One Minute Peanut Butter Cake

Picture this scene: it's 8:30 in the evening. The sky is just starting to get dark outside your living room window. You ate a delicious, healthy and veggie-filled dinner a few hours ago and now you are ready to sit down to the most recent episode of So You Think You Can Dance and dive into a decadent plate of dessert.

Oh wait, you have no dessert.

No chocolate, no cookies, no ice cream, no cake, no pie, not even a Jordan almond. What's a girl to do?

Well she's to go to her microwave.

You can make a delicious, fluffy, moist peanut butter cake in your microwave in about one minute (30 seconds mixing, 30 seconds zapping). It even has frosting (as any good cake does). This is portion control and convenience at their greatest.

The options are also pretty endless. Toss in a tablespoon of chocolate chips for a chocolatey and gooey kick (like I did) or a few peanuts for an earthy crunch. Or leave it plain for the quickest and easiest route to dessert o'clock.

  1. This was awesome! Just the thing i needed to get my mind off things 😀 i made one with just peanut butter and another with one tb peanutbutter and a tb of nutella, had to microwave it a little bit longer but it was worth it 😀

  2. Gotta check in here and say I LOVE this! I make it a couple times a week...yep, busted, lol. Also want to clarify, bc I see it in the picture but not in your recipe ingredients: it is wayyy too sweet if made w/ regular peanut butter. I would suggest either changing that or omitting the sugar if regular peanut butter is used.

      1. I made it with regular peanut butter (Jif creamy) and it wasn't too sweet for me (I typically don't like things too sweet). It's really tasty!

        I want to try it with crunchy peanut butter now!

  3. I came across this recipe on foodgawker and had to try it. It turned it better than I expected and was super easy. I added chocolate chips and marshmallows. Amazing!

  4. I stumbled upon this recipe and immediately needed to make it! My husband found it easy enough so he volunteered to make it! THANK YOU for creating a delicious dessert that my husband can make!!!

  5. I used Rye Flour instead of normal flour (no normal flour in the house) and normal sugar instead of brown sugar, and it worked just fine. I had to microwave it for one minute instead though. But one thing that happened was that the peanut butter sunk to the bottom of the bowl, and when I removed the cake from the bowl it lost most of its peanut butter.

    1. Sounds like you didn't quite mix it up enough. You want it to be one, whisked together batter before zapping it.

  6. I've already made this three times this week. I even added a layer of finely sliced bananas in the middle, chocolate chips in the mix and instead of the frosting I added a thin layer of nutella with 10 seconds left on the timer so it seeped into the cake juuust the right gooey amount.

    Thanks!

  7. I just made this for my supper tonight (that's right.. not just dessert). Added crushed up peanut m&ms to the cake and mint chocolate chip ice cream and chocolate syrup on top... delicious! (the workouts and better diet are starting tomorrow).

  8. oh my gosh! it looks so yummy!i will try the 90-second nutella cake thingy as well!thanks for sharing! 😀

  9. Hi, I made it and it worked perfectly! My mom has this gross whole grain flour in the house so that threw off the flavor a tad but for the icing since im not a huge fan of the taste originally i simply added about a teaspoon and a half of peanut-butter and microwaved it for 10 seconds and stirred it and put it on the cake! Delicious!

  10. Cassie - I was so skeptical after reading this, but I just made this and it was INCREDIBLE! I posted about it on my own blog & linked back to yours, I'd love for you to check it out!

    Thanks so much!

  11. I was sitting here craving something sweet and saw this pop up on Pinterest. I have Celiac Disease so I took a gamble and made this with Gluten Free flour and it came out perfectly. Thank you!

      1. I also have Celiac Disease. I found this recipe and made a few changes. I used multipurpose Gluten Free flour. I used chunkie pb. The recipe called for a heaping TB. I used level Tbls of PB and added a bit of cocoa. It turned out great! Thanks for the recipe!

  12. I read this, made it and ate it all within five minutes! But seriously stop at 30 seconds because it only looks like it isn't cooked through. Trust me, it is.

  13. thanks Cassie. this was my first time to bake and thank heavens i stumbled upon your site.

    here's how I did my version of your recipe.

    http://mytwistedrecipes.blogspot.com/2011/08/one-minute-peanut-butter-cake-adapted.html

    again, thank you 🙂

  14. I made this with 1/2 banana instead of an egg (I am vegan) and microwaved for 45 seconds. De-lish!
    (When I am not able to use up bananas before they get too ripe, I place them in the freezer. When I need an egg or 2, I thaw the banana and it comes out of the peel like toothpaste. Works for all baking; adds richness and sweetness.)

    1. Thank you for adding this! It's late at night. I am desperate for cakey goodness and no eggs! I have a freezer full of eggs. THANK YOU!

  15. this looks so delicious!! And relatively healthy. I'm most definitely going to give this a go when I get home 🙂

  16. I want to try this recipe out, but unfortunately I don't have brown sugar. Any ideas on what I could use to replace it, or no? Thanks. c:
