Preheat your air fryer to 350°F (175°C) for a few minutes.
In a mixing bowl, combine the diced pecans, pumpkin puree, pumpkin pie spice, granulated sugar, and melted unsalted butter. Mix these ingredients until well combined.
Take each biscuit from the package and flatten it using your hands or a rolling pin. You want them to be about 1/4 inch thick.
Place a spoonful of the pumpkin mixture onto the center of each flattened biscuit.
Fold the biscuit dough over the filling to create a half-moon shape, sealing the edges by pressing with a fork. Ensure that the fritters are well-sealed to prevent the filling from leaking out during cooking.
Lightly grease the air fryer basket with cooking spray to prevent sticking.
Place the pumpkin-filled fritters in a single layer in the air fryer basket, making sure they are not touching each other. You may need to cook them in batches if your air fryer is small.
Air fry the fritters at 350°F (175°C) for approximately 6-8 minutes, or until they turn golden brown and are cooked through. Cooking times may vary depending on your air fryer model, so keep an eye on them.
Remove the pumpkin fritters from the air fryer and let them cool slightly before serving. Optionally, dust with powdered sugar or serve with a drizzle of maple syrup for added sweetness.
