Yes, baking soda makes cakes fluffy by releasing carbon dioxide gas when activated by an acid and liquid, creating bubbles that make the cake rise and become light and airy, but it must have an acidic ingredient like yogurt or lemon juice to work; without an acid, it won't activate properly, leading to a dense cake. It's a powerful leavening agent, often used alongside baking powder in recipes with some acid but needing extra lift, notes Sally's Baking Addiction and Better Homes & Gardens.
Baking soda and baking powder are more common in recipes for cookies, cakes, and quick breads, and they are responsible for giving baked goods the light, fluffy, porous structure that makes them delicious.
By beating the batter while adding the sugar, the individual sugar granules will aerate the oil and butter mixture, creating the perfect base for a fluffy cake. Continue to beat the batter for 3 minutes until it is very pale yellow (almost white) and fluffy!
Through the chemical reaction created by combining baking soda with liquid, acid, and heat, carbon dioxide is created. These tiny CO2 gas bubbles allow for soft and airy baked goods such as cookies, pancakes, and cakes. Baking soda also increases pH levels while reducing gluten.
Try switching out any water in your recipe for full-fat milk or buttermilk for a moist, decadent texture. Another ingredient that can enhance the moisture of your cake is mayonnaise. Adding a dollop of mayonnaise to your batter can help make your freshly baked cake softer with an added boost of moisture.
This lends a bitter taste to the cake. But, in baking powder, tartaric acid is present to neutralize any effect sodium carbonate may have on the cake. The neutralization reaction of tartaric acid and sodium carbonate occurs and a salt called sodium tartrate is formed along with water.
How to create a fluffy light sponge. For the best results, always use room temperature butter and eggs. Cold eggs straight from the fridge make it harder to beat air into your mixture, while chilled butter can lead to lumps. Let them sit out for a bit before baking - it makes all the difference.
Flour Ratio: The amount and type of flour you use is crucial. More flour = more structure, which can lead to a denser texture. If you want a light, fluffy cake, you might want to use a lower protein flour like cake flour, which can help make the crumb of your cake more delicate.
Leavening Agents: Ensure that your baking powder and baking soda are fresh. These leavening agents help the cake rise and create a fluffy texture.

Too much baking soda is clearly not a good thing, creating too many bubbles in cakes, causing cakes to sink, leading to over-browning, and producing an off-flavour that might even be soapy.
Sometimes both are used in a recipe. When there is not enough acid included in a recipe, you can't just add more baking soda because it will give your finished product a metallic taste. Instead, baking powder is added in addition to the soda. In short, everything needs to be in balance.
Many professional bakers turn to simple syrup to help keep cakes moist until they are assembled and iced. To make your simple syrup, combine equal parts water and granulated sugar and heat on the stove, stirring until the sugar dissolves.
Add a leavening agent to the flour. Most cakes will call for a leavening agent like baking powder or baking soda. These create the bubbles you need for the cake to rise.
Professional bakers often rely on fat to help tenderise cake batters, ensuring a moist crumb that's not dry or crumbly. A key ingredient in achieving this is a high-quality butter or oil, which adds to the cake's richness. For a truly exceptional texture, consider integrating real butter.
It's very common to use baking soda in darker colored baked goods like chocolate cake or banana muffins. You do have to be careful though because as mentioned earlier, if you use too much, it'll leave a metallic or soapy flavor behind.
Baking powder is a mixture of baking soda NaHCO3 and an edible acid like tartaric acid. Baking powder on heating produces carbon dioxide gas which causes bread or cake to rise making it soft and spongy.
pH adjustment: baking soda increases the pH of baked goods, this may have an effect on color, flavor, crumb texture, and gluten strength. Texture improvement: creates a finer crumb. Adds flavor: in certain baked goods, it may provide a distinctive salty flavor.
Seven Bakery Secrets to Incredibly Moist Cakes Every Time
The simplest version of simple syrup, or soak, is nothing more than equal parts granulated sugar dissolved into water. The basic soak alone will do great things for your cake, especially in terms of moisture.
One big advantage of oil is that it's 100% fat, and fat equals more moisture and softness in baked goods. Meanwhile, butter is at least 80% fat, with the rest being mostly water. In the oven, this water evaporates out of the cake batter, giving the final dessert less fat and moisture overall.
