Canola Oil (Best Option)
1:1 (1 cup canola oil per 1 cup vegetable oil)Canola oil is very similar to vegetable oil in terms of fat content and neutral flavor profile, making it an excellent direct substitute. Both oils are primarily composed of unsaturated fats that contribute to a tender crumb and moist texture in cakes.
When substituting, use the same volume as vegetable oil. Ensure the canola oil is fresh to avoid any off-flavors. Because it is liquid at room temperature, it integrates smoothly into the batter.
The final cake will have nearly identical texture and flavor, maintaining the moistness and light crumb expected from vegetable oil-based recipes.
