The difference between a single acting and a double acting Baking Powder is their chemical composition and whether they produce the carbon dioxide gas bubbles that make your baked goods rise when the ingredients are mixed or when the product is heated in the oven.
Single-acting Baking Powder reacts with a water-based ingredient to form bubbles as soon as the ingredients are mixed. If you wait too long to bake your food or mix it too long these bubbles will escape and your food will fall flat.
Double-acting Baking Powder produces some bubbles when the ingredients are mixed, but most of the rising occur once heat is applied. This product is more reliable for home baking because it is harder to overbeat the ingredients and the recipe is less susceptible to fail if you forgot to preheat your oven.
