What Is Flexi Frost & Carve?
Flexi Frost & Carve is the ultimate solution for achieving flawlessly smooth cakes. Crafted from flexible yet sturdy, food-safe plastic, it provides the perfect balance of flexibility and firmness for applying ganache or buttercream.
Each set includes:
-
Two flexible frosting plates
-
A reusable food-safe carving template
-
A detailed picture tutorial
The plates peel away easily once your cake is set, leaving behind clean sides and sharp edges—without the need for parchment paper or cling film. Flexi Frost & Carve is also hand washable and reusable, making it a practical and long-lasting cake decorating tool.
Important Note: For the Round and Square Flexi Frost plates, you do NOT need to carve the cake. Therefore does not come with a carving template. The process for frosting the cake is the same.

Choosing the Right Flexi Frost Size
Before you begin, it’s important to select the correct size:
-
Consider Your Cake Tin
The carving templates are designed to fit standard cake tins. Follow the sizing guide when selecting your Flexi Frost & Carve so you know which cake tin to use. -
Perfect Frosting Thickness
Flexi Frost & Carve ensures a consistent ¼" layer of frosting on both sides of your cake for a professional-looking finish every time.
Tip: You can also use a larger cake or even a sheet cake, as long as you carve it to match the template.
Recommended Buttercreams
For best results, we recommend using:
-
Mock Swiss Meringue Buttercream
-
Italian Meringue Buttercream
These frostings provide the smoothest finish and release cleanly from the plates.
Step-by-Step: How to Use Flexi Frost & Carve
1. Carve Your Cake
-
Place the cutting template on your cake.
-
Cut straight down with your knife—do not cut at an angle.
-
This ensures clean edges and the correct shape for frosting.

2. Secure the Bottom Plate
-
Attach one Flexi Frost plate to a cake board using a few small dots of buttercream.

-
This keeps the plate stable while assembling your cake.

3. Stack and Fill
-
Place the cake within the marked lines on the bottom plate.
-
Fill and stack your cake layers as usual.
- Refrigerate your cake once stacked to ensure the buttercream is firm before moving on
-

Optional:
Apply a light crumb coat and chill the cake in the fridge to lock in crumbs and improve the final finish.

4. Prepare the Buttercream for a Smooth Peel
For the smoothest removal:
-
Take a small amount of buttercream and microwave it for 10–15 seconds.
-
Mix it back into your main batch to remove air bubbles.

-
Evenly spread this softened buttercream onto the Flexi Frost plate.

Flip the plate over and gently press it onto the cake. Use a scraper to ensure the plates are even, and scrape off any excess buttercream. Add the excess back into your bowl and stir to combine.

5. Frost the Sides
-
Pipe or spread thicker buttercream around the sides of the cake.

-
Use a scraper to smooth the buttercream, adding more where needed.
-
Continue scraping until the sides are smooth and even.

6. Chill the Cake
-
Place the cake in the fridge for several hours or overnight.
-
Chilling allows the buttercream to fully set, ensuring a clean release from the plates.
7. Remove the Flexi Frost Plates
-
Place a cake board on top and flip the cake to remove the bottom plate first.

-
Flip the cake back upright with another cake board on top.
-
Carefully peel off the top plate, starting from one side and then the opposite side for the cleanest peel.

If needed, fill in any small air bubbles with a bit of buttercream.
