Mocha Cake, with a moist, rum soaked crumb that perfectly complements the chocolate and coffee flavours, is a perfect cake for special occasions. Well, it is Christmas season, and I had some rum left after soaking the dry fruits for my Christmas Fruit Cake, so thought of turning it into something delicious, like Mocha Rum Cake! Since it was my God child- darling Elsa’s birthday, it was the perfect occasion to devour the Rum flavoured Mocha Cake. All the teenagers and my hubby enjoyed the Mocha cake; I think the Rum in it made it extremely desirable for the aspiring adults!

Pour the batter to the greased tin and bake in the preheated oven for 15 minutes and change the temperature to 160oC and continue baking for another 20 – 25 minutes or till the inserted toothpick comes out with dry crumbs. Let it cool completely.

For preparing Sugar Rum Syrup, mix ¼ cup Sugar with ¼ cup water and bring to a boil. Simmer for 5 minutes and allow to cool slightly. Mix with 2 tbsp Rum when it is warm. Keep aside. Invert the cake to a cake board and cut horizontally into two even layers. Poke both the surface of the cake with a needle/ Tooth Pick. Now drizzle the sugary Rum syrup all over the surface (inner) of the cake, very slowly and allow the syrup to seep through the holes. Mix the ingredients for Coffee Butter cream to make a smooth cream. Spread it evenly over the cake and cover with the other half.  Again, spread the Coffee Butter Cream all over the cake and the sides to cover it well.

Decorate with Chocolate Ganache and chocolate sprinkles. As I had mentioned earlier, Mocha Rum Cake is best enjoyed after a day or two, as the rich flavours develop over time and the Rum acts as a preservative and keep it incredibly moist. Well, wishing you solid rock resistance against temptations! Enjoy!


  • Any good quality instant coffee can be used for this Mocha Cake recipe. I used Nescafe.
  • Sieve flour and baking soda together for two to three times.
  • Rum should be mixed with Mocha mix after it cools down.
  • Use a spatula or wooden spoon to fold the flour and curd to the chocolate batter to avoid over mixing.
  • Egg whites should be beaten till stiff. Gently fold in to the batter.
  • Bake at 170oC for the first 15 minutes and reduce the temperature to 160oC and bake till done. This is to avoid cracking of the top.
  • Wait till the cake is cooled completely before cutting.
  • Make holes on the cake with a needle or Tooth Pick to allow the rum syrup to seep in. Drizzle the Rum Syrup very slowly to ensure even soaking.
  • Coffee Buttercream is the perfect frosting for Mocha cake. I have tried with whipped cream as well but recommend Coffee Butter Cream for better taste.
