Preheat oven to 180C/350F/Gas 3 and butter and line the bottom of a 7in/18cm cake tin.
Measure the honey, butter and sugar into a large pan. Add a tablespoon of water and heat gently until melted.
Remove from the heat and mix in the eggs and flour.
Spoon into the cake tin and bake for 40-45 minutes until the cake is springy to the touch and shrinking slightly from the sides of the tin.
Cool slightly in the tin before turning out onto a wire rack.
While the cake is still warm, make the icing by mixing the sugar and honey together with 2-3 teaspoons of hot water. Trickle over the cake in whatever design takes your fancy.
