- Cinnamon: the oat streusel is lightly spiced with cinnamon.

Variations & Substitutions
- Feel free to swap out ground cinnamon for other spices. Ginger, nutmeg and cardamom would be delicious in the crumble topping!
- You'll want to use a slightly tart apple here, but you could do half granny smith and half honeycrisp apples or fuji apples.
- Swap out the light brown sugar for dark brown sugar.
- I haven't tried this recipe with frozen blueberries but it should work, just don't thaw them beforehand.
Step by Step Instructions
Step 1: Preheat your oven to 350°Fahrenheit/175°Celsius and butter a 9-inch pie dish. In a medium bowl, combine all of the dry ingredients for the streusel. Add the cubed unsalted butter and use your hands to mix everything together. Place in the fridge.
Step 2: In a large bowl, combine all of the filling ingredients. Make sure the fruit is evenly covered with the cornstarch.
Step 3: Pour the filling into the prepared pie dish and make sure it is an even layer.
Step 4: Take the streusel out of the fridge and sprinkle over the top of the filling. Bake in the oven for 40-45 minutes, you should see the fruit bubbling! Let sit for 15-20 minutes so it can set slightly before serving.
Expert Tips & Tricks
- When dicing the peeled apples, try and keep them around the same size. That way they'll bake evenly in the oven.
- Usually in baking recipes I say to take out your ingredients so everything is at room temperature, but here you will want the butter to be cold.
- Use rolled oats or whole oats, not instant oats. Instant oats will give you a powdery crumble topping.
- Place a lined baking sheet under the crisp to catch any fruit juice drips.
- Add a small handful of chopped pecans or walnuts to the streusel if you want a crunchy oat streusel!
- If you have a deep dish pie plate, you can add an extra 1 cup of diced apples to the filling.
Frequently Asked Questions
A crumble and a crisp are essentially same thing - a baked fruit filling topped with an oat streusel. A crumble is the name usually used in the UK, while a crisp is what is used in North America. Crumbles in the UK don't always have oats in the topping though!
To make this blueberry and apple crumble dairy free, just use vegan butter!
I prefer using a tart apple like a Granny Smith, but you can also use honey crisp apples, fuji apples or gala apples.
The oat topping will be a golden brown and the fruit juices will be bubbling.
Once cooled, place the covered baking dish in the fridge for up to 5 days. I recommend reheating in the microwave before enjoying.
