Baking powder

Baking powder is a chemical leavener used in cakes and other baked sweets. It is not baker’s yeast, which works through fermentation.

Chemical leavening
Baking powder combines raising agents that react during mixing and heating; the exact blend varies by product.
In Italian cakes
Baking powder gives added lift to hazelnut cake batters; some versions of sbrisolona also use it.
Use the recipe dose
Packet size and formulation vary, so follow the dose and method for the product you buy.

Mix and bake promptly

Measure the baking powder specified by your recipe and distribute it evenly through the dry ingredients. Add it at the stage the recipe directs, then bake in a preheated oven; chemical leaveners are not a substitute for a yeast rise.

For cake batters and crumb doughs

Use cake baking powder in recipes that call for it, such as a hazelnut cake or a crumbly sbrisolona. Some Italian packets are aromatic, while others are unflavoured; check the label when the recipe’s flavor balance matters.

Read the packet

Choose a product labeled for cakes or baked sweets and check its instructions, dose and ingredients. Do not swap it gram-for-gram with fresh or dried baker’s yeast.

Keep it dry

Store the packet according to its label and close it against moisture after opening.
