Chocolate cake, chocolate frosting, but with what a difference. Peanut butter is the magic ingredient. It is spread between the cake and the frosting.

  1. This cake caused arguments in my house. "What do you mean you ate the last piece!?" arguments. It was absolutely dense, rich, and delicious. I did make a few changes. I didn't spread the peanut butter layer alone; I was mixing the icing when we got a call and had to leave the house quickly, - Read more ...
  2. This recipe was not nearly as wonderful as I thought this would be based other's recipes. My husband thought is was okay but I could have saved a lot of time by making a chocolate cake the "normal" way without all the hoopla this recipe puts you through open up a can of fudge frosting - Read more ...
  3. Excellent cake! It is very rich though, so eat in small portions. I found it was easiest to microwave the peanut butter for 30 seconds and then pour in on.
  4. This was OK. I really was expecting this to be spectacular from the other reviews I had read. My husband and I thought the frosting was WAY too sweet. Kids liked it though. There are much better recipes out there for the peanut buttery or fudgey that you crave. Sorry I won't bother with this - Read more ...
  5. I made this for a friend's birthday and it was a big hit. The peanut butter layer is what makes this cake, and no one could figure out what made it so great. Also mixing the peanut butter with a tablespoon of vegitable oil before spreading on the cake makes all the difference!
  6. Very rich and yummy cake! I love peanut butter and chocolate. I've never made a cake where you first cook the butter cocoa and eggs together on the stove so that was interesting. When I was cooking the frosting mixture at the last minute the butter separated out and looked gross and greasy but mixed - Read more ...
  7. I made this for my mom on Mother's Day. It was wonderful and my mom and grandmother both said it was the best cake they'd ever tasted. I tried to make this into a layer cake, but the icing is so thick and rich, I think it would do better in a 9x13 inch pan.
  8. This is a very good chocolate cake. It is more like a sheet cake and very moist. It is so good with the peanut butter. I added milk chocolate and peanut butter chips to the batter and it was great. I took this to a group get together and everyone loved it. I will make - Read more ...
  9. This is the best cake ever! I have made a recipe identical to this for years! If you add like 1/4 cup of peanut oil to the peanut butter it makes it easier to spread. This is a moist dense cake that freezes well. You will not be disappointed with this recipe!
