Cynthia DePersio is nuts for nuts. "I adore them, so I decided to use Italian pignoli cookies for the inspiration for this tart," she told us. The New Jersey–based pastry chef adds pulsed pine nuts to a classic French frangipane, then bakes the filling in a sandy sablé crust. "I like to pinwheel thinly sliced banana slices on top, sprinkle them with raw sugar, and brûlée," she says. We're partial to crowning our pieces with a dollop of mascarpone-boosted whipped cream.
