Ingredients
- 1 and 1/2 cups graham cracker crumbs
- 1/3 cup granulated sugar
- 6 tablespoons unsalted butter, melted
- 1 cup packed dark brown sugar
- 1/4 cup cornstarch
- 1/2 teaspoon salt
- 2 and 1/2 cups whole milk
- 1/2 cup heavy cream
- 4 large egg yolks
- 4 tablespoons unsalted butter, cut into pieces
- 2 teaspoons pure vanilla extract
- 1 cup chopped walnuts, lightly toasted
Method
- Preheat your oven to 350 degrees Fahrenheit. In a medium bowl, stir together the graham cracker crumbs, granulated sugar, and melted butter until the mixture resembles wet sand and holds together when pressed.
- Press the crumb mixture firmly and evenly into the bottom and up the sides of a 9-inch pie dish. Bake for 10 to 12 minutes until the crust is set and lightly golden. Remove from the oven and allow it to cool completely on a wire rack.
- In a medium heavy-bottomed saucepan, whisk together the brown sugar, cornstarch, and salt until well combined. Gradually pour in the milk and heavy cream, whisking continuously to prevent lumps.
- Place the saucepan over medium heat and cook, stirring constantly, until the mixture begins to thicken and just comes to a gentle boil, about 8 to 10 minutes. Let it bubble for one full minute while continuing to stir.
- In a small bowl, lightly beat the egg yolks. Slowly ladle about one cup of the hot butterscotch mixture into the yolks, whisking constantly to temper them. Pour the tempered yolk mixture back into the saucepan and return to medium heat.
- Cook for an additional 2 minutes, stirring constantly, until the filling is thick and glossy. Remove from heat and stir in the butter pieces and vanilla extract until the butter is fully melted and the filling is smooth and velvety.
- Fold in about three-quarters of the toasted walnuts, reserving the rest for the top. Pour the warm butterscotch filling into the cooled graham cracker crust and spread it evenly.
- Scatter the remaining walnuts over the top of the filling. Press a sheet of plastic wrap directly against the surface of the filling to prevent a skin from forming and refrigerate for at least 4 hours, or overnight, until fully set.
- Slice and serve chilled. Enjoy every nostalgic, heavenly bite.
Tips for the Best Results
Use dark brown sugar rather than light brown sugar for the deepest, most authentic butterscotch flavor. The extra molasses content makes all the difference in achieving that rich, caramel-like depth that makes this pie so memorable.
Toasting the walnuts before adding them to the filling is a small step that makes a big impact. Spread them in a single layer on a dry skillet over medium heat for about 3 to 4 minutes, stirring frequently, until fragrant. This brings out their natural nuttiness and adds a gentle crunch that perfectly complements the creamy filling.
Do not rush the chilling time. This pie truly needs several hours in the refrigerator to set up properly. An overnight chill produces the cleanest, most beautiful slices and allows all the flavors to fully meld together into something truly special.
Make It Your Own
If you want to dress this pie up a little for a holiday gathering, a generous dollop of freshly whipped cream on each slice is never a bad idea. A light dusting of flaky sea salt over the top just before serving can also beautifully balance the sweetness of the butterscotch and make the flavors pop in a surprisingly wonderful way. However you serve it, this pie is sure to become a beloved tradition in your kitchen for generations to come.
