully) to talk and chew. You can find this recipe in the link at the top of the post!
