Peanut Butter Chocolate Cake

Peanut Butter Chocolate Cake

I’ve been craving good Chocolate cake for months now. Not the kind you buy at the Home Industry that’s already kind of dry but you eat it anyway. No, I wanted moist, rich, insanely chocolatey Chocolate Cake. And then a week ago I had this intense craving for Peanut-butter and I thought, why not put the two together. I have really great Chocolate Cake recipes but I wanted to try something a bit different and whilst browsing through Tastespotting I saw this amazing cake by Foodess.  Now I’m sure you’ll agree with me that, THAT cake, is probably the best looking Chocolate Cake I’ve ever seen.

I fell inlove instantly and just knew that would be the recipe I would be using, with the added addition of peanut-butter, of course. I also baked my cake for just slightly longer because of this addition and therefore mine isn’t quite as fudgy as Foodess’.

I know many of my readers prefer using weight measurements instead of cups and whilst baking this cake I measured out all of Foodess’ ingredients but somehow my notes went missing. I’ll re-make the cake this week and then add those measurements in, for your convenience.

I don’t know about you, but the frosting really does make the cake for me. BUT, too much frosting ruins it quite easily, so I really wanted to have just the right amount of frosting on this delicious cake but I knew I wanted it to be the most delicious frosting I could think of. I played around with quite a few things for about an hour and settled on this Peanut-butter-Chocolate-Fudge Frosting…it’s absolutely to die for and I could not stop licking the spatula…seriously! My husband started worrying that I would never let go of it. Obviously, if you have nut allergies, please don’t attempt to make this cake, but if you don’t do try it. It’s really one of the tastiest Chocolate Cakes I’ve ever baked and I’ll never let go of this frosting recipe!

    I made this twice and today’s attempt was even better!! Two of my favourites rolled into one. It was amazing. I added some Willy’s Black Indonesian chocolate to the frosting and used only cream. And espresso instead of regular coffee in the batter just made it even better. Thank you for a brilliant recipe. This is definitely a keeper.

      Shakira, I’m so glad you liked it! I’m sure the espresso made it just so much better!

    I made this cake for my boyfriend’s birthday – WOW! Mine sunk a leetle in the middle, but it tastes AH-mazing. I only baked mine for about 35 minutes and I have 240mm tins not 220mm, so it was a little flat – But OH MY GOODNESS. It has a very fudgey, brownie-like texture and is not overly sweet. I haven’t baked a cake in about 5 years (when my last cake turned out to be a charcoalate cake due to forgetting it in the oven, whoops) but this has renewed my interest in baking.

    Thanks for this i will baking this week end buttermilk in cake i love it and yummy to see and waiting to taste it .

    • Ally_R

      Sarah Jo : Buttermilk makes such a huge difference in keeping the cake moist! I hope you’ll like it.

      Angie : It could be that you’re cake sunk in the middle due to taking it out of the oven suddenly, usually a quick change of temperature can make that happen and also that it was probably not cooked properly in the middle. But I’m glad you liked it non-the-less and I hope you will continue baking! 🙂

    Found this recipe by “mistake” whilst Googling another & all I can say is, best mistake I ever made! This cake is really moist, heavy & deliciously chocolatey. Word of advice though, make sure your baking tins are deep enough. Mine were too shallow & my batter ran over the sides. Gives me another reason to bake it again!

    I am from SA but is currently working in Chillilabombwe Zambia. Craved for chocolate cake, then I saw this recipe on the web and decided to bake it. With some advise from my wife down in SA and without proper measuring equipment I baked it. Successfull and very nice !

  • Chrissy

    I saw your beautiful cake on Tastespotting. Then I check out your blog and you’ve got an entire section devoted to risotto! Yum! I just may have to figure out some temperature conversions so I can try some of these.

    • Ally_R

      Chrissy: How can I NOT have an entire section devoted to Risotto? I absolutely LOVE the stuff! 🙂 If you hover over the temperature it should bring up a conversion for you.

      Nicola, it really was! 🙂

  • Rosemary

    Using buttermilk in cakes always insures a moist texture – I am a convert to buttermilk for cakes. The combination of chocolate and peanuts is a definite winner.

    • Ally_R

      I also LOVE buttermilk in cakes..same with sour cream. And chocolate and peanuts is such a comforting combo for me so this cake is just heaven for me!
