Preparation

• Preheat your oven to 350°F (175°C).
• Place your pie crust in a pie dish and bake according to the package instructions until golden brown.
• In a saucepan, combine the milk, heavy cream, and sugar. Heat over medium heat until warm, but not boiling.
• In a separate bowl, whisk together the egg yolks, cornstarch, vanilla extract, ground cinnamon, and salt.
• Slowly pour the warm milk mixture into the egg mixture, whisking constantly.
• Return the mixture to the saucepan and cook over medium heat, stirring continuously, until the custard thickens.
• Remove from heat and stir in the butter until melted and well combined.
• Pour the custard into the baked pie crust.
• Allow the pie to cool completely at room temperature, then chill in the refrigerator for at least 2 hours before serving.
