Canola Oil (Best Option)
1:1Canola oil is chemically similar to vegetable oil, primarily composed of unsaturated fats that contribute to moist, tender baked goods. Its neutral flavor profile ensures it doesn't interfere with the muffin's intended taste.
When substituting, use the exact same volume as vegetable oil. Ensure the oil is fresh to avoid any off-flavors. Canola oil's high smoke point also makes it stable during baking.
The final muffins will have a texture and crumb very close to those made with vegetable oil, with no noticeable difference in flavor or moisture.
