Banana Cream Pie Recipe

Overview

This banana cream pie has three distinct layers: a crisp, fully baked pie crust, fresh banana slices, and a smooth stovetop vanilla custard. A little lemon juice helps slow browning on the bananas without making them taste lemony.

The pie needs at least 4 hours to chill, so the custard has time to set and the slices hold together. For the neatest texture, add the whipped cream shortly before serving or up to a few hours ahead.

Ingredients

• 1 fully baked and cooled 9-inch pie crust, homemade or store-bought
• 3 medium ripe but firm bananas, about 1 1/4 pounds total
• 1 teaspoon fresh lemon juice
• 2/3 cup granulated sugar
• 1/4 cup cornstarch
• 1/4 teaspoon fine salt
• 3 large egg yolks
• 2 cups whole milk
• 2 tablespoons unsalted butter
• 2 teaspoons vanilla extract
• 1 cup cold heavy cream
• 2 tablespoons powdered sugar
• 1/2 teaspoon vanilla extract
• Optional: 2 tablespoons finely grated semisweet chocolate or extra banana slices for decorating

How to make it

1. Prepare the crust. If using a homemade crust, bake it according to its recipe until the bottom and edges are fully golden, then cool it completely. If using a refrigerated or frozen crust, bake it according to the package directions for a 9-inch single-crust pie. Do not fill a warm crust; residual heat can soften the pastry.

2. Slice the bananas. Peel 2 1/2 bananas and cut them into rounds about 1/4 inch thick. Toss them gently with the lemon juice in a bowl. Slice the remaining half banana just before decorating the finished pie so those slices look freshest.

3. Make the custard base. In a medium saucepan, whisk the sugar, cornstarch, and salt until evenly combined. Whisk in the egg yolks until the mixture is thick and smooth, then gradually whisk in the milk. Adding the milk slowly helps prevent lumps.

4. Cook the custard. Set the saucepan over medium heat and whisk constantly, especially around the corners and across the bottom. After about 6 to 9 minutes, the mixture will thicken. Once it reaches a full bubble, continue whisking and cook for 1 minute. The custard should coat the whisk and fall back in thick ribbons; when you lift the whisk, the trail should remain visible for a moment.

5. Finish the filling. Remove the pan from the heat. Whisk in the butter and 2 teaspoons vanilla until the butter melts and the custard is glossy. If the custard has small lumps, pour it through a fine-mesh strainer into a bowl.

6. Layer the pie. Arrange half of the banana slices over the cooled crust, overlapping them slightly. Spread half of the warm custard over the bananas, working it into the gaps. Add the remaining banana slices, then spread the remaining custard on top. Press plastic wrap directly against the custard’s surface to prevent a skin from forming.

7. Chill until set. Refrigerate the pie for at least 4 hours, or until the center feels firmly set when the pan is gently nudged. For the cleanest slices, chill it overnight. Do not try to slice it while the filling is still loose or warm.

8. Whip the cream. Just before serving, beat the cold heavy cream, powdered sugar, and 1/2 teaspoon vanilla in a chilled bowl on medium-high speed until it forms medium-stiff peaks. The cream should hold its shape when the beaters are lifted but still look smooth, not grainy.

9. Finish and serve. Spread or pipe the whipped cream over the chilled pie. Decorate with the reserved banana slices and, if desired, grated chocolate. Cut with a sharp knife, wiping the blade between slices for cleaner edges.

Expert tips

• Use bananas that are yellow with a few small spots but still firm. Very soft bananas release more moisture and can make the layers slippery.
• Whisk the custard continuously while it cooks. If it sits on the heat without stirring, the cornstarch can settle and the egg yolks may scramble.
• The custard must reach a full boil for 1 minute to activate the cornstarch. Removing it as soon as it merely thickens can leave a filling that loosens in the refrigerator.
• If the custard looks lumpy, strain it while warm. If it smells strongly eggy or contains firm scrambled bits, it was overheated and is better replaced.
• For a shortcut, use 3 cups prepared vanilla pudding, but choose a thick pudding rather than a pourable sauce. The from-scratch custard gives the pie a richer, more delicate texture.
• If the crust softens quickly, brush the cooled crust with 2 ounces melted and cooled semisweet chocolate before adding the bananas. Let the chocolate set first; it creates a thin moisture barrier.

Serving and storage

Serve the pie cold, ideally within a few hours of adding the whipped cream. Keep it refrigerated whenever it is not being served. Cover it loosely so the topping is not crushed, and store leftovers in the refrigerator for up to 3 days. The bananas will darken gradually and the crust will soften over time, so the pie is at its best on the day it is assembled.

Do not leave the pie at room temperature for more than 2 hours, or more than 1 hour if the room is above 90°F (32°C). Freezing is not recommended: the custard can become watery and the bananas can turn soft when thawed.

Frequently asked questions

Can I make banana cream pie the day before?

Yes. Assemble the crust, bananas, and custard up to 1 day ahead, cover the surface, and refrigerate. Add the whipped cream shortly before serving for the freshest texture.

Why is my banana cream pie runny?

The custard may not have reached a full boil, or it may not have cooked for the full 1 minute after boiling. It also needs at least 4 hours of chilling. Make sure the cornstarch is measured accurately and the custard is visibly thick enough to leave a brief trail when whisked.

How do I keep bananas from turning brown in banana cream pie?

Toss the slices gently with a small amount of fresh lemon juice before layering. Use firm, ripe bananas and assemble the pie soon after slicing. Some slight darkening is normal during storage.

Can I use a graham cracker crust?

Yes. Use one 9-inch prepared graham cracker crust and chill it fully before filling. It will have a sweeter, more crumbly texture than a pastry crust.
