Preheat your oven to 180°C/350°F and grease your donut pan if it’s not non-stick.
Whisk together the flour, baking powder, cinnamon and salt.
In a separate bowl, whisk the molasses, yogurt, milk, oil, vanilla and black pepper.
Add in the flour mixture and whisk just until smooth.
Pipe (using a piping bag or ziploc bag with the corner cut off) or spoon the batter a bit more than halfway up the mold.
Bake for about 17-20 minutes or until a toothpick inserted comes out clean. Let them cool about 3-5 minutes in the pan before removing and tossing in the sugar of your choice.
