It's very easy to make your own homemade baking powder that's keto approved.
The fact that the vast majority of baking powders currently on the market are not keto-friendly doesn't seem to be well known. I can't tell you how many “Keto recipes” I've come across that are using baking powder. It is something that is easy to miss. I mean really. Who would have thought?
The Baking Powder “Oops!”
I figured out that baking powder is not keto friendly by pure accident. I was converting a n
umber 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.
I instantly sat down on the computer and googled “Is baking powder keto?”. When I did this search, there wasn't much that came up. Digging through brand after brand of baking powder, I realized that the vast majority do contain cornstarch. Many of them also contain aluminum which isn't very healthy to ingest.
Cornstarch is derived from corn. Corn is a grain. We avoid all grains on a Ketogenic Diet.
Therefore, cornstarch is not keto-friendly.
Which means that the answer to the question “Is baking powder keto”? is…. Nope.
So what do we do?

Before making homemade baking powder, check your expiration dates!
It's sooooo easy just to use what's in our cupboard. If you're anything like me…the stuff in there could have been sitting in there for a year, or two, or three. I mean how much of this stuff do we really go through?
So, the first thing I did was check the expiration dates. My cream of tartar and baking soda were borderline, so I ran to the store and replaced them.
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).
For example– you could make a small batch of baking powder by mixing 1 tsp of baking soda and 2 tsp of cream of tartar in a small bowl.
This will yield 1 tablespoon of baking powder.
Note: I was totally tempted to make up a big batch of this but wondered if that would work. Unfortunately, pre-mixing seems to give flat results later on. But it's really not a big deal to mix this up quickly when baking.
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.
You'll notice carbs in the nutrition facts and this is because cream of tarter contains some carbs.
Add the baking soda to your dry mix and add the lemon juice into your wet mix. When you combine the dry and liquid mixes, you will notice a “foaming” reaction which is the acid from the lemon juice mixing with the baking soda and forming CO2.
Homemade Baking Powder with Vinegar
To make a substitute for 1 tsp of baking powder with vinegar:
In a small bowl, mix: 1 tsp baking soda and 1/2 tsp of citric acid. This yields 1.5 tsp of homemade baking powder. You can use this in your dry mix as a direct substitution for your baking powder.
A Few Notes On Homemade Baking Powder
When you are using homemade baking powder, it's important to quickly move your baked goods to the oven. Many of the commercial baking powders are “double acting” and contain aluminum. When the aluminum heats up, it creates a second reaction which helps give your baked product the texture and volume you desire.
Most of what I read on making your own baking powder recommends NOT making up a big batch in advance because the mixture will clump or lose it's potency quickly. It's really not that much work to substitute baking powder with a few simple ingredients.
You'll notice that my recipes on my YouTube Channel Tara's Keto Kitchen and here on this website are set up so that the work is done for you. You'll never have to use baking powder for one of my Keto recipes. (I do also have traditional recipes that were developed in my pre-keto days)

P.S. This was an excellent reminder for me to read labels. Even if it's just simple baking ingredients that I wouldn't even imagine could have something in it that I don't want to ingest.
