Instructions
Preheat oven to 325 degrees F. Prepare a 9-inch square metal baking pan by spraying it with nonstick spray. Place parchment paper in the bottom of the pan to create a sling.
Add milk and butter to a small saucepan. Set over low heat, just until the butter melts. Remove from heat. The mixture should not boil or simmer.
2 cups whole milk, ½ cup unsalted butter
In the bowl of your stand mixer fitted with the whisk attachment, add egg whites. Beat on medium-high speed for about 4-5 minutes, or until stiff peaks form. Set aside.
In a separate large bowl, add egg yolks, sugar, vanilla, salt, and cinnamon. Whisk for about 2 minutes, until pale and creamy.
