First, What Is Baking Powder?

To understand how to make a baking powder substitute, we need to understand what it is. Remember, I have a mind that loves science and if you’re gluten free, egg free, or corn free, you’re going to want to know the why so you have more success in the kitchen. Baking powder is a leavening agent and added volumes to baked goods (and items like pancakes). Baking powder also lightens the texture of your baked goods.

Without baking powder, items such as biscuits, cookies, and some breads would be more dense than you want. With gluten free baking, density is already an issue, so it’s important to get your leavening right to prevent more problems.

How Does Baking Powder Work?

Baking powder works by a combination of four key elements:

  • Alkaline Powder (such as baking soda)
  • Acid Salt
  • Neutral Starch
  • Liquid (added to your recipe)

When your baking powder combines with the liquid, carbon dioxide is produced. The gas is then trapped in the dough, which causes it to rise.

Corn Free Baking Powder – What’s The Big Deal?

If you’ve ever looked at the ingredients in baking powder, you most likely saw something like corn starch, monocalcium phosphate, and baking soda (sodium bicarbonate). For someone who can’t have corn, they’ll need a baking powder that has either potato starch, arrowroot, or tapioca starch. Whilst there are a couple of brands on the market that can serve the corn free community, as many learned during the pandemic, supplies are limited. It’s important that we all learn from 2020, and strive to be prepared where we can.

Cream of Tartar – All The Details

Did you know: if you have a grape allergy you can’t eat cream of tartar? Cream of tartar is a white crystalline acidic compound that’s obtained as a byproduct of wine fermentation. It’s mainly used in baking. As its derived from grapes, for those who can’t have grapes (and sometimes fermented products) cream of tartar is off limits.

Cream of tartar is the common name for potassium bitartrate (potassium hydrogen tartrate, KC4H5O6). For those who are cream of tartar free, you’ll need to use baking soda + an acid such as vinegar or lemon juice in your baking.

How Does Cream of Tartar Work in Baking Powder?

When you combine cream of tartar with baking soda (sodium bicarbonate) together they form a leavening agent. They do this by producing carbon dioxide gas.

Other Uses For Cream of Tartar

Cream of tartar can be used in cooking as well. You can add a little to boiling vegetables which will help them retain a fresh and bright color. You can also use it in whipped cream as a stabilizing agent.

What Is Baking Soda?

Sodium Bicarbonate, aka baking soda, is commonly used in baking, cooking, cleaning, and toothpaste. It’s a soluble white powder with a chemical formula of NaHCO3. Baking soda is one of the key elements that gives baking powder it’s leavening power. Interestingly, baking powder can be combined with other acids such as vinegar or lemon juice to create rise.

Baking Powder vs. Baking Soda

A lot of people who are new to baking sometimes think baking powder and baking soda are the same thing. In a nut shell, the difference between baking soda and baking powder is that baking soda is a single ingredient that’s an alkaline powder. When combined with other ingredients, it forms a leavening agent.

Baking powder on the other hand is a mix of usually three powdered ingredients (sometimes more) that when combined with a liquid create rise. When baking powder is used, ANY liquid will activate the reaction. If baking soda is used standalone, ONLY an acid can activate the rise.

Why Does Baking Powder Contain Starch?

The neutral starch in baking powder (usually corn starch or potato starch) is added to help prevent the absorption of moisture in the air. Remember when I said four key elements, and liquid was one of them? If moisture in the air gets into your baking powder, it can cause a reaction and ruin your dry mix.

Other Common Questions About Baking Powder and Baking Soda Answered

Can I use Baking Powder instead of baking soda?

That depends. In cookies, no. In pancakes, yes. If a recipe calls for baking soda + an acid, that’s the lift. In a pinch, you could replace it with baking powder + any liquid. However, if you’re following a blogger for their specialty recipes, I’d suggest sticking to what they use, as that’s the best way to produce identical results.

Does Baking Powder Go Bad?

Yes, baking powder can expire. When you purchase it, there should be a best by, use by, or expiration date on the package. If you purchase the individual component ingredients of baking powder, they may have a longer shelf life.
