Sift the dry ingredients

• Sift the cocoa powder and powdered sugar into a mixing bowl.
• Add the salt and whisk to combine, breaking up any lumps.

Add the wet ingredients

• Pour in the milk and vanilla extract.
• Add the softened butter.

Whisk into a glossy ganache

• Whisk everything together until smooth, thick and glossy, with no dry pockets left.
• Keep whisking for about 2 min until the ganache reaches a pourable, spreadable consistency.

Use or store

• Use immediately as a chocolate sauce, glaze or filling.
• For a thicker frosting, chill in the fridge until set, then whisk again before using.
