Understanding Gluten-Free Leavening Agents: Yeast, Baking Powder, and Baking Soda

Gluten-Free Leavening Agents

Leavening agents are the powerhouse behind every soft, airy, and well-risen bake. In gluten-free baking, understanding how these ingredients work becomes even more important because there’s no gluten network to trap gas or provide natural lift. Whether you’re making Japanese milk bread, Korean pancakes, Chinese steamed buns, or delicate Asian pastries, choosing the right leavening agent can make the difference between a dense result and a beautifully risen treat.

This guide breaks down the three essential leavening agents used in gluten-free baking—yeast, baking powder, and baking soda—and explains how and when to use each one for the best results.

Why Leavening Agents Matter More in Gluten-Free Baking

Gluten in wheat flour naturally captures gas and improves elasticity, allowing dough to stretch and rise. In gluten-free baking, this structure must be replaced with starches, gels, and binders. Leavening agents supply the lift, but the dough must be properly formulated to support it.

Knowing how each leavening agent behaves helps you choose the right one for the texture you're aiming for.

Yeast: For Flavor, Structure, and Slow Rise

Yeast is a living organism that feeds on sugar and produces carbon dioxide, which creates airy pockets throughout dough. It’s the classic choice for breads and buns, and it works extremely well in gluten-free versions of:

• Japanese milk bread
• Chinese steamed buns (baozi)
• Gluten-free brioche-style loaves
• Sweet rolls and enriched doughs

How Yeast Works in Gluten-Free Baking

Since yeast produces gas slowly, it gives dough time to hydrate fully and build structure through starch gelatinization and binders like xanthan gum or psyllium husk. This results in a tender crumb and deep, fermented flavor that chemical leaveners can’t replicate.

When to Use Yeast

Use yeast when your recipe needs:

• Chewiness
• Soft and stretchy texture
• Height and open crumb
• Fermented flavor

Tips for Success with Yeast

• Use warm liquids around 100°F (38°C) to activate it.
• Proof in a warm, humid environment.
• Don’t overproof—gluten-free dough can collapse.
• Bake immediately after proofing.

Yeast is ideal for recipes that demand volume and softness, especially Asian breads and buns.

Baking Powder: For Quick and Consistent Lift

Baking powder is a chemical leavening agent containing both an acid and a base that activate when they contact moisture and heat. It’s the most versatile option in gluten-free baking because it works reliably in batters and doughs that don’t need fermentation.

How Baking Powder Helps Gluten-Free Baking

Since gluten-free mixtures can be dense, baking powder provides predictable lift that helps lighten the texture. It’s excellent in:

• Soft cookies
• Muffins and cupcakes
• Steamed cakes
• Donuts
• Pancakes and hotcakes

Double-acting baking powder (standard in the U.S.) works twice—once when mixed with liquid, and again in the oven—ensuring steady rising even if the dough lacks elasticity.

When to Use Baking Powder

Choose baking powder when you want:

• Fast rise
• Even, fluffy texture
• Stress-free results
• No fermentation time

Tips for Baking Powder

• Measure accurately—too much causes bitterness.
• Use fresh baking powder for maximum lift.
• Mix batters gently to avoid deflating the initial rise.

For cakes, pastries, and quick breads, baking powder is usually the best choice.

Baking Soda: Strong, Fast, and Best with Acidic Ingredients

Baking soda (sodium bicarbonate) is a pure base that needs an acid to activate and produce carbon dioxide. It’s extremely powerful and creates instant rise as soon as it meets an acidic ingredient.

Common acids used in gluten-free baking include:

• Yogurt
• Lemon juice
• Vinegar
• Brown sugar
• Honey
• Molasses

How Baking Soda Works in Gluten-Free Recipes

It helps lighten dense batters and reduces grittiness from rice or sorghum flours by reacting quickly and creating tiny air bubbles. It also improves browning and enhances flavor.

When to Use Baking Soda

Use it when recipes contain acidic ingredients and you need:

• Immediate lift
• Enhanced browning
• Tender, moist texture
• Subtle flavor improvements

Tips for Using Baking Soda

• Never substitute it 1:1 for baking powder.
• Too much causes a metallic taste.
• Bake the batter promptly—its leavening action is fast.

Baking soda is ideal in pancakes, cookies, brownies, and certain steamed desserts.

Choosing the Right Leavening Agent

The choice depends on the recipe’s texture and structure:

Best Leavening Agents for Each Recipe

Breads, buns & rolls → Yeast
Gives a slow, steady rise and creates great texture and flavor.

Cakes, muffins & quick breads → Baking powder
Provides a gentle, reliable lift for soft, fluffy crumb.

Pancakes, cookies & recipes with acidic ingredients → Baking soda
Creates a fast rise and helps with browning.

Steamed pastries → Baking powder
Ensures a consistent rise without collapsing.
