While I'm a true peanut butter lover, this recipe was made as a gift for a friend of mine (well, minus one sizeable piece, so I could perform a taste-test)! I followed the directions right on down, to & including a light drizzle of hot fudge topping! And, at the very least, this is definitely ONE OF THE BEST PB CAKES, at least of those I've tasted! Thanks for sharing the recipe! [Tagged, made & reviewed for one of my adoptees at the tail end of the current Pick A Chef]
