This simple chocolate sheet cake is a staple in many Swedish households. You start with a moist chocolate base, let it cool, then poke holes across the top so the delicious mocha icing can seep in. Finish with a layer of unsweetened shredded coconut (it has to be unsweetened) and cut it into squares. It’s almost like our version of a brownie here in the U.S., and is sold at bake sales, brought to school parties, and shared after games.
