The only reason I'm giving this amazing recipe 4 stars is because when i stirred the 2 eggs into the melted butter, the egg sort of cooked into little tiny chunks. This did not make the cake taste bad by any means, but it left the chunks in the final product, which reduced the creamy and smooth texture. I did make one substitution - I used coconut butter for the batter in place of butter. It turned out so good! I brought half of the pan to work and everyone LOVED it! I'll be making this again - but I will try mixing the eggs into the batter at the same time the butter is mixed into the flour.

We loved it!

Rich & delicious! The peanut butter layer and chocolate icing taste like peanut butter cups. The cake was good, but somewhat overpowered by the volume and sweetness of the icing.

I have never made a cake this way before. It was kinda nice not having to drag out the mixer and all its parts. I microwaved the peanut butter and it poured right on. Then I put it in the fridge so the peanut butter would firm up. The result was a pretty and smooth layer. The fudge layer went on like a breeze!! This makes a lot of portions. (portion size should be small because it is so dense) I cut remaining pieces and wrapped them individually in saran wrap and put in a freezer bag. This way when anyone needs to get their "chocolate fix," they have a homemade goody from Mommy waiting!!

This was a good recipe, but as others stated, it is rich. I am always looking for ways to use leftover buttermilk, and this worked out well. Thank you.

WOW! I made this for a friend's birthday (he's a peanut butter freak) and EVERYONE was raving about it. It was a huge hit. You MUST like fudge to enjoy this cake. It's thick and heavy and ohhh so good. I made it just as written and it came out perfectly. I won't have a choice but to make this again, as everyone has requested it for their birthdays!

I was going to wait to review this until I had made it in the context that was intended, however, I have gotten such rave reviews, I decided to review it now. I really enjoyed making this "cake" (more like a brownie actually, the process of melting the butter and adding the cocoa powder is a technique used when making brownies from scratch, don't forget to temper the eggs, scrambled eggs and chocolate yuck!)I made a few minor changes to the initial recipe in I used 1/2C Whole Wheat flour and 1/2C oats that I had ground in the blender. It was a fairly simple dessert to make, though, it took a lot longer to bake, I will chalk that up to the fact that we were having torrential downpours that day. Well, that was all lovely and whatnot, but I got impatient and tried to flip the pan before the cake had cooled well enough.... Not a good plan.. The cake was RUINED. I am not one to let a perfectly good, if not completely decimated cake go to waste, well, I spread the peanut butter on what was left of the cake and I went to the grocery store and got some chocolate pudding and some cool whip. I came home and made a trifle with the mess, I used chocolate pudding, chocolate cool whip and plain cool whip. I took this concoction to work (I am making the Peanut Butter Fudge Cake for my family reunion this weekend) and I was told by my colleagues that this is the best thing I have ever made, and I can bring my mistakes in anytime!!! I can't wait to try the actual recipe this weekend!!!

THIS IS THE BEST THING SINCE PEANUT BUTTER AND JELLY.DIDN'T CHANGE A THING.CAUTION....WILL NEED A TALL GLASS OF MILK.

This is fudge on top of a very sweet cake, It was just too sweet overall for us.

This is a wonderful recipe. I added a lot more peanut butter to the recipe. It does take a while to make, but it's worth it. My in-laws request this cake every Easter.

I was so disappointed with this recipe. The cake was dry and the icing was super thick. It was not peanut buttery enough for us. Sorry.

The cake turned out very moist. was appreciated by my whole family. My sister couldn't believe it was homemade. Thanks for the recipe.

Loved it !!!!!

Very good! Pretty simple to make, lasts a long time because its so rich. And something that everyone likes! Thanks!

Everyone at work raved about this cake. Cake part was more like a brownie but with the PB and frosting it went very well together. Will definitely make this again.

The cake came out really dry and tasteless, but after I added the peanut butter and icing, it made up for the taste. After it was put away for the night, the toppings softened up the cake and made it nice and moist. The fudge-like topping is rich, but not too sweet. I might make this again.

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, when we returned, the icing had hardened in the mixer, so I added the peanut butter directly to it and some light cream to bring it to the right consistency and voila! I will definitely make this cake many, many times, especially when I eat the last piece! Try this, you won't be disappointed.
