I made you a mug cake.

Actually, to be quite honest, the mug cake practically made itself. Yeah, it’s that easy.


This is one of those life-changing recipes. This is that recipe that (of course) came about entirely by accident and then became a staple in my diet. This is the most dramatic intro to a mug cake you’ve ever read.

No, but seriously. This cake/brownie/chocolate amazingness is sugar-free, gluten-free, and dairy-free. So what’s in it?

Literally three things (six, if you’re feeling fiesty and want to throw in some chocolate chips and/or chopped nuts and/or coconut): a banana, some cocoa powder, and some PB2.

I’m no stranger to the chocolate and peanut butter combination. And I love me some PB2. If you’re new, it’s powdered peanut butter: healthy, delicious, and perfect in this recipe.

When you blend up a banana with cocoa powder and PB2 and then stick it in the microwave for under a minute, something kind of amazing happens: the cocoa powder and powdered peanut butter act as a binding substance (like flour!) and the banana caramelizes and sweetens the mixture. What you end up with is a moist and unbelievably easy cake.

Beyond being ridiculous easy to make, this cake is remarkably healthy. Cocoa powder is essentially the healthy version of chocolate, and same goes for PB with peanut butter. And it’s not like bananas are exactly junk food.

I enjoy this mug cake alongside a tall glass of almond milk. It’s perfect for satisfying chocolate cravings and is seriously guilt-free!

Healthy January was never easier!

    Wow — with all its simplicity this looks absolutely decadent! I’ve got some powdered peanut butter in my cupboard right now {that I absolutely love too, btw} and I can’t believe I haven’t tried it out in a mug cake yet! Thanks for the awesome idea 🙂

    P.S. Although I think PB2 is great, I actually use a different brand of pb powder you might want to check out sometime — it’s called Just Great Stuff and it’s organic and uses sea salt and coconut sugar. Same specs as PB2 otherwise.

    How is it that bananas, chocolate and peanut butter are so amazing? Each alone, they transform any recipe… put them together and LOOK what they can do! Thank you for your creative, easy, vegan recipe, Medha! Oh, love that action shot at the top! 😀

    OK, if this decadent looking mug cake is this easy to make, I’m in serious trouble! I don’t have PB2, but I think I’ll have to try it with peanut butter. Like right now!

    Okay, I’m going to be straight with you. I have no clue what you just wrote up there. I tried to read it. I really did, but then you put this obscenely delicious food porn up and all the words blended together and got all blurry. Is it legal to marry food yet?
