Start by preheating your oven to 350 degrees Fahrenheit and spray your donut pan with a non-stick spray. I used avocado oil.
Whisk the flour, granulated sugar, baking powder, salt, and ground cinnamon in a large bowl.
Add the dairy-free milk, apple sauce and 1 tablespoon of melted butter to the large bowl and whisk until all smooth. The batter will be on the thicker side, not too runny.
Put the batter in a piping bag and fill the donut pan. Be careful not to overfill, each should contain about ¾ batter. If you fill to the top, you might lose your hole, as it rises in the oven.
Put the mold in the oven for about 20 minutes or until light golden brown. After they are cooked, take them out of the oven and let them cool off in the pan for about 10 minutes.
Grab two small bowls for your toppings, mix the sugar and cinnamon in one bowl, and melt the ¼ vegan butter in the other bowl. Then start to dip each donut in the butter and then the cinnamon sugar. You can dip both sides, or just one side, depending on your preference.
