Steps

Per one teaspoon of baking powder asked for in a recipe, you’ll need: 1/2 teaspoon cream of tartar and 1/4 level teaspoon bicarbonate of soda (baking soda)
Mix the cream of tartar and baking soda in a small bowl. Optionally add cornstarch (or arrowroot powder) if you aren't using it immediately to stop the two ingredients from reacting/clumping and to extend the shelf-life.
Either use it immediately or transfer it to a small airtight container.Note: homemade baking powder substitute won't be "double-acting," so be quick to get your bake into the oven after adding the powder to your batter/dough.
What if I don't have cream of tartar?
- You can achieve the same effect by combining baking soda with another acid. For example:Instead of 1 teaspoon baking powder: use ¼ teaspoon baking soda + ½ cup buttermilk.Simply use the buttermilk in place of other liquids in the batter. Obviously, this method only works with recipes that contain lots of liquid in the batter.

My daughter is allergic to corn and wheat, so we used this in recipes without the arrowroot. So happy to have an alternative for baking powder to use with cassava flour which has a tendency to be flat and gummy.
