Garlic Powder (Best Option)
1/4 teaspoon per 1 clove garlicGarlic powder is dehydrated garlic that retains the essential flavor compounds responsible for garlic's characteristic taste. Because it is dry, it does not alter the moisture content of muffin batter, which is critical for proper rise and crumb structure.
When substituting, use a precise ratio to avoid overpowering the batter. Mix it evenly with dry ingredients to ensure uniform flavor distribution. Avoid adding extra liquids when using garlic powder.
Compared to fresh garlic, garlic powder offers a subtler, more evenly dispersed garlic flavor that complements the muffin without causing textural issues or uneven baking.
