Cake dummies come in standard diameters matching pastry molds (15, 18, 20, 22, 25, 28, 30, 35 cm) and variable heights (5, 7.5, 10, 15, 20 cm):

• Layered wedding cake: combine several decreasing diameters (35 + 28 + 22 + 15 cm) with height 10-15 cm each
• Simple display case: one dummy Ø 20-25 cm height 10 cm is enough
• Layered photoshoot: 2-3 complementary diameters
• 3D cake design sculpture: tall dummies (15-20 cm) or stacked and carved

High-density polystyrene offers three essential advantages for cake design:

1. Perfectly smooth surface: no grain or bubbles visible through the fondant, unlike standard polystyrene
2. Sharp edges: straight edges and precise angles, essential for geometric wedding cakes
3. Higher density: supports aggressive techniques (rod nailing, sculpting), resists light impacts and the weight of decorations

Avoid low-quality cake dummies (visible alveolar polystyrene) that deform when covered and give a poor finish.

The round remains the universal standard: elegant, timeless, compatible with all styles. The square offers a modern and geometric look, perfect for contemporary wedding cakes and design blocks. The hexagonal and other shapes (heart, star, flower) serve specific themed projects (botanical weddings, original birthdays, brand events).

To start a cake designer collection, begin with 3 rounds of different diameters (Ø 20, 25, 30 cm) then add shapes as projects progress.

Indicative estimates for a dummy 10 cm high:

• Ø 15 cm: 500 g of fondant
• Ø 20 cm: 700 g
• Ø 25 cm: 1 kg
• Ø 30 cm: 1.3 kg
• Ø 35 cm: 1.6 kg

Always buy 15 to 20% more than the estimate to manage scraps and have a margin in case of coverage mistakes.

A decorated cake dummy can last several years under suitable conditions: protected from direct moisture, UV rays (which yellow white fondant), and shocks. Ideal for shop displays: decoration is replaced once a year if you want to keep a fresh look, but the dummy itself is reusable indefinitely.

Yes, this is the premium use. Stack decreasing diameters using support rods (dowels) that go through the tiers, just like a real tiered wedding cake. High-density polystyrene perfectly accepts nailing the rods. You can then decorate each tier independently before assembling them. Part of the wedding cake can even be real (top tier for the symbolic cutting) and the rest as dummies.

If you want to reuse a cake dummy after use, remove the fondant with a thin spatula without damaging the surface. For stuck residues, use a damp cloth (not soaked). Avoid heavy washing with water which weakens the polystyrene. Store dummies flat or stacked in a dry cupboard. With proper care, a dummy can be reused dozens of times.

Many event pastry chefs combine both: top tier as a real cake (for the symbolic cutting by the couple) and lower tiers as cake dummies covered with fondant identical to the real one. Guests are then served with cut cakes prepared in the kitchen. Advantages: impressive presentation, simplified transport, controlled cost, zero waste. Standard solution among high-end wedding planners.

The polystyrene used for cake dummies is food contact compliant according to European regulations. However, the cake dummy is not designed to be eaten and any sugar paste in direct contact will also not be consumed. For mixed wedding cakes (real cakes + dummies), clearly inform servers and guests about the real vs decorative tiers.

Yes, it is even one of the advanced 3D cake design techniques. With a heated cutter or a heated polystyrene wire, you can carve the dummy into desired shapes (animal, character, object) before covering. The high density of the polystyrene allows clean cuts without crumbling. Ideal for exhibition and competition cake sculptures.

Recommended basic investment for a professional cake designer: 3 round cake dummies Ø 20, 25, 30 cm height 10 cm. This set covers 80% of common needs (display, photoshoot, training demos, simple wedding cakes). Then add specific shapes (square, tall, mini) as projects evolve. A durable investment since dummies do not expire.

Yes, it is the ideal option for themed birthday parties where the central cake is purely decorative (photo, game, animation). The dummy allows spectacular decoration (figurines, fondant, sugar paste flowers) without time constraints. Also perfect for baby showers, gender reveals, and corporate events where visual impact is key.
