How to stack a 3 layer cake for a professional and stable presentation?

To stack a 3-layer cake for a professional and stable presentation, start by placing the bottom layer on a cake board or serving plate. Spread a layer of frosting on top, then add the second layer. Repeat with frosting and the final layer. Insert dowels or straws into the cake to provide support, then chill the cake before serving to help it set and stay stable.
