Banana cream pie is a stovetop custard layered with fresh banana slices inside a graham cracker crust, finished with whipped cream. The custard is cooked from scratch using egg yolks, cornstarch, and whole milk, so the texture is firmer and richer than anything from a box. Plan on about an hour of active work plus at least three hours of refrigerator time before you can slice it.
Why this recipe works
Two things make this pie reliable. First, tempering — adding the hot milk to the beaten yolks gradually before returning everything to the pan — keeps the eggs from scrambling and gives the custard a smooth, cohesive texture that slices cleanly. Second, the double banana layer matters: splitting the slices between two layers of custard rather than piling them all on the bottom means every slice gets fruit throughout, not just at the base. Both techniques are especially important when you’re making more than one pie at once, because a broken custard or uneven filling is much harder to fix at scale.
Common problems and fixes
- Custard stays thin and won’t thicken: The heat is probably too low. Once the tempered mixture goes back into the pan, keep it at a steady medium heat and whisk constantly. It needs to reach a full, bubbling simmer — not just steam — to activate the cornstarch fully. Give it the full 5–7 minutes before deciding it has failed.
- Skin forms on the custard while it cools: Press a sheet of plastic wrap directly onto the surface of the custard before you set it aside. Even a few minutes of air contact is enough to form a rubbery skin that won’t whisk back in smoothly.
- Bananas turn brown before serving: Slice the bananas as close to assembly time as possible. If you’re assembling several pies ahead of a party, a quick toss in lemon juice (about half a teaspoon per banana) slows browning without noticeably affecting flavor.
- Crust crumbles when sliced: The butter-to-crumb ratio needs to be right — the mixture should clump when you squeeze a handful. If it’s too dry, add melted butter a teaspoon at a time. Also make sure the crust is pressed firmly and evenly up the sides, not just patted loosely.
- Whipped cream weeps or deflates after a few hours: Skip the garnish — not worth the extra dish. If you need the pie to hold for more than two hours after topping, whip the cream to firm peaks rather than soft, or add a tablespoon of instant vanilla pudding powder to the cream before whipping to stabilize it without gelatin.
Banana Cream Pie
Equipment
- 9-inch pie dish
- Mixing Bowls
- Saucepan
- Whisk
- Rolling pin
Ingredients
For the Crust:
- 1 package graham crackers about 10 sheets
- ¼ cup granulated sugar
- ½ cup unsalted butter melted
For the Filling:
- 3 large egg yolks beaten
- 3 cups whole milk
- ¾ cup granulated sugar
- ¼ cup cornstarch
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter
- 3 medium ripe bananas sliced
For the Topping:
- 1 cup heavy whipping cream chilled
- 2 tablespoons powdered sugar
- ½ teaspoon vanilla extract
Instructions
Prepare the Crust:
- In a food processor, pulse the graham crackers until finely ground. Add the granulated sugar and melted butter, pulsing until combined. Press the mixture into a 9-inch pie dish, ensuring an even layer on the bottom and up the sides. Chill in the refrigerator while preparing the filling.
Make the Filling:
- In a saucepan, combine the milk and granulated sugar and heat until steam rises. In a bowl, whisk together the cornstarch and egg yolks, then gradually add the hot milk mixture, whisking constantly.
- Return the mixture to the saucepan over medium heat, whisking until thickened, about 5-7 minutes. Remove from heat, stir in vanilla extract and butter until smooth. Cool slightly.
Assemble the Pie:
- Arrange a layer of banana slices over the crust. Pour half of the custard over the bananas, spreading evenly, then add another layer of bananas and top with the remaining custard. Chill for at least 3 hours to set.
Prepare the Whipped Cream:
- In a chilled bowl, whip the heavy cream, powdered sugar, and vanilla extract until soft peaks form. Spread over the pie.
Notes
- For an extra touch of luxury, consider caramelizing the top with a blowtorch for an indulgent brûlée finish.

Your questions, answered
Can I make this pie the night before?
Yes — the assembled pie (without the whipped cream) keeps well covered in the refrigerator for up to 24 hours. Add the whipped cream topping within two hours of serving so it stays fresh and doesn’t weep into the custard.
Can I use a store-bought pie crust instead of making the graham cracker crust?
A pre-made graham cracker crust works fine and saves about 15 minutes. A standard pastry shell also works, but it needs to be fully blind-baked and cooled before you add the custard, or the bottom will be soggy.
How ripe should the bananas be?
Use bananas that are yellow with just a few small brown spots — ripe enough to be sweet, but still firm enough to hold their shape under the custard. Fully soft or heavily spotted bananas will turn mushy during the chill time and make the layers hard to distinguish when sliced.
