The use of baking powder in some cakes allows to obtain a light texture because baking powder contains chemical fermentation agents that release carbon dioxide during baking, creating air bubbles that make the dough rise. On the other hand, the baker's yeast used in bread acts over a longer period and is not suitable for obtaining a airy texture in cakes.
Baking powder is a leavening agent widely used in baking to help cakes rise and achieve a light and airy texture. It generally consists of sodium bicarbonate (or baking soda), cream of tartar (or tartaric acid), and a starch to absorb moisture and prevent a too rapid reaction of the other components.
Sodium bicarbonate is a chemical base that reacts with tartaric acid, an acidity, when combined with the addition of water or a liquid. This reaction generates carbon dioxide, a gas that creates bubbles in the cake batter, causing it to rise and increase in volume.
Some baking powder manufacturers also add stabilizing agents or anti-caking agents to ensure the quality and longevity of the product. It is essential to follow the recommended amounts of baking powder in a recipe, as an excess can give a bitter taste to the cake and a lack can result in a too dense and compact batter.
Compared to yeast, baking powder does not require resting time to make the dough rise, making it convenient for quick cake and pastry recipes. Its specific composition allows for an instant chemical reaction during baking, ensuring a light and fluffy result that will please dessert lovers.
When baking a cake with baking powder, a chemical reaction occurs. Baking powder is composed of sodium bicarbonate and cream of tartar, two ingredients that react together in the presence of moisture and heat. This chemical reaction is called an acid-base reaction. When the cake batter is heated in the oven, the heat causes the decomposition of sodium bicarbonate, releasing carbon dioxide in the form of bubbles. This gas accumulates in the batter and causes it to rise, giving the cake its airy and light texture. The formation of these air bubbles is essential to achieve the desired texture in a cake baked with baking powder.
When baking powder is added to the cake batter and the mixture is then heated during baking, a chemical reaction occurs. This reaction releases carbon dioxide (CO2), which forms air bubbles in the batter. These air bubbles are responsible for the lightness and airy texture of the cake. In fact, the air bubbles trapped in the batter expand due to the heat of the oven, giving the cake its light and fluffy structure.
Baking powder promotes the light texture of cakes thanks to the chemical reaction that occurs during baking. With heat, baking powder releases carbon dioxide, forming air bubbles inside the batter. These trapped air bubbles help aerate the cake structure, making it lighter and fluffier. In comparison, baker's yeast is often used for breads, requiring a denser and more elastic texture. Therefore, using baking powder instead of baker's yeast in some cakes allows achieving the light and airy texture sought after by many pastry enthusiasts.
Baking powder usually contains acidic phosphate salts and an acidic reaction agent, such as cream of tartar, which react together to produce carbon dioxide, responsible for aerating cakes.
Baker's yeast, on the other hand, is composed of living microorganisms, natural yeasts that ferment the sugars present in the dough to produce carbon dioxide. This fermentation is slower than the reaction of chemical yeast, hence the difference in texture obtained.
The use of baking powder allows for faster preparations, as there is no need to let the dough rest to allow the yeast to develop, unlike when using baker's yeast.
To achieve a light and airy texture in cakes, it is important not to overmix the batter once baking powder is added, in order to preserve the carbon dioxide bubbles formed during the chemical reaction.
Baking powder is a leavening agent that reacts chemically with other ingredients to make the dough rise, while baker's yeast is a living microorganism that ferments the dough to make it rise.
Baking powder reacts with liquids and heat from the oven to produce carbon dioxide gas, forming air bubbles that make the dough rise.
Baking powder allows to obtain a light and airy texture in cakes, unlike yeast which can give a denser texture.
Baking powder acts more quickly, doesn't require resting time, and doesn't add any distinctive flavor like yeast does.
No, because baker's yeast also brings specific flavors and a particular texture to breads and brioches that cannot be replicated by chemical yeast.
