These are like peanut butter fudge marries a brownie! I just had these at my friend Sue's house - to die for. DH asked her for the recipe. I was going to post it but here it is!!
Please tell your MIL we thought this recipe was Perfect!!! The peanut butter layer wasn't so sweet that it overpowered the great chocolate taste. A great combo. For a quicker version, I may try using a packaged brownie mix with the PB layer.Thanks so much for posting!
