5 Best Buttermilk Substitutes for Waffles

Quick tip: This mixture closely mimics buttermilk’s acidity and consistency, ensuring proper rise and tender texture.

Adding an acid like lemon juice or vinegar to milk creates a homemade buttermilk substitute by curdling the milk slightly and increasing acidity. This acidity is crucial for activating baking soda in the waffle batter, which produces carbon dioxide and helps the waffles rise and become fluffy.

For best results, use whole or 2% milk and allow the acid and milk mixture to sit for about 5 minutes before incorporating it into the batter. This ensures the milk thickens slightly and the acidity is balanced.

Compared to real buttermilk, this substitute produces very similar texture and flavor in waffles, maintaining the characteristic tenderness and slight tang without altering batter viscosity significantly.

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.

Quick tip: Cream of tartar provides acidity without altering liquid volume, helping maintain batter consistency.

Cream of tartar is an acidic powder that can replicate the acid component of buttermilk when combined with milk. This acidity activates baking soda in the waffle batter, promoting rise and tenderness.

Mix cream of tartar into the milk thoroughly before adding to the batter. This method is convenient when lemon juice or vinegar is unavailable.

Waffles made with this substitute have a similar rise and lightness to those made with buttermilk, though the flavor lacks the subtle tang of fermented dairy.

Quick tip: Using sour milk immediately provides acidity but less thickening than traditional buttermilk substitutes.

Sour milk is created by adding vinegar to milk but using it immediately without letting it curdle fully. It provides acidity to activate baking soda but lacks the slight thickening and flavor development of proper buttermilk.

This substitute is a quick fix but may result in slightly less tender waffles due to reduced acidity and minimal curdling.

The final waffles will be acceptable but may have a less pronounced tang and slightly different texture compared to those made with real buttermilk.

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.
