Several easy substitutes replicate buttermilk’s creamy texture and slight tartness, often using common kitchen staples.

Milk mixed with vinegar or lemon juice, yogurt, or kefir can provide the necessary acidity and moisture.

Each alternative brings subtle differences in taste and consistency that can be adjusted to suit recipes.

This guide offers ten buttermilk substitutes and even includes a simple homemade buttermilk recipe.

Understanding how to replace buttermilk keeps your baked goods tender and flavorful.

Use these options to avoid last-minute ingredient runs and maintain recipe success.

Why You’ll Need Buttermilk Substitutes

Sometimes you just don’t have buttermilk on hand, or it doesn’t fit your needs, so having a substitute ready can save the day. Here are some reasons why you might need buttermilk alternatives.

• Dietary Restrictions: Lactose sensitivity, dairy allergies, or a vegan lifestyle mean traditional buttermilk is off-limits.
• Flavor Control: You want the tang of buttermilk without the dairy taste, or you need a milder acidity for delicate batters.
• Health Preferences: Cutting back on calories or fat may lead you to choose a lighter, lower-fat alternative.

Must-Known Buttermilk Substitutes

Buttermilk substitutes add tangy flavor and tenderness to baked goods and dressings with dairy and non-dairy options. Multiple alternatives offer great results. Discover the must-know swaps for baking success.

Homemade Buttermilk Milk and Lemon Juice

Making buttermilk at home is surprisingly easy when you combine regular milk with a splash of lemon juice.

Most people don't have bacteria cultures sitting in their pantry, so this simple acid-milk reaction creates a perfect substitute that professional bakers rely on daily.

The process takes just minutes - add one tablespoon of lemon juice to a measuring cup, pour in milk until it reaches the one-cup mark, stir gently, and let it sit briefly while the mixture curdles.

This homemade version works beautifully in cakes, cookies, and sauces without requiring exact measurements - just under one cup of milk with a tablespoon of lemon juice replaces each cup of traditional buttermilk.

The quick substitution has become my go-to solution whenever recipes call for buttermilk.

Milk and White Vinegar

Substitution often makes cooking easier when you don't have exactly what a recipe calls for, especially with dairy products like buttermilk.

Milk combined with lemon juice creates a similar reaction to milk with white vinegar because both acids cause curdling that mimics commercial buttermilk.

The acids work differently though - lemon juice typically produces more tender baked goods while white vinegar creates a slightly firmer texture and can sometimes add an unwanted tang to delicate recipes.

Most home cooks appreciate knowing these simple swaps since fresh lemons aren't always available in the refrigerator when the baking urge strikes.

Regular white vinegar works best for this substitution since other varieties like apple cider or balsamic will add their distinctive flavors to your dish.

For perfect results, simply mix just under one cup of milk with one tablespoon of white vinegar to replace each cup of buttermilk in your recipe.

Kefir

Kefir stands out as the ideal replacement for buttermilk in recipes, offering similar thickness and fermented taste without requiring any mixing or preparation.

Many people don't realize this lesser-known cousin actually contains more gut-friendly probiotics and beneficial bacteria than regular buttermilk, especially valuable in cold preparations like dressings.

When shopping for kefir, unsweetened and unflavored varieties work best to maintain the authentic buttermilk flavor profile in your cooking.

The substitution couldn't be simpler - just use equal amounts of kefir in place of buttermilk in any recipe calling for it.

For baked goods and heated dishes, both ingredients perform nearly identically since the heating process reduces those extra beneficial microbes anyway.

Milk/Water and Yogurt

Plain yogurt is an excellent substitute for buttermilk in most recipes due to their similar properties as fermented milk products with comparable calcium, fat, and calorie content.

The main difference lies in yogurt's thicker consistency, which might not affect cakes but could be noticeable in dressings or slaws.

Thinning plain yogurt with milk creates an ideal 1:1 replacement – simply mix 3/4 cup yogurt with 1/4 cup milk, or use equal parts Greek yogurt and milk for the perfect consistency.

This quick substitution works perfectly in pancakes, biscuits, and other baked goods when you're out of buttermilk.

The subtle tangy flavor of yogurt even enhances many recipes, making it sometimes preferable to the original ingredient.

Buttermilk Powder

Buttermilk powder stands out as a brilliant money-saving alternative to fresh buttermilk, especially since the regular kind often spoils before you can use it all.

The powder delivers identical flavor while lasting much longer in your pantry, making it perfect for occasional baking projects.

Using it couldn't be simpler - just combine one tablespoon of powder with a quarter cup of water for each portion needed, or add the powder to your dry ingredients and water to your wet ingredients when baking.

Many people keep this versatile ingredient on hand for pancakes, biscuits, and marinades without worrying about waste or last-minute grocery runs.

The standard substitution ratio works out to a quarter cup of powder plus one cup of water to replace one cup of traditional buttermilk in any recipe.

Milk/Water and Sour Cream

Buttermilk substitutes offer handy alternatives when you're in the middle of baking and realize your fridge is missing this key ingredient.

Sour cream mixed with water or milk creates a tangier flavor profile than traditional buttermilk, though its higher fat content typically results in denser baked goods.

The chemistry behind buttermilk's magic comes from its acidity reacting with baking soda to create air pockets that make cakes and breads delightfully fluffy.

For best results, simply whisk three-quarters cup of sour cream with a quarter cup of milk or water until smooth before adding to your recipe.

This substitute works especially well in savory applications like creamy salad dressings and coleslaws where the extra richness actually enhances the final dish.

Soy/Almond Milk and Lemon Juice/Vinegar

Buttermilk substitutions offer simple solutions when this key ingredient isn't in your refrigerator.

Many people rely on the classic combination of regular milk with a tablespoon of lemon juice or vinegar as the most effective replacement, allowing it to sit for 5-10 minutes until slightly curdled.

For those needing dairy-free options, unsweetened soy or almond milk works wonderfully with the same acid addition method, though the flavor profile might differ slightly from traditional buttermilk.

Yogurt thinned with a bit of milk creates another excellent alternative that maintains the tanginess buttermilk brings to recipes.

The substitution ratios remain straightforward – one cup of buttermilk equals one cup of your chosen alternative mixture.

Coconut milk should be avoided in these substitutions as its distinctive flavor and composition won't produce the desired results in most recipes.

Cashew Milk and Vinegar

Substituting buttermilk with cashew milk offers a dairy-free alternative, though it comes with an important distinction from other plant-based options.

Unlike soy or almond milk, cashew milk doesn't react well with lemon juice, failing to achieve that characteristic buttermilk texture many recipes require.

The solution lies in using vinegar instead, which perfectly creates the right consistency when mixed with unsweetened cashew milk.

For best results, combine just under one cup of cashew milk with one tablespoon of vinegar, allowing the mixture to sit briefly before adding it to your recipe.

This simple swap maintains a one-to-one ratio with traditional buttermilk, making it easy to adjust your favorite recipes without complicated calculations.

Cashew milk's mild flavor also makes it an excellent buttermilk substitute in both sweet and savory dishes where you want the acidity without overpowering other ingredients.

Tofu, Water, and Vinegar

Substitution offers a seamless way to replace buttermilk when you're in a pinch, with tofu mixture being one of the most effective vegan alternatives for baking projects.

Making this substitute requires silken tofu (not regular or firm), a pinch of salt, water, and a tablespoon of lemon juice or vinegar blended until smooth and left to rest for 10 minutes.

The results in baked goods are remarkable, producing textures and flavors that closely mimic traditional buttermilk without any animal products.

For optimal results, simply use 1/4 cup of tofu with the proper amounts of salt, water, and acid to replace each cup of buttermilk in your recipe.

This method may require slightly more effort than other substitutions, but the superior outcome in cakes, muffins, and quick breads makes the extra minute or two completely worthwhile.

Applesauce

Substituting buttermilk with applesauce offers the simplest solution for home bakers looking to make delicious treats without dairy.

This straightforward swap requires no additional mixing or preparation- just replace buttermilk with plain applesauce in a perfect one-to-one ratio.

For best results, choose unsweetened applesauce and avoid flavored varieties that might alter your recipe's intended taste.

The applesauce works magic in baked goods by creating the same light, moist texture that buttermilk provides, though it won't work for sauces, marinades, or dressings.

Many bakers actually prefer this substitution because it adds a subtle fruity undertone that complements cakes, muffins, and quick breads wonderfully.

Buttermilk Uses in Recipes

Buttermilk’s tangy richness makes it a superstar in both sweet and savory dishes. From light, fluffy pancakes to creamy dressings and tenderizing marinades, here’s a quick look at how buttermilk can elevate your favorite recipes.

• Pancakes & Waffles: Adds tang and tenderizes the batter, giving light, fluffy pancakes and crisp-edged waffles.
• Biscuits & Scones: Reacts with baking soda to create lift and flaky layers, while its acidity adds a subtle tang.
• Marinades & Brines: Tenderizes meat by breaking down proteins and infuses a mild, creamy flavor, perfect for fried chicken or pork.
• Cakes & Quick Breads: Keeps crumb moist and soft, while its acidity enhances leavening for a lighter texture in banana bread or spice cakes.
• Dressings & Dips: Creates creamy, tangy dressings and dips that cling nicely to salads, veggies, and chips without oil separation.

How to Pick Buttermilk Substitutes Based on Flavor and Consistency

When choosing a stand-in for buttermilk, two things matter most: how tangy it is and how thick it feels. Here’s what you should look for:

Tanginess and Acidity

Buttermilk’s signature tang comes from its mild lactic acidity. You’ll want a substitute that brings a similar bright bite, enough acid to react with leaveners and give that tender crumb, but not so sharp that it tastes sour.

Look for a mixture that sits between a gentle yogurt-like tang and a light citrus zing. If it’s too flat, you may miss the lift in pancakes and cakes; if it’s too tart, your batter can curdle or take on an unpleasant bite.

Creaminess and Thickness

The body of buttermilk is thicker than plain milk but pourable enough to flow into batters. Your substitute should coat the back of a spoon, thick enough to add richness, yet still easily stir into dry ingredients.

Too thin a liquid will yield a runny batter and dry bake; too thick a base can weigh things down and inhibit rise. Aim for that perfect “coat” consistency so your final results stay moist and tender.

Fat Content and Mouthfeel

Even low-fat versions of buttermilk have a bit of richness that smooths out texture and carries flavor. When picking an alternative, consider whether it feels almost buttery or noticeably light on the tongue.

A slightly richer option will add silkiness to custards and biscuits, while a leaner choice keeps batters airy. Balance your needs: richer for indulgent bakes, lighter for crispier pancakes or scones.

How to Make Buttermilk Substitutes at Home

Making a buttermilk substitute at home couldn’t be simpler; you only need an acidic ingredient and a creamy base. Here are three easy methods:

Milk Plus Acid

1. Measure out 1 cup of regular milk (dairy or unsweetened plant milk).

2. Stir in 1 tablespoon of a mild acid (fresh lemon juice or white vinegar).

3. Let the mixture sit for 5–10 minutes until it thickens and curdles slightly.

4. Give it a gentle stir before using.

Yogurt Dilution

1. Spoon ¾ cup of plain yogurt into a bowl.

2. Add ¼ cup of water or milk and whisk until smooth.

3. Use this in any recipe that calls for 1 cup of buttermilk.

Spoonable Cultured Dairy (or Non-Dairy)

1. Scoop 1 cup of cultured dairy like kefir or a thick, drinkable yogurt alternative.

2. If it’s very thick, stir in a bit of water until it matches the consistency of buttermilk.

3. It’s ready to pour straight into your batter or dough.
