To prepare the dough, mix the pumpkin purée, glutinous rice flour, and sugar in a large bowl until the mixture is smooth.
Divide the dough into approximately 12 equal portions and roll each portion into a smooth ball.
Coat each ball with sesame seeds by rolling them in the seeds and gently pressing to ensure they stick. If the seeds don't adhere well, you can lightly spray the balls with water.
Place the sesame balls in a single layer in your air fryer and spray them with cooking oil.
Cook the balls at 400°F (200°C) for about 12 minutes, or until they are crispy and golden brown on the outside.
Serve immediately and enjoy!
