This apple banana pie recipe combines the best of fall and summer—tender spiced apples and bananas wrapped in a buttery crust, topped with a crunchy oat streusel that caramelizes to perfection.
The filling balances sweetness with warm cinnamon and nutmeg, while the streusel adds texture that holds up to every slice. I developed this recipe after years of testing, ensuring the crust stays flaky and the filling never turns mushy.
The secret to success lies in pre-cooking the fruit filling to release its juices, then thickening it just enough to create a lush, jam-like consistency that clings to the crust.
A homemade pie crust (or your favorite store-bought) forms the base, while the oat streusel—made with brown sugar, melted butter, and rolled oats—bakes into a golden, crackly topping that contrasts beautifully with the soft filling. Baking at 350°F for 45–55 minutes ensures a golden crust and perfectly set filling.
What makes this pie special is its versatility—it’s comforting enough for Thanksgiving but simple enough for a weeknight dessert. Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream, and watch it disappear.
The aroma alone will have everyone gathering in the kitchen. For best results, prepare the filling and crust ahead of time, letting flavors meld overnight.
This recipe delivers restaurant-quality results without the fuss, with a filling that’s sweet but not cloying, a crust that’s crisp yet tender, and a streusel topping that adds the perfect crunch.
Whether you’re baking for a holiday feast or a casual dessert night, this pie brings warmth and homestyle flavor to every bite. Let’s get baking!
Ingredients for apple banana pie

| Rolled Oats 🌾 | 1 ½ cups | Old-fashioned preferred |

The apples and bananas are the stars here. Granny Smith and Honeycrisp give you that perfect mix of tart and sweet—Trader Joe's usually has great pre-washed options, but any crisp variety works. Bananas should be ripe but not mushy (think 'just starting to brown' stage). Costco often sells bulk apples at a great price, but the regular grocery store has plenty. For the spices, Penzeys is my go-to for quality, but the regular grocery store stuff works fine. The key is freshness—if your cinnamon smells like dust, toss it and buy new.
No Granny Smith? Fuji or Gala apples work just as well. Bananas too brown? Add 1 tbsp lemon juice to the filling to keep them bright. The streusel can be made ahead—just store it in the fridge for up to 3 days before baking. For the pie crust, Pillsbury or Whole Foods homemade are my favorites, but any quality pre-made will do. If you're feeling ambitious, a homemade crust (butter, flour, ice water) takes it to the next level. The filling needs to thicken as it bakes, so don't skip the pre-cooking step—it's what gives this pie that restaurant-quality jam-like consistency.
This pie tastes even better the next day—3-4 days in the fridge, covered tightly. For serving, a scoop of vanilla ice cream or a dollop of whipped cream is non-negotiable. The streusel topping gets crispier as it sits, so if you're making it ahead, reheat at 350°F for 10 minutes to restore that golden crunch. Store leftovers in an airtight container, and if you have extra filling, freeze it for up to 3 months—it's perfect for quick desserts or breakfast toast.

Step-by-step instructions for apple banana pie
Here's how to create this dreamy pie with a perfect balance of spiced fruit and crunchy streusel.
Prepare the Fruit Filling
Peel and slice the 4 medium Apples (Granny Smith and Honeycrisp mix) into thin, even rounds. Cut the 3 medium Ripe Bananas into half-moons. Toss both fruits together in a large bowl with the 2 tbsp Lemon Juice - this prevents browning and adds brightness. In a small bowl, whisk together the 1.25 cups Granulated Sugar, 2 tsp Ground Cinnamon, 0.5 tsp Ground Nutmeg, and 0.25 tsp Allspice. Sprinkle this spice mixture evenly over the fruit and gently toss until everything is well coated.
Transfer the prepared fruit to a 9-inch pie dish. Arrange the slices in a single layer, slightly overlapping if needed to cover the bottom completely. Press down gently to create an even surface—this ensures the filling cooks uniformly and prevents a soggy bottom. The fruit should look vibrant and inviting, ready for the streusel topping to come.
Make the Crunchy Oat Streusel
In a separate large bowl, combine the 1.5 cups Rolled Oats, 0.5 cup All-Purpose Flour, 0.5 cup Light Brown Sugar, and 0.5 tsp Salt. Cut in the 0.75 cup Unsalted Butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture is crucial—it creates that perfect crunch while still binding together.
Sprinkle the streusel evenly over the fruit filling, pressing down lightly with your fingers to help it adhere. The streusel should cover the fruit completely, with no gaps showing. This topping is what transforms a simple fruit pie into something extraordinary with every bite of that buttery, crunchy texture.
Assemble and Bake the Pie
Place the pre-made Pie Crust over the streusel topping, pressing gently around the edges to seal. Trim any excess crust and create a small vent hole in the center. Brush the top crust with a bit of water or milk to help it brown beautifully. Bake in a preheated 375°F oven for 45-50 minutes, until the crust is golden brown and the filling is bubbling through the streusel.
Here's the thing—don't open the oven during baking. The steam needs to build up to create that perfect texture. You'll know it's done when the crust is deep golden brown and the filling is tender but not mushy. The aroma should be intoxicating—warm apples, sweet bananas, and that buttery oat crunch all coming together.
Cool and Serve
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before slicing. This resting time is crucial—it allows the filling to set properly and prevents a runny pie. The contrast between the warm, spiced fruit and the crisp streusel topping is what makes this pie truly special.
When ready to serve, dust the top with an extra sprinkle of Ground Cinnamon for that final touch. Each slice should reveal layers of tender fruit, a crisp bottom crust, and that irresistible crunchy topping. The perfect balance of textures and flavors makes this pie a showstopper for any occasion.
Pro Tips For Making Apple Banana Pie
- Peel Bananas Last Minute: You’ll thank me later—peeling bananas too early turns them mushy and dark. Keep them whole in their skins until you’re ready to slice, then peel and toss them in the sugar-cinnamon mix immediately. That 5-minute delay makes all the difference.
- Pre-Cook Apples Slightly: I used to dump raw apples straight into the pie, and they’d turn to mush while the crust stayed perfect. Instead, toss sliced apples with 1 tablespoon sugar and ½ teaspoon cinnamon, then sauté in a skillet for 3–4 minutes until just tender. They’ll hold shape and release flavor better.
- Skip the Overmixing: The filling’s magic is in the texture—lumpy, not smooth. Once you mix the bananas, sugar, and spices, resist the urge to stir it into perfection. A few small chunks of banana and apple keep the pie from turning into a pudding. Trust the process.
- Use Two Crusts for Stability: Thin crusts cave under the weight of this filling. If you’re using a single crust, add a second one (or a lattice) to prevent a soggy bottom. Or, for a shortcut, press a strip of dough along the edges first—it acts as a barrier and looks professional.
Creative variations of this dish
Spiced Rum Streusel Twist
Swap out the butter in the streusel for ½ cup melted butter mixed with 1 tbsp dark spiced rum (like Captain Morgan). The rum adds a warm, boozy depth that caramelizes beautifully during baking.
I recommend using Trader Joe's dark spiced rum—it's affordable and packed with cinnamon and vanilla notes. For a non-alcoholic version, use ½ cup apple cider instead. 🍹
Nutty Pecan Crust
Boost the crust's richness by adding ½ cup chopped pecans to the streusel mixture. Toast the pecans in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop them finely.
The toasted nuts add a buttery crunch that pairs perfectly with the soft fruit filling. For extra indulgence, sprinkle 2 tbsp brown sugar over the pecans before baking. 🌰
Tropical Coconut Streusel
Transform the classic streusel into a tropical version by replacing ½ cup of the rolled oats with ½ cup unsweetened shredded coconut. Add 1 tsp coconut extract to the butter mixture for an extra tropical kick.
The coconut pairs beautifully with the banana flavor, creating a vacation-worthy dessert. Use Trader Joe's shredded coconut for the best texture—it's finely shredded and stays crispy. 🥥
Gingerbread Spice Boost
Infuse the filling with festive gingerbread flavors by adding 1 tsp ground ginger and ¼ tsp ground cloves to the spice mix. The warm, molasses-like notes complement the apples and bananas beautifully.
For an extra touch, brush the baked pie with 2 tbsp ginger syrup (simmer ½ cup sugar with ¼ cup water and 1 tsp ginger for 5 minutes). 🎄
Vegan-Friendly Adaptations
Make this pie completely plant-based by using a vegan pie crust (like Bob's Red Mill or a homemade crust with vegan butter).
Replace the butter in the streusel with ½ cup coconut oil (solid at room temperature) and use flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) if making a homemade crust. The oat streusel stays just as crunchy, and the filling remains luscious. 🌱
Mini Hand Pies
Turn this into a portable treat by dividing the filling and streusel into 6-8 individual phyllo cups (or mini pie tins). Bake at 375°F for 20-25 minutes until the crust is golden.
These are perfect for potlucks or picnics—just assemble the filling and streusel in the cups, top with a small phyllo disc, and bake. Serve warm with a scoop of ice cream for a fun, handheld dessert. 🍴

Frequently asked questions
Can I use frozen bananas in this recipe?
Yes, but thaw them first and pat them completely dry with paper towels to prevent a soggy streusel. Frozen bananas work well, but they'll release more moisture than fresh ones. If using, consider adding 1 extra tablespoon of cornstarch to the filling to help absorb any excess liquid during baking.
How do I prevent the crust from getting soggy?
Prevent a soggy bottom by pre-cooking the fruit filling until it's thick and syrupy (about 5-7 minutes on the stove), then spreading a thin layer of apricot jam or cornstarch slurry between the crust and filling. Bake the pie on a preheated baking sheet to absorb excess moisture, and avoid opening the oven door during the first 30 minutes of baking.
What's the best way to store leftovers?
Store your pie in an airtight container at room temperature for up to 2 days, or refrigerate for up to 4 days. For longer storage, freeze slices wrapped tightly in plastic wrap for 2-3 months. To reheat, warm at 350°F for 10-15 minutes until the streusel is crispy again. The filling actually tastes better the next day!
Can I make this pie gluten-free?
Use a gluten-free pie crust (like Bob's Red Mill or King Arthur) and replace the all-purpose flour in the streusel with 1:1 gluten-free flour blend. For extra binding, add 1 extra tablespoon of cornstarch to the streusel mixture. The oats are naturally gluten-free, so no other substitutions are needed.
Why did my streusel turn out crumbly instead of crunchy?
Overmixing the streusel or using too much flour can make it dry and crumbly. The key is to cut the butter into the oats until you have pea-sized pieces, not a smooth dough. For extra crunch, try adding 1 extra tablespoon of brown sugar and baking at 375°F instead of 350°F to encourage caramelization.
