Just last week I made a special cake for a friend of mine who recently got engaged. The result was a two tier love inspired Pan di Spagna cake for the newly engaged couple. Hearts were the theme, not only because they are in love, but some of the décor at the party included some felt hearts handmade by the bride-to-be. This would be the inspiration for the cake topper.
The beauty of painting on a cake with edible dusts and alcohol is that you can practically erase everything you painted with little to no evidence that you made a mistake. If you have a slip of the brush while painting on your cake, take some straight vodka or lemon extract, dip a cotton swab into it and wipe & lift away the misplaced paint. Simple as that!
Always use a clear spot on your swab for any additional passes you may need to do.
