• 3/4 cup sugar
• 3 tbsp. cornstarch
• 3 cups milk
• 4 beaten egg yolks
• 1 tbsp. unsalted butter
• 1 tbsp. vanilla extract

Whisk together the sugar and cornstarch in a saucepan. Stir over medium heat until it becomes thickened and bubbly. Cook 2 minutes more. Pour 1/2 cup of the milk mixture into the beaten egg yolks and whisk. Repeat this 2-3 more times. Pour the egg mixture back into the saucepan with the remaining milk. Bring to a gentle boil and stir constantly for 2 minutes. Remove the pan from the heat; stir in the butter and vanilla. Pour into small bowls. Chill for 3-4 hours.
