To get crushed kit-kat fingers, you can place the fingers in a dry grinder and crush into smooth or crumbly texture. At the same time, you can also crush the fingers by breaking them into pieces and then placing them between two sheets of butter paper or wax paper and crushing them using a rolling pin to a desired consistency. They can be crushed coarsely or finely as per the recipe requirement.

Kit Kat fingers are slender crispy wafer fingers covered with creamy milk chocolate, which are attached to each other to make up a complete bar. These individual fingers are generally used for decorating and garnishing desserts like cakes, pastries, gateau etc.
