How Cuthbert the Caterpillar Is Made (Step-by-Step Guide)
While exact recipes vary, most versions follow a similar production method. Here is a simplified breakdown:
Step 1: Baking the Sponge
A light chocolate sponge is prepared using:
Flour
Eggs
Sugar
Cocoa powder
Baking powder
The batter is baked in a flat tray to create a flexible sheet.
Step 2: Rolling the Cake
Once baked, the sponge is rolled while still warm to form a spiral shape. This creates the classic Swiss roll structure that forms the caterpillar’s body.
Step 3: Filling
A layer of buttercream or chocolate cream is spread inside before rolling fully.
Step 4: Cutting and Shaping
The roll is sliced diagonally and arranged in a curved “C” shape to mimic a caterpillar’s body segments.
Step 5: Coating
The exterior is covered in chocolate ganache or icing.
Step 6: Decoration
Decorations typically include:
Candy eyes
Chocolate feet
Colourful sweets along the back
A smiling face at the head
Practical Tips for Making Your Own Caterpillar Cake at Home
If you want to recreate a Cuthbert-style cake at home, here are useful tips:
Tip 1: Don’t Overbake the Sponge
A dry sponge will crack when rolled.
Tip 2: Roll While Warm
Rolling the sponge immediately helps prevent breakage.
Tip 3: Use Thick Filling
Too much filling will spill out; too little makes it dry.
Tip 4: Chill Before Decorating
This helps the coating set smoothly.

Soft sweets may melt or slide off.
