How to Make Baking Powder and Baking soda

Hi Bold Bakers!

I have been swamped with messages asking to show you how to substitute raising agents in your baking — including a baking soda substitute. Luckily, this is totally doable. Baking powder and baking soda are both baking essentials, and depending on the specific recipe you may need one or the other, or both. If you run out of one while you are baking I’m going to tell you how you can substitute it in a recipe!

Let’s start out with the what:

What Is Baking Powder?

It is a raising agent that reacts with moisture in your recipe to activate it and make your baked goods rise.  An example of this is: If you add baking powder to water you will see it bubble up and get fizzy.

How To Make Baking Powder Substitute

To make baking powder, mix together 1 tablespoon of baking soda and 2 tablespoons of cream of tartar. Cream of tartar is an acid and it is used to activate the baking soda in recipes. It is a by-product of winemaking.

What Is Baking Soda?

Baking soda is another raising agent, but it has to react with an acid in your recipe to activate it. By an acid, I mean a recipe that has buttermilk, yogurt, sour cream, vinegar and so on. If you add baking soda into vinegar you will see it bubble up and fizz over. That is the acid reaction.

How To Make A Baking Soda Substitute

For every 1 teaspoon of baking soda in a recipe, replace it with 4 teaspoons of baking powder — so use 4 times the amount of baking powder. The ratio is 1:4.

Notes on Yeast

Yeast, fresh or dried, is a raising agent for bread and dough. Now, you can use active dried or fast-action yeast. They are similar except fast action doesn’t require you to let your dough rise a second time unlike active dried yeast. Sorry, but there is no substitute for yeast in a recipe. You need to add it in for the recipe to rise.

But, not all bread needs yeast! Make my Traditional Irish Soda Bread or Best-Ever Banana Bread, for instance.

Hi Gemma!
I’m a newbie and your recipes are my guide. I’m planning to bake for our months old baby and I can’t find anything suitable to bake for this tiny human in your section. So, I decided to be bold and came up with a carrot muffins recipe baby version. Now, I’m stuck again, I can’t use baking powder or soda. I can’t get more adventurous than this, please help.

Hello Gemma
When making cookies, baking powder and baking soda are both used. So, how do we substitute the baking soda? Do we substitute every teaspoon of baking soda with 4 teaspoons of baking powder?

Hi Gemma,
Love your recipes and tips. Your baking soda substitutes is a bit confusing, replace baking soda with baking powder which contains baking soda? In this current climate, if People have not got baking soda, they cant use it to make baking powder? Have you other substitute tips please?
Thank you for your recipes!
