A delightful vegan dessert featuring a warm berry filling topped with a crunchy walnut-oat crumble.
Preheat your oven to 425°F.
Preheating ensures even cooking and a perfect texture.
In a large bowl, combine the frozen berries and cornstarch. Let it sit for about 20 minutes, stirring occasionally, until the cornstarch dissolves.
Allowing the cornstarch to dissolve ensures a smooth and thickened filling.
Divide the berry mixture evenly among six ramekins.
Using ramekins makes serving easier and more elegant.
In another bowl, mix the brown sugar, flour, oats, walnuts, and cinnamon. Add the chilled margarine and blend with your fingers until coarse crumbs form.
Using your fingers helps achieve the perfect crumbly texture.
Sprinkle the crumble mixture evenly over the berry-filled ramekins.
Ensure an even layer for consistent baking.
Bake in the preheated oven for 10 minutes. Then reduce the temperature to 350°F and bake for an additional 30 minutes, or until the topping is golden brown and the filling is bubbling.
Reducing the temperature prevents over-browning of the topping.
Allow the crisps to cool for at least 15 minutes before serving.
Cooling helps the filling set and enhances the flavors.
