This is one of my favorite cake recipes given to me from a co-worker. It is the best peanut butter cake you will ever eat. The icing is like fudge.

this is a awesome peanut butter cake. i always get ask for the recipe.If the recipe calls for butter use butter or it will not set up right and don't forget all ovens are not the same so you might need to bake it longer. I have made several of these and never had a problem with any of them. This is a very moist cake. If you want more peanut butter flavor in the cake add a little more peanut butter but i think that with the peanut butter icing it is enough. bake in a cookie sheet only. Read More

I made this cake today and it was delicious! Very easy to make. I used 9" round pans & baked for 35-40 minutes (until toothpick came out clean). I added chocolate chips to one of the batters and yum yum. Both are fantastic and the cake is moist. The only trouble I had was the cake stuck to my pans even though I sprayed them with Pam. Next time I'll flour too and see if that works. Thank you for posting! Read More

OMG! this cake is the new family fave! It is so moist and delicious. I used a small jar of natural peanutbutter. I used the separated oil as the oil in the cake and it worked perfectly. Enjoy! Read More

This cake is delicious! I've made it for years . . no need to precook the ingredients in the cake, I just stir (don't even need a mixer) it all together and bake! I've always baked it at 400 for 18 minutes and it's perfect! Very quick and easy to make! Read More
