Step 1

Preheat the oven to 400 degrees Fahrenheit. Line the muffin tin with liners or grease it with baking spray or butter.

Step 2

Sift together the flour, sugar, baking powder, and salt. In a 1-cup measuring cup, pour the vegetable oil, egg, and enough milk to fill the cup. Whisk it in a bowl until well-combined.

Step 3

Pour the oil mixture into the flour mixture and whisk just until you no longer see streaks of flour. Gently mix in the orange zest, orange juice, and cranberries.

Step 4

Fill the muffin cups 3/4 full with batter. Bake for 15 to 20 minutes, or until a toothpick inserted into the center comes out clean. The tops should spring back when pressed.

Step 5

Let the muffins cool in the pan for 5 minutes. Remove them from pan and let them cool completely on a wire rack. Serve and enjoy.
