What Is Mango Oatmeal Crumble?

Mango oatmeal crumble is a baked dessert made by layering fresh mango slices with a lightly sweetened filling and topping it with a crumbly mixture of oats, flour, butter, and sugar. As it bakes, the mangoes become soft and juicy, while the oat topping turns golden and crisp. Unlike heavy cakes or pastries, this crumble feels lighter and fruit-forward, making it a great option when you want something sweet but not overwhelming.

Ingredients You’ll Need

For the Mango Filling:

  • 3 cups ripe mango, peeled and diced
  • 2 tablespoons brown sugar or coconut sugar
  • 1 tablespoon lemon or lime juice
  • 1 teaspoon vanilla extract
  • 1 teaspoon cornstarch (optional, for thickening)

For the Oatmeal Crumble Topping:

  • 1 cup rolled oats
  • 1/2 cup all-purpose flour (or whole wheat flour)
  • 1/3 cup brown sugar
  • 1/2 teaspoon cinnamon
  • Pinch of salt
  • 1/3 cup cold butter, cubed (or coconut oil for vegan option)

Step-by-Step Instructions

Step 1: Prepare the Mango Filling

Preheat your oven to 180°C (350°F). In a mixing bowl, combine diced mango, brown sugar, lemon juice, vanilla extract, and cornstarch. Toss gently until the mango is evenly coated. Transfer the mixture to a lightly greased baking dish and spread it into an even layer.

Step 2: Make the Oat Crumble

In a separate bowl, mix rolled oats, flour, brown sugar, cinnamon, and salt. Add cold butter cubes and use your fingers or a pastry cutter to rub the butter into the dry ingredients until the mixture resembles coarse crumbs.

Step 3: Assemble the Crumble

Sprinkle the oat mixture evenly over the mango filling. Don’t press it down too firmly, this helps create a crispy, crumbly texture.

Step 4: Bake

Bake uncovered for 35–40 minutes, or until the topping is golden brown and the mango filling is bubbling around the edges.

Step 5: Cool and Serve

Remove from the oven and let the crumble rest for 10–15 minutes before serving. This allows the filling to set slightly and enhances the flavor.

  • Use ripe but firm mangoes for the best texture
  • Cold butter creates the crispiest crumble topping
  • Add nuts like almonds or walnuts for extra crunch
