Preheat your oven to 350°F (175°C).
In a mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, salt, ground cinnamon, and ground nutmeg until well combined.
In another bowl, mix together canned pumpkin puree, egg, milk, melted butter, and vanilla extract until smooth and creamy.
Gradually fold the wet ingredients into the dry mixture until just combined; do not overmix.
Spoon small amounts of batter onto a lined baking sheet or mini muffin tin and bake for about 12-15 minutes or until golden brown on top.
Once cooled slightly, dust your baked pumpkin fritter bites with powdered sugar before serving.
