Using Piano Wire Whisk, whisk all ingredients until smooth. Set aside.
Preheat oven to 400° F (205°C).
In a bowl, using Piano Wire Whisk, whisk first 4 ingredients.
In a second bowl, using an electric mixer, beat butter and sugar until creamy. Add eggs one at a time, beating well after each addition.
Slowly mix in dry mixture and milk in batches: 3 batches dry; 2 batches milk mixed with vanilla extract. Be careful not to over mix.
Using a basting brush, lightly brush Mini Donut Mold with vegetable oil. Pipe or spoon dough into Mold, filling wells 2⁄3 full.
Bake until a toothpick comes out clean, approximately 12–15 minutes. Repeat with remaining batter.
To glaze, dip one side of each donut in glaze, and twist clockwise to coat. Place plain side down on a serving platter, and finish with Maple Bacon Sea Salt. Let glaze set before serving, approximately 5 minutes.
