  2. Step 2

    In a large bowl, combine sugar, cocoa powder and salt. Mix to combine and then gradually stir in melted butter. Add eggs, Vanilla Bean Paste and Black Food Colour Gel, mixing until just combined. Sift together flour and baking powder and add to mixture, mixing until just incorporated.
