A dry and dense cake is often caused by overmixing the batter, using too much flour, or baking at too high a temperature. Adjusting these factors can significantly improve the cake's texture.
Several factors can contribute to a dry and dense cake. Let's break them down:
Overmixing: Overmixing the batter, especially after adding the flour, develops too much gluten. Gluten is a protein in flour that creates structure. Too much gluten results in a tough, dense cake. Mix until just combined.
Too Much Flour: Using too much flour throws off the wet-to-dry ingredient ratio. This leads to a dry cake because there isn't enough moisture to hydrate all the flour. Always measure flour accurately, preferably using a kitchen scale. Spoon the flour into the measuring cup and level it off, instead of scooping directly from the bag.
Oven Temperature Too High: Baking at a temperature that's too high can cause the cake to cook too quickly on the outside, trapping moisture inside and leading to a dry interior. Ensure your oven is properly calibrated and use an oven thermometer to verify the temperature.
Incorrect Fat to Sugar Ratio: Fat and sugar contribute to the moisture and tenderness of a cake. If the recipe has too much sugar relative to the fat, the cake can become dry.
Stale Ingredients: Using old baking powder or baking soda can affect the cake's rise and texture, potentially leading to a denser result.
Always use room-temperature ingredients, especially butter and eggs. Room-temperature ingredients emulsify better, creating a smoother batter and a more tender cake. This helps to retain moisture and prevent a dry outcome.
