A cake turns out moist because of a combination of ingredients, techniques, and baking conditions that keep it from drying out. Here’s why your cake might be moist: Fat content – Butter, oil, or other fats coat flour proteins, reducing gluten formation and trapping moisture. Oil-based cakes usually stay moister than butter-only cakes. Sugar – Sugar is hygroscopic, meaning it attracts and holds onto water, which keeps the cake soft. Liquid ratio – Milk, water, juice, or yogurt in the batter adds moisture. Using too little liquid makes a dry cake. Eggs – Eggs provide structure but also add moisture and fat. They help trap air, which makes the cake light and tender. Acidic ingredients – Ingredients like buttermilk, yogurt, or vinegar react with baking soda to create carbon dioxide, keeping the cake airy and less dense, which helps it feel moist. Baking time & temperature – Overbaking is the most common reason cakes dry out. Baking just until a toothpick c...
