You must reduce the apple cider. The trick to the flavor explosion in these apple cider mochi donuts is the concentrated apple cider. The apple cider needs to be reduced down on the stove to add a big flavor without the excess liquid. Be patient! It will reduce.
Pipe the donuts into the pan. Piping the batter helps make the donuts more even and easier to transfer to the pan. The batter will be relatively sticky so using a spoon may be difficult. You can alternatively use a zip-lock bag and cut a hole in the corner if you do not have a piping bag.
You can alternatively use a muffin pan to make muffins instead. You can grease your standard 12-cup muffin pan or use cupcake liners and fill them about 3/4 way full and bake for about 15-18 minutes or until a toothpick inserted comes out clean.
Storage Instructions: These donuts are best eaten immediately. You can store them in an airtight container at room temperature for 1-2 days. You can freeze the donuts, coated or not coated in the toppings, for up to 2 months.
