Detailed Guide: Gluten-Free Buttermilk Substitutes in Waffles

⭐ Plain Yogurt (Thinned with Water) (Best Gluten-Free Option)

3/4 cup plain yogurt + 1/4 cup water per 1 cup buttermilk

Quick tip: Thinning yogurt adjusts its thickness to better mimic buttermilk, preserving acidity and moisture balance.

Plain yogurt contains lactic acid similar to buttermilk, which helps activate baking soda for leavening. However, yogurt is thicker, so diluting it with water restores the proper batter consistency, preventing overly dense waffles.

Use plain, unsweetened yogurt and mix thoroughly with water before adding to the batter. Avoid flavored or Greek yogurt as they can affect taste and texture.

This substitute yields waffles with a slightly tangier flavor and a moist, tender crumb, though the texture may be marginally denser than with true buttermilk.

Coconut Milk + Lemon Juice

1 cup full-fat coconut milk + 1 tablespoon lemon juice (let sit 5 minutes)

Quick tip: A dairy-free alternative that adds acidity and richness but imparts a mild coconut flavor.

Full-fat coconut milk combined with lemon juice creates an acidic, creamy liquid that can substitute buttermilk in waffles, especially for dairy-free diets. The acidity activates baking soda, while the fat content helps maintain tenderness.

Allow the mixture to sit for 5 minutes to thicken slightly and develop acidity. Be aware that coconut milk’s distinct flavor can subtly influence the waffle’s taste.

Waffles made with this substitute are tender and moist but will have a mild coconut undertone, which may or may not be desirable depending on preference.
