The Frost Form heart kit lets you ice a heart-shaped cake with a smooth, clean finish, without advanced spatula skills. The principle: a rigid frame and a flexible sheet guide the icing, creating straight, even edges in a single chilling step. Available in two sizes: 15 cm and 20 cm.

How it works
- Cut the cake layers with the Crumb Cutter.
- Secure the liner base to the former base with a little icing.
- Center the cake, wrap the liner around it, and clip it without folding.
- Slide the whole assembly into the rigid structure, fill with ganache, and smooth the top.
- Refrigerate for 3 to 4 hours (or 45 to 50 minutes in the freezer), then unmold and finish the seam with a spatula.
Store the liner rolled up or in its base so it retains its shape. If it becomes wavy, run it under hot water: it will lie flat again. A ganache (dark or milk chocolate) is recommended for your first attempts.
Frequently asked questions
How does the Frost Form work?
The rigid frame and graduated flexible sheet hold the icing in place while it chills, creating clean edges without advanced spatula work.

The 15 cm size is suitable for standard cakes, while the 20 cm size is ideal for larger cakes and special occasions.
How do I care for the flexible liner?
