Blackberry And Apple Crumble

An easy blackberry apple crumble recipe made with fresh blackberries, sweet-tart apples, and a buttery crumble topping. This fruit dessert is gluten-free, dairy-free, nut-free, and vegan.

This fruit crumble recipe is a quick and easy summer dessert that falls somewhere between a crisp, crumble, and a cobbler with its jammy fruit filling and crunchy oat crumble topping.

There’s nothing quite like in-season, fresh blackberries. This berry has a relatively short shelf life though, so a great way to enjoy it longer is to make a blackberry dessert.

Ingredients

  • Blackberries – use fresh berries if they’re in season. Otherwise, frozen berries will also work, just thaw them first.
  • Apples – when it comes to desserts, tart granny smith apples work well to balance out the other sweet flavors, but you can use any variety of apples such as gala apples, golden apples, pink lady, etc. Use this apple guide as a reference to help you decide.
  • Brown sugar – I used light brown sugar for both the filling and the crumble topping.
  • Ground cinnamon – provides a warm, sweet, earthy flavor.
  • Lemon juice – for brightness and some acidity to cut through the sweetness.
  • Cornstarch – to thicken the fruit mixture.
  • Rolled oats – for the best texture, use old-fashioned rolled oats, not instant oats. Use certified gluten-free oats if needed.
  • Cold butter – use either vegan butter or regular unsalted butter if not dairy-free. This is what creates that beautiful golden brown crumb.
  • Brown rice flour – for the crunchy topping. I love this brand for its super fine texture.
  • Kosher salt – just a pinch to balance the flavors.

How to Make Blackberry Apple Crumble

Step 1. Prepare the fruit filling. Peel, core, and cut the apple into thin slices (roughly ¼-inch thick). Add the sliced apples to a large bowl along with the blackberries, 2 tablespoons brown sugar, ground cinnamon, lemon juice, and cornstarch.

Step 2. Transfer the apple mixture to your baking dish or skillet and spread it into a somewhat even layer.

Step 3. In a medium bowl, prepare the dry ingredients. Combine flour, rolled oats, brown sugar, and salt. Add the cold butter, pressing it through the mixture with your hands until you have a crumbly texture. 

Step 4. Spoon the oat crumble topping over the filling and bake uncovered for 45 minutes. Allow it to cool down for a few minutes. Serve with a scoop of vanilla ice cream if desired.

How can you make this apple blackberry crumble using what you already have? Here are some ideas

  • No cornstarch? – use tapioca flour/starch instead.
  • No butter? – use refined coconut oil for no coconut taste.
  • No blackberries? – you can also use other seasonal fruits such as cherries, cranberries, raspberries, or pears.
  • No brown sugar – use white sugar, cane sugar, or coconut sugar instead.
  • No brown rice flour? – substitute plain flour.
  • Add-ins – vanilla extract, ground nutmeg, etc.
  • Add chopped nuts – a handful of chopped pistachios, almonds, walnuts, or pecans would add a nice nuttiness.

Frequently Asked Questions

Is a crumble the same as a crisp? 

Crumbles are more widely associated with the UK, whereas crisps are a popular dessert in the United States. Both use a combination of flour, sugar, and butter for the crumbly streusel-like topping. Crisps also use oats in the topping, but you’ll find some crumble recipes do too (like this recipe).

How do you store leftover crumble? 

Let it cool completely and then cover with plastic wrap or aluminum foil and store it in the fridge for up to 5 days. To prevent the topping from getting soggy in this time frame, I recommend not transferring it to an airtight container and just keeping it in the dish it’s already in.

Can you freeze blackberry apple crumble? 

Yes. For a baked crumble, allow it to cool completely, and then cover it tightly with plastic wrap and foil. Place it inside a freezer-safe bag where it’ll keep for up to 3 months.

For an unbaked crumble, freeze the filling and the crumble in separate airtight containers. When ready to bake, let them thaw for a few minutes, then transfer to a baking dish and add an additional 5-10 minutes of cook time if needed.

Notes

If using tart apples such as granny smith, bump up the brown sugar in the topping from 1/3 cup to 1/2 cup. With sweeter apples such as gala, fuji, etc, I find that 1/2 cup makes it too sweet.
