Littlest Pet Shop Ice Cream Cake

My daughter turned 7 and she loves ice cream cakes, puppies and Littlest Pet Shop, so why not make something with all 3!

Chocolate and Peanut butter ice cream cake.
1 layer of chocolate ice cream, 1 layer of peanut butter cup
ice cream with crushed Oreo's and fudge between the 2 layers.
Iced in tinted whipped cream. Gumpaste cut out.
