Garlic-Infused Olive Oil (Best Option)
1 teaspoon per 1 cup of butterGarlic-infused olive oil works well because it delivers the garlic flavor in an oil form that integrates smoothly into the butter-based batter without adding water content, which could disrupt the pound cake’s structure. The infusion process mellows the garlic, preventing harshness.
For best results, use high-quality infused oil and avoid overheating it during mixing to preserve flavor. Adjust the quantity slightly if the oil has a strong garlic concentration.
Compared to fresh garlic, this substitute maintains the cake’s dense, tender crumb and sweet profile while introducing a nuanced savory note that complements rather than dominates.
