Pecan toffee cookie dough brownies are the cure for the largest, most imposing sweet tooth out there. A fudgy, chewy brownie layer is covered with buttery cookie dough that has pecans and toffee bits stirred in. The entire thing is topped with a creamy, rich chocolate ganache then sprinkled with chopped pecans. It's thick, it's gooey, and it's amazingly good. This recipe was originally published in 2008, and included in my first book.
For this recipe you'll need: sugar, brown sugar, all purpose flour, dark cocoa, salt, eggs, butter, vanilla, bittersweet chocolate chips, toffee bits, pecans

You know that recipes tend to be popular in waves, right?
I think that the whole cookie dough brownie recipe phase started in 2008. That's when I remember making these - several times actually. I wanted to include them in a book that I had been commissioned to write because I thought they'd be unusual. After making them about a million times I decided that I didn't like chocolate chips in the cookie dough part because there was almost too much chocolate. Is that even a thing?
It seems to be here.

Anyway, I decided to toss some toffee bits in there and the buttery crunch along with the pecans and creamy cookie dough was just exactly right. They're perfect for long evenings watching movies that make you cry, satisfying the inner demon during bouts of PMS, and sharing with people you love. Or, not sharing at all - because that's ok, too. You're worth it -- and these are worth an extra hour at the gym. Promise.
They're a decadent update from these chewy brownies!
Be sure to keep these tightly covered in the refrigerator. About 20 to 30 minutes before serving time get them out and let them warm up some. Have coffee on hand -- you'll need it.
By the way? My NEW thing, at least for now, is these vanilla brownies. Oh my stars!

There are 2 cups of flour in the cookie dough layer that are not cooked at all? That doesn't make sense.
Marye

I've seen a lot of cookie-layer brownies, but yours is the first I've run into where you make the cookie layer from scratch. I love that!

Hello - I'd like to make these for a work pot luck - but I'm confused by one thing. Your ingredients for brownies calls for butter, but the directions for making them call for oil. Just wanted to clarify which one to use. Thanks!
Marye
Actually you can use either. I think the oil makes them a little more chocolatey and the butter makes them a litter richer.
anne
my church family will LOVE these!!!!
