Recipe Substitutions: What to Use When You're Missing an Ingredient

You're halfway through a recipe and you discover you're out of buttermilk. Or heavy cream. Or the one egg you needed. Substitutions are one of the most practical cooking skills — knowing what swaps work means fewer emergency grocery runs and less food going to waste.

Here are the substitutions that actually work, sorted by what you've run out of.

Dairy substitutions

Buttermilk (1 cup)

• 1 cup milk + 1 tablespoon white vinegar or lemon juice: stir and let sit 5 minutes. This is the most reliable substitute and works in pancakes, biscuits, cakes, and marinades.
• 1 cup plain yogurt: thinned slightly with milk if needed. Works in baking and marinades.
• 1 cup kefir: works 1:1.

Heavy cream (1 cup)

• 3/4 cup milk + 1/4 cup melted butter: works in sauces and baking (not whippable)
• Full-fat coconut cream: works 1:1 in soups, curries, and desserts. Adds coconut flavor.
• Evaporated milk: works 1:1 in baking (not whippable)

Sour cream (1 cup)

• 1 cup plain Greek yogurt: works 1:1 in almost every application
• 1 cup crème fraîche: slightly richer, works exactly the same
• 3/4 cup cream cheese + 3 tablespoons milk, blended smooth: works in dips and sauces

Milk (1 cup)

• Any plant milk (oat, almond, soy): works 1:1 in most baking and cooking
• Half-and-half diluted 50/50 with water: richer than milk but works
• Evaporated milk + equal amount water: works well

Cream cheese (1 cup)

• Mascarpone: closest substitute, slightly less tangy
• Ricotta, drained and blended until smooth: works in dips, baked goods; slightly grainy texture
• Greek yogurt cream cheese: works 1:1 in most uses

Egg substitutions

1 whole egg (for binding in baking)

• 1 tablespoon ground flaxseed + 3 tablespoons water: mix and let sit 5 minutes until gel forms. Works well in cookies, muffins, quick breads.
• 1 tablespoon chia seeds + 3 tablespoons water: same method. Works the same.
• 3 tablespoons aquafaba (liquid from a can of chickpeas): works best in meringues and light baked goods
• 1/4 cup unsweetened applesauce: adds moisture, works in muffins and cakes. Slightly denser result.
• 1/4 cup mashed banana: works in pancakes, muffins, banana-adjacent baked goods. Adds banana flavor.

Egg wash (for glazing pastry)

• Whole milk or cream: brushed on, gives a similar golden color
• Melted butter: slightly different look but works
• Plant milk: lighter color, still works for most purposes

Flour substitutions

All-purpose flour (1 cup)

• 1 cup + 2 tablespoons cake flour: lighter texture
• 1 cup whole wheat flour: denser, nuttier; works in rustic baked goods
• 7/8 cup (14 tablespoons) bread flour: protein content is higher; adds chew
• For gluten-free: 1 cup 1-to-1 gluten-free flour blend (Bob's Red Mill, King Arthur). Works in most recipes

Bread flour (1 cup)

• 1 cup all-purpose flour: works in most recipes; slightly less chewy result

Self-rising flour (1 cup)

• 1 cup all-purpose flour + 1.5 teaspoons baking powder + 1/4 teaspoon salt: works exactly the same

Cake flour (1 cup)

• 3/4 cup + 2 tablespoons all-purpose flour + 2 tablespoons cornstarch: sifted together

Leavening substitutions

Baking powder (1 teaspoon)

• 1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar: use immediately, doesn't hold

Baking soda (1 teaspoon)

• 3 teaspoons baking powder: but this adds sodium, so reduce other salt in recipe

Fat substitutions

Butter (1 cup / 2 sticks, for baking)

• 1 cup coconut oil (solid, not melted): works well in cookies and quick breads. Slight coconut flavor.
• 7/8 cup vegetable oil: use 7/8 cup (not a full cup) since oil is 100% fat, butter is ~80%
• 1 cup unsweetened applesauce: reduces fat significantly; more dense, moist result

Oil (1 cup, for baking)

• 1 cup melted butter: richer flavor, works well
• 1 cup applesauce: reduces fat, adds moisture; texture will be slightly denser

Sweetener substitutions

Granulated sugar (1 cup)

• 1 cup brown sugar: adds molasses flavor, keeps baked goods more moist
• 3/4 cup honey: reduce other liquids in recipe by 3 tablespoons, lower oven temp by 25°F, use immediately
• 3/4 cup maple syrup: similar adjustments as honey
• 1 cup coconut sugar: works 1:1, slightly darker flavor

Brown sugar (1 cup)

• 1 cup granulated sugar + 1 tablespoon molasses: mix thoroughly

Honey (1 cup)

• 1 cup maple syrup: works 1:1 in most recipes
• 1 cup agave nectar: similar sweetness profile

Powdered sugar (1 cup)

• 1 cup granulated sugar + 1 tablespoon cornstarch, blended until fine: use a blender, not a food processor

Acid and flavor substitutions

Lemon juice (1 tablespoon)

• 1 tablespoon lime juice: nearly identical in most cooking contexts
• 1/2 tablespoon white wine vinegar: for cooked applications
• 1/2 teaspoon citric acid dissolved in 2 tablespoons water

Red wine (1 cup, for cooking)

• 1 cup beef broth + 1 tablespoon red wine vinegar: works in braises and stews
• 1 cup pomegranate juice: similar tannin profile, works in red meat dishes
• 1 cup grape juice + 1 tablespoon red wine vinegar

White wine (1 cup, for cooking)

• 1 cup chicken broth + 1 tablespoon white wine vinegar: works in sauces and braises
• 1 cup apple juice or white grape juice + 1 tablespoon vinegar

Soy sauce (1 tablespoon)

• 1 tablespoon coconut aminos: similar flavor, less sodium, slightly sweeter
• 1 tablespoon tamari: gluten-free, nearly identical flavor
• 1 tablespoon Worcestershire sauce: different flavor profile but adds umami

Fresh herbs (1 tablespoon fresh)

• 1 teaspoon dried herbs: dried is more concentrated; use 1/3 the amount

When substitutions don't work

Some recipes are not forgiving of substitutions:

Precise baking chemistry: Delicate layer cakes, soufflés, macarons — these depend on exact ratios. Substituting changes the chemistry in ways that are hard to predict.

Eggs as structure: In custards, cheesecakes, and quiches, eggs create the structure of the dish. Egg-free substitutions often don't hold up.

Fat in laminated dough: Croissants and puff pastry depend on butter's specific melting point and fat content. Substitutes produce a completely different texture.

For anything finicky: look up a recipe specifically designed around your substitute ingredient, rather than adapting an existing recipe.

Save these substitutions for later

Rather than trying to remember all of these, keep a substitution reference in your recipe app. When you're mid-cook and stuck, search "buttermilk substitution" in your notes.

RecipeClip lets you add custom notes and reference cards to your library. You can create a recipe called "Substitution Reference" and paste this list in — then search for it whenever you need it.

The buttermilk swap alone will save you a grocery run this month. Keep the list wherever you cook: mine lives in RecipeClip, one search away from the recipe it's rescuing. Start free.
