Butterscotch Pie

Butterscotch pie is one of those old-fashioned desserts that doesn’t need much fuss to feel special. It has a rich brown-sugar flavor, a smooth, creamy filling, and a buttery sweetness that’s especially good tucked into a crisp pie crust.

The filling is cooked gently on the stovetop until thick and silky, then poured into the baked crust to set. Once chilled, it slices beautifully while staying soft and creamy enough to melt in your mouth.

It’s a lovely dessert for Sunday dinner, holiday meals, or anytime you want something a little different from chocolate or fruit pie. A dollop of softly whipped cream on top is all it really needs.

Getting A Smooth Butterscotch Filling

The key to a creamy filling is patience. Cook the brown sugar, butter, and milk mixture over medium-low heat and keep stirring so nothing scorches on the bottom of the pan.

When the custard is thick enough to coat the back of a spoon, take it off the heat. Tempering the egg yolks with some of the hot mixture before adding them back to the saucepan helps prevent scrambling and gives the filling that smooth, custardy texture.

Ingredients You’ll Need

You only need a handful of simple ingredients to make this rich, creamy pie.

• 1 9-inch baked pie crust
• 1 cup packed light brown sugar
• 1/4 cup unsalted butter
• 1/4 cup all-purpose flour
• 2 cups whole milk
• 3 large egg yolks
• 1 teaspoon vanilla extract
• 1/4 teaspoon salt
• Whipped cream, for serving

How To Make Butterscotch Pie

Step 1: Prepare the filling. In a medium saucepan, melt the butter over medium heat. Add the brown sugar and cook for 2–3 minutes, stirring frequently, until the sugar is softened and the mixture looks glossy.

Step 2: Add the flour. Sprinkle the flour over the brown sugar mixture and whisk constantly for about 1 minute. This cooks out the raw flour taste and helps create a smooth base for the custard.

Step 3: Add the milk. Gradually whisk in the milk, adding it slowly at first to prevent lumps. Continue cooking over medium-low heat, stirring often, until the mixture is hot and begins to thicken.

Step 4: Temper the egg yolks. In a small bowl, whisk the egg yolks until smooth. Slowly pour about 1 cup of the hot milk mixture into the yolks while whisking constantly. Pour the warmed yolks back into the saucepan.

Step 5: Thicken the custard. Continue cooking over medium-low heat for 3–5 minutes, stirring constantly, until the filling is thick enough to coat the back of a spoon. Don’t let it boil vigorously, or the eggs may curdle.

Step 6: Finish the filling. Remove the saucepan from the heat and stir in the vanilla and salt. If the custard has any small lumps, pour it through a fine-mesh strainer before filling the crust.

Step 7: Fill and chill. Pour the warm butterscotch filling into the baked pie crust and smooth the surface. Let it cool at room temperature for about 30 minutes, then refrigerate for at least 4 hours, or until completely set.

Step 8: Serve. Slice the chilled pie with a sharp knife and add a spoonful of whipped cream just before serving.

Frequently Asked Questions

Can I Use A Store-Bought Pie Crust?

Absolutely. A refrigerated or frozen 9-inch pie crust is a convenient option. Just make sure it’s fully baked and cooled before adding the filling.

Why Is My Filling Too Thin?

The custard probably needs a little more cooking time. Return it to low heat and stir constantly until it noticeably thickens and coats the back of a spoon.

Can I Use Dark Brown Sugar?

Yes. Dark brown sugar gives the pie a deeper, more pronounced molasses flavor. Light brown sugar creates a slightly milder butterscotch taste.

Does The Pie Need To Be Refrigerated?

Yes. Because the filling contains milk and egg yolks, the finished pie should be refrigerated rather than left at room temperature for an extended period.

How Long Should The Pie Chill?

Give it at least 4 hours. Overnight is even better if you’re making it ahead, since the filling has plenty of time to firm up.

Can I Make It Ahead?

Definitely. Butterscotch pie is a great make-ahead dessert. Prepare it the day before serving and keep it covered in the refrigerator.

Recipe Variations

Dark Brown Sugar Butterscotch Pie

Swap the light brown sugar for dark brown sugar for a richer, more caramel-like flavor.

Bourbon Butterscotch Pie

Add 1–2 tablespoons of bourbon along with the vanilla for a warm, grown-up twist. Reduce the vanilla slightly if desired.

Chocolate Butterscotch Pie

Stir 2 ounces of finely chopped semisweet chocolate into the hot custard after removing it from the heat. Whisk until completely melted.

Salted Butterscotch Pie

Increase the salt slightly and sprinkle a small pinch of flaky sea salt over the whipped cream before serving.

Pecan Butterscotch Pie

Scatter toasted chopped pecans over the crust before pouring in the filling. The nuts add a lovely crunch against the creamy custard.

Storage

Keep leftover pie covered and refrigerated for up to 3–4 days. For clean slices, serve it cold or let it sit at room temperature for about 10 minutes before cutting. Freezing isn’t recommended because the custard can become watery or grainy after thawing.

What To Serve With Butterscotch Pie

Butterscotch pie is rich enough to stand on its own, but a little whipped cream makes each slice feel lighter and adds a nice contrast to the sweet filling. You could also serve it with a scoop of vanilla ice cream, a drizzle of warm caramel sauce, or a sprinkling of toasted pecans if you want a little extra texture.

For the cleanest slices, make sure the pie has chilled completely before cutting. A sharp knife wiped clean between slices will give you those neat layers of crust and creamy butterscotch filling.

If you’re serving it for a dinner or gathering, making it the day before is the easiest approach—the overnight chill gives the custard plenty of time to set.

This Butterscotch Pie is a rich, creamy dessert with a buttery homemade butterscotch filling and a perfectly flaky crust. It’s sweet, comforting, and easy to make, making it a delicious choice for holidays, family gatherings, or any time you’re craving an old-fashioned treat.

Ingredients

For the Pie:

• 1 9-inch baked pie crust, cooled
• 1 cup packed light brown sugar
• ¼ cup cornstarch
• ½ teaspoon salt
• 2 cups whole milk
• 3 large egg yolks
• 3 tablespoons unsalted butter
• 1 teaspoon vanilla extract

For the Whipped Cream:

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

Instructions

Prepare the filling: In a medium saucepan, whisk together the brown sugar, cornstarch, and salt until evenly combined.

Gradually whisk in the milk until smooth. Place the saucepan over medium heat and cook, whisking frequently, until the mixture becomes thick and begins to gently bubble.

Temper the egg yolks: In a separate bowl, whisk the egg yolks. Slowly drizzle about ½ cup of the hot milk mixture into the yolks while whisking constantly.

Pour the tempered egg mixture back into the saucepan. Continue cooking for about 2–3 minutes, whisking constantly, until the filling is thick and creamy.

Remove from the heat and immediately stir in the butter and vanilla until the butter has completely melted and the filling is smooth.

Fill the crust: Pour the warm butterscotch filling into the cooled baked pie crust. Smooth the top with a spatula.

Press a piece of plastic wrap directly against the surface of the filling to prevent a skin from forming. Refrigerate for at least 3 hours, or until completely chilled and set.

Make the whipped cream: Beat the heavy cream, powdered sugar, and vanilla until soft-to-medium peaks form.

Remove the chilled pie from the refrigerator and top with the whipped cream. Slice and serve cold.
