How to Make It
Preheat oven to 350°F.
Spread nuts on a small rimmed baking sheet. Bake at 350°F until lightly toasted, about 10 minutes, stirring once. Cool 10 minutes. Rub off skins. Reserve 20 hazelnuts. Pulse remaining hazelnuts in a food processor until finely chopped; transfer chopped nuts to a small bowl.
Pulse dates in food processor until almost pastelike. Add almond butter, cocoa, 2 tablespoons water, vanilla, and salt; process until well combined. Turn mixture out into a bowl; divide into 20 equal portions. Roll each portion around 1 whole hazelnut to form a ball. (Mixture will be oily.) Roll each brownie ball in chopped hazelnuts to coat. Chill until firm, about 30 minutes.
