I whisked together the gluten-free flour, baking powder, baking soda, sea salt, and half of the pumpkin spice. This ensures the rising agents and spices are evenly distributed for uniform donuts.
In a separate bowl, I mixed melted butter, egg, maple syrup, apple cider, and applesauce. This wet mixture creates a flavorful, moist base for the donuts.
I slowly added the dry ingredients into the wet, stirring just until combined. Over-mixing can make the donuts dense, so I stopped when everything looked incorporated.
I poured the batter into a plastic bag, snipped a corner, and filled my egg bites pan about ¾ full. The air fryer cooked them at 375°F for 10-12 minutes. They were done when a toothpick came out clean.
I melted a bit of butter and mixed sugar with the remaining pumpkin spice in a shallow dish. After brushing the donuts with butter, I rolled them in the sugar mixture for that classic fall sweetness.
