Detailed Guide: Each Buttermilk Substitute in Bread Pudding

Milk + Lemon Juice (Best Option)

1 cup milk + 1 tablespoon lemon juice (let sit 5 minutes)

Gluten-Free Nut-Free

Quick tip: Provides similar acidity and moisture as buttermilk, preserving texture and flavor.

This substitute works because the acid in lemon juice curdles the milk slightly, mimicking the tangy acidity of buttermilk which tenderizes the bread and balances sweetness in the custard. The acidity also helps activate baking soda if used, improving rise and texture.

For best results, use whole or 2% milk and let the mixture sit for at least 5 minutes to properly acidify. Stir before adding to the recipe.

Compared to buttermilk, this substitute yields a very similar custard texture and flavor, making it the closest match for bread pudding applications.

Milk + White Vinegar

1 cup milk + 1 tablespoon white vinegar (let sit 5 minutes)

Gluten-Free Nut-Free

Quick tip: Similar to lemon juice method, slightly sharper acidity but effective.

White vinegar acidifies the milk, causing slight curdling that replicates buttermilk’s acidity and tang. This acidity helps break down starches in the bread, ensuring a tender custard and balanced flavor.

Allow the mixture to sit for 5 minutes before use to ensure proper acidification. Use whole or 2% milk for best texture.

The flavor is slightly less fruity than lemon juice but still maintains the custard’s softness and moisture effectively.

Plain Yogurt (thinned with water or milk)

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

Gluten-Free Nut-Free

Quick tip: Thinned yogurt provides acidity and creaminess but can slightly thicken the custard.

Yogurt contains lactic acid similar to buttermilk, which tenderizes the bread and adds tang. Thinning it with water or milk adjusts the consistency closer to buttermilk, preventing overly dense custard.

Ensure the yogurt is plain and unsweetened. Mix thoroughly to avoid lumps and maintain smooth custard texture.

The final bread pudding may be slightly richer and creamier, with a mild tang, but overall remains close to the original.

Kefir

1 cup kefir per 1 cup buttermilk

Gluten-Free Nut-Free

Quick tip: Naturally tangy and thinner than yogurt, kefir closely mimics buttermilk’s acidity and texture.

Kefir is a fermented milk product with lactic acid bacteria, providing acidity and a thin consistency similar to buttermilk. This acidity helps tenderize the bread and balance sweetness in the custard.

Use plain, unsweetened kefir for best results. Its natural effervescence can add a slight lightness to the custard.

The bread pudding will have a subtle tang and moist texture very close to that made with buttermilk.

Coconut Milk + Lemon Juice

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

Vegan Gluten-Free Dairy-Free Nut-Free

Quick tip: Dairy-free option with acidity, but imparts a coconut flavor and slightly different texture.

Coconut milk provides fat and moisture, while lemon juice adds acidity to mimic buttermilk’s tenderizing effect. The acid curdles the coconut milk slightly, creating a tangy base for the custard.

Let the mixture sit for 5 minutes to allow acidification. Use full-fat coconut milk for richness.

This substitute changes the flavor profile, adding a mild coconut taste and slightly different mouthfeel, but maintains the custard’s moisture and tenderness.

❌ What NOT to Use as a Buttermilk Substitute in Bread Pudding

Plain Milk

Plain milk lacks the acidity that buttermilk provides, which is crucial for breaking down starches in the bread and achieving the desired tender, custardy texture in bread pudding. Using plain milk results in a denser, less flavorful dish.

Yogurt (without thinning)

Thick yogurt without dilution is too dense and can create an overly heavy texture in bread pudding, disrupting the custard’s smoothness and potentially causing uneven baking.

Sour Cream

Sour cream is much thicker and richer than buttermilk, which can cause the bread pudding to be overly dense and heavy, losing the light custardy quality typical of the dish.
