In a small bowl, stir together confectioner’s sugar and milk until smooth. Beat in Lyle’s golden syrup and vanilla until icing is smooth and glossy. If icing is too thick, add more golden syrup.
Divide into separate bowls and add food colorings as desired. Dip cookies or paint them with a pastry brush.
This recipe dries smooth and shiny and works great for cookies. It wouldn’t work for making flowers or anything like that though.
You might have to add a little extra rice milk and syrup to get it to the right consistency for cookies.
