So, the other day, I was all set to bake some muffins. Got all my gluten-free flour out, the eggs, everything. Then I reached for the baking powder and had one of those “uh oh” moments. I wasn’t entirely sure if my store-bought one was 100% gluten-free, or maybe I just plain ran out. It happens, right? You think you have something in the pantry, and poof, it’s gone, or you start second-guessing ingredients when you’re trying to be careful about gluten.
My Little Kitchen Experiment
Anyway, I wasn’t about to let that stop my muffin mission. I remembered reading somewhere that baking powder is basically a mix of a couple of things that create bubbles when they get wet and warm. So, I thought, why can’t I just whip up my own little batch? It’s not like it’s rocket science, or so I hoped.

I rummaged through my spice cabinet and pulled out the essentials: baking soda (sodium bicarbonate, if you want to get fancy, but who does?) and cream of tartar. These are the usual suspects.
Here’s what I did, and it was pretty simple:
I got a small, clean, dry bowl. That’s important – you don’t want it reacting before it hits the batter.
Then, I took out my measuring spoons. I decided on a common ratio I’d seen mentioned: two parts cream of tartar to one part baking soda. So, I measured out 1 teaspoon of baking soda and put it in the bowl.
Next, I added 2 teaspoons of cream of tartar to the same bowl. Easy peasy.
Now, some folks add a bit of cornstarch or another starch to keep it from clumping and to sort of standardize it, make it more like the store-bought stuff. Since I was aiming for strictly gluten-free and sometimes corn can be an issue for super-sensitive people (though usually it’s fine), I thought about using arrowroot powder or tapioca starch. I had some arrowroot powder, so I tossed in 1 teaspoon of that as well. This also helps absorb any tiny bit of moisture that might be hanging around.
I gave the whole mixture a really good stir with a small whisk. You want it all evenly combined, so you don’t get a big hit of baking soda in one bite of your muffin – yuck!

Did it Work?
So, I had my little bowl of homemade, gluten-free baking powder. I used it straight away in my muffin recipe, measuring it out just like I would with the regular stuff. I was a bit nervous, not gonna lie. You know how it is when you try something new in baking.
But guess what? The muffins rose beautifully! They were light and fluffy, just like they should be. Success! It felt pretty good to have made my own, and now I know for sure exactly what’s in it. No weird additives, no gluten worries. Plus, it’s handy to know how to make it in a pinch if I ever run out again. So yeah, that was my little kitchen adventure for the day. Worked out pretty well, I’d say.
