What Goes Into Blueberry Mango Crumble

Fresh fruit and a crunchy oat topping make this Blueberry Mango Crumble simple, sunny, and naturally sweet.

• Blueberries: Juicy and slightly tart, they balance the sweetness of the mango and turn jammy once baked.
• Fresh Mango: Softens into sweet, silky pockets that make this crumble feel bright and tropical.
• Rolled Oats: Create that crisp, golden crumble top with just the right amount of texture.
• Honey: Adds natural sweetness and helps bind the oat topping while creating caramel-like edges.

On the stove

1. Prep Fruit: Preheat oven to 350°F (175°C). Place blueberries and mango slices in an 8-inch baking dish, then add flour, sugar and vanilla. Mix well to coat evenly.

1. Make Crumble: Combine oats, flour or almond meal, shredded coconut if using, honey, melted butter, sugar and salt in a medium bowl until well mixed.

1. Assemble: Spread the crumble mixture over the fruit, making sure to fully cover up the top evenly.

1. Bake: Bake for 40 minutes, or until filling is bubbling and top is golden. Serve with ice cream or enjoy plain.

For a full dessert spread, pair it with something a little contrasting in texture or temperature. Try serving it alongside Soft Peanut Butter Cookies for a chewy, nutty counterpoint or with Nutella Hot Chocolate for a rich, cozy finish that plays beautifully with the bright fruit.

Kitchen tip

• Use ripe mangos whenever possible because they soften beautifully in the oven and help create that jammy fruit base. If your mangos are firm, slice them thinner so they cook down evenly.
• For a crispier topping, let the crumble cool for a few minutes before serving. The oats firm up as they rest and the texture becomes even better.
• Tuck a few extra blueberries on top before baking. They burst in the oven and make the crumble look extra pretty.

Recipe FAQ's

Make sure the topping fully covers the fruit and bake until the edges bubble. Letting the crumble rest for a few minutes before serving also helps the oats firm up.

If the filling seems overly juicy, allow the crumble to cool for about ten minutes. The juices will naturally thicken as it rests. Next time, you can add a little more flour to the fruit mix.

Look for bubbling fruit around the edges and a golden, crisp topping. These two signs guarantee the crumble has thickened and the oats are fully toasted.
