The crunch cake is versatile and can take on different flavors and profiles without losing its core idea: soft crumb, creamy layer, and crunchy topping. Below are variations that keep the essence of the recipe and let you create unique versions to surprise—and even boost sales.
Crunch cake with Nutella
For hazelnut spread lovers, this version is pure indulgence. Just replace the Ovomaltine cream with Nutella, keeping the corn flakes to preserve the defining crunch of the crunch cake.
How to make

If you want a more delicate, visually elegant dessert, go for the white version of the crunch cake. Here, white chocolate takes the place of semisweet.
How to make
• Use good-quality white chocolate
• Swap the flakes for rice crisps for a light, even crunch
• Make a white ganache to keep a clean, sophisticated look
Result
Milder flavor, light texture, and a delicate appearance—ideal for parties and events.

Creamy caramel crunch cake
This version elevates the crunch cake with a thin caramel layer between the ganache and the crunchy part. The union of chocolate and caramel adds depth of flavor and a richer mouthfeel.
How to make
• Prepare a creamy caramel or use caramelized dulce de leche
• Spread a very thin layer over the ganache
• Add the crunchy topping on top and let it set
