WARNING: this is where diets come to die… in a rich, fudgy pool of decadent melty chocolate and peanut butter enveloped in a thick, fluffy cake.

I’m just saying.

Sometimes you just need chocolate cake rightnowrightnow. Right?

And when that craving strikes, you don’t want spend the time (and dirty dishes) slaving away over a full sized cake. And you really don’t want an entire cake sitting around, tempting you for days after the craving has passed (because, omg, I can eat an entire chocolate cake in one afternoon without even really wanting to– please tell me that’s not just me?!).

Enter: mug cakes. They are simple and easy, warm and fresh, and they’re ready RIGHT NOW.

It’s brilliant.

These little cakes are a little different from typical molten lava cakes. Because instead of slightly underbaking the cakes to create the lava center, I’m actually adding a brick of chocolate and a teaspoon of creamy peanut butter (!!!!!) to get all warm and melty in the center of this cake.

I prefer this method over the underbaking for a couple of reasons.

One, for some reason the uncooked cake batter “lava” has always kind of weirded me out. I don’t know why– it’s not like I don’t lick the bowl after I make a cake! But something about uncooked batter masquerading as melted chocolate… it just never seemed right to me. So there’s that.

Second of all… since we are microwaving these cakes rather than baking them, the heating method is kind of wonky. We’re dealing with cooking time in terms of seconds rather than minutes, so it’s nearly impossible to be as precise as we would need to be in underbaking the cake the exactly right amount of time. By using actual chocolate in the center, we eliminate the headache of trying to figure out how to keep the center unbaked while nuking the rest of the cake just enough. Fabulous.

I desperately wish that I had some ice cream on hand when I was photographing this. Wouldn’t a big scoop of vanilla plopped in this warm mug of melted chocolate and peanut butter just be divine?

All I had at the time was whipped cream, and that was pretty good too 🙂

Just a few simple ingredients and about 60 seconds is all you have standing between you and this cake. Enjoy!!
