The secret to the best blueberry crumble is in the topping. I use melted butter, which makes this recipe quick and incredibly delicious.
I use blueberries in the video, but this easy crumble recipe works great with other berries and fruits!
Main ingredients
- Blueberries: I love using fresh blueberries to make this crumble, but the recipe also works great with frozen blueberries. When I use frozen berries, I thaw them, drain the excess liquid, and then use them in the recipe.
- Sugar: You will use a little sugar with the blueberries and for the crumble. Depending on how acidic the cranberries are, you may need more or less sugar. I taste them to see how tart my cranberries are and then adjust the sugar as needed.
- Lemon: I love lemon and cranberries, so I mix a tablespoon of fresh lemon juice into the filling. If you don't have lemon, use water.
- Flour and oat flakes:This is what makes our coverage fall apart. I love the combination of flour and oats because the flour helps create clumps of topping that hold together and brown in the oven. For a gluten-free crumble, use your favorite gluten-free flour blend and certified gluten-free oats.
- Butter:Other blueberry crumble recipes ask you to add cold butter to the flour and oats. We do not use cold butter. Instead, we use melted butter, which is easier, less messy, and makes a better topping (we use the same process when making crisp apple). For the vegan blueberry crumble, use plant-based butter.
How to make blueberry crumble
First, you will make the blueberry filling.I keep it simple, using sugar, flour, lemon juice and a pinch of salt. Mix it all together and then pour it into a cake or small baking dish.
For the crumble topping, mix the flour with the rolled oats, sugar and salt, then pour in a stick of melted butter. Melted butter is quicker and less messy than cold butter, and it makes a much better crumbly topping, too.
By using melted butter, the flour and oats are coated in delicious butter, which helps them stay on top of the blueberries. After baking, the topping resembles golden crumbs with just enough crunch to stand up to the dreamy blueberry filling beneath.
I bake my crumble until the juices thicken slightly and the topping turns a light golden color. Then I let it cool for 10 minutes before digging deeper. This blueberry crumble is amazing served with ice cream. whipped creameither whipped coconut cream.
Blueberry crumble variations
I love how simple it is to make this blueberry crumble. Here are some really delicious variations:
- You can use other types of berries to make a berry crumble (try blackberries, raspberries, currants or sliced strawberries). Remember to taste the berries before baking to see how much sugar the filling may need. More tart berries, like currants, will need a little more sugar.
- Combine blueberries with fruits such as sliced peaches, apples, or pears.
- Add spices to your crumble topping. I love 1/2 teaspoon cinnamon and a pinch of nutmeg or try 1/2 teaspoon Chinese 5 spice.
- Add walnuts to the crumble topping. I especially love almonds and cranberries together.
Tips for Storing and Prepping Ahead
Homemade blueberry crumble lasts up to 4 days in an airtight container in the refrigerator. It can also be frozen for up to 1 month.
To make blueberries crumble ahead of time, follow our recipe, but do not bake the crumble. Instead, wrap it tightly with aluminum foil (I wrap it twice) and then freeze it for up to 1 month. When you're ready to bake it, bake the frozen crumble until the filling is bubbling and the topping is golden brown (40 to 60 minutes).

Will need
Blueberry filling1 ½ pounds (680 g) fresh blueberries, about 2 pints
2 tablespoons (24 g) sugar or more to taste
2 tablespoons (18 g) all-purpose flour
1 tablespoon (15 ml) fresh lemon juice or water
A pinch of fine sea salt
Shredded topping3/4 cup (100 g) all-purpose flour
3/4 cup (65 g) old-fashioned rolled oats
1/2 cup (100 g) sugar, try a mixture of brown sugar and granulated sugar
1/2 cup (115 g) melted butter, 1 stick
1/8 teaspoon fine sea salt
Addresses
1Preheat the oven to 375°F (190ºC).
2Add the cranberries, lemon juice, 2 tablespoons flour, 2 tablespoons sugar, and a pinch of salt to a 9-inch pie plate (or use a 2-quart baking dish). Mix well until combined.
3In a medium bowl, combine flour, rolled oats, sugar and salt. Add the melted butter, then stir until the butter has moistened all of the flour and the topping is crumbly.
4Sprinkle the crumble over the blueberry filling. I use my hands to do this. As I sprinkle, I press the crumbs together to create larger clumps of topping.
5Bake until juices thicken and topping turns light golden, 25 to 35 minutes. Let cool for 10 minutes then serve.
Adam and Joanne's advice
- Frozen blueberries: Thaw frozen cranberries and drain them of excess liquid before using them in this recipe. Use slightly more frozen blueberries than fresh (about 1 ¾ pounds)
- Sugar: Before adding sugar to the filling, taste the berries. If they are too sour, add 1 to 2 tablespoons more sugar to the cranberry filling.
- Gluten-Free Blueberry Crumble: Use your favorite store-bought gluten-free flour blend instead of the all-purpose flour mentioned above. Make sure your oats are GF certified.
- Vegan Blueberry Crumble: Use plant-based butter or coconut oil.
- The nutritional data provided below are estimates. We assume 2 tablespoons of sugar for the filling.
