Kladdkaka is the queen of swedish cakes and is basically a chocolate mud cake with crisp exterior and a gooey, dense chocolate interior. A brownie somebody could say, but the swedish Kladdkaka has more sugar than a brownie and no baking powder or any other leavening agent.
The result is a dense cake that is intentionally left a little runny, so the middle of the cake oozes out when cut!
As with any cake recipe, Kladdkaka can take some nice variations, making it a nice surprise for everybody. Below is the straight swedish Kladdkaka recipe and at the end a couple of tips and tricks as usually :-)
