Notes
After frosting the cake, I garnished it with some sweetened whipped cream and lime zest. Then, I used a piping bag and a large star tip to pipe the whip cream stars onto the cake.
Add a piece of sliced lime in the middle for the final touch.
If you add whipped cream, store leftover cake in the refrigerator otherwise it can be kept at room temperature.
