How much vegetable oil is needed for two batches of cookies?

The amount of vegetable oil needed for two batches of cookies depends on the specific recipe used. Typically, a single batch might require about 1/2 to 1 cup of oil, so for two batches, you would need approximately 1 to 2 cups. Always check the recipe for exact measurements, as some cookies may use butter or other fats instead of oil. Adjust based on your desired texture and flavor.
