Mixing the dry ingredients with the fat first—a technique known as the "high-ratio method"—helps create a fine, tender crumb and a light, airy texture in the cake. By coating the flour with fat, we minimize gluten formation, preventing a tough texture. Adding the liquid ingredients in stages then helps to create an emulsion that incorporates more air into the batter, resulting in a moist and fluffy cake. This method produces a texture similar to fluffy store-bought cake mixes, which is nearly impossible to achieve with the traditional creaming method.
