Gooey, chocolatey filling tucked into warm pumpkin donut holes makes Nutella Stuffed Pumpkin Donut Holes satisfying, especially when rolled in cinnamon sugar while still warm.
Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Spray a mini muffin pan with baking spray; set aside.
In a medium bowl, whisk together the melted butter, brown sugar, buttermilk, pumpkin puree, egg, and vanilla.
In a separate bowl, whisk together the flour, baking powder, pumpkin pie spice, cinnamon, nutmeg, and salt. Gradually add the dry ingredients to the wet ingredients, and fold until combined.
Spoon the batter into the mini muffin pan, filling each well about ¾ of the way full.
Place the pan in the oven and bake for 10–14 minutes, or until the tops spring back when touched. Remove from the oven and allow the doughnut holes to cool in the pan for 3–4 minutes before transferring them to a wire rack to cool completely.
Meanwhile, melt the butter in a small bowl. In a separate bowl, combine the cinnamon and sugar. Brush or dunk each doughnut hole in the melted butter, removing any excess (they should be covered in butter but not dripping). Then dip each doughnut hole in the cinnamon-sugar mixture, coating well.
Using a pastry bag fitted with a filling tip, insert the tip into the side or bottom of each doughnut hole and fill with Nutella. The doughnut will expand as it fills—take care not to let the doughnut crack. Enjoy immediately!
