Fill a shallow dish or plate with warm water. Dip one rice paper sheet into the water for about 10 seconds until soft and pliable, then transfer to a clean surface.
Sprinkle about 1 tablespoon of graham cracker crumbs in the center. Top with a few spoonfuls of chopped fruit and drizzle with about ½ tablespoon of peanut butter.
Fold the sides of the rice paper over the filling, then roll it up like a burrito to seal. Repeat with the remaining ingredients to make 10 dumplings.
Lightly spray each dumpling with oil and place in the air fryer basket in a single layer. Air fry at 400°F for 5 to 7 minutes, or until golden and crispy, flipping once halfway through if needed.
Dust with powdered sugar just before serving. Enjoy warm and gooey.
