Butterscotch Cream Pie Bars: The Best Must-Have Make-Ahead Dessert

Butterscotch Cream Pie Bars With a Graham Cracker Crust

Butterscotch cream pie bars combine a crisp graham cracker crust, brown sugar custard, and a soft whipped cream topping in a square-pan dessert that is easier to portion than a traditional cream pie. The filling is cooked on the stove, poured over the baked crust, and chilled until firm enough to cut.

Dark brown sugar gives the homemade butterscotch pudding a deeper molasses flavor, while butter and vanilla round out the custard. These chilled dessert bars need at least four hours in the refrigerator, which makes them especially practical for preparing a day before serving.

Essential Concepts

• Use a 9-inch (23 cm) square pan lined with parchment.
• Cook the custard until it boils, then continue whisking for one minute.
• Chill the assembled bars for at least four hours.
• Add whipped cream after the custard has set.
• Store covered in the refrigerator for up to three days.

Total time: About 4 hours 50 minutes

Equipment

• 9-inch (23 cm) square baking pan
• Parchment paper
• Medium saucepan
• Mixing bowls
• Whisk
• Silicone spatula
• Electric hand mixer or stand mixer
• Offset spatula or spoon
• Sharp knife

Ingredients for the Graham Cracker Crust

• 2 cups graham cracker crumbs (200 g)
• 2 tablespoons packed light brown sugar (25 g)
• 1/4 teaspoon fine salt
• 1/2 cup unsalted butter, melted (113 g)

Ingredients for the Brown Sugar Custard

• 1 cup packed dark brown sugar (200 g)
• 1/3 cup cornstarch (40 g)
• 1/2 teaspoon fine salt
• 4 large egg yolks
• 3 cups whole milk (720 ml)
• 4 tablespoons unsalted butter, cut into pieces (57 g)
• 2 teaspoons pure vanilla extract (10 ml)

Ingredients for the Whipped Cream Topping

• 1 1/2 cups cold heavy cream (360 ml)
• 3 tablespoons confectioners’ sugar (24 g)
• 1 teaspoon pure vanilla extract (5 ml)
• Crushed graham crackers or shaved chocolate, optional

Prepare and Bake the Graham Cracker Crust

Heat the oven to 350°F (175°C). Line the pan with parchment paper, leaving enough overhang on two opposite sides to lift out the chilled dessert.

Combine the graham cracker crumbs, brown sugar, and salt in a bowl. Add the melted butter and stir until all the crumbs are evenly moistened. The mixture should resemble damp sand and hold together when pressed between two fingers.

Transfer the crumbs to the prepared pan. Press them into a compact, level layer using the flat bottom of a measuring cup or drinking glass. Pay particular attention to the corners, where loose crumbs can cause the bars to break during slicing.

Bake the graham cracker crust for 9 to 11 minutes. It should smell toasted and look slightly darker around the edges. Set the pan on a wire rack while preparing the filling. The crust does not need to become completely cold, but it should cool for at least 15 minutes.

Cook the Homemade Butterscotch Pudding

Place the brown sugar, cornstarch, and salt in a medium saucepan. Whisk until the cornstarch is distributed and no large sugar clumps remain.

Add the egg yolks and about 1/2 cup (120 ml) of the milk. Whisk the mixture into a smooth paste. Slowly pour in the remaining milk while whisking.

Set the saucepan over medium heat. Cook while whisking steadily, reaching into the corners of the pan where starch and egg can collect. The mixture will remain thin for several minutes, then begin to thicken as it approaches a simmer.

Once large bubbles break through the surface, reduce the heat slightly and continue cooking for one minute. Keep whisking during that minute. Cornstarch must reach a boil to develop its full thickening capacity, and the additional cooking time removes its raw, chalky flavor.

Remove the pan from the heat. Add the butter and vanilla, then whisk until the butter has melted and the brown sugar custard looks smooth and glossy.

If small cooked egg particles are visible, press the pudding through a fine-mesh strainer before assembling the bars. Straining is optional when the custard is already smooth.

Assemble and Chill the Dessert Bars

Pour the warm pudding over the graham cracker crust. Spread it into an even layer without scraping or disturbing the crust.

Place a sheet of plastic wrap directly against the pudding’s surface. Direct contact prevents a rubbery skin from forming. Allow the pan to stand at room temperature for about 20 minutes, then refrigerate it for at least four hours.

For the firmest slices, leave the bars in the refrigerator overnight. Do not freeze the pan to shorten the setting time. Partial freezing can leave the custard unevenly firm, and thawed pudding may release moisture.

Add the Whipped Cream Topping

Remove the plastic wrap after the custard has set.

Pour the cold heavy cream into a chilled mixing bowl. Add the confectioners’ sugar and vanilla. Beat at medium speed until the cream forms medium peaks. The cream should hold its shape while remaining smooth enough to spread.

Spoon the whipped cream over the chilled custard. Spread it to the edges in an even layer. Add crushed graham crackers or shaved chocolate just before serving, if desired.

Refrigerate the finished bars for 20 to 30 minutes before cutting. The brief final chill firms the whipped cream and makes slicing less messy.

How to Cut Clean, Even Bars

Use the parchment overhang to lift the dessert from the pan. Place it on a cutting board and peel the parchment away from the sides.

Run a sharp knife under hot water, then wipe it dry. Make one straight cut through the whipped cream, custard, and crust. Clean and warm the blade again before each subsequent cut.

For 16 servings, cut the square into four rows in each direction. These portions are rich enough for most dessert plates. Nine
