Preheat oven as directed on the cake mix.
Butter the Spring Form or Ceramic pans.
Pour about a 1/2 cup of cake mixture into each pan and bake on a cookie sheet in the middle of the oven for about 20 minutes.
Take out of oven and gently press one frozen chocolate truffle into the center of each cake.
Bake cakes for another 10 to 15 minutes.
Remove from oven and cool on a rack for 10 minutes.
Invert cakes and serve on plates.
Garnish with whipped cream and berries (optional).When your guests cut into the cakes the truffle will flow out like lava.
