🍎Ingredients
Here are the ingredients we used for this recipe. You can find more information for substitutions below.
- Apples. Make sure to use an apple that will hold its shape when baking. You can use (almost) any kind of apples you prefer. Don’t use something like golden delicious or red delicious. They will just become mushy when cooked. We recommend using Honeycrisp, Gala, Granny Smith, Braeburn, Pink Lady, or your favorite variety that will hold up well to baking. Just be sure to peel apples with thicker skin, like Granny Smith.
- Fresh blueberries.
- All-purpose flour
- Rolled oats. Also called old-fashioned oats. This type cooks quickly but retains its shape and texture well during baking which makes it ideal for making the crumbly topping.
- Brown sugar
- Kosher salt. A bit of salt enhances the sweet and tart taste of the fruit and berries.
- Ground cinnamon
- Unsalted butter
- Lemon. We use both the lemon zest and fresh lemon juice. Lemon adds a fresh zesty flavor to the apple and blueberry filling.
- Vanilla extract

✨Substitutions
Here are a few suggestions on additional flavors to try, or simple variations to this recipe.
- Add more warm spices. Aside from cinnamon, you can also use other spices like nutmeg, cardamom, cloves, ginger, and allspice.
- Use more or different berries. If you are looking for flavor variation, you can swap the blueberries for raspberries, blackberries, strawberries, or cherries.
- Different toppings. Aside from vanilla ice cream, you can also top the portions with frozen yogurt or whipped cream.
- Apple variety. We like using sweet apples for this recipe like Honeycrisp. If you use tart apples, you may need to add a bit of extra brown sugar for more sweetness.
- Frozen blueberries. We recommend using fresh blueberries if possible for the best results, but, if using frozen fruit, you may want to add a touch more flour to the fruit filling and bake for a few minutes longer to help get rid of the extra moisture.
✨Variations
- Gluten-free. Substitute the all-purpose flour with a 1:1 gluten-free flour of your choice. We like using Bob’s Red Mill 1:1 flour (affiliate link). Always double-check if the oats you are using are also certified gluten free, because some may contain wheat, barley, or rye during manufacturing. Bob's Red Mill also creates certified gluten free oats.
- Vegan. The only ingredient you need to swap here is the butter. All you will need is some dairy-free or vegan butter.
- Lower sugar. You can reduce the amount of brown sugar in the recipe if desired. We like using Swerve Brown.
- Low-carb. In addition to reducing the sugar content, using almond flour will lower the carb count while also making the crumble gluten-free. You may also want to swap the all purpose flour in the fruit filling for cornstarch.
- Nutty. If you want to add a savory crunch to the crumble, add crushed nuts like almonds, pecans, walnuts, or macadamia nuts.
- Need single servings? Instead of a baking pan, you can place portions in ramekins and then bake. This is a great way to serve guests individually.
- Extra decadent. Try serving this with ice cream and a drizzle of homemade salted caramel for an incredible decadent bite!
🔪Prep work
- Preheat the oven to 350°F.
- Grease a large baking dish (9x13 inch) with butter or cooking spray.
- Cut the apples evenly into thin slices or small cubes. There's no need to peel unless you're using a thick-skinned apple like Granny Smith.
- Melt the butter in the microwave and set aside to cool slightly before using.
- Zest and juice the lemon.
- Measure out all remaining ingredients.

✨Pro Tip: Don't worry about the crumble mixture having a smooth consistency. We want it to have some lumps. It will create a nice crispy crumble topping!

✨Tips & tricks
- Allow the crumble to rest before serving. This gives the hot fruit time to cool down a bit and for the moisture to re-distribute and settle. That way, you don't end up with too much moisture or burning your mouth.
- Use a large, shallow baking dish. You want to make sure to use a baking dish that is not too deep, or else the liquid released from the fruit will create a wet and soupy texture. We recommend using a 9x13-inch pan for best results.
- Use the right type of apple. Make sure to use an apple that will hold its shape when baking. Don’t use something like golden delicious or red delicious. They will just become mushy when cooked. We recommend using Honeycrisp, Gala, Granny Smith, Braeburn, or your favorite variety that will hold up well to baking.
- Peel the apples if the peel is tough. We love tart and crisp granny smith apples, but please note that if using this variety it is probably best to peel it. The peel is too tough when cooked to be enjoyed. This is why we prefer using Honeycrisp for this recipe.
- Avoid a soggy fruit crisp. Make sure not to add too much moisture and follow the recipe exactly, or else you may end up with a wet and soggy mess! We also don’t recommend using frozen fruit if possible, as this can create more moisture.
