Preheat your oven to 350°F.
In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
In another bowl, combine the applesauce, coconut sugar, almond milk, oil, and vanilla extract. Stir well to combine.
Add the wet ingredients to the dry ingredients and stir until just combined. Be careful not to overmix.
Spoon the batter into the silicone donut mold, filling each mold about ⅔ full.
Bake in the oven for 12-15 minutes, or until the donuts are golden brown and a toothpick inserted into the center comes out clean.
While the donuts are baking, prepare the cinnamon sugar coating. Mix the sugar and cinnamon in a small bowl. Melt the vegan butter in a separate small bowl. Whisk the butter into the cinnamon sugar.
After baking, allow them to cool for about 5 minutes in the trays. When cool enough to touch, carefully pop each one out of the mold. Dip each donut in the cinnamon sugar glaxe. Place on a cooling rack to cool completey. Enjoy!
