Baking Powder vs Cornstarch: What You Need to Know
Baking powder and cornstarch are two common ingredients used in baking, but they have very different purposes.
Baking powder is a leavening agent, which means it causes baked goods to rise. It is a combination of baking soda and an acid, such as cream of tartar. When baking powder is mixed with wet ingredients, the acid and baking soda react to produce carbon dioxide bubbles. These bubbles create a light and airy texture in baked goods.
Cornstarch is a thickening agent. It is made from ground corn kernels and is used to thicken sauces, gravies, and other dishes. Cornstarch does not cause baked goods to rise.
Here is a table summarizing the key differences between baking powder and cornstarch:
Characteristic | Baking Powder | Cornstarch |
---|---|---|
Purpose | Leavening agent | Thickening agent |
Ingredients | Baking soda + acid | Ground corn kernels |
Reaction | Produces carbon dioxide bubbles | Thickens liquids |
Use in baking | Used to make baked goods rise | Not used to make baked goods rise |
Can baking powder be substituted for cornstarch?
No, baking powder and cornstarch cannot be substituted for each other. Baking powder is a leavening agent, while cornstarch is a thickening agent. They have different purposes and will not give the same results in baking.
Can cornstarch be substituted for baking soda?
No, cornstarch cannot be substituted for baking soda. Cornstarch is a thickening agent, while baking soda is a leavening agent. They have different purposes and will not give the same results in baking.
What is Baking Powder?
Baking powder is a leavening agent that helps your baked goods rise. It’s a mix of an acid and a base, usually cream of tartar and baking soda. When these two components come into contact with moisture and heat, they react to produce carbon dioxide gas, giving your dough or batter that fluffy lift.
Chemical Properties of Baking Powder
Baking powder contains both an acid and a base that react with moisture and heat. This reaction produces carbon dioxide gas, which is responsible for making your baked goods rise. The presence of cornstarch in baking powder keeps the alkaline and acidic elements dry until use.
Practical Uses of Baking Powder
Baking powder is essential in recipes that require a light and airy texture. Think cakes, muffins, and even some breads. It’s also your go-to for quick recipes like pancakes and waffles. If you’re out of it, a baking powder substitute like baking soda and an acid can often save the day.
What is Cornstarch?
Cornstarch is a thickening agent derived from corn kernels. Unlike baking powder, it doesn’t contain an acid or a base. It’s just a dense white powder that’s excellent at absorbing water.
Chemical Properties of Cornstarch
Cornstarch is primarily a thickening agent. It absorbs water well and is commonly used to stabilize and thicken recipes.
Practical Uses of Cornstarch
Cornstarch is your go-to for thickening sauces, gravies, and even some baked goods. It’s also a lifesaver for preventing your baked goods from sticking to the pan.
Tip: Cornstarch is also a great option for those with gluten sensitivities, as it’s a gluten-free thickening agent.
When to Use Baking Powder or Cornstarch

Baking Powder in Baked Goods
Baking powder is essential when you’re looking for a light and airy texture in your baked goods. It’s what gives your cakes, muffins, and cookies that perfect rise. For example, if you’re making a cake, the baking powder will react with the wet ingredients, creating bubbles that make the cake rise and become fluffy.
Cornstarch in Sauces and Gravies
Cornstarch is your best friend when you need to thicken a liquid. It’s commonly used in sauces, gravies, and puddings. For instance, if you’re making a gravy, a small amount of cornstarch can make it go from watery to wonderfully thick.
Key Takeaway: Always remember, baking powder for rise, cornstarch for thickness.
Can You Substitute One for the Other?
Baking Powder Substitutes
No, you can’t directly substitute baking powder for cornstarch. However, if you’re in a pinch, you can use baking soda and an acid like cream of tartar as a makeshift baking powder.
Cornstarch Substitutes
Cornstarch can be replaced with flour, but it’s not a 1:1 ratio. You’ll need to use twice the amount of flour, and it may give your sauce a slightly different texture.
Tip: Always mix cornstarch with a cold liquid before adding it to a hot one to avoid clumps.

Baking Powder vs Cornstarch for Wings
For chicken wings, it’s a matter of preference. Cornstarch will give you a crispier texture, while baking powder will make them a bit puffier.
