Preheat the oven to 375F and line a muffin tin.

Whisk the flour, sugar, and baking powder in a large bowl.

Combine the milk, oil, eggs, and orange zest in another bowl.

Fold the wet into the dry until just mixed, then fold in the cranberries.

Divide among the cups and bake 18 to 20 minutes until lightly golden.

Cool 5 minutes before serving.
