Step 1

Heat the milk and oil in a saucepan over medium heat for 2 minutes or until the milk comes to a simmer. Add the flour and stir to combine. Transfer mixture to the bowl of a stand mixer. Beat for 2 minutes or until smooth and cooled slightly.

Step 2

Add the eggs, one at a time, beating well after each addition. Beat in the cheese until just combined. Use damp hands to shape tablespoonsful of batter into balls.
