Yes, using cake boards between tiers is highly recommended when creating a multi-tiered cake. Cake boards provide essential structural support by distributing the weight evenly across each layer while preventing them from sinking into one another under pressure. They offer stability during transit and help maintain the integrity of the overall design. Additionally, they make it easier to handle individual tiers during assembly and allow for smooth separation when it comes time to serve the cake. Cake boards can be made from various materials such as cardboard or food-grade plastic but should always be appropriately sized to fit the cake tiers.
