Katzen's Chocolate Peanut Butter Brownies

Recipe by Katzen

A happy experiment, born some extra peanut butter and peanut butter chips, and a need for an awesome brownie recipe. DH said they were Outstanding - and this from a guy whose high praise usually comes in the form of a grunted, "good".

Totally drool worthy! I used Splenda for the sugar and Adams (natural) peanut butter and skipped any nuts to keep DH happy. They are so rich and wonderful that I can't say that I think there would be a real benefit in adding nuts. Made just a half amount of the icing and just placed a small dollop in the center of each brownie. Perfectly delicious and rather decadent, whats not to love?
