Vanilla Extract (Best Option)
1 teaspoon per 1/2 teaspoon almond extractVanilla extract works well as a substitute because it shares a similar sweet and aromatic profile that complements banana bread. The alcohol base helps disperse flavor evenly throughout the batter, similar to almond extract.
For best results, use pure vanilla extract rather than imitation, as it has a richer flavor. Be mindful not to increase the amount excessively to avoid overshadowing the banana.
The final bread will have a slightly different but still harmonious flavor, leaning more toward classic banana bread notes rather than the subtle nutty undertones almond extract provides.
