Hot Fudge Cake with Peanut Butter Sauce

Hot Fudge Cake with Peanut Butter SaucePinitHot fudge sauce on my couch, my sweatpants, and my camera.

And Bjork just informed me that I have a little leftover on my face.  #worthit

This, well, there are no words for this.  This is chocolate peanut butter perfection.  I thought I had already found chocolate peanut butter perfection, which I pretty much did.  But here comes chocolate peanut butter perfection round two, and it’s taking on a whole new level of ooey-gooey deliciousness.

Hot Fudge Cake with Peanut Butter Sauce

And guess what?  Just guess.  You will never guess what I’m about to tell you, but I want you to guess anyways.   I hate it when people do that.

Here it be: this chocolate euphoria is essentially guilt-free!  Essentially!  Like, eat it and get skinny.

I’m totally kidding and serious at the same time right now.  Just look at the stats below.

After I made this, I was feeling real good and real healthy.

But then something predictable happened.  My brain went —> chocolate —> must.have.peanut.butter.  And then I whipped up a little batch of not-guilt-free creamy dreamy peanut butter sauce.  I added a teeny tiny spoonful of said sauce to my cake.  And ever since that moment I’ve been drowning in peanut butter sauce.

Oh my wonderfulness.  This stuff is heavenly.  Which is why I did us all a favor by keeping the peanut butter sauce nutrition facts to myself, k?  Yep.

PS. I used my regular slow cooker for this recipe which is a Crock-Pot that I’ve had for the last five years. SO MUCH FOOD has come out of that thing over the life of this blog which is pretty impressive for a $28 kitchen appliance.

As I mentioned, the nutrition facts are just for the ooey gooey fudge cake.  You don’t even want to know about the sauce.

Just go eat some healthy cake covered in peanut butter sauce and all will be right with the world.

  1. Blog is the New Black says:

    Breakfast? 😉

  2. With all that I ate last week, this shouldn’t even appeal to me right now…and yet, low and behold… :-)

  3. Hot fudge anything gets me. This cake just looks amazing, especially with that awesome sauce!

  4. oh man…how impressive! yum!

  5. Healthy! Lookit, it even has protein. Psh. Practically a diet food.

  6. Looks wonderful. You’re definitely a peanut butter and chocolate combo person, huh? There’s nothing better than that!

  7. Emily @ A Cambridge Story says:

    Another crockpot wonder!! I love that this incorporates the best flavors ever (choc and PB)!

  8. This looks so warm and comforting! Drizzling a little bit of that peanut butter sauce over a healthy little portion-controlled cake is just you practicing moderation 😉 I’d be sorely tempted to eat the sauce straight off a spoon. Call it minimalism.

    • Hahaha! Thanks for the vote of confidence. But I’m sure you already know that I’ve eaten waaaay more than just one spoonful of that sauce.

  9. These look so yummy!

  10. I’m not even a fan of chocolate cake and this looks good!

    • Thanks Emily! PS. Have you tried BT McElrath’s Salty Dog Chocolate Bars (Minneapolis based company)? They will convert you to the dark side.

  11. Those look incredible! Love the pic with the sauce running down the side. Yum! I’m bookmarking this one 😀

  12. This cake looks absolutely delicious! I’m not a fan of PB (I’m weird, I know!), but I’m going to try it with ice cream :)

    xoxo, Ana

  13. Gorgeous pic – yeah! And…all around yum.

  14. How do you think of this stuff? It’s simply amazing!

    • I was actually working off of an old recipe for the cake. But the sauce… well… sometimes you just know what works. Like butter, sugar, and peanut butter. :)

  15. Wow, I want this!! The sauce looks so good!

  16. You are making me drool! Chocolate and peanut butter are my favorite. This looks fabulous. Making it in a crockpot is very interesting.

  17. Hot fudge is my weakness. I could eat it with everything. This looks so delicious! Come visit us. We have pumpkin fried rice today. And be sure to stop by on Friday and register to win a party dress from The Shabby Apple.

  18. Lisa at Dishes of Mrs. Fish says:

    Oh my goodness.
    I love everything about this cake. :)

  19. Did you just scoop it into ramekins after baking in the crock pot or is there a way to make it in the ramekins? It looks amazing and I can’t wait to try it!

    • Yep – just scooped it up and into the ramekins. It’s a little bit messy because it’s like a molten cake, so it’s better eaten from a bowl.

  20. I love that a. this is made in a crock pot, and b. that it will make me skinny!
    Really looks amazing…doesn’t get much better than chocolate and peanut butter in my book…

  21. Seriously contemplating making these right now. Like right now.

  22. I love the role reversal here! Hot fudge CAKE getting a SAUCE put on it. Very witty, not to mention it sounds delicious! Why does peanut sauce so often get left with dinner? It seems like a logical step over to dessert. Well played. Well played.

  23. Wow. I sort of want this right now, and it’s not even 7 AM yet. Plus, I can’t eat that in front of the kids because that’s what they’ll want it for breakfast too – then I’d have a trophy-winning “naughty-mom” day. . . . This is NOT going to help my recovery from Thanksgiving.
    BTW – Love the new pic in the sidebar! 😉

  24. Oh my, PURE GENIUS in a ramekin – this is my fav combo and I am craving this for breakfast right now, is that bad? :)

  25. You just made me extremely happy!

  26. Natural Noshing said just what I was thinking, “PURE GENIUS in a ramekin..”!!!

  27. Out of curiosity, how big of a crock pot did you use? I’m making this for a friend’s birthday this week and wanted to make sure I had the right size

  28. PEANUT BUTTER SAUCE…I think I could eat that all by itself. lol..thanks for sharing

  29. This looks crazy good! Wow!!

  30. I cannot believe the nutrition facts on this cake! I think it makes the peanut butter sauce more than okay…just straight necessary :)

  31. I hope this doesn’t sound dumb, but can you use the crockpot inserts when you make this? Please e-mail and let me know what you think. (Or does the cake clean-up easily?)

  32. I’m a teacher too. Do all your students tell you your famous too? he heee.

    This looks delicious!!

  33. Hi Lindsay, I found this recipe on TK tonight and want to make it. I have a smaller-sized 4 quart slow cooker. Do you think it will work for this recipe size-wise and cooking time? I’m a very novice cook and have never made a dessert in my slow cooker, so just wondering before I try it. Thanks so much!

  34. This looks delicious. Would love for you to share this with us over at

  35. Oh my gosh! I must have this! That little bit of peanut butter sauce dripping down the bowl is the ultimate food seduction. I’m drooling!

  36. Oh wow! My boyfriend’s favorite food is chocolate and peanut butter (not separately, but as a combination!) so I have to make this! Peanut butter sauce sounds absolutely incredible!

  37. Another amazing recipe! This one came just in time for a birthday party I was hosting. You’re a life saver :-)

  38. Craig McPherson says:

    You don’t include the baking temperature…….350?

    • It’s actually made in the crockpot, so I didn’t set a temperature. But if you decide to bake it in the oven I’d go for 350, checking on it every 15 minutes or so.

      • Hey you did mention that if using the oven to bake at 350 and check every 15 mins…does the toothpick need to come out clean or slightly wet??

  39. I haven’t tried this but I LOVE, LOVE, LOVE peanut butter! I am avoiding looking at the actual recipe part for fear that I will make this delectable, by the sounds of it, sauce and then end up drinking it by the batch!

    PS. Even if I never ever try this recipe, I am a happier person. You are a funny lady!! I laughed out loud a couple times. Thanks for the happy! :)

  40. Try it,

  41. This looks soooo good. Are crockpots same as ramekins?

  42. Hi,

    Love the pictures and description. Really want to make it but I don’t own a crockpot. So couldn’t bake the same cake in an oven? Would I need to make some changes in the recipe if I cook it in the oven?

  43. Hi Lindsay

    First things first, Love your sense of humour. Secondly, of course the simplicity of your recipes. I have just joined your email list. I am an amateur Blogger and your blog and tips inspire me so much.

    Just like the previous comment I’d like to know what I can use instead of a Crockpot. Maybe the oven, for how long would I need to bake the mixture.

    Greetings from Cape Town

    • Great question, Pumla. Earlier on in the comments, Lindsay suggested to another reader to bake this at 350 degrees for 15 minutes, and then check it regularly (every 5-10 minutes) thereafter until it is done. If you make this in the oven, we’d love to hear your feedback and what worked for you! :)

  44. Hi,
    I have just found your blog and cooked the skinny vegetarian lasagna for the family for dinner and everyone loved it. At only 200 calories a serve it was guilt free aswell.
    Now for dessert I made the chocolate fudge cake with peanut butter sauce and we were blown away with the taste and contentment we felt after just one of the 8 servings each.
    So much so I just couldn’t believe it was only 200 calories also so I added all the ingredients into my fitness pal and they came out as just over 300 calories per serve.
    I’m wondering how you kept it down to 200 calories??
    I’m aiming for 1200-1800 per day to loose weight so that extra 100 calories does at times make a difference.
    ps We are in Australia
