Instructions: In a saucepan, combine heavy cream, whole milk, and granulated sugar. Heat over medium heat, stirring occasionally until the mixture just starts to simmer. In a separate bowl, whisk the egg yolks until smooth. Gradually pour the hot cream mixture into the egg yolks, whisking constantly to prevent curdling. Return the mixture to the saucepan and cook over low heat, stirring constantly, until it thickens enough to coat the back of a spoon. Do not boil. Remove from heat and stir in malted milk powder and vanilla extract until well combined. Transfer the mixture to a bowl and cover with plastic wrap, ensuring the wrap touches the surface of the custard to prevent a skin from forming. Chill the custard in the refrigerator for at least 4 hours or overnight until completely cold. Once chilled, churn the custard in an ice cream maker according to the manufacturer's instructions. During the last few minutes of churning, add crushed peanut brittle and chopped milk chocolate chunks. Transfer the churned ice cream to a freezer-safe container, cover, and freeze until firm, preferably overnight.
