Preheat the oven to 350. Grease an 8x8 casserole dish or an 8 inch cast iron skillet with butter. Set aside.

In a large bowl, add pancake mix, buttermilk, vanilla, and orange zest. Stir until just combined, then fold in the cranberries.

Pour the mix into the prepared dish and bake for 30-35 minutes or until the top is golden brown. Enjoy!
