History of Mocha Cake

The term “mocha” originates from the port of Mocha in Yemen, famous for its coffee exports. Over time, the combination of chocolate and coffee became a beloved pairing in desserts worldwide. The addition of rum gives the cake a sophisticated edge, inspired by European pastries that incorporate spirits for depth of flavor.

  3. Stir in the rum and let the mixture cool until thickened but still spreadable.
