โญ Vegetable Oil (Best Gluten-Free Option)
3/4 cup vegetable oil per 1 cup butterVegetable oil is 100% fat and liquid at room temperature, which means it adds moisture but lacks the ability to aerate the batter like solid fats do. This results in a denser crumb and less rise in carrot cake.
To compensate, reduce the oil slightly and ensure proper mixing to incorporate air. Adding a small amount of baking powder or baking soda can help with leavening.
The cake will be moist but less structured and may feel heavier than the butter-based original.
