1/2 cup unsalted butter, plus enough to butter the baking dish
1 cup brown sugar
1/2 cup white flour (all purpose)
1 cup rolled oats
1/3 cup Walnuts, chopped [optional]
3 cups Cranberries, fresh or frozen
Vanilla Ice Cream [optional]
Preheat the oven to 350°F. Butter a 9-inch (23 cm) baking dish.
In a bowl, combine the brown sugar, flour, rolled oats, butter and nuts. Mix until crumbly.
Press half of the mixture into the baking dish. Add the cranberries. Sprinkle the other half of the crumble mixture over the cranberries.
Bake in the center of the oven until the cranberries are bubbling and the topping is golden brown, about 35-40 min. Remove the crisp from the oven and let cool at room temperature for 30 minutes.
Serve with vanilla ice cream, if desired.
