What Substitutes For Baking Powder

You’re halfway through your Sunday morning pancake ritual, or perhaps a last-minute banana bread craving, when you open the cabinet and—nothing. The little orange can of baking powder is staring back at you, empty. Don’t panic. The kitchen gods have not abandoned you. In fact, this tiny crisis is just an excuse to get a little creative, and your baking might just end up better for it.

The Science of a Little Lift

First, a quick look under the hood. Baking powder is a leavening agent, which is just a fancy way of saying it makes your cakes and muffins rise. It’s a pre-mixed combo of an acid (like cream of tartar) and a base (baking soda), plus a little starch to keep them from reacting in the can.

When you add liquid and heat, these two throw a tiny chemical party, releasing carbon dioxide bubbles. Those bubbles are what give your baked goods that light, fluffy texture you love. So, when you’re out, the goal is to recreate that same fizzy reaction with other pantry staples.

The best part? Most substitutes are already sitting in your fridge or spice rack. You just need to know which one fits the vibe of what you’re baking today.

Your Pantry’s Rising Stars

Let’s start with the MVP: Baking Soda + Acidic Ingredient. This is the most direct swap. For every one teaspoon of baking powder your recipe calls for, use ¼ teaspoon of baking soda plus ½ teaspoon of an acid like lemon juice, white vinegar, or buttermilk.

This duo works fast, so get your batter into the oven quickly. It’s perfect for tangy recipes like lemon cakes or sourdough biscuits, where that little zing actually enhances the flavor.

Fun fact: This is essentially how baking powder was invented in the 1840s. A Harvard chemist named Eben Norton Horsford got tired of home cooks having to mix their own acids and bases, so he combined them into one convenient product. Thanks, Eben.

Yogurt and Buttermilk: The Cool Kids

If you have plain yogurt or buttermilk in the fridge, you’re in luck. Both are naturally acidic and work beautifully with baking soda. For every cup of buttermilk or yogurt you use, add ½ teaspoon of baking soda to the dry ingredients.

How to Substitute Baking Powder and Baking Soda

This substitute is a game-changer for scones and pancakes. The yogurt adds moisture and a subtle tang that feels almost European—like something you’d get at a cozy café in Copenhagen. Just remember to reduce the other liquid in your recipe by the same amount you’re adding.

Pro tip: If the milk in your fridge has just gone a little sour, don’t throw it out—that’s homemade buttermilk. Our ancestors would be proud, and you’ll save a trip to the store.

Whipped Egg Whites: The Cloud Trick

For an airy, almost magical lift, turn to egg whites. Separate the whites from the yolks and whip them with a clean whisk until they form stiff, glossy peaks. Then, gently fold them into your batter at the very end.

This technique is a bit more hands-on, but the texture is divine. It’s how classic sponge cakes and angel food cakes get their ethereal height. Think of it as the soufflé shortcut—especially if you’re trying to impress someone without a lot of fancy ingredients.

A cultural nod: Japanese ‘hotcake’ recipes often use whipped egg whites for a puffy, jiggly result that’s somewhere between a pancake and a soufflé. Your Saturday breakfast just got a Tokyo upgrade.

The Club Soda Surprise

Here’s a lazy Sunday cheat code: Club soda or sparkling water. These fizzy liquids are already packed with carbon dioxide. Swap some (or all) of the regular liquid in your recipe for an equal amount of club soda.

This works best for thinner batters, like crepes, waffles, or tempura-style frying. The bubbles give you a light, crispy result without any chemical reaction at all. It’s not a perfect one-to-one swap for thick cakes, but for a quick weeknight dinner project? It’s genius.

Fun fact: In Queer Eye Antoni Porowski has been known to use sparkling water in his pancake batter for a “brunch that’s both chic and effortless.” If it’s good enough for the Fab Five, it’s good enough for you.

When to Just Skip It

Believe it or not, for some recipes, you can simply leave the baking powder out. Dense, flat baked goods like shortbread cookies, brownies, or tart crusts don’t need a lift. They’re meant to be low and rich.

This is a great moment to embrace the beautiful imperfection of homemade food. Not every cookie needs to puff up like a pillow. Sometimes, a flat, chewy chocolate chip cookie is exactly what the soul asks for.

baking powder substitute: What to Use When You Run Out

The key is knowing your baking goal: if you want height and fluff, use a substitute. If you want richness and density, embrace the flatness. That’s called intention, not failure.

Your Substitution Cheat Sheet

Keep this in your phone notes: For 1 teaspoon baking powder, use ¼ tsp baking soda + ½ tsp lemon juice or vinegar. Or use ¼ cup yogurt + ¼ tsp baking soda. Or simply whip two egg whites and fold them in.

And when all else fails? Use ½ cup of club soda for a quick bread or waffle batter. Every single one of these options has saved me from a dramatic kitchen meltdown at least twice. They work because you understand the chemistry now.

You’re not just substituting; you’re improvising with intention.

A Final Reflection

The next time you run out of a critical ingredient, take a breath. It’s rarely a disaster—it’s an invitation to adapt. Life, much like a recipe, doesn’t always have every ingredient on hand. Sometimes, the best versions of things come from what you already have, not what you think you need.

So go ahead, use that last spoonful of yogurt. Fold in those egg whites. Pop open that can of club soda. Your pancakes will still rise, your brownies will still comfort you, and you’ll walk away feeling a little bit more like a kitchen alchemist. That’s a win no store-bought can can match.
