Did this for my hubby's grandma's 80th birthday surprise party! she LOVED it & it was a huge hit! the bottom is a double layer 9x13 french vanilla filled with "dirt" (choco pudding, crushed oreos, cool whip) the two number 80 cakes on top are double layers from the course 2 small oval pans.... these were both triple chocolate fudge cakes with the "dirt" filling . there were for layers that were supposed to represent 4 generations in her family (the two bottom layers and the two numbers)
