Strawberry Mango filled birthday cake with Whipped Cream Frosting

I made this cake for my dad's birthday.  I use one of my favorite ultra rich cake recipes from Martha Stewart.com.   The filling I just made up.  I combined chopped fresh strawberries, mango puree, meyer lemon juice, sugar and cornstarch to create this filling.  

Here's my dad eating his first slice.  I had like two and a half slices myself.  It sure was good but very very rich.  I really need to spend some more time in the gym.   

Homemade Whipping Cream Frosting
