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. Hola! I’ve been following your blog for a while now
    and finally got the bravery to go ahead and give you a shout out
    from Humble Tx! Just wanted to say keep up the good work!

  2. This may seem dumb but how do you know when it’s done? The center remained wet even after a min of cooking. The wet center if touched get absorbed in the cake but you can see the imprint of wetness . If Is it supposed to be slightly wet in the center?

  3. Thank you for making a recipe that calls for the whole egg and not just part of it because I HATE separating eggs. I am going to make this asap!

  4. OMG! Was craving something sweet tonight. Didn’t want to go to the store and certainly didn’t want to end up with a whole cake that I would inevitably feel the need to completely consume. This was perfect!! I didn’t have any chocolate chips so I added some m & m’s from my kids candy jar. Heaven! So nice to eat a “whole” cake and feel no guilt!

  5. Hi Cassie – I don’t have a microwave – is it ok to cook this in the oven and what temp and time would you recommend? Thanks! Sounds great!

    1. I haven’t tried cooking in the oven, but there are a few folks the comments who have done some experimenting if you want to read their experiences. Good luck!

  6. I was looking for a peanut butter cake recipe without butter.

    I was sooo glad to find your recipe which was unbelievably quick and all the ingredients were there in my kitchen.

    Tried it and loved it. Thank you! 🙂
