Ingredients for old fashioned banana cream pie
Simple ingredients, nostalgic flavors—this pie tastes like grandma’s kitchen all over again.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 6 medium | Peeled and sliced lengthwise |
| All-Purpose Flour 🌾 | ½ cup | For banana filling thickener |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar preferred |
| Brown Sugar 🍚 | ¼ cup | Packed, for caramelization |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for custard |
| Vanilla Bean 🌸 | 1 whole | Split lengthwise for seeds |
| Large Egg Yolks 🥚 | 4 whole | Freshly separated |
| Heavy Cream 🥛 | 2 cups | Cold for custard |
| Old-Fashioned Oats 🌾 | 1 ½ cups | Quick or rolled oats |
| Light Brown Sugar 🍚 | ½ cup | Packed, for oat topping |
| Chopped Walnuts 🥜 | ½ cup | Toasted for crunch |
| Pie Crust 🥧 | 1 pre-made | Store-bought or homemade |
The bananas are the star, so pick ones that are just ripe enough—they should yield slightly to gentle pressure but not be mushy. Trader Joe’s and Whole Foods usually have perfect ones, but your local grocery store’s produce section works too. For the vanilla bean, Madagascar Bourbon is my go-to—it’s worth the splurge for that deep, rich flavor. The pie crust? Pillsbury’s refrigerated crust is my lazy-day secret, but homemade is better if you’ve got the time. Toast those walnuts in a dry pan for 5 minutes—they’ll smell amazing and add serious crunch to that oat topping.
No vanilla bean? Pure vanilla extract at double the amount works in a pinch. The oats can be quick or rolled—Bob’s Red Mill is my brand of choice. Short on walnuts? Pecans or almonds work great, but toast them first. The custard is forgiving, but don’t boil it—just heat until it thickens. For the banana filling, if you’re worried about the bananas getting too soft, underbake them slightly—they’ll firm up as they cool. And if you’re making this ahead, bake the filling first—it actually tastes better the next day.
This pie keeps beautifully—3-4 days in the fridge, covered tightly. The custard layer will firm up a bit, but it’s still creamy when sliced. For serving, I like to let it sit at room temperature for 20 minutes—the contrast between the warm crust and cool filling is perfect. Leftovers? Freeze individual slices for up to 3 months. Just thaw them overnight in the fridge before serving. The oat topping stays crunchy even after baking—trust me, it’s worth the extra minute of mixing.
Why You'll Love This Recipe
- No Overmixed Batter: I swear by this recipe because the crust comes together with just cold butter and flour—no chilling, no fuss. The bananas caramelize in the oven while the filling thickens, and honestly? That first bite of warm, spiced banana with the buttery crust underneath is the kind of simple magic I didn’t know I needed.
- Spiced Banana Bliss: Between us, the cinnamon and brown sugar in this filling turn ordinary bananas into something ridiculously good. The caramelized edges on the fruit? That’s the secret—it’s not just sweet, it’s got depth, like a hug from dessert.

Step-by-step instructions for old fashioned banana cream pie
Here's how to assemble this classic dessert with rich custard, banana swirls, and a crunchy oat topping.
Prepare the Banana Filling
In a medium saucepan, combine the 6 medium ripe bananas, 1.5 cups granulated sugar, 2 teaspoons ground cinnamon, and 0.5 teaspoon salt. Cook over medium heat, stirring frequently, until the bananas soften and the mixture reaches a thick, syrupy consistency—about 8-10 minutes. You'll know it's ready when the sauce coats the back of a spoon and the bananas are completely broken down.
Remove the pan from heat and let the banana mixture cool for 10 minutes. This cooling step is crucial—it prevents the custard from curdling when we mix it in later. While it cools, split the vanilla bean lengthwise and scrape out the seeds, adding both the seeds and the empty pod to the banana mixture. Stir well to infuse maximum vanilla flavor.
Make the Vanilla Bean Custard
In a separate bowl, whisk together the 4 whole large egg yolks and 0.5 cup unsalted butter until smooth. Gradually whisk in the 2 cups cold heavy cream. Slowly pour in the cooled banana mixture while whisking constantly to maintain a smooth texture.
Return the mixture to the saucepan and cook over medium-low heat, stirring constantly with a wooden spoon, until the custard thickens enough to coat the back of the spoon—about 5-7 minutes. The custard should be thick but still pourable, not scrambled. Remove from heat immediately once it reaches this consistency, as it will continue thickening as it cools.
Assemble the Pie
Preheat your oven to 375°F. Roll out the pre-made pie crust and fit it into a 9-inch pie dish, pressing gently to remove any air bubbles. Trim and crimp the edges as desired. Spread half of the banana custard mixture evenly into the crust, then arrange the sliced bananas in a circular pattern on top. Pour the remaining custard over the bananas, gently swirling with a knife to create marbled patterns.
Bake for 25-30 minutes, until the filling is set but still slightly jiggly in the center. The edges should be golden brown, and the filling should pull away slightly from the crust when gently shaken. Let the pie cool completely on a wire rack before adding the topping—this prevents the custard from melting.
Prepare the Oat Topping
In a small bowl, combine the 1.5 cups old-fashioned oats, 0.5 cup light brown sugar, and 0.5 cup chopped walnuts. Stir in 2 tablespoons of the cooled banana custard to help the topping stick to the pie. Spread this mixture evenly over the cooled pie, pressing down gently with a fork to create a crunchy, caramelized topping.
Return the pie to the oven and bake for an additional 10-12 minutes, until the topping is golden brown and crispy. Watch it closely—the oats burn easily. Let the pie cool completely before slicing. The contrast between the creamy custard, fresh bananas, and crunchy oat topping makes every bite irresistible.
Pro Tips For Making Old Fashioned Banana Cream Pie
- Cook Bananas First: Sauté those bananas in butter and sugar before adding the flour—this caramelizes them into tiny sweet pockets. I learned this the hard way: dry-mixing everything just makes a bland, mealy filling. A quick 3-4 minutes on medium heat builds flavor that no amount of mixing later can match.
- Use Light Brown Sugar: Light brown sugar’s moisture keeps the crust crisp but not brittle, while the molasses adds subtle depth. Dark brown sugar? It’ll make your crust tough and the filling cloyingly sweet. Trust me, the extra 5 cents for light brown sugar saves you from a dry, sad pie.
- Chill the Filling: Let the banana cream mixture sit in the fridge for at least 2 hours before baking. Cold filling thickens properly, prevents cracking, and ensures that gorgeous, jiggly texture. I used to rush this, and my pies always ended up with a sad, sunken center—your future guests won’t notice if you skip it, but you will.
- Brush Crust Edges: Dampen a pastry brush with water or milk and swipe it along the crust’s rim before adding the filling. This creates a seal that keeps the custard from leaking into the crust during baking. Yes, it’s an extra step, but it’s the difference between a pie that looks homemade and one that looks like it came from a bakery.

Frequently asked questions
Can I make this pie without a vanilla bean?
Use 2 teaspoons of pure vanilla extract instead. For even better flavor, simmer the extract with 1 teaspoon of sugar for 2 minutes to mimic the bean's depth. The custard will still be delicious, though slightly less complex than with real vanilla.
How do I prevent the banana filling from getting too runny?
Cook the bananas until they're just thick enough to coat the back of a spoon, then cool them completely before mixing with custard. For extra stability, add 1 tablespoon cornstarch to the banana mixture while cooking. Also, ensure your custard reaches 160°F but doesn't boil—this creates the perfect set without being watery.
Can I prepare the banana filling ahead of time?
Yes! The banana filling keeps well in the fridge for 3 days or freezes for 3 months. Reheat gently on the stove with a splash of milk if it thickens too much. The custard should be made fresh before assembling, but you can prep the oat topping 1 day ahead and store it separately. This makes pie assembly a breeze on busy days.
What's the best way to store leftovers?
Store slices in an airtight container in the fridge for 4-5 days. For longer storage, freeze individual slices wrapped tightly in plastic wrap. Thaw overnight in the fridge—the custard will soften slightly but still taste amazing. Reheat slices briefly in the microwave if you prefer them warm.
Is there a gluten-free version of this pie?
Certainly! Use a gluten-free pie crust and replace the all-purpose flour in the banana filling with 1 tablespoon cornstarch. For the oat topping, ensure your oats are certified gluten-free. The custard remains unchanged as it's naturally gluten-free. This version maintains all the classic flavors while being allergy-friendly.
