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.

This recipe literally changed my life. OMG, a 1 minute dessert combining my 2 favorite loves - peanut butter and chocolate!? Sign me up! God bless you Cassie.
making this for dessert tonight 😀 woot woot!
Are you going to get the "Pin It" on your recipes anytime soon? I LOVE this one. I made it last night and it was fan-ta-bulous!
It's up to Recipage if they want to add Pin It or not, but you can have your own "Pin It" bar on your browser and that's what I use! Just go to About > Pin It Button. 🙂
Just tried this. Delish! Adding some oatmeal next time. 🙂
I made the cake..yum! But for the frosting/glaze, I used 1/2 teaspoon melted butter, 1/4 vanilla extract, 1 TB powdered sugar, 2 teaspoons milk and 1 teaspoon strawberry preserves!! PB and J!!!!!!!!!
I made this vegan with orgran egg replacer (mix the powder directly in with the dry ingredients) and soy milk, and brown rice syrup instead of the brown sugar. Delicious!
I have been making small cakes similar to this since I was 14 at home for the summer and it was just me and my 14yr old step brother during the day. We were left to our own devices to fix our own food but told to not use the stove.
Haven't tried this yet, but it sounds great!
Could you make this with melting peanut butter and adding chocolate chips, we don't have any eggs. (weird i know!!)
I believe the egg is important in the chemistry of the cake to help it rise. Other folks have said that a flax egg or chia seed egg works in substitution.
thanks, today my mom finally got to go to the store! yay! and as soon as she was back I made this!! Mine was kinda like cake at the bottom, and really peanut buttery at the top. Is it supposed to be like this? It tasted great though!! Only complaint is that it took longer than a minute! haha BUT I'm alright with that! haha
hi!
i know you dont need this now but others might find this helpful:
baking without egg is possible. my sister is allergic to egg so we substitute egg with applesuace. for every egg do one large teaspoon of applesuace. it does sound weird but it works!
It's great vegan option, too. Others that work well are silken tofu, flax seed, or soy flour for binding.
Oh gotta try this...Just happen to have all the ingredients too..thank you
Thank you for sharing. As soon as I read the recipe I had to go and make it. It will definitely be posted on my fridge for future reference.
Wow ... nice recipe. We can dance now... 🙂
can you substitute the brown sugar for sweetener and the flour for whole wheat?
Yes on the whole wheat, probably so for the sweetener. But I don't use artificial sweeteners, so I can't tell you for sure. 🙂 If you read through the comments, I believe some people have tried it.
this is insane!!! Just made it and it was delicious! and huge too... I added a few Ghirardelli chocolate chips and voila a perfect dessert was made. Topped with some whipped cream. Yum!
Thanks a lot! This is a keeper!
Just tried it because my fiance was whining that we had no more peanut butter fudge. As others said, trust the recipe and don't over zap. He LOVED it! It's too easy. Definitely hungry soldier approved!
I made mine in the oven at 350 and it took about 20 minutes. I put it in a mug and it really is like a cupcake serving or more. Really yummy!
I just made this for my husband and I this evening, he said it was like a big cookie 🙂 One more happy customer!
Awesome, Claire! Glad you liked it. 🙂
Just tried this. Thought I was missing an ingredient or something. Did not come out good at all. Too spongy and no flavor. I'll try the nutella one next time 🙂
Try using just half an egg. It's spongy because there's a whole egg in what is equal to about two cupcakes. Or, I've heard you can also 1 tbsp sub greek yogurt.
has anyone come up with the time it takes in the oven please? im dying to try this. thanks for the great recipe!
This is great! Absolutely brilliant! I am totally going to try this. How did you come to figure out how to do this?
This a really great! It's delicious and speedy and perfect for a last minute cake!
