Why make your own homemade baking powder?
If you are following a grain-free diet such as a Ketogenic Diet or the Wheat-Belly Diet then you'll want to avoid baking powder because it contains cornstarch.
Or, maybe you're in the middle of a recipe and realized you don't have baking powder in the house.
Here, I'll share four ways you can make your own baking powder with common household ingredients.
The Down Low On Baking Powder
It's very easy to make your own homemade baking powder that's keto approved.
The Baking Powder "Oops!"
I figured out that baking powder is not keto-friendly by pure accident. I was converting a number of my favorite quick bread
recipes to keto versions. (I've been creating recipes since I was 15 and was challenging myself by learning how to cook with keto flours). Anyhow, I flipped over the baking powder can and looked at the ingredients.
eeeeek! Cornstarch!
Which means that the answer to the question "Is baking powder keto"? is.... Nope.
So what do we do?

4 Ways To Make Homemade Baking Powder
All of these recipes use acid-base reactions. The base in all of these recipes is baking soda (sodium bicarbonate).
The acid in each recipe varies.
For the Cream of Tartar & Citric Acid recipes, simply add these into your dry mix.
When you are working with a liquid (vinegar or lemon juice), add that into your wet mix and the baking soda into your dry mix.
When you get to the part of your recipe where you mix wet and dry ingredients, you'll see a "foaming" reaction as the acid-base creates CO2.
How To Make Homemade Baking Powder with Cream of Tartar
Homemade Baking Powder
Ingredients
- 1 teaspoon baking soda
- 2 teaspoons cream of tartar
Instructions
- To make your grain-free baking powder, all you need to do mix baking soda and cream of tartar
- Use the adjuster in this recipe card to adjust how much you want to make. One batch will yield 1 tablespoon of baking powder.
- You should use this right away. It's generally not recommended to make this homemade baking soda in a large batch and store it in the cupboard because it will lose its effectiveness. However, I find it is very fast and easy to mix this up quickly when baking.

The amount of carbs in the baking powder from store due to cornstarch is so minute. Typically it’s 1.5 grams for your entire recipe.

After my kids anaphylactic episode, I learned to read everything even if I had used the product before. Those stinkin' companies are always fiddling with ingredients. Probably trying for cheaper.

If you look carefully, you can find baking powder that is kosher for Passover and therefore contains no cornstarch or any other grain. I use it all year round with perfect results every time.

Wow, so much knowledge! Thanks! Do you have any recommendation for a leavening agent to use in fathead dough that you do NOT cook right away? Making the dough and freezing has been a time saver, but would like to fluff it up a bit.
Tara Wright, CHC, MBA says
Great question. I have never actually tried freezing the fathead dough. If I were going to try that, I'd start with 1/2 tsp baking soda to experiment!
