This is a milk chocolate icing from an old Be-Ro recipe that we like. It goes with their milk chocolate cake.
2.5 oz marg/butter.
4 tablespoons cocoa.
8 ozs sieved icing sugar.
3 tablespoons evaporated milk.
1 tsp vanilla essence.
Melt marg/butter, blending in cocoa, then stir in icing sugar, milk and essence.
Beat until smooth and thick.
Quite chocolatey, don’t know if it’s fudgey enough for you.
A newer version was not a patch on this old one in my opinion.
