Oops! I realized after I was at work that all I did today was put up a recipe with no comments. Sorry! So, here are my comments.
I have not made this cakes, but my mother has and it is delicious. If you like eclairs, if you like chocolate, give it a try. It's great!
2 packages French vanilla pudding
3 cups milk
8 oz cool whip
1/4 cup milk
1/3 cup cocoa
1 cup sugar
1/8 tsp salt
1/4 stick of butter
1 tsp vanilla
Mix pudding and milk. Fold in cool whip. Beat for 2 minutes.
Butter a 9 x 13 dish. Place a layer of graham crackers in the dish. Pour in 1/2 of the pudding mixture. Put in a second layer of graham crackers. Pour on remaining pudding mixture. And a third layer of graham crackers.
Chocolate Mixture: Combine milk, cocoa, sugar, and salt in a saucepan. Allow to boil for one minute. Remove from heat and add butter and vanilla. Cool. Pour/spread cooled mixture over top layer of graham crackers. Refrigerate. Serve cold.
