Indiana sugar cream pie is a custardy, cinnamon-dusted Hoosier classic made without eggs or fruit. This simple, family-friendly dessert has been a beloved tradition in Indiana for generations.
Preheat your oven to 425°F. Place the unbaked pie crust into a 9-inch pie dish and flute the edges as desired.
In a saucepan over medium heat, whisk together the sugar, flour, and salt. Gradually whisk in the heavy cream and milk, ensuring no lumps remain.
Continue to cook the mixture, stirring constantly, until it thickens and just starts to bubble, about 7–10 minutes. Do not let it boil vigorously.
Remove from heat and stir in the unsalted butter and vanilla extract until butter is fully melted and homemade custard is smooth.
Pour the custard filling into the prepared pie crust. Sprinkle the surface evenly with ground cinnamon. Bake at 425°F for 10 minutes, then reduce the heat to 350°F and bake for another 20–25 minutes until the filling is set but the center still jiggles slightly.
Remove pie from oven and cool completely on a wire rack. Chill for at least 2 hours before slicing so the filling sets for clean slices.
