Gather all ingredients.

Prepare the Crust: Pulse waffle cones, pistachios, and sugar in a food processor until mixture is finely ground, about 20 (1-second) pulses. Add butter, and pulse until mixture holds together when squeezed, stopping to scrape down sides as needed.

Lightly coat a 9-inch deep-dish pie plate with cooking spray, and transfer waffle cone mixture to prepared pie plate, pressing evenly into bottom and up sides of pie plate. Freeze Crust, uncovered, until set, about 15 minutes.

Meanwhile, prepare the Filling: Finely chop pistachios and transfer to a medium bowl. Add ricotta, mascarpone, powdered sugar, chocolate chips, orange zest, vanilla, and salt. Stir until combined.

Beat heavy cream with an electric mixer on medium-high speed until medium peaks form, 2 to 3 minutes. Spoon whipped cream into ricotta mixture and gently fold until just combined.

Spoon ricotta mixture into prepared crust and spread in an even layer. Cover with plastic wrap and refrigerate until set, at least 4 hours or up to 8 hours.
