Step 1

Fill a large bowl with hot water and set aside.

Step 2

Add 1/2 cup milk, 1 1/2 teaspoons light corn syrup, 1 teaspoon vanilla extract, and 1/8 teaspoon kosher salt to a medium saucepan and stir to combine. Heat over low heat until warm, about 4 minutes. Gradually whisk in 3 1/2 cups powdered sugar until well combined.

Step 3

Transfer the saucepan to the bowl of hot water—either letting it float in the water or sit on top—to keep the glaze warm and runny. Dip donuts, one at a time, into the glaze and let excess drip off. Place glazed donuts on a wire rack. Glaze will start to dry and set after about 5 minutes.
