I saw this recipe (if you can even call it a recipe) on a blog and HAD to try it. I can't even remember which blog it was.
Start by making regular brownie mix as directed on the package

Then you'll need 3 large candy bars. On the blog I saw this on, she said she used all Symphony bars. But they weren't on sale and the others were so I thought I'd mix things up

pour half of the brownie batter in a 9x13 pan and top with the candy bars


Pour the remaining batter over the top of the candy bars and bake as directed on package ( I cooked mine the longest time listed and they turned out perfect)

Enjoy! I have to say that the coconut ones were my favorite followed by the Symphony and no one thought the Butterfingers were that great. I will make these again for sure!

(horrible picture, I know. I don't have the patience to let them cool completely)
