Square Foam Cake Dummy

Square foam cake dummies give a cake a sharp, architectural line that a round tier can't. Every dummy is cut in-house from dense EPS foam to the exact side and height listed, with clean 90-degree corners and a smooth face ready to decorate straight out of the box. Sizes run from 4" to 22" per side, in 1" height increments from 1" to 10" — 148 size combinations in this shape alone.

Why our foam costs more than the cheap stuff

We cut from dense, fine-cell EPS with a closed surface — no visible beads, no pitting, no crumbling along the edges. Low-density foam is cheaper for a reason: the bead structure telegraphs through fondant, corners chip when you handle them, and the surface tears when you pull a dowel. On a square dummy that matters more than on a round one, because every flaw sits on a straight edge where the eye goes first.
