Homemade Baking Powder and Buttermilk

Don't you hate when you're in the middle of baking something and then notice that the recipe calls for an ingredient that you have either used up or rarely buy? Over the weekend I was making cinnamon rolls and halfway through the recipe I realized that I had used up all my baking powder (on these delightful griddle cakes) and didn't have any buttermilk in the fridge. Oh the tragedy.

Luckily, both buttermilk and baking powder are easily made at home.

To make buttermilk, just add 1 tsp. of white vinegar to 1 c. of milk. Let it sit for about a minute and the vinegar will both thicken and slightly curdle the milk. You'll want to use it quickly because if you try to make this in advance, it can sometimes cause the milk to separate after a bit.

When truly desperate, I've actually used this "buttermilk" in the place of sour cream in baking recipes. Just add in 1/2 c. more flour and you'll be good to go.

Now for the baking powder:

Just combine 1 tsp. baking soda, 2 tsp. cream of tartar and 1 tsp. corn starch; sift together.

Wasn't that ridiculously easy?
Store the baking powder in an airtight container. I picked a few of these cute mini canisters up at Michaels and they've come in really handy for storing spices and whatnot.

Are there any ingredients you've tried making? Did they work or did they flop?


  1. Wowser. I knew you could make buttermilk but I had no idea about the baking powder. Do you think it helps catch odors like the stuff you buy in the store?

    I like to make my own "cream soup" mixes and my own dry onion soup mix. They are always a success.

    I had a recipe once that needed 1/2 and 1/2 and I didn't have any so I googled it and found you could take milk and add butter to make it 1/2 and 1/2. FLOP!

  2. I have also heard that you can take a tablespoon of lemon juice to one cup of milk for "buttermilk". What do you think?

  3. Reagan - Since it has baking soda in it, I'm sure it would help catch odors. I would love it if you would share your dry onion soup mix!

    Annie - I've never tried that method before but if you do, please let me know how it turns out. Since it is the acidity in vinegar that turns milk into "buttermilk" it just might work to use a lemon.


I love feedback from y'all and try my best to respond to as many questions as possible.
