Which tools are needed for frosting cake with a knife?

Some essential tools for frosting a cake with a knife include:

1. A long, flat knife: The blade of the knife should be smooth and straight, with no serrations or teeth, to create a smooth and even frosting layer.

2. A turntable: This rotating platform allows for easy access to all sides of the cake while frosting, ensuring an even layer of frosting on each side.

3. Offset spatula: An offset spatula is a handy tool that helps reach difficult areas such as corners and edges.

4. Piping bag: A piping bag can be used to add decorative details or patterns to the frosted cake.

Using these tools in combination with a steady hand and patience will help you achieve professional-looking results when frosting your cake with a knife.

How to smooth out the frosting using a bench scraper or offset spatula?

To smooth out frosting using a bench scraper or offset spatula, start by applying a thick layer of frosting to the cake. Hold the bench scraper or offset spatula at a slight angle against the side of the cake and slowly rotate the cake while holding the tool steady. This will help create a smooth, even layer of frosting on the sides of the cake. With practice, you can achieve a professional-looking finish that is sure to impress your guests.
