It’s recommended to use a thin serrated knife; they made neater slices with fewer frosting smears and crumbling. With a serrated knife you can use a gentle sawing motion, so the knife moves through the cake without compressing each slice to avoid crumbling rather than cutting straight down.
Actual number of servings will depend on how big or small you cut each slice.
For TRANSPORTATION: Place your cake on a flat level surface, such us in the trunk or in the Floor of the car. Drive cautiously.
