Quick Tip

Make sure everything is mixed thoroughly. Cornstarch is known to clump up. So, you’ll want to mix out all of the lumps.

How to Store Homemade Baking Powder

You’ll want to keep the homemade baking powder in an airtight container. This ensures it keeps its freshness long after you make it.

One of the best airtight containers to use is a mason jar. The jar has a tight-fitting lid that makes sure the homemade baking powder stays nice and fresh. Plus, it has a large mouth to get the right amount of powder out. That way it doesn’t spill all over the place.


How long does homemade baking powder last?

For best results, homemade baking powder should be used in the first six months. After that, you may notice that it’s less powerful and might have some problems in your recipes.

Is baking powder shelf stable?

Yes! It is best to keep baking powder out of the fridge in a cool and dry place.

How can I tell if my baking powder is still good?

Baking powder can become less potent over time. To check if it’s still good, pour 1/4 boiling water over 1/2 tsp of baking powder. If the powder bubbles, it is still in good shape. If you don’t see any bubbles, it is time for a new batch.
