What is Baking Powder?

Before we dive into substitutes, let’s quickly understand what baking powder actually is and why it works.

Baking powder is a leavening agent that makes baked goods rise and become fluffy. It’s actually a mixture of three things:

• Baking soda (sodium bicarbonate) – the base that does the actual rising
• Acid (usually cream of tartar) – reacts with the baking soda to create carbon dioxide bubbles
• Cornstarch – keeps the mixture dry and prevents premature reaction

When baking powder gets wet, the acid and base react to create carbon dioxide gas bubbles. These bubbles get trapped in your batter, causing it to rise and creating that light, fluffy texture we love in pancakes, cakes, and biscuits.

Single-Acting vs. Double-Acting Baking Powder

Most store-bought baking powder is “double-acting,” meaning it reacts twice:

• First reaction: When it gets wet (mixing the batter)
• Second reaction: When it gets hot (in the oven)

This gives you a bigger window to work with—you don’t have to rush your batter into the oven immediately.

Important for substitutes: Most homemade substitutes are “single-acting,” meaning they only react once when wet. You’ll need to work a bit faster and get your batter into the oven or onto the griddle quickly.

Best Baking Powder Substitute: Baking Soda + Cream of Tartar

Ratio: 1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar = 1 teaspoon baking powder

This is hands-down the best substitute because it’s essentially homemade baking powder. You’re mixing the exact ingredients that are in store-bought baking powder (minus the cornstarch, which isn’t necessary).

Why This Works Best

• Makes the same chemical reaction as commercial baking powder
• Works in ANY recipe that calls for baking powder
• Doesn’t change the flavor or texture of your baked goods
• Doesn’t require adjusting other ingredients

How to Use It

1. For every 1 teaspoon of baking powder your recipe calls for, mix 1/4 teaspoon baking soda with 1/2 teaspoon cream of tartar
2. Whisk them together first, then add to your dry ingredients
3. Proceed with your recipe as written
4. Bake immediately after mixing—this substitute is single-acting

Example Conversions

• 1 teaspoon baking powder = 1/4 tsp baking soda + 1/2 tsp cream of tartar
• 2 teaspoons baking powder = 1/2 tsp baking soda + 1 tsp cream of tartar
• 1 tablespoon baking powder = 3/4 tsp baking soda + 1 1/2 tsp cream of tartar

Pro tip: Make a big batch! Mix 1 tablespoon baking soda + 2 tablespoons cream of tartar and store in an airtight container. This equals 1/4 cup of baking powder and will last for several months.

Baking Soda + Buttermilk Substitute

Ratio: 1/4 teaspoon baking soda + 1/2 cup buttermilk (replace 1/2 cup of the liquid in your recipe)

Buttermilk is naturally acidic, so it reacts with baking soda to create the carbon dioxide bubbles you need for rising.

Why This Works

• Buttermilk provides the acid needed to activate baking soda
• Adds extra moisture and tanginess to baked goods
• Creates a tender, fluffy texture
• Especially good for pancakes, biscuits, and cakes

How to Use It

1. For every 1 teaspoon of baking powder, use 1/4 teaspoon baking soda
2. Replace 1/2 cup of the liquid in your recipe with 1/2 cup buttermilk
3. Mix the baking soda with your dry ingredients
4. Add the buttermilk with your wet ingredients
5. Bake immediately—the reaction starts as soon as wet and dry ingredients mix

Baking Soda + Plain Yogurt Substitute

Ratio: 1/4 teaspoon baking soda + 1/2 cup plain yogurt (replace 1/2 cup liquid in recipe)

Plain yogurt is acidic like buttermilk, making it another excellent option for activating baking soda.

Why This Works

• Yogurt’s acidity activates the baking soda
• Adds moisture and makes a tender crumb
• Slightly tangy flavor (use Greek yogurt for thicker batter)
• Great for muffins, quick breads, and cakes

How to Use It

1. For every 1 teaspoon of baking powder, use 1/4 teaspoon baking soda
2. Replace 1/2 cup of liquid with 1/2 cup plain yogurt
3. If using Greek yogurt, you may need to thin it with a tablespoon or two of milk
4. Mix and bake immediately

Tip: Avoid flavored or sweetened yogurt—use plain, unsweetened yogurt only.

Baking Soda + Vinegar Substitute

Ratio: 1/4 teaspoon baking soda + 1/2 teaspoon white vinegar or apple cider vinegar

Remember the volcano experiment from elementary school? That’s baking soda + vinegar! This classic chemical reaction works for baking too.

Why This Works

• Vinegar’s acid reacts immediately with baking soda
• Makes lots of carbon dioxide bubbles quickly
• No flavor impact (vinegar taste bakes out)
• Works when you don’t have cream of tartar or buttermilk

How to Use It

1. For every 1 teaspoon of baking powder, mix 1/4 teaspoon baking soda with 1/2 teaspoon vinegar
2. Add the baking soda to your dry ingredients
3. Add the vinegar to your wet ingredients
4. Mix wet and dry quickly and bake IMMEDIATELY—the reaction happens fast!

Baking Soda + Lemon Juice Substitute

Ratio: 1/4 teaspoon baking soda + 1/2 teaspoon fresh lemon juice

Lemon juice works just like vinegar—it’s acidic enough to activate baking soda.

Why This Works

• Lemon juice provides the acid for the reaction
• Adds a subtle citrus flavor (nice in light cakes or muffins)
• Reacts quickly like vinegar

How to Use It

1. Same method as vinegar substitute
2. Add baking soda to dry ingredients, lemon juice to wet
3. Mix and bake immediately

Best for: Light-colored baked goods where you don’t mind a hint of lemon flavor. Avoid using in chocolate or strongly flavored batters.

Self-Rising Flour Substitute

Ratio: Replace all-purpose flour with self-rising flour (1:1) and omit baking powder AND salt from recipe

Self-rising flour already has baking powder and salt mixed in, so you can skip adding them separately.

What is Self-Rising Flour?

Self-rising flour = all-purpose flour + baking powder + salt already mixed together

Typical ratio: 1 cup all-purpose flour + 1 1/2 teaspoons baking powder + 1/4 teaspoon salt

How to Use It

1. Replace all-purpose flour in your recipe with equal amount of self-rising flour
2. Omit the baking powder the recipe calls for
3. Omit or reduce the salt (self-rising flour already has salt)
4. Proceed with recipe as normal

Don’t have self-rising flour either? Make your own! For every 1 cup all-purpose flour, add 1 1/2 teaspoons baking powder and 1/4 teaspoon salt.

Club Soda Substitute

Ratio: Replace the liquid in your recipe with an equal amount of club soda

Club soda contains dissolved carbon dioxide, which provides some lift to baked goods.

Why This Works (Sort Of)

• The carbonation adds air bubbles to the batter
• Makes a lighter texture
• No chemical reaction needed

How to Use It

1. Replace milk, water, or other liquid in your recipe with club soda
2. Use the exact same amount (1:1 replacement)
3. Mix gently—you want to preserve the bubbles
4. Cook immediately before carbonation dissipates

The Catch

Club soda provides less lift than chemical leaveners. This works okay for:

• Pancakes (creates fluffier texture)
• Waffles (extra crispy exterior)
• Tempura batter (light and crispy coating)

But it’s NOT a good substitute for cakes, muffins, or biscuits that need significant rise.

Think of it as: A helper for texture, not a true baking powder replacement.

How to Choose the Right Substitute

• If You Have Cream of Tartar: Use baking soda + cream of tartar – This is your best bet. It works for everything and doesn’t require any recipe adjustments.
• If You’re Making Pancakes, Waffles, or Biscuits: Use baking soda + buttermilk (or yogurt) – The tangy flavor is perfect for these recipes, and you probably have milk to make buttermilk.
• If You’re Making Quick Bread or Muffins: Use baking soda + yogurt – Makes a moist, tender crumb. Greek yogurt works especially well.
• If You’re in a Rush: Use baking soda + vinegar (or lemon juice) – Fastest option using common ingredients. Just work quickly!
• If You Have Self-Rising Flour: Use self-rising flour – Simple swap for basic recipes like biscuits and pancakes.

Recipe-Specific Substitution Tips

For Pancakes

Best substitute: Baking soda + buttermilk

The tangy flavor is perfect for pancakes, and the extra moisture makes them fluffy. Replace 1/2 cup of your milk with 1/2 cup buttermilk and add 1/4 teaspoon baking soda per teaspoon of baking powder.

For Biscuits

Best substitute: Baking soda + cream of tartar OR self-rising flour

Biscuits need a neutral flavor, so cream of tartar is ideal. Self-rising flour also works great since biscuits are simple recipes.

For Cakes

Best substitute: Baking soda + cream of tartar

Cakes need precise leavening. Stick with cream of tartar so you don’t have to adjust liquid ratios and risk changing the texture.

For Muffins

Best substitute: Baking soda + yogurt

Yogurt adds moisture and creates a tender crumb—perfect for muffins. Use 1/4 teaspoon baking soda and replace 1/2 cup liquid with plain yogurt.

For Cookies

Best substitute: Baking soda + cream of tartar

Cookies need precise ratios for the right texture. Cream of tartar won’t mess with your recipe’s balance.

For Quick Breads (Banana Bread, Zucchini Bread)

Best substitute: Baking soda + buttermilk OR baking soda + yogurt

The extra moisture from buttermilk or yogurt keeps quick breads from getting dry.

Can You Make Baking Powder Ahead of Time?

Yes! If you have baking soda and cream of tartar, you can make a big batch of homemade baking powder to keep on hand.

Homemade Baking Powder Recipe

Ingredients:

• 2 tablespoons cream of tartar
• 1 tablespoon baking soda
• 1 tablespoon cornstarch (optional, helps prevent clumping)

Instructions:

1. Whisk all ingredients together until well combined
2. Store in an airtight container in a cool, dry place
3. Use exactly like store-bought baking powder (1:1 ratio)

Yield: About 1/4 cup (equals 12 teaspoons of baking powder)

Shelf life: 3-6 months. Test periodically by dropping 1/2 teaspoon into hot water—it should fizz vigorously.

How to Test if Your Baking Powder is Still Good

Before you go making substitutes, make sure your baking powder is actually dead:

The Hot Water Test:

1. Add 1 teaspoon baking powder to 1/3 cup hot water
2. It should fizz and bubble immediately and vigorously
3. Weak or no fizzing = time to replace (or make a substitute!)

Shelf life: Unopened baking powder lasts 12-18 months. Once opened, use within 6 months for best results.
