Are Baking Soda and Baking Powder the Same?
Here’s the Real Difference Every Baker Should Know
When it comes to baking, beginners often confuse baking soda with baking powder. While both are leavening agents used to make baked goods rise, they are not the same—and using one in place of the other without adjustments can lead to baking disasters.
Let’s break it down in simple terms.
What is Baking Soda?
-
Chemical name: Sodium Bicarbonate
-
Formula: NaHCO₃
-
Type: Base
-
Reaction: Needs an acidic ingredient (like vinegar, yogurt, or buttermilk) to activate.
When activated, it produces carbon dioxide (CO₂) gas which causes the batter to rise and become fluffy.
🧁 Example Recipes: Chocolate cake, banana bread, buttermilk pancakes
What is Baking Powder?
-
Chemical name: A mix of baking soda + acid + starch
-
Type: Complete leavening agent
-
Double-acting formula:
-
First rise happens when mixed with liquid
-
Second rise happens during heating in the oven
-
You don’t need to add anything acidic when using baking powder—it already contains the acid.
🍰 Example Recipes: Vanilla sponge cake, muffins, cupcakes
Key Differences Between Baking Soda and Baking Powder
| Feature | Baking Soda | Baking Powder |
|---|---|---|
| Chemical Composition | Sodium bicarbonate | Sodium bicarbonate + Acid + Starch |
| Needs Additional Acid? | Yes | No |
| Taste if Overused | Bitter / Soapy | Mild |
| Type of Reaction | Single | Double-acting |
| Common Use | With acidic ingredients | With neutral ingredients |
Can I Substitute One for the Other?
Yes, but with the right formula:
To Replace 1 tsp of Baking Powder:
-
Use ¼ tsp baking soda + ½ tsp lemon juice or vinegar
To Replace 1 tsp of Baking Soda:
-
Use 3 tsp baking powder (but this may affect taste and texture)
🛑 Avoid direct one-to-one replacement unless the recipe is adapted.
How to Use Baking Powder Properly
-
Baking powder ratio to flour: Use 1 to 1½ tsp baking powder per 1 cup (120g) of all-purpose flour.
-
Does baking powder expire? Yes! Always check the expiry date. Expired baking powder won’t rise.
-
Storage tip: Store in an airtight container in a cool, dry place.
