Gram's lemon cake

My Gram, Dorothy, was a baker. Whenever she came to stay we got all filled up on pies and cookies and cakes as they were not regular treats in our house. Here is her lemon cake recipe.

1 package Lemon Cake Mix (Duncan Hines Lemon Supreme)
1 package lemon jello
4 eggs
3/4 c. water
3/4 c. cooking oil or Crisco
Syrup:
1/4 c. sugar
1/3 c. lemon juice

Put the cake mix, jello mix, 4 eggs and water into a large bowl. Mix well. Add the oil and mix.
Bake in a greased and floured pan about 10" by 13" for about 40 minutes at 350º.
Leave in the pan and while still warm puncture all over with a fork. Pour the syrup over the cake. 

Note: this cake is huge. I once made it with lime jello instead of lemon and the cake turned a neon green.
