In Germany, the no-bake dessert Kalter Hund—also known as hedgehog slice—has cult status. At Berlin’s Alte Backstube café, Uwe Marchlowitz handcrafts this chocolate-biscuit treat weekly using cocoa, almond meal, coconut oil, and layers of crackers. The name “cold dog” likely comes from mine carts resembling loaf pans. With over 10 variations, the classic remains the bestseller, evoking sweet childhood memories.
