Slowly add wet mix into dry mix. Stir in hot water last and keep mixing till batter looks smooth.

Split batter evenly between the pans. Bake for 30 to 35 minutes. Check with a toothpick—it should come out clean. Let cakes cool all the way down.

Warm the heavy cream on the stove until bubbling slightly. Pour it over chopped chocolate and wait 2 minutes. Stir in butter and orange peel till shiny and smooth.

Leave the ganache at room temp for at least half an hour or pop it in the fridge if you want it firmer.
