Preheat oven to 375. Spray a 6-donut donut pan and set aside. If you have two donut pans, prepare a second one with cooking spray.
Whisk together gluten free flour, baking powder, baking soda, sea salt and pumpkin spice.
In another bowl combine melted butter, egg, coconut sugar, apple cider and applesauce.
Slowly fold dry ingredients into wet. Stir until just combined, do not over mix.
Using a plastic bag, place donut mixture into bag and snip one bottom corner. Fill donut pan with three circles of donut batter. Gently tap donut pan to even them out.
Bake for 10 minutes. Donuts will be done when a toothpick comes out clean.
