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.

Oh my gosh. this looks soooooo good! I love peanut butter. I cant wait to try this out! thank you so much for the idea! i love the pictures by the way.
I soooooo have to try this! Especially since all the comments are saying it is to die for! I am a student and go back to the dorms in August. Gives me time to try and if I like it then make some zip lock bags up of the dry ingredients to have on hand! I could also give as little gifts for my friends! Thanks 🙂 Oh and I stumbled upon this!
I also have a blog and trying to get it started, any advice would be loved!
Thanks!
GREAT idea on the ziploc baggies! You'll be the hit of your floor. 🙂
Have a recipe that is this easy that is like yellow/vanilla cake?
Nope, I don't have one. But I'll try working on it. 🙂
Just halfed this with my boyfriend! DELICIOUS (: Thankyou!
Perfect for sharing. 🙂
Found your site on stumble upon. Was feeling an intense sugar/sweet/something-something craving. Immediately enacted your one minute peanut butter cake emergency plan. Took me about 5 minutes. That's cool! AND I LOVED IT. Crisis averted and peace remains in the household. This will be my fall back sweet fix forever. FYI I added dominican vanilla to the powdered sugar and coconut milk and heaven was the result. I am super happy, Thanks! (and full!)
So glad you liked it! The coconut milk frosting sounds awesome. 🙂
I got SO excited when I found out one of the people I follow on tumblr had blogged about this. I tried the chocolate mug microwave cake many times and found it icky and too dry but a great idea, so i jumped at the prospect of this one.
This one is good but it had a funny dry texture on the inside when I made it, I'm thinking about adding more liquids, like some milk before it gets zapped, do you think that'll help or is that just the way microwave cakes get? (I zapped it for 30 seconds). The batter by itself before it was microwaved tasted incredible (yes I'm one of those terrible people who have to taste it beforehand, lol)
Thanks for posting this recipe though! It's inspired me to start experimenting with the microwave more 🙂
Hmmm, I think that is one of the issues with microwave cakes. Whenever I make it, it is barely cooked on the outside (even a little gooey) and dry in the middle.
Let me know if you figure out a way to get around it!
I just tried it last night and thought is was quite good!
Glad you liked it! Perfect midnight snack. 😛
You, Ms. Cassie, are a flippin' genius!
I used Almond Butter, and only had Self-Rising flour, so I omitted the baking powder. Added about a Tbls of mini chocolate chips.
Poured into a large mug...nuked for 30 + 8 + 8...Perfection! I didn't even bother with icing. Yum, yum! I'm having it for breakfast. Thank you! 🙂
This post is printed AND bookmarked!
YAY! So glad it worked for you. 😀 Happy breakfast!
You, my dear, are a saint <3 thanks for the recipe ^__^
Haha! I don't know about sainthood. 😛 I was just desperate.
This recipe was so easy and delicious! Thank you!
Glad you liked it!
Oh my! I made this tonight and it was heavenly! It was just what I needed. I used a teaspoon of nutella on top of the two tablespoons of peanut butter and chocolate chips. It was a great combo! I will be making this frequently. 🙂
YUM! The nutella sounds rockin'. 🙂
Being quite the baker myself.. I was a little hesitant to try this.. However, like most people, I needed dessert and was too lazy to bake a time consuming cake. So.. I tried this.. DELICIOUS!! Instead of the powdered sugar glaze.. I melted chocolate and drizzled that on it. I also used chunky peanut butter to give it some texture.
Genius 🙂
Melted chocolate is a great idea! YUM.
Thank you Stumble! This obviously won't win a Pillsbury bakeoff, but late on a Saturday night, this worked like a champ! Completely surprised! Will try different toppings, probably chocolate to make a Reese's cake.
MMMM! Reese's cake! Genius!
this is actually a very reasonably good tasting cake, considering its method and level of ease. it actually tasted like cake! i microwaved it for 40 sec though i think next time i'll do 30 sec. i'll also be interested in adding cocoa to this to make it an easy chocolate cake.
It isn't going to win any blue ribbons, but it will definitely do the trick! 🙂
I didn't have any baking powder so I had to substitute with pancake mix as someone mentioned before for flour. Turned out pretty great although I had to microwave a little longer (not sure but it might just be due to crappy microwave) I mixed some cinnamon, vanilla, and nutmeg into the glaze- delicious 🙂 awesome idea.
MMMM! Your glaze sounds awesome. 🙂
I tried this, substituting the peanut butter for nutella and it turned out beaut when served with fresh cream or ice cream! Like brownies in a few minutes! <3
The ice cream idea is genius! YUM!
This seems amazing! But can I make it with out the peanut butter becuase my sons allergic? It would really help out! Thanks!
You could try other kinds of nut butters (almond, sunflower, coconut, etc.) but I've never tested it. If you try it, let me know!
As I sit here stumbling, with an 8 month old laid asleep, across my lap, I think about HOW HUNGRY I am, and that my sweet tooth is SCREAMING at me. Then I find this, and I see that I, indeed, have EVERYTHING on this list. My mouth is watering as I type. xoxo
Put the baby aside and make yourself some cake, lady! 🙂

It WORKS! I made this successfully with these modifications:
subbed a 1/2 to a scant tbsp coconut flour for the flour
subbed a tbsp xylitol for the brown sugar
the rest was pretty much the same except I didn't do frosting, I used sugar free chocolate syrup, and I didn't have a ramekin so I did it in a microwave safe bowl. Also, mine took a minute instead of 30 seconds, but that might just be because of my microwave or the coconut flour. Very pleased with this!! I now have a dessert I can whip up super fast when I NEED something sweet. <3
Yay! Glad to hear it worked out for you. 🙂
