Ingredients You’ll Need
Each ingredient in this Raspberry Apple Pie with Oatmeal Crumble Recipe brings something special to the party — from the tart apples to the luscious raspberries and the buttery crumble topping. Picking fresh apples and good-quality frozen raspberries really pays off in flavor.
- Granny Smith apples: Their tartness holds up well while baking and balances the sweetness from the raspberries.
- Frozen raspberries: Easily available year-round and provide that perfect juicy burst without overwhelming moisture.
- Tapioca: This is a secret thickener that keeps your pie filling delightfully gooey without being runny.
- Granulated sugar: Just enough sweetness to enhance the fruit’s natural flavors without cloying.
- Ground cinnamon: Adds warmth and a cozy aroma, the classic spice for any apple dessert.
- Ground nutmeg: Just a pinch gives subtle depth and complexity to the filling.
- Vanilla extract: A splash lifts all the flavors and rounds out the spices beautifully.
- Old fashioned oats: For the crispy, hearty crumble — avoid quick oats to keep that texture.
- Brown sugar: Brings caramel notes to the crumble topping.
- All-purpose flour: Helps bind the crumble together just right.
- Butter: Cold and cubed — essential to create those flaky, pea-sized pieces in your crumble.
- Brown Sugar Pecan Graham Cracker Crust: Pre-made crust adds a nutty, buttery base and saves you time.
Variations
I love to switch things up depending on the season or what I have on hand — this Raspberry Apple Pie with Oatmeal Crumble Recipe is versatile enough for you to play with, so don’t hesitate to get creative and make it your own.
- Use fresh raspberries when in season: They add an even brighter flavor and juiciness to the filling.
- Gluten-free crust and flour: Swap the crust and all-purpose flour for gluten-free alternatives to make this pie friendly for gluten sensitivities.
- Add chopped pecans to the crumble: I’ve done this to boost the crunch and add a toasty nutty flavor that complements the pecan crust perfectly.
- Replace tapioca with cornstarch: If you don’t have tapioca, cornstarch works well — just use a bit less to avoid gummy filling.
How to Make Raspberry Apple Pie with Oatmeal Crumble Recipe
Step 1: Prepare the Brown Sugar Pecan Graham Cracker Crust
Start by making your Brown Sugar Pecan Graham Cracker Crust as directed. I like to press it firmly into a 9-inch pie plate to ensure it’s even in thickness. Let it cool completely before adding the filling — this helps keep the crust from turning soggy once the fruit goes in.
Step 2: Mix the Raspberry Apple Filling
In a large bowl, stir together the tapioca, granulated sugar, cinnamon, nutmeg, and vanilla. Toss in the sliced Granny Smith apples and frozen raspberries, gently folding everything to combine. Let this sit for 15 minutes so the tapioca can start absorbing the juices — this little wait is key for a thick, luscious filling.
Step 3: Make the Oatmeal Cookie Crumble Topping
Combine the oats, brown sugar, flour, and cinnamon in a food processor and pulse to blend. Add the chilled butter cubes and pulse until the mixture clumps into pea-sized crumbs. Don’t overprocess; you want a coarse texture that will bake into a crisp, flavorful topping.
Step 4: Assemble and Bake
Pour your raspberry apple filling into that cooled crust and mound it up a bit. Then generously sprinkle the oatmeal crumble evenly over the top—it seems like a lot, but it bakes down beautifully. Pop it in the oven at 350°F (175°C) for about 60-70 minutes. I check it around 40 minutes to see if the crust edges need shielding with foil to prevent over-browning.
Step 5: Cooling and Serving
Once baked, let the pie cool completely before slicing. This resting time really helps the filling set up so you get clean slices loaded with that cozy fruit mixture and crunchy topping.
Pro Tips for Making Raspberry Apple Pie with Oatmeal Crumble Recipe
- Don’t Skip the Tapioca: I used to struggle with runny fillings until I discovered tapioca — it’s a game changer for that perfect thickness.
- Chill the Butter for Crumble: Cold butter yields those crunchy pockets in the topping, so keep it in the fridge until last minute.
- Cover Pie Edges Early: I learned that foil shields the crust from burning, especially around the 40-minute mark when the topping is golden but edges get dark quickly.
- Let It Cool Fully Before Slicing: Cutting too soon makes the filling spill out — patience pays off with neat and beautiful slices.
How to Serve Raspberry Apple Pie with Oatmeal Crumble Recipe
Garnishes
I love topping each slice with a scoop of vanilla ice cream — it melts just right into the warm pie and adds creaminess. Sometimes I sprinkle a little extra cinnamon or chopped toasted pecans on top for a bit of extra crunch and flavor that complements the oatmeal topping beautifully.
Side Dishes
This pie shines as a dessert on its own, but I’ve also served it alongside lightly sweetened whipped cream or paired it with a cup of hot spiced tea for cozy afternoons at home.
Creative Ways to Present
For special occasions, I’ve baked this pie in individual ramekins topped with crumble for personal servings — so festive and fun! Another time, I placed edible flowers around the crust edge for a soft, charming look that impressed all my guests.
Make Ahead and Storage
Storing Leftovers
I usually cover leftover pie tightly with plastic wrap or foil and store it in the refrigerator, where it keeps well for up to 4 days. The flavors actually deepen overnight — so sometimes it tastes even better the next day!
Freezing
I’ve frozen whole or sliced leftover pie by wrapping it carefully in plastic wrap followed by foil. When thawed slowly in the fridge, the texture stays pretty close to fresh — perfect for making ahead during busy holiday seasons.
Reheating
To warm up leftovers, I pop slices in a low oven around 300°F for 10-15 minutes or until heated through. Avoid microwaving too long as it can make the crust soggy. A light warmed slice with cold ice cream? Pure bliss.
FAQs
-
Can I use fresh raspberries instead of frozen in the Raspberry Apple Pie with Oatmeal Crumble Recipe?
Absolutely! Fresh raspberries work beautifully, especially in season. Just be mindful they may add a bit more moisture, so you might want to slightly increase the tapioca or reduce other liquids to keep the filling thick.
-
What if I don’t have tapioca—can I substitute something else?
If tapioca isn’t on hand, cornstarch is a good alternative. Use about half the amount and mix it well with the sugar before adding the fruit. This will help thicken the filling without making it gummy.
-
How can I prevent the crust edges from burning?
Check the pie about 40 minutes into baking. If the edges are browning too fast, cover them with strips of foil or a pie shield. This way, the crust bakes evenly without burning while the filling cooks through.
-
Is it better to serve this pie warm or cold?
Both ways are fantastic! Warm pie is comforting and pairs wonderfully with a scoop of ice cream, while chilling helps the filling set nicely for clean slices and a firmer texture.

Instructions
- Prepare the crust: Prepare one Brown Sugar Pecan Graham Cracker Crust according to directions. Let it cool completely before adding any filling.
- Mix the filling: In a large bowl, whisk together the tapioca, sugar, cinnamon, nutmeg, and vanilla. Add the peeled and sliced Granny Smith apples and frozen raspberries, tossing gently to combine. Allow the mixture to stand for 15 minutes to thicken slightly.

Notes
- Cover the crust edges with foil halfway through baking to avoid over-browning.
- Frozen raspberries can be used directly without thawing to prevent the filling from becoming too watery.
- Make sure the butter for the crumble topping is well-chilled to create a crisp and tender topping.
- Allowing the filling to stand with tapioca before baking helps thicken the juices for a better texture.
- This pie can be served warm or at room temperature, optionally with whipped cream or vanilla ice cream.
