Add 5 cups cranberries to a 9x9 baking dish. Toss with 1/2 cup sugar, 1 tablespoon orange zest, 4 tablespoons orange juice, and 1 tablespoon Grand Marnier.
In small bowl, combine 1 cup all purpose flour, 1 cup sugar, 1/2 teaspoon cinnamon, and 1 large egg. Mixture will be crumbly. Cover cranberries with mixture.
Slice 6 tablespoons butter into thin slices and spread as evenly as possible on top of cobbler mixture.
Bake in preheated oven for 45-50 minutes until golden brown.
Notes
Fresh cranberries work best for this recipe but you can also use frozen cranberries. If using frozen, either allow them to thaw first or you may have to increase your cooking time a few minutes.
Fresh squeezed orange juice is best. I always zest the orange first, then squeeze the juice out.
You can add a bit of cinnamon to the fruit filling as well if you want. I almost always use pumpkin pie spice when a recipe calls for cinnamon.
The butter slices easily if it is cold.
This cranberry cobbler tastes great when served hot or cold and I'll never deny a scoop of vanilla ice cream on top!
