Preheat your oven to 350°F (175°C). Line a standard muffin tin with 9 cupcake liners.
02 -
In a medium bowl, whisk together the sweet potato puree, water or milk, vanilla extract, vinegar, and oil (or additional sweet potato puree if making oil-free). Let this mixture sit for at least 10 minutes. This resting time allows the vinegar to react with the other ingredients, which helps create a light texture.

While the wet mixture is resting, you can sift together the flour, sugar, cinnamon, salt, baking soda, baking powder, and optional ground ginger in a separate bowl. After the wet ingredients have rested for 10 minutes, add the dry ingredients to the wet ingredients and stir just until combined to form a smooth batter.
04 -
Using a spoon or ice cream scoop, divide the batter evenly among the 9 prepared cupcake liners, filling each about 2/3 of the way full. Don't overfill as the cupcakes will rise during baking.
05 -
Place the muffin tin in the preheated oven and bake for 18 minutes, or until a toothpick inserted into the center of a cupcake comes out clean or with a few moist crumbs.

Remove the cupcakes from the oven and let them cool in the tin for 5-10 minutes. Then transfer them to a wire rack to cool completely. These cupcakes actually taste even better the next day, and the liners will peel off more easily after the cupcakes have been stored for a day.
