Spray your cake pops baking pan OR mini muffin pan with cooking oil spray; set aside.
In a large bowl, whisk together flour, sweetener (or sugar), baking powder, salt and cinnamon.
Make a well in the centre of the dry ingredients and in the oil, egg, sour cream, vanilla and cider (or juice).
Whisk the wet ingredients first, and then incorporate them into the dry ingredients, mixing slowly until just combined.
Slowly stir the apples through the batter.
Fill each hole with the batter to the top and bake for 20-25 minutes, or until golden and set (insert a toothpick into each donut hole and if it comes out clean, it's baked through).
In the meantime, pour icing sugar out into a bowl and slowly mix the maple syrup through.
Stir the milk through until smooth.
Add one extra tablespoon of milk only if needed (if the glaze is too thick).
Dip each donut hole into the glaze and flip with a spoon to evenly coat.
Allow excess glaze to drip off and place on a baking tray lined with baking/parchment paper until glaze has set.
