This brown sugar butterscotch pie is a silky, caramel flavored custard in a prebaked crust, finished with whipped cream and crunchy pecans. The filling cooks on the stovetop in about ten minutes, then the pie chills for three hours, so plan on just under four hours from start to slice.
Butter and brown sugar melt together into a rich butterscotch base, and egg yolks and cornstarch turn it into a creamy filling that slices cleanly.

Why This Brown Sugar Butterscotch Pie Recipe Works
Cooking brown sugar in butter gives true butterscotch flavor, with a deep caramel note and a slight savory edge from the salt.
Egg yolks and cornstarch work together as thickeners. The cornstarch sets the filling firmly, while the yolks add richness and a silky texture.
The pie needs time to chill, which lets the filling set so each slice holds a neat shape. Whipped cream and pecans add contrast in texture on top.
Ingredients for Brown Sugar Butterscotch Pie
- 1/2 cup unsalted butter
- 1 cup packed brown sugar
- 3 large egg yolks
- 1/4 cup cornstarch
- 2 cups whole milk
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
- 1 prebaked 9 inch pie crust
- 1 cup whipped cream for topping
- 1/2 cup chopped pecans for garnish
Brown sugar. Packed dark or light brown sugar both work, and dark gives a stronger caramel flavor.
Cornstarch. It sets the filling, so whisk it into the yolks before adding the milk to prevent lumps.
Egg yolks. Yolks add richness and color. Cook the finished filling to 160 degrees F so they are safe to eat.
Whole milk. Whole milk keeps the custard creamy and gives it enough body to set.
Pecans. Chopped pecans add crunch on top. Toast them lightly if you like a deeper nutty taste.
How to Make Brown Sugar Butterscotch Pie
1. Melt the butter and sugar In a saucepan over medium heat, melt the butter, then stir in the brown sugar until it dissolves and looks smooth.
2. Mix the yolks In a bowl, whisk the egg yolks, cornstarch, and salt, then whisk in the milk gradually so no lumps form.
3. Temper the mixture Slowly pour the warm butter and sugar mixture into the egg mixture, whisking constantly so the yolks do not scramble.
4. Cook the filling Pour everything back into the saucepan and cook over medium low heat, stirring constantly, for about 5 minutes until thick and bubbling gently. It should reach 160 degrees F.
5. Add the vanilla Remove the pan from the heat and stir in the vanilla extract.
6. Fill the crust Pour the warm filling into the prebaked crust, smooth the top, and let it cool at room temperature for 20 minutes.
7. Chill Refrigerate for at least 3 hours, until the filling is completely set.
8. Top and serve Add whipped cream and chopped pecans just before slicing.
How to Serve Brown Sugar Butterscotch Pie
Cut the pie with a sharp knife wiped clean between slices, and top each wedge with a spoonful of whipped cream and a few pecans. A small slice goes well with coffee. For a dessert table, add New York cheesecake, dark chocolate mousse, caramel banana bread pudding, and moist vanilla cake for a range of textures.
How to Store and Reheat Brown Sugar Butterscotch Pie
Cover the pie and refrigerate it for up to 3 days. Add the whipped cream and pecans just before serving so they stay fresh and crisp. Do not freeze it, because the custard filling can turn watery after thawing. Serve slices cold, straight from the refrigerator.
Tips and Variations for Brown Sugar Butterscotch Pie
Whisk constantly. Brown sugar and milk scorch easily, so keep the whisk moving across the bottom of the pan.
Strain the filling. Pour it through a fine mesh sieve into the crust for the smoothest texture.
Use a thermometer. A quick check for 160 degrees F confirms the egg yolks are fully cooked.
Chill fully. Resist slicing early, because a partly chilled filling will slump.
Add a brulee top. Sprinkle a thin layer of sugar on the cooled filling and use a kitchen torch for a crisp caramel crust before adding toppings.
Choose your crust. A homemade crust adds buttery flavor, but a store bought one saves time.
Stabilize the cream. Whip the cream with a spoonful of powdered sugar so it holds its shape longer on the pie.
Follow egg safety basics. Keep the pie chilled and read Montana State University Extension egg fact sheet for general guidance on handling eggs.
