Equipment
- 8x8 inch baking dish
- Large mixing bowl
- Oven thermometer
- Wooden spoon or spatula
Ingredients
Berry Filling
- 3 cups mixed berries fresh or frozen blueberries, raspberries, strawberries, blackberries
- 2 tablespoons maple syrup pure maple syrup
- 1 tablespoon lemon juice freshly squeezed
- 1 tablespoon cornstarch
Crumble Topping
- 1 cup rolled oats use certified gluten-free oats if needed
- 1/2 cup almond flour
- 3 tablespoons coconut oil melted and slightly cooled
- 2 tablespoons maple syrup for the topping
- 1/2 teaspoon ground cinnamon
- 1 pinch salt
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease an 8x8 inch baking dish with a small amount of coconut oil and set aside.
- In a large mixing bowl, combine the mixed berries, 2 tablespoons of maple syrup, lemon juice, and cornstarch. Toss until the berries are evenly coated. Pour the filling into the prepared baking dish and spread into an even layer.
- In the same bowl, combine the rolled oats, almond flour, melted coconut oil, remaining 2 tablespoons of maple syrup, cinnamon, and salt. Stir until the mixture is evenly moistened and begins to clump together. It should resemble wet sand.
- Scatter the crumble topping evenly over the berry filling. Do not press it down firmly — a loose topping bakes up crispier and more golden.
- Place the baking dish in the preheated oven and bake for 28 to 32 minutes, until the topping is deep golden brown and the berry filling is bubbling visibly around the edges.
- Remove from the oven and allow the crumble to rest for at least 10 minutes before serving. This allows the filling to thicken and set, making it easier to scoop and serve cleanly.
- Serve warm with a scoop of vanilla ice cream, a dollop of Greek yogurt, or enjoy it on its own. Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
Notes
For best results with frozen berries, thaw them slightly and drain excess liquid before using to prevent a watery filling. Do not skip the cornstarch as it thickens the berry juices into a jammy, glossy sauce. Let the coconut oil cool slightly before mixing into the topping so it does not partially cook the oats. The crumble is done when the topping is a rich amber color and the fruit is actively bubbling. To make ahead, prepare the filling and topping separately, store covered in the refrigerator, and bake fresh when ready to serve.
