In a large bowl, whisk the flour, baking powder, salt, sugar, and pumpkin spice.
In a small bowl, mix the melted coconut oil, non-dairy milk, pumpkin puree, and vanilla together.
Pour wet ingredients into dry ingredients and mix well to combine.
Divide batter evenly between the 24 muffins cups.
Bake for 8-10 minutes (until a tester comes out clean from the largest muffin).
While muffins are baking, put melted coconut oil in a small bowl and mix the sugar and cinnamon in another bowl.
Remove muffins from oven and cool for 10 minutes in tin.
Remove muffins from tin and place on a cooling rack.
While still warm, dip 1 muffin at a time into the oil first. Make sure the entire top is coated with the oil, shake off any excess. Then dip the same muffin into the sugar/cinnamon mixture, ensuring that the entire top is covered with the cinnamon sugar mix. Place muffin back on cooling rack.
Repeat with entire batch until done.
Notes
PLEASE read the "Before Making This Recipe" section above, before starting.
It's important to know that different gluten-free flour blends use different ingredients and ratios, so results will always vary if you substitute. I have never used any other flour to make this recipe (other than Bob's Red Mill Gluten-Free All-Purpose Baking Flour (the one in the red bag that you see in that link, NOT the flour in the blue bag!), so please know that your results may not be the same as mine if you substitute with a different blend.
This recipe will NOT work with coconut flour.
Have a look at the batter in this similar recipe to get an idea. If you use the flour recommended in this recipe and follow the recipe exactly as it is written, your recipe will work perfectly.
Store uneaten muffins in an airtight container in the fridge for up to 2-3 days. The longer they sit, the more the cinnamon sugar on top will melt, so it's best to eat them as quickly as possible.
