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.

Just made some for my family and I. Had to multiply all the portions by 4 for everyone. They Turned out AMAZING! I added vanilla and almond extracts to the frosting, and it was perfect. That hit the spot just perfectly! Thanks for a great recipe 😀
Holy guacamole! dude, you are doing the lords work. Little peanut butter cakes, really!?! I just put you on my bookmark hun. I won't try this recipe until next week, because I have to watch the amount of goodies I eat per week, but once I do eat these cakes I will comment here about it.
this website is soooo bookmarked.
Delicious and so easy!
Thank you!
Thank you very much for this.
My wife is not feeling very happy tonight (lots of study) and it put a smile on her face again.
I added 1tbs of strawberry jam to the mix as well (I did not have enough peanut butter).
A scoop of vanilla ice cream with a very small amount of melted choc and it went down a treat.
Putting cointreau in this! Double double yum!
oh, and by the way.
Pantry made need to up to the peanut butter supply from now on 😉
THIS IS SO IRONIC. I StumbledUpon this at 1 AM. And started reading, and that literally was EXACTLY what my night was, SYTYCD and all. I can't believe it. I googled a bunch of quick desserts, and this one sounds SO MUCH BETTER. Damn you, Internets.
Wow! This sounds so ooey gooey quick and easy! I am to have this for dessert tonight. I'd like to thank you for sharing and I'd like to thank stumpbleupon because without 'em I had never known this existed so Thanks!
ohmygosh this has absolutely made my day. i stumbled to this recipe and immediately had to try it!!! ahhh it fascinated me how easy it was, and i will forsure be making it again soon! thanks so much for sharing!!
Similar to the life saving mug cake-- but better!
Having had the experience of microwaving a mug full cake batter for a quick dessert, I just used a mug instead of a ramekin! Works just as well.
Love this recipe, desperate times call for desperate measures no more!
O.M.G. I'm going to try this right now...Pardon me for talking with my mouth full...Thith ith wery nithe...I'm not an innovator so I followed your original recipe, and topped the finished cake with a teaspoon of Nutella...No ramekin, but my large coffee mug served very well...I used non-stick spray. I'm not sure I'd make it unless I was reeaally desperate for some little sweetie, but it certainly more than serves the purpose. Thank you and feel free to experiment anytime.
Unreal....used diet caramel sauce instead of icing. Thanks. This is quick enough for me to mix at home and cook up at work for these cold winter days.
YUM! Sounds delicious! Glad you liked it. 🙂
just made this to surprise my little sister while she was watching a movie..she LOVED it!!! Drizzled with nutella is definitely a must! Great recipe, super easy! Thanks for sharing 🙂
Yay! So glad she liked it. And next time, I'll definitely drizzle with Nutella. 😀
wow this is the first recipe i had made on my own at home. i am not much of a peanut butter fan and i couldnt make the frosting for i had no powdered sugar but this is awesome! i love how fluffly it is! thank you so much!
Yay! So glad it turned out well. 🙂
I tried it with protein powder instead of flour. It was crumbly, tasty and packed full of protein. A quick and easy guilt-free pleasure 🙂
Great idea! Glad the protein powder worked. 😀
I don't have brown sugar...Will regular sugar or honey do?
Hmmm. I'm not sure. I'm inclined to think the honey is to liquidy and the regular sugar will make it too dry or cookie-like. But try it out an let me know!
I found this recipe a while ago and finally have the brown sugar to make it! i also had a reeses peanut butter cup calling my name so i combined the two and it was delicious! I just put the cup ontop of my batter and it sunk slight while baking and got all melty and gooey. delicious!
Mmmmm! Now that sounds delicious!
I tried this in the microwave; it was great. Will this same list of ingredients work in the oven. I'm thinking about featuring it on my Big Green Egg actually, indirect...thoughts?
I think it should work fine, I'm just not sure on the timing, you'd have to watch it closely the first time to figure it out. Good luck!
I just found this on stumbleuppon and I had a need to try it. WONDERFUL! I love this cake so much, and so do my little cousins! I added a little extra brown sugar and some coco powder and it turned out amazing! Thank you so much for posting this, I will deffently make this for years to come!
So glad you liked it! YUM on the chocolate version!
These are great but CALORIE BOMB!!! i didnt put it into an analyzer but in my head i got to 400 easy. if you are trying to watch your waist line... dont ever make one of these. i used to make chocolate cake in a cup things and they become QUITE addictive because of how easy they are. OH also, you can usually nix the egg and just toss in a little tiny bit of yogurt and more baking powder.
I just stumbled upon this lovely entry. I must say, this is something I'll have to try.
