Gather the ingredients. Preheat the oven to 325°F (165°C). Line 2 cookie sheets with foil; lightly grease the foil with cooking spray.

Place almond paste and white sugar in a food processor; blend until combined. Add confectioners' sugar and 2 egg whites; blend until smooth.

Whisk remaining 2 egg whites in a small bowl. Place pine nuts on a shallow plate.

With lightly floured hands, roll dough into 1-inch balls. Coat balls in egg whites, shaking off excess, then roll in pine nuts, pressing lightly to stick.

Arrange balls on cookie sheets, and flatten slightly to form a 1 ½-inch round.
