Melted Coconut Oil (Best Option)
1:1 (1 cup melted coconut oil per 1 cup vegetable oil)Coconut oil is high in saturated fats, similar to vegetable oil, which helps maintain the tender crumb and moist texture essential in banana bread. Its melting point allows it to blend well with batter, mimicking the mouthfeel of vegetable oil.
To ensure even distribution, melt coconut oil just until liquid and cool slightly before mixing into the batter. Avoid using refined coconut oil if you want a neutral flavor; virgin coconut oil adds a mild coconut note.
The final banana bread will be moist with a tender crumb, very close to the original texture and mouthfeel, with only a subtle coconut flavor if virgin coconut oil is used.
