The rich, dense texture of cakes like carrot, red velvet and dulce de leche is a large part of their decadent appeal. But many other cake recipes aim for a fluffier texture and lighter, slightly less moist mouthfeel. Achieving this airiness requires the right combination of ingredients, the best tools for the job and the most effective techniques each step of the way.
Use real butter and cake flour in your recipe, and take your time creaming the butter, hand-mixing the dry ingredients and folding them all together to ensure a light and fluffy cake.
The Right Ingredients
The fluffiest cakes begin with the best ingredients. Use real butter rather than margarine or oil-based butter substitutes. Butter contains less water than margarine or other substitutes, and more fat. Water evaporates during cooking, which can leave your cake with a dry texture. Fat helps hold your cake together. Cake flour is a better choice for fluffy cakes than all-purpose or self-rising flour, because it contains cornstarch, which is lighter and has less natural oil than flour does. Make sure your baking soda and baking powder are fresh, because they can lose potency after sitting in your pantry for too long.
The Right Tools
A hand mixer or stand mixer is a definite asset for incorporating air into your cake batter. A hand-held whisk whips eggs and egg whites into fluffy clouds; a rubber spatula is useful when folding wet and dry ingredients together. Use a flour sifter for your dry ingredients. The finer the dry particles, the fluffier your cake will be, because the gluten chains will be smaller and finer.
The Right Techniques
Soften your butter to room temperature and it will be much easier to incorporate air into it. Cream your butter and sugar together with an electric hand mixer or stand mixer for 3 to 5 minutes. You can use a whisk or wooden spoon, but you will need to cream the butter and sugar for 5 to 7 minutes to get the right degree of fluffiness. Add the beaten eggs slowly into the butter and sugar, using your electric mixer to make a smooth, silky batter.
Whisk your dry ingredients together, and sift them into the butter, sugar and eggs. Don't use the electric mixer for this part, because if you get too much air into your batter, the cake will rise beautifully in the oven and then fall as it cools. Use a rubber spatula to gently fold the dry ingredients into the batter, and be careful not to overmix it.
If you don't have cake flour at hand, add 1 teaspoon of cornstarch to every 1 cup of flour to lighten it a bit.
