These layered squares are more “sophisticated” than my usual lineup of Christmas candy, but they’re also very popular. People love the pairing of chocolate and hazelnuts. —Virginia Sauer, Wantagh, New York
1Line an 8-in. square dish with foil. Place hazelnuts and oil in a food processor; cover and process until mixture forms a paste.
