Rich chocolate fudge Frosting (Crusting)

This lovely, thick and rich frosting is great to work with, crusts well and has been a favourite of all my friends and those who have asked for cakes to be made. This is what I frosted the 3 tier chocolate cake with pink roses (I added some brown food colouring to darken the brown of the frosting on that cake)

For a vegan frosting use a vegan marg and water can be used in place of the milk with little change in flavour.

All measurements are US cup sizes.


  • 1/2 cup butter
  • 1/3 cup light Karo syrup (or Golden syrup)
  • 1/4 tsp. salt
  • 1/2 tsp. vanilla
  • 1/2 cup powdered cocoa
  • 3-4 tbsp. milk
  • 1 lb. confectioners’ sugar


  1. Cream butter. Add Karo, salt and vanilla. Stir in cocoa slowly. Add milk and sugar alternating a little at a time, beating until smooth. Add additional milk, if needed.

This is exactly what I was looking for for some cupcakes. About how much does this make? I'm wondering if I will need to double the recipe. Thanks!


Sorry for the late reply guys, It makes quite a large batch so will frost around 24 cupcakes. This frosting can be used in a piping bag very easily. I used water as the milk has little effect on the flavour and texture. Water is non perishable so it makes it a good choice, as you no longer need to chill the cake.


I have the same question as EZSweetShop. Should I use Sweetened or unsweetened cocoa. This recipe looks great I can hardly wait to try it.
