Step 1

Preheat the oven to 400 (200C) degrees.

Step 2

Combine all ingredients for the topping in a bowl, using a fork or your hands to blend the mixture until it forms moist clumps.

Step 3

In a saucepan, stir together all the ingredients for the filling except for the orange zest and place over medium heat. Bring to a simmer, then cook just until the cranberries begin to soften and pop, stirring frequently. Remove from the heat and stir in the orange zest.

Step 4

Transfer the cranberry mixture to a 9-inch pie or baking dish. Sprinkle the crumble topping evenly over the cranberries.

Step 5

Bake 20 minutes, or until the juices are bubbling and the topping is golden brown.

Step 6

Serve warm or at room temperature.
