There has been much debate about what dowel rods to use when stacking a cake. I’ve seen everything being used from 1/4″ wooden dowels to custom support systems for stacked cakes. I’ve created a stacking method that hasn’t let me down yet. Knock on wood! I use the 1″ white plastic dowels from Pfeil and Holing and the 1/4″ wooden dowels from CK Products. With my method, the plastic dowels provide support for weight and the wooden dowels serve two purposes: support for weight and for stability right to left and back to front. This helps stabilize your cake from leaning or tilting. I will do a class on stacking cakes my way! As for the straw debate, well lets just say that straws have their place. In a glass!!!!
HERE IS AN EXAMPLE OF WHAT NOT TO DO!!! NEVER USE DRINKING STRAWS, CONTRARY TO WHAT YOU HAVE BEEN TOLD!!
Here are examples of the proper doweling/supports that I would recommend.
