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. Just tried some, baked it in the same bowl I whisked everything in. Sticky, but delish. No icing for me this time, maybe next. Good job!

        1. If you don't like it stick, you can microwave for a few seconds longer, but be warned, it gets very dry, very fast. Glad you liked it! 😀

  1. Well that sounded too easy. Im sure to try this out on the weekend and will try to add my own sweet ingredients. Thank you for this simple recipe.

    1. Hmm, well you can always eat the cake without the glaze, although I tend to think it is too dry that way. Do you have any chocolate sauce to drizzle on? Or a scoop of ice cream would work well too. If all else fails, maybe some maple syrup or honey.

      1. mmm...i tried the jam idea and it is delicious!!! i had all theingredients for the icing but i just couldnt pass up the jamidea!!

  2. LOVED this! Didn't have any chocolate chips in the house so i mashed up some bananas and broke up a few pieces of cappucino flavored dark chocolate and it was amazing! thank you so much!

  3. I only have 30 seconds to post this (my cake is microwaving) but I have to say that this recipe is PURE GENIUS. Thank you!!!!! (PS - want to make this lower calorie? Use PB2 from Bell Plantation. It is REAL peanut butter but only 52 calories for 2T)

  4. This sounds delicious but I don't have a microwave...do you know if and how I could cook it in the oven?

    1. Not entirely sure (another commenter is going to test it out and report back) but a wild guess is between 10-15 minutes in a 350° oven. But do the toothpick test often because it might be much less than that or much more.

  5. OH MAH GAWD. this is amazing!! i had everything except for the flour, so i just used pancake mix. hahaha but it still came out DELICIOUS!! I LOVE THIS RECIPE.

  6. I love portion control recipes like this! But I don't have a microwave! How long would it take to bake in an oven at 350 degrees?

    1. Hmmm! Just a rough guess would be 10-15 minutes, but I really have no idea. I'd put it in and then do the toothpick test every few minutes or so and then you'll know for the future. Let me know the results, if you don't mind, and I'll add 'em to the recipe!

    1. One of the other commenters is going to try it in the oven and report back on how much time it takes. 😀

  7. Sadly, the recipe needs some tweaking to work with Nutella instead of peanut butter. And I only had 2 eggs, so I wasn't able to do much tweaking.

    It wasn't pretty, but it was still tasty.

    1. Oh bummer! What happened? Was the nutella too runny? Maybe add a bit more flour? They aren't pretty cakes to begin with. 😛

  8. I love the idea that it is small and portioned controlled... so it's not so easy to over indulge! Thanks for sharing!
    I am sharing this one with my team on Spark!

    1. If I'm feeling particularly controlled, I'll pour the batter into two smaller ramekins and split the serving with Babyface. That makes it out to be only about a 200 calorie treat.

  9. This is such a goo idea! Who doesn't love peanut butter, too.

    I often find myself in this dilemma - looking for a sweet morsel after dinner and these are all things you likely would have in your kitchen. Making it soon. Thanks!!

  10. So I was just sitting here, feeling sorry for myself that I had nothing for dessert and this post showed up in my reader. I didn't have any peanut butter, but I had a few squeeze packets of Justin's Almond Butter and they were fantastic!

    Yay for quick desserts!

    1. I had a sweet tooth but didn't feel like firing up the oven. Tried this quick recipe. The frosting was great (added a little vanilla and nutmeg for taste) but the cake was a little bland but for a few minutes instead of an hour,and less clean up, it was good enough to satisfy that sweet tooth!
      Thanks!!

  11. I just tried it! No sweets in the house, and neither Mr. B nor I feel like leaving for the grocery store tonight...and what do you know, I actually DO have all of these ingredients (including chocolate chips, which is a rare miracle). Cake came together so easy and the taste is just right to satisfy an evening carb craving. I DID not follow the microwave instructions and nuked my cakes for 50 seconds instead of 30--the texture (and I) suffered for my mistake.

    1. It gets dry QUICK, for sure. If anything, you want to undercook it slightly. Hope you try it again!

      1. I have tried your cooking and buying bread is not in my budget now. Breakfast with my family is more enjoyable than ever, my family is on table together again.
        Thank you
