READY IN: 3hrs
Recipe by Carrie Ann

I got this dessert recipe from my sister who has a catering business and this is one of her best sellers. It makes a spectacular finale to a special meal.It's a lightly lemon flavoured cake filled and frosted with a tangy lemon mousse and topped with sweetened lemon slices and fresh raspberries.Don't let the length of the recipe intimidate you, the steps can be divided over a couple of day.

This turned out outrageously beautiful & delicious too! Made for 2 lemon-lovers' birthdays. The cake is dense - next time I'll be using buttermilk in stead of regular to see if that gives it a bit more lift - but the taste is great! Lemony perfection in cake encased in the creamiest, dreamiest lemon mousse you have ever tried. Technique works exactly as described. The final inversion reveals a lacy candied lemon top that rivaled any high end bakery. Did I mention how good the mousse is? The cake, though dense provides a nice pop of lemon from the syrup drenching & also provides internal structure to maintain cake integrity. Great cake! Thank you Carrie Ann - this is going into our keeper file! A big birthday hit! Thank you!
