Ingredients

Pie Crust

1 unbaked 9-inch pie crust

Butterscotch Filling

1 cup packed dark brown sugar
¼ cup cornstarch
¼ teaspoon salt
2 cups whole milk
½ cup heavy cream
4 large egg yolks
4 tablespoons unsalted butter
2 teaspoons vanilla extract

Whipped Cream Topping

1 cup cold heavy whipping cream
2 tablespoons powdered sugar
½ teaspoon vanilla extract

Optional garnish:

Butterscotch chips
Caramel drizzle
Chocolate curls
Toasted pecans

How to Make Butterscotch Pie

Step 1: Blind-Bake the Pie Crust

Preheat the oven to 375°F (190°C).

Fit the pie dough into a 9-inch pie plate and crimp the edges.

Line the crust with parchment paper and fill it with pie weights or dried beans.

Bake for approximately 15 minutes.

Carefully remove the parchment and weights and continue baking for another 8–12 minutes, or until the crust is golden and fully baked.

Allow it to cool completely.

Because the butterscotch filling is cooked separately, the crust needs to be fully baked before filling.

Step 2: Combine the Dry Ingredients

In a medium saucepan, whisk together:

Brown sugar
Cornstarch
Salt

Breaking up any brown sugar lumps now will help produce a smoother custard.

Step 3: Add the Milk and Cream

Gradually whisk in the whole milk and heavy cream.

Place the saucepan over medium heat.

Cook while whisking frequently until the mixture becomes hot and begins to thicken.

Don’t walk away from the saucepan—the bottom can scorch if it isn’t stirred.

Step 4: Temper the Egg Yolks

Whisk the egg yolks in a separate bowl.

Slowly pour approximately ½ cup of the hot milk mixture into the yolks while whisking constantly.

Add another small amount of the hot mixture and continue whisking.

This gradually warms the eggs so they don’t scramble.

Step 5: Finish the Custard

Slowly whisk the tempered egg mixture back into the saucepan.

Continue cooking over medium-low heat, whisking constantly, until the custard becomes thick and begins to bubble.

Once bubbling, cook for about 1 additional minute while stirring.

The filling should be thick enough to coat the back of a spoon.

Step 6: Add Butter and Vanilla

Remove the saucepan from the heat.

Immediately stir in:

Butter
Vanilla extract

Continue stirring until the butter melts completely.

The filling should now be smooth, glossy, and richly scented with brown sugar and vanilla.

Step 7: Fill the Pie

Pour the warm butterscotch custard into the cooled pie crust.

Smooth the top with a spatula.

Press plastic wrap directly against the surface of the filling if you don’t want a skin to form.

Step 8: Chill

Refrigerate for at least 4 hours, preferably longer.

The filling needs sufficient time to become completely cold and firm enough for clean slices.

Step 9: Make the Whipped Cream

Shortly before serving, beat the cold heavy cream until it begins to thicken.

Add powdered sugar and vanilla.

Continue beating until medium peaks form.

Don’t overbeat.

Step 10: Decorate and Serve

Spread or pipe the whipped cream over the chilled pie.

For an extra-special finish, add a light caramel drizzle or a few toasted pecans.

Slice and serve cold.

What Gives Butterscotch Its Flavor?

Butterscotch is traditionally associated with the combination of brown sugar and butter.

Brown sugar contains molasses, giving the filling a deeper caramel-like flavor than ordinary granulated sugar.

Butter adds richness and rounds out that molasses flavor.

Vanilla and a small amount of salt make the butterscotch flavor even more pronounced.

Light Brown Sugar vs. Dark Brown Sugar

Either works.

Dark brown sugar provides a stronger molasses flavor and creates a deeper-colored filling.

Light brown sugar produces a milder, sweeter butterscotch flavor.

For an old-fashioned pie with a pronounced butterscotch character, dark brown sugar is an excellent choice.

The Secret to Smooth Butterscotch Custard

Three things matter most: constant stirring, proper egg tempering, and enough cooking time.

Add the hot liquid gradually to the egg yolks instead of pouring everything together.

Once the eggs are incorporated, cook the custard until properly thickened.

If you remove it from the heat too early, the finished pie may not set firmly enough to slice.

How Thick Should the Filling Be?

Before pouring it into the crust, the filling should resemble a thick pudding.

When you run a spatula across the bottom of the saucepan, the mixture should briefly leave a visible trail.

Remember that it will become considerably firmer after several hours in the refrigerator.

Old-Fashioned Butterscotch Meringue Pie

For an even more traditional presentation, replace the whipped cream with meringue.

Use the egg whites left from making the custard.

You’ll need approximately:

4 egg whites
½ teaspoon cream of tartar
½ cup granulated sugar
½ teaspoon vanilla

Beat the egg whites and cream of tartar until foamy.

Gradually add the sugar while beating until glossy stiff peaks form.

Spread the meringue over the hot filling, making sure it touches the crust around the entire edge.

Bake at 350°F (175°C) until the meringue is attractively golden.

Cool and then refrigerate.

Butterscotch Cream Pie

For an especially creamy version, prepare the pie as written and top it generously with whipped cream.

Finish with:

Caramel drizzle + toasted pecans + a tiny pinch of flaky salt.

The slightly salty finish balances the sweet brown sugar filling beautifully.

Butterscotch Pie with Graham Cracker Crust

You don’t have to use pastry crust.

Combine:

1½ cups graham cracker crumbs
¼ cup granulated sugar
6 tablespoons melted butter

Press into a 9-inch pie plate.

Bake at 350°F (175°C) for approximately 8–10 minutes.

Cool completely before adding the butterscotch filling.

Butterscotch Pie with Vanilla Wafer Crust

Vanilla wafers also pair beautifully with butterscotch.

Combine crushed vanilla wafers with melted butter and a small amount of sugar.

Press into the pie plate, bake briefly, and cool before filling.

The vanilla-cookie flavor makes this variation especially nostalgic.

Salted Butterscotch Pie

Add a little flaky sea salt over the whipped cream immediately before serving.

Don’t overdo it.

A small amount of salt contrasts with the rich brown sugar custard and makes the butterscotch flavor taste more intense.

Butterscotch Pecan Pie

Toast approximately ½ cup chopped pecans.

Sprinkle some over the crust before adding the filling.

Use the remaining pecans to decorate the whipped cream.

This adds crunch to an otherwise very smooth dessert.

Chocolate Butterscotch Pie 🍫

Chocolate and butterscotch work surprisingly well together.

Add chocolate curls or mini chocolate chips over the whipped cream.

For a more dramatic dessert, spread a thin layer of melted chocolate over the cooled crust and allow it to set before adding the butterscotch filling.

Why Didn’t My Butterscotch Pie Set?

The most likely reason is that the custard wasn’t cooked long enough.

Cornstarch needs sufficient heat to properly thicken the filling.

Another possibility is cutting the pie before it has completely chilled.

Give it at least 4 hours in the refrigerator. Overnight chilling is even better when you want very neat slices.

Why Is My Filling Lumpy?

Lumps can result from:

Adding hot liquid to eggs too quickly
Not whisking continuously
Cooking over excessively high heat
Allowing custard to scorch on the bottom

If you notice small lumps, immediately pass the hot custard through a fine-mesh strainer before adding the butter and vanilla.

Why Is My Pie Crust Soggy?

The crust must be completely baked before the custard goes in.

For additional protection, brush the hot baked crust lightly with beaten egg white and return it to the oven briefly.

Once cooled, this creates a thin barrier between the crust and creamy filling.

Can I Make Butterscotch Pie Ahead?

Yes. In fact, it’s an excellent make-ahead dessert.

Prepare the crust and filling the day before serving.

Cover and refrigerate overnight.

Add whipped cream and decorative toppings shortly before serving.

This gives the filling plenty of time to set.

How to Get Clean Pie Slices

Make sure the pie is thoroughly chilled.

Use a sharp knife and wipe the blade clean between every slice.

For especially neat presentation, refrigerate overnight before cutting.

Storage

Keep Butterscotch Pie refrigerated.

Cover the pie carefully and enjoy it within approximately 3–4 days.

If you’re using whipped cream, keep the pie cold until shortly before serving.

Can You Freeze Butterscotch Pie?

Custard pies aren’t the best candidates for freezing because the filling can become watery or grainy after thawing.

For the smoothest texture, make this pie fresh and store it refrigerated.
