Check the expiration date on your yeast, baking soda, and baking powder.
Test your yeast:
But one cup of warm water, 1 tsp of sugar and 1 Tbs of yeast in a bowl together and let sit for 10 minutes. Make sure it has begun to expand and bubble.
Test your baking soda:
Mix a tsp of vinegar and a tsp of baking soda together. It should bubble like a 2nd grade volcano science experiment. If it doesn't, it is time to get some new baking soda
Test your baking powder:
Put a tsp of baking powder in a cup of hot water. It should bubble and spat (it is releasing carbon dioxide). If it doesn't, it won't help your baked goods rise and you need some new baking powder.
