Preheat your oven to 350°F (175°C) and generously grease a donut pan.

In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, light brown sugar, salt, baking powder, and pumpkin spice.

In another bowl, mix the wet ingredients: pumpkin puree, melted butter, and milk until smooth and creamy.

Gently fold the wet mixture into the dry ingredients until just mixed.

Spoon the batter into the prepared donut pan, filling each cavity about two-thirds full.

Place the filled donut pan in the preheated oven and bake for 10-11 minutes until golden brown.

Remove the donut pan from the oven and let the donuts cool in the pan for about 5 minutes.

While the donuts cool, melt some butter for the coating and mix together granulated sugar and ground cinnamon.

Once cooled, dip each donut into the melted butter and roll in the cinnamon sugar mixture.
