There are many traits that make up a desirable cake, such as rich flavor, creamy frosting and moistness. While the first two qualities can often be achieved with few problems, many bakers have trouble achieving a cake that’s moist all the way through. Various techniques can be employed before, during and after the cake-baking process to ensure your cake is moist down to the last bite.
Things You'll Need
Add additional sugar and oil to the cake mix. Ingredients like granulated sugar and oil store and preserve moistness while substances like flour dry out a cake. Put in 1 1/3 cup sugar for every 1 1/2 cup of flour or add an additional 1/4 cup of oil to your cake batter.
Add an extra egg yolk to the cake batter. Egg yolks contain moisture and distribute that moisture throughout the cake batter, while egg whites absorb moisture. Alternatively, remove the whites from the eggs the recipe says to put in your cake.
Add 1/4 cup mayonnaise to your cake instead of extra egg yolk, sugar or oil. Mayonnaise contains fats and oils that lock in moisture as well as vinegar, which is a natural preservative. Since you’re adding such a small amount, the mayonnaise won’t alter the flavor of your cake.
Don’t overbake the cake. Use an oven thermometer to verify that your cake is baking at the correct temperature and use an oven timer to ensure you don’t leave the cake in the oven longer than the recipe calls for and dry it out. Look in on your cake often during the baking process as well.
Wrap up and freeze your cake. Allow your cake to completely cool on a cooling rack after it has finished baking. Wrap the entire cake in plastic wrap so it is completely covered. Wrap the cake again with aluminum foil. Place the cake in your freezer for at least four hours (preferably over night). Remove the cake from the freezer, unwrap it and immediately frost it. As the cake unfreezes, the moisture will be locked in by the layer of icing.
Store your finished cake in an airtight container. This helps lock in the moisture of the cake and prevents the air from drying out the cake. You can also cover any unfrosted areas exposed after cutting into the cake with plastic wrap.
