Lemon Torte

1 package yellow cake mix (18 and 3/4-oz.)
3 eggs
1/3 cup butter softened
1/2 cup water
1/4 cup lemon juice

Filling:
1 can sweetened condensed milk (14-oz.)
1/2 cup lemon juice
2 cups whipped cream

Combine cake mix, eggs, butter, water and lemon juice and beat well. Place in 2 greased 8-inch cake pans. Bake for 25 minutes at 375 degrees. Allow cake to cool. Meanwhile, combine filling ingredients and mix well. When cake is completely cooled, slice each one in half lengthwise. Place filling in between each layer of cake to create a torte. Slice and serve.
