This blackberry crumble is perfectly sweet with an irresistible crumb topping! Slightly sour fresh blackberries are balanced out with a touch of sugar, then topped with a buttery oat crumble. Serve this blackberry crumble warm with a scoop of cold vanilla ice cream for a delicious summertime (or anytime) dessert!

What Makes This Recipe So Good

  • It’s sweet, but not too sweet! This recipe has just the right amount of sugar to sweeten everything up while still allowing that delicious fresh blackberry flavor to shine through.
  • It’s the perfect way to enjoy blackberry season! Blackberries peak in the summer months, specifically June and July, and grow abundantly in many states. Visit your local farm for a few pints of their freshest blackberries and turn them into this delicious crumble before the season’s over!
  • It’s super easy to make! With just a few simple ingredients, you’ll toss together the filling, then the crumb topping and pile everything together in a baking dish. Transfer it all into the oven and allow the magic to happen! In 45 minutes you’ll return to a perfectly baked and incredibly delicious summertime dessert.

Key Ingredients

Blackberries – This delightful berry is juicy, sweet, and just a tiny bit tangy. Blackberries will taste a tad more sour earlier in the season (think May/June), then turn much sweeter towards the end of their growing season (July/August). Give your blackberries a taste before adding them to this recipe and adjust the amount of sugar as you see necessary. Super sweet blackberries? Try just 1/4 cup of sugar in the filling. Very sour blackberries? Then add a couple extra tablespoons of sugar!

Oats – Any type of oat will work in this blackberry crumble recipe. I used and prefer rolled oats, however quick oats, or even old-fashioned oats will bake up just as delicious! Rolled oats and old-fashioned oats are thicker and heartier than quick oats.

Chef’s Tips

  • Leave this blackberry crumble to cool for about 20 minutes before serving. The blackberry filling will thicken while it cools which is necessary for the integrity of this dessert. Feel free to wait even longer before serving, though I prefer this delicious dish slightly warm with a scoop of melty vanilla ice cream!
  • Make this recipe even easier on yourself by using the same bowl to mix together both the filling and the topping. There’s no need to use two separate bowls here when all ingredients end up in the same baking dish anyway!
  • Feel free to add in any other berries you’d like to this blackberry crumble! A handful of fresh blueberries or some fresh sliced strawberries would make delicious additions to this dessert recipe.

Notes

  • Blackberries: Be sure to use fresh, not frozen, blackberries in this recipe. If frozen is your only option, you’ll need to increase the flour to about 1/2 cup to compensate for the additional liquid they will release when baked.
  • Make it Vegan: Use vegan butter or coconut oil in place of the melted butter.
  • Make it Sugar-Free: Use your favorite sugar-free replacement, such as granular Swerve and Brown Swerve, in place of the sugar and brown sugar.
