Microwave Mug Cakes – #3 S’mores


I’m stepping up my game in my Microwave Mug Cake series. First we had dark chocolate, then salted caramel… and now S’MORES! For those who don’t know what a S’more is, it consists of marshmallow and a layer of chocolate sandwiched between two pieces of graham cracker and roasted over a camp fire into a gooey mess. Heaven.

I am yet to find graham crackers in Australia so feel free to use any sweet biscuit (I used Arrowroot biscuits). I stumbled across a tub of Marshmallow Fluff in a city convenience store a while back and have been waiting to use it in a recipe! If you can’t find it, feel free to stick a few marshmallows on top.

I made a mess trying to ensure I had a bit of cookie, chocolate cake and marshmallow in each mouthful but boy was it tasty! (And isn’t making a mess half the fun?!)
