Ingredients you’ll need
This strawberry apple crumble uses simple, whole-food ingredients for a sweet, jammy filling and a crunchy oatmeal topping. See the recipe card below for exact measurements.
- Strawberries: Fresh or frozen (use frozen without thawing) for a sweet base.
- Apples: A mix of a sweet variety like Honeycrisp or Pink Lady and a tart variety like Granny Smith gives the best texture and flavor.
- Coconut Sugar: Adds a subtle caramel note to the filling and topping.
- Lemon Juice: Brightens the fruit and balances sweetness.
- Starch (tapioca, arrowroot, or cornstarch): Thickens the filling so it’s jammy, not watery.
- Rolled Oats: Use gluten-free oats if needed; they create the crunchy topping.
- Oat Flour: Helps the topping hold together and become tender.
- Nuts (optional): Walnuts, almonds, or pecans add crunch; omit for nut-free.
- Salt & Cinnamon: Enhance and balance the flavors.
- Maple Syrup: Binds and crisps the topping while adding natural sweetness.
- Coconut Oil or Butter: Melted to create a golden, tender crumble; use vegan butter to keep it dairy-free.
- Vanilla Extract: Adds warmth and depth to the crumble topping.

How to make strawberry apple crumble
Follow these simple steps for a reliably delicious crumble. The method is straightforward and great for cooks of any level.
Step One: Preheat the oven to 375°F and lightly grease an 8×8-inch baking dish, 9-inch pie dish, or cast-iron skillet. Set aside.
Step Two: In a large bowl, toss strawberries, cubed apples, coconut sugar, lemon juice, lemon zest, vanilla and starch until the fruit is evenly coated. Transfer the filling to the prepared dish.

Step Three: In another bowl, combine rolled oats, oat flour, chopped nuts (if using), coconut sugar, salt and cinnamon. Add maple syrup, melted coconut oil (or butter) and vanilla, then mix with your hands until the mixture clumps slightly.

Step Four: Spread the oat crumble evenly over the fruit filling.
Step Five: Bake for 32–42 minutes, until the topping is golden and crisp and the fruit filling is bubbly and tender. I usually bake mine about 40 minutes. Let the crumble cool for 10–15 minutes so the filling sets slightly before serving.
Serve warm with vanilla ice cream, frozen yogurt, whipped cream, or a spoonful of Greek yogurt.



Top tips for the best crumble:
- Choose firm apples: Mix sweet and tart varieties like Honeycrisp and Granny Smith for the best texture.
- Bake at 375°F: This temperature yields a crisp topping and a jammy filling without becoming runny.
- Frozen strawberries work: Add frozen berries directly—no need to thaw.
- Customize the topping: Add chopped nuts or extra spices like nutmeg for more depth.
- Make it nut-free: Simply omit nuts.
- Scale up: Double the recipe for a 9×13″ pan when serving a crowd.
- Use starch: Tapioca, arrowroot or cornstarch will thicken the filling for that perfect jammy consistency.

Easy ingredient substitutions
Swap a few ingredients to suit what you have on hand, but try to keep most the same for consistent results.
- Strawberries: Use frozen (don’t thaw) or swap with peaches, raspberries, blueberries or mixed berries.
- Apples: Golden Delicious, Jonagold or Pink Lady are good alternatives.
- Nuts: Use almonds or walnuts or omit for a nut-free version.
- Coconut oil: Replace with melted unsalted butter or vegan butter.
- Oat flour: Substitute almond flour if desired.
- Coconut sugar: Use light or dark brown sugar instead.
- Starch: Cornstarch, tapioca or arrowroot all work to thicken the filling.
- Maple syrup: Honey or agave can replace maple if not vegan.
Serving suggestions
Enjoy this strawberry and apple crumble with:
- Vanilla ice cream or frozen yogurt
- Whipped cream or non-dairy whipped topping
- Greek yogurt for a tangy contrast
- A drizzle of caramel or honey
- Fresh lemon zest or mint for brightness
- Warm custard or vanilla pudding
