Hi Angie, I ice the styro with Royal Icing first then add my cake. As usual you have a cake circle under your cake to begin with. So no contact with the styro circle. I would use chocolate to attaché the cake to the base. You want the dowel to go thru the styro circle for stability . The cake circles,I ise under my cakes are coated so I have no,issues. I purchase them at Hobby Lobby, they are great! I hope you have a store near you. I don’t know if they have a store in Canada. Maybe online? If I didn’t answer all your ? Let me know
