Yet another version of the Swedish favorite - chokladbollar, or chocolate balls. This is a particularly rich and delicious variety with nutella (or other hazelnut-chocolate spread) in addition to the other ingredients.
100 g butter, softened
Beat together butter, nutella and powdered sugar. Stir in the sugar, coconut flakes, oatmeal, cocoa, espresso, syrup, vanilla and salt and mix to a firm batter.
Shape into small balls, and roll in either more coconut flakes, finely chopped hazelnuts, or pearl sugar. Chill and serve cold.
