The One Chocolate Mug Cake

By  | 

There comes a time in every girls life when she needs a chocolate mug cake.

Perhaps its one of those days where you just want to curl up on the couch all day and watch bad Lifetime movies about stolen babies (ladies, you know what Im talking about). Or maybe you just ran four miles for the first time in your entire life and unless you counteract it immediately with a dessert, the universe will be thrown out of balance and implode, and the entire 2012 apocalypse will be all your fault. Or maybe its your birthday and everyone forgot so there was no cake. Okay, sorry, that last one was kind of depressing. Anyway, my point is, sometimes you just need a bite of cake to make things right. Just a bite.

I was never a fan of mug cakes because all of the versions Ive tried have turned out rubbery and just not at all delightful. Until I found this recipe, which for me is the one. This is why I like it:

  • Its not very sweet. (If you want it sweeter, add more sugar or some chocolate chips.)
  • Its small. Other recipes Ive tried have just been too big and they make me feel like I just over indulged. This one is just a few, rich, delightful bites.
  • There is no egg. I find that eggs make mug cakes rubbery or spongey and they also mean that you cant scale the recipe in size. If you want a small cake, you cant just split an egg in half, right?
  • There are a lot of variations. Add chocolate chips, use nutella, jam, or caramel sauce in place of the peanut butter, vegan-ize it by using soy milk in place of cows milk… lots of options.

Dont be tempted to leave out the peanut butter (or jam, or whatever you drop in the center) because it helps keep the cake moist and rich. It simply wouldnt be the same without it.

So, shout out to Jessie at Made From Scratch for experimenting with mug cakes until finding this perfect mix. You just saved the universe from imploding!

peanut butterDrop a dollop of peanut butter down into the center and press it into the batter (I should have pushed this in a little more, you want the PB to be mostly covered in batter).
