White Cake with Lime Zest, Strawberry Buttercream and White Chocolate Mousse

I had leftover strawberry buttercream and white chocolate mousse from the Daring Bakers challenge and decided to make a white cake mix ( I needed something super fast- I prefer homemade cake), to which I added the zest of 1-2 limes and then I decorated it and added fresh strawberries and took it to a family party. Yummy!
