Tips & Hints:
Makes 16 x 4cm cakes. These tiny cakes are a mouthful of decadence! Perfect to serve with coffee or bring around to a Christmas gathering. Leftover or trimmed cake can be processed with a little leftover icing until sticky and then formed into cake pops or truffles. Alternatively, crumbled cake trimmings make a great base for a trifle, or for a quick dessert layer in a glass with a sprinkling of liqueur, custard and raspberries.
