"I could not believe how beautiful my cake turned out using these rectangular acrylic discs! It was my first time doing a stacked sheet cake and I was so worried about sharp edges. But these acrylics made everything so easy! I’m so glad I bought them! CakeSafe to the rescue again!!!!" — Rita V., verified buyer

Sharp Corners or Rounded Corners — You Choose

CakeSafe® Sheet Cake Acrylic Disks are available in two corner styles so you can match your finish to your design vision. Select your preference at the time of ordering:

• Sharp Corners — for clean, defined edges with crisp 90 degree corners
• Rounded Corners — for a softer, classic sheet cake look

How Many Sheet Cake Acrylic Disks Do I Need?

CakeSafe® Sheet Cake Acrylic Disks are available in a quantity of 1 or 2 disks per size. We strongly recommend purchasing 2 disks per size for the most level, even edges: one disk goes on top of your cake and one goes underneath it. Some bakers choose to use just one disk — that works too, and we'll include modified directions either way.

What Size Sheet Cake Acrylic Disk Do I Need for My Cake?

Choosing the right size acrylic cake disk is important. Before ordering, measure your baked and cooled cakes to make sure you're getting the correct fit. Have questions? Call or email us — we're happy to help.

Here's our general sizing guide:

.5 inch sizing — Best for cakes that shrink less than 1/8 inch (or don't shrink at all) and will not be covered with fondant.

.25 inch sizing — Best for cakes that shrink more than 1/8 inch, or cakes that don't shrink but will be covered with fondant.

.00 inch sizing — Best for cakes that shrink more than 1/4 inch.

Do CakeSafe® Sheet Cake Acrylic Disks Have a Center Hole?

Yes — all CakeSafe® Sheet Cake Acrylic Disks include a 3/8 inch center hole. Bakers use this hole to stabilize their cakes by threading a temporary dowel through it while they're icing. This is especially useful if you don't have time to refrigerate your assembled tier to set it before icing. Don't need it? No problem, the center hole has zero impact on how the disk performs.
