In a bowl, whisk together the flour, sugar, and salt. Rub in the cold butter until crumbly. Add ice water one tablespoon at a time, kneading just until a smooth, stiff dough forms. Wrap and chill 15 minutes.
Preheat the air fryer to 300°F.
Divide the chilled dough in half. Roll each into a circle and press into a mini pie plate, trimming any overhang. Line each with foil and fill with pie weights or dry rice.
Air fry the weighted crusts 8–10 minutes. Remove the foil and weights, prick the base with a fork, and cook another 3–5 minutes until set.
Meanwhile, whisk all the filling ingredients together until smooth.
Pour the filling into the pre-baked crusts, leaving about ¼ inch below the rim.
Increase the air fryer to 350°F and bake 8–10 minutes, until the filling is set and no longer jiggly. Tent with foil if browning too quickly.
Cool to room temperature, then refrigerate at least 2 hours to set. Serve with whipped cream or ice cream.
