Ingredients

2 cups fresh mulberries, rinsed and drained (about 300 g)
1/4 cup granulated sugar (50 g)
1 tablespoon all‑purpose flour (8 g)
1/2 teaspoon ground cinnamon (1 g)
1/4 teaspoon salt (1 g)
1/2 cup rolled oats (40 g)
1/4 cup all‑purpose flour (32 g)
1/4 cup packed light brown sugar (50 g)
1/4 cup cold unsalted butter, diced (57 g)
1 teaspoon vanilla extract (optional)

How to Make Mulberry Crumble

Preheat your oven to 375°F (190°C). Grease a 9‑inch square baking dish with a light dusting of butter or non‑stick spray.
Prepare the berry filling: In a medium bowl, gently toss the mulberries with 1/4 cup sugar, 1 tablespoon flour, cinnamon, and salt. The flour helps thicken the juices as the berries bake. If you like a hint of vanilla, stir in the vanilla extract now.
Spread the berries: Transfer the mixture into the prepared dish, spreading it out evenly.
Make the crumble topping: In a separate bowl, combine the rolled oats, 1/4 cup flour, brown sugar, and salt. Add the cold butter pieces and use your fingertips or a pastry cutter to blend until the mixture resembles coarse crumbs.
Top the berries: Sprinkle the crumble mixture evenly over the fruit layer.
Bake: Place the dish in the oven and bake for 30–35 minutes, or until the topping is golden brown and the berries are bubbling.
Cool slightly: Remove from the oven and let the crumble rest for 5 minutes before serving. This allows the juices to thicken a bit more.
Serve: Scoop onto plates and enjoy warm, or let it cool to room temperature for a comforting dessert. A scoop of vanilla ice cream or a dollop of whipped cream makes it extra special.

Tips for Best Results

Use the freshest mulberries you can find; they’re the star of the dish.
If your berries are very juicy, add a teaspoon of cornstarch instead of flour to thicken the filling.
For a crunchier topping, toast the oats in a dry skillet for 2 minutes before mixing.
Keep the butter cold; it creates a flakier crumble.
Feel free to add a pinch of nutmeg or allspice for extra warmth.

Variations

Berry Mix‑Up: Swap mulberries for blueberries, raspberries, or a mix of summer berries.
Nutty Crumble: Add 1/4 cup chopped walnuts or pecans to the topping.
Gluten‑Free: Use a gluten‑free flour blend and gluten‑free oats.
Vegan Version: Replace butter with coconut oil and use a plant‑based brown sugar.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave for 30–45 seconds or warm in a 350°F oven for 10 minutes. The crumble will stay crisp, and the berries will stay juicy.
