Preheat the oven to 325. Very lightly grease 2 nonstick mini donut pans.
In a medium skillet heat oil and saute scallions on medium heat until translucent.
While scallions are cooking combine milk, yogurt and goat cheese in a medium bowl. Whisk in eggs. Add sun dried tomatoes and scallions mixed with the cooking oil.
In a separate bowl, combine flour, baking powder and salt. Make a well in the center and pour in the liquids. Mix gently with a spatula until just combined.
Use a pastry bag or a small spoon to neatly fill each donut cup no more than 3/4 full. Bake uncovered for 15-20 minutes, until they begin to brown and feel firm to the touch. Remove pan from oven and allow to cool.
Warm the goat cheese in a glass bowl in the microwave for about 15 seconds to make it easy to stir. Stir and mix in milk as needed to get a frosting like consistency. Once donuts have cooled enough cover them with frosting and garnish with freshly ground black pepper or sun dried tomato pieces.
Makes 24 donuts.
