Light Olive Oil (Best Option)
1:1 (1 cup light olive oil per 1 cup avocado oil)Light olive oil has a similar fatty acid profile to avocado oil, primarily monounsaturated fats, which help retain moisture and create a tender crumb in banana bread. Its mild flavor ensures the banana remains the star of the flavor profile.
When substituting, use the same volume as avocado oil. Avoid extra virgin olive oil as its stronger flavor can dominate the bread. Ensure the oil is fresh to prevent off-flavors.
The final banana bread will be moist and tender with a subtle fruity undertone, closely matching the texture and flavor of the original recipe using avocado oil.
