Frequently asked questions
Can I replace the hazelnut flour with another ingredient in this recipe?
Hazelnut flour is the star flavor of this recipe, and replacing it with another ingredient would completely change the taste and texture of the cake, so I do not recommend swapping it. However, if you are looking for other recipes, feel free to browse my blog where you will certainly find options to suit your needs.
Can the cake be frozen for longer storage?
Yes, you can freeze the cake to keep it longer. I actually recommend it, as this cake is particularly rich and a small slice is often enough. Freezing individual portions allows you to enjoy them at your own pace without worrying about the cake spoiling.
Is it possible to replace the dark chocolate with milk or white chocolate?
It is possible to replace the dark chocolate with milk or white chocolate in this recipe. However, I do not recommend it. Dark chocolate is perfectly suited for this recipe because it is less sweet and pairs particularly well with the subtle flavor of hazelnut.
