Homemade Baking Powder

With the winter storm that came through yesterday, we knew our bi-weekly trip to Miles City needed to be taken early.  I always look forward to this trip so I can stop in at the Vincent de Paul thrift store. It's the only thrift store in Miles City and I really enjoy stopping in there. Since we had to make our trip during the week, I would not be able to stop in because they would be closed. I tell ya, I'll be ready to visit in 2 weeks!

I have quickly learned that the Miles City Walmart is HORRIBLE, HORRIBLE, HORRIBLE about keeping their shelves stocked throughout the day. Because of this, I have to either do without or use a different brand. While I was there on Wednesday, the flour section of the isle was totally bare of all the flour.  I looked and found one bag of all purpose flour on the bottom shelf tucked behind a bag of corn meal. Anyone who knows me, knows I really dislike buying all purpose flour. I keep bread flour in the freezer for my breads, but all purpose flour and having to add salt, soda and baking powder is just a nuisance for me. Why not just use self rising, everything is already in there?!  Of course, I grabbed the last bag of flour.

Earlier this week, I began researching baking powder on the internet. I have a cake I'm planning on making next week that calls for cake flour. I don't buy cake flour, so I knew I was going to have to use all purpose.  Since this cake is a childhood favorite and I've never made it before, I wanted to make sure I use what the recipe calls for.  Since I always buy self rising flour, I decided I would make my own baking powder for this cake recipe. Yep, you read that correctly! I made my own baking powder on Thursday; and it works! I made a test pan of biscuits using the homemade baking powder and they were beautiful. So beautiful they were eaten before I got a picture of them.

Baking powder consists of ingredients that are in most kitchens.

Homemade Baking Powder

The good thing about making your own baking powder is you can make however much you need from several teaspoons to a cup. Of course, making your own means there's no aluminum that is in the store bought.

Homemade Baking Powder


  • 1 teaspoon baking soda

  • 2 teaspoons cream of tartar

  • 1 teaspoon cornstarch

For making a cup of baking powder:

  • 1/4 cup baking soda

  • 1/2 cup cream of tartar

  • 1/4 cup cornstarch


Mix the ingredients well and use as your normal baking powder. Store in an airtight container.
