To make the cake layers a day ahead of time, bake and cool as directed, then place a slice of bread on each layer. Let stand at room temperature, and your cakes will stay fresh. The filling can also be made the day before assembling the cake.
For an extra-special touch, pipe frosting with a decorating bag and desired tip around top and bottom edges of the cake.
If you have extra raspberry filling, serve it over ice cream or atop your morning pancakes.
