i made just the cake with a different frosting but the cake seemed too light and dry. if i made it again i would add some oats and do something to keep it moister. i did make it a sheet cake but i wasnt overly impressed. i topped it with delicious pb chocolate frosting though so that helped it a lot. i do like that it had less butter than other recipes.

I made mine into a 9" double layer cake... the layers were a little short, but no one seemed to mind (an 8" pan probably would have worked perfectly). I baked each layer for about 24 minutes at 325. I also made twice the amount of icing to be sure I had enough (I did basket weave and flowers so needed extra, but had plenty leftover) and also used the milk instead of juice-- whole or half&half might be better. thanks for a great recipe!

Awesome recipe! I am enjoying my 4th piece today :). I baked it for just 32 minutes and it came out perfect; I suspect 45 is a little too long. I also upped the peanut butter in the cake to a 1/2 cup, which doubtless affected the baking time (though I would have expected it to increase it...). Potentially because of my addition but maybe not, the cake ended up slightly dry. I'm really just nitpicking though; this is an excellent cake that tastes phenomenal!
