In a mixing bowl, whisk together the flour, sugar, baking powder, cinnamon, nutmeg, ginger, and salt.
In another bowl, combine the pumpkin puree, melted butter, egg, and vanilla extract until well blended.
Gradually add the pumpkin mixture to the dry ingredients, stirring until a smooth dough forms.
Heat vegetable oil in a frying pan or deep fryer to 350°F (175°C).
Fill a pastry bag or Ziplock bag with the pumpkin dough, cutting off a small tip at the end.
Squeeze out small bites of dough into the hot oil, cutting them with scissors for even sizes.
Fry the bites for about 2-3 minutes or until golden brown, flipping them halfway through for even cooking.
Remove the churro bites with a slotted spoon and drain on paper towels.
In a small bowl, mix ¼ cup granulated sugar with 1 tablespoon ground cinnamon.
While still warm, roll the churro bites in the cinnamon sugar mixture until evenly coated.
