Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners.
In a mixing bowl, combine the pumpkin puree, sugar, melted coconut oil, and vanilla extract.
In another bowl, whisk together the gluten-free flour, baking powder, baking soda, pumpkin pie spice, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Divide the batter evenly among the muffin cups.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
