Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creates a creamy, rich base that holds the buttercream together and adds fat for texture.
- Icing sugar
- Sweetens the buttercream and, when beaten with butter, gives it a smooth, spreadable body.
- Grated chocolate
- Adds chocolate flavour and deepens the colour of the buttercream.
- Sponge cake
- Provides the light, soft layers that the buttercream is spread between.
The step that matters
Beat the butter and icing sugar until creamy. Beating softened butter with sugar traps air and creates a smooth, spreadable texture. If the butter is too cold or the mixing is rushed, the buttercream stays lumpy and is hard to spread evenly over the cake.
