Canola Oil (Best Option)
1:1 (1 cup canola oil per 1 cup olive oil)Canola oil is a neutral-flavored oil with a fatty acid profile similar to olive oil, providing the necessary fat to create a tender crumb and moist texture in brownies. Its mild taste ensures the chocolate flavor remains prominent without interference.
When substituting, use the same volume as olive oil. Ensure the oil is fresh to avoid any off-flavors. Because canola oil has a slightly higher smoke point, it is stable during baking.
The final brownies will have a texture and moisture level very close to those made with olive oil, but with a more neutral flavor profile that some may prefer.
