What type of cake device is used to separate the square tiers?

Thank you!  Dan

It could be  small square boxes, or styrofoam blocks, or oasis (floral foam) completely covered with food-safe paper (butcher paper, cellophane, several layers of plastic wrap, etc.).

Hey Dan,

I have used the 7 inch push in pillars with a plate by Wilton for this style of cake. 

It was called a "tower of roses" cake.  My cake is 4 inches tall, so you have a 3 inch gap to fill with flowers.  This style used to be really popular.  It is a good design, so it comes back as a real classic look. 

As Shanter said you can also use Styrofoam spacers.  I just found the pillars to be easier.    

You could send a private message to the person who made the cake (MasterPiecesCakeArt) and ask.

you can also use the Bakery Crafts SPS.  There are adjustable pillars that would be just fine for a small gap.  I did one recently with a 4" space between tiers. the cake was very secure using the SPS. The roses were inserted on site.

Thank you!

Thanks!
