If you're looking for a great cake and filling recipe and have a standard chocolate frosting you want to use, this is your recipe. I thought this recipe was really great if for no other reason that I botched it a bit and it still got rave reviews. I accidentally put in 1 cup butter instead of the advised 3/4 cup. It was very dense but for it being a peanut butter cake, I don't think that's a total failure. If I make this again I would probably not add the extra 1/4 cup butter but it certainly wasn't dry like the other reviews have warned. Also, I really loved the filling! My only complaint is that I wasn't so much a fan of the frosting part as the filling. The peanut butter filling is SO EASY and really fancies up the cake. I felt the frosting left a little bit to be desired. Mine came out not too chocolaty. I was afraid it wouldn't be strong enough to couple well with the all that peanut butter so be prepared with a chocolate frosting back up if you like a richer chocolate taste. However, I'll use this recipe again for the cake and filling. Excellent.

I liked the filling, but the didn't have the best results with the cake. I've made it twice, it may be me, but it turned out dry both times, and I didn't care for the flavor, nor did my husband, and chocolate & peanut butter fanatic. I used a homemade chocolate glaze, hoping it would help with the dryness, but no luck. I won't be making it again.

My 14 year old son was craving a PB cake and found this recipe. It was his first ever attempt at baking. Excellent cake recipe, just right on the PB flavor. He baked a sheet cake using the cake mix and frosted it with Fudge Frosting (by Martha). Delicious!
