Mix the flour, starch, salt, sugar and xanthan gum in a bowl

Add the applesauce and coconut oil, warmed milk and yeast. Mix together to form a soft dough

It should be more batter-like, a very soft dough, not sticky but not dense at all. If you made a ball of it and dropped it on counter top it would flatten a little. Don't be tempted to add more flour thinking that the dough is too soft

Mix the sugar and cinnamon from the topping ingredients together and sprinkle 2 tablespoons of it into the greased tin

Make balls out of the dough about 2 inches in diameter or enough dough to fit in the palm of your hand

Spray the donuts with the oil and sprinkle liberally with the cinnamon sugar

Place them in a single layer in the tin

If you want the caramel sauce topping to make the doughnuts into monkey bread, melt the leftover cinnamon sugar with just over 3/4 it's weight of butter in a pan until the sugar has dissolved

Pour over the coated donuts and bake for 25 - 30 minutes

Let cool in the tin for 10 minutes to let the caramel sauce thicken then invert onto a serving plate

It's probably better to make the balls half the size if doing this, around an inch wide, just because of the sweetness
