1/2 cup (113 g) unsalted butter (melted and slightly cooled)
2 large eggs (room temperature)
2 cups (One 15 oz can or 425 g) pumpkin puree
2/3 cup (133 g) granulated sugar
2 teaspoons ground cinnamon
6 tablespoons (85 g) melted unsalted butter
Instructions:
Preheat oven to 350° F. Grease a donut tin (cavities with 3 ¾-inch diameter) with nonstick spray and set aside.
In a large bowl, whisk together the flour, baking soda, baking powder, salt and spices. Set aside.
In a medium bowl, whisk brown sugar, granulated sugar and melted butter together until butter is absorbed. Add eggs and vigorously whisk until combined. Stir in pumpkin puree.
Pour wet ingredients into the large bowl of dry ingredients and mix until no flour pockets remain (avoid over-mixing). Spoon or pipe batter into prepared donut tin.
Bake at 350° F for 12 to 14 minutes or until a toothpick inserted in the center comes out with little to no crumbs. Let the donuts cool in the pan for a couple minutes before transferring to a wire rack.
For the topping, whisk together the sugar and cinnamon. While the donuts are still a little warm, lightly brush them with melted butter, then generously coat the donuts in cinnamon sugar.
