Preheat the oven to 350ºF.
Spray a mini donut pan with non-stick cooking spray. Set aside.
In a medium size bowl whisk together the pumpkin, brown sugar, canola oil, and milk.
In a small bowl combine the flour, baking powder, pumpkin pie spice, cinnamon, nutmeg and salt.
Next, slowly add the dry ingredients to the wet ingredients. Mix well until combined.
Place the batter into ziplock bag, and cut off the corner (you can also use a piping bag). Add the batter evenly into each donut cavity.
Bake for 10-12 minutes or until cooked . Use a toothpick and place in the center of the donut. If the toothpick comes out clean it is done. Allow the donuts to cool in the pan for 10 minutes.
Turn the pan upside down to release the donuts carefully onto a cooling rack. Melt the orange candy melts according to the package. TIP: Add canola oil to thin out the candy melts, it makes it much easier to handle!
Dip the top of each donut into the melted orange candy melts. Let each donut dry for a minute before adding the sprinkles. Let the candy melts harden.
Add a small pumpkin stem using a broken pretzel to each donut.
Use the green decorator gel icing to add a small green leaf or vine.
