Cake Cooling Tip: When cooling cake layers, place bread slices on top to keep the cake layers soft and moist while the bread becomes hard as a rock -- What a fun fact. My mom told me it keeps it from cracking in the middle too. @Patty Kelly
Never knew this...bake cake layers the night before, leave out on counter with slice of bread on top so that the cake will not become stale. use this same trick with muffins, cupcakes. - I never knew this!
