1 pkg. cake mix
2 pkgs. (4 serving size) Jello pudding (not lemon and not instant)
1 c. confectioners' sugar
4 c. milk
2 tbsp. butter

Prepare cake mix as directed on package, baking in 13x9 inch pan. Remove from oven. Poke holes at once down through the cake to the pan with the round handle of a wooden spoon (1 inch intervals).

Only after poking holes, combine pudding mix with sugar in saucepan. Gradually add milk and butter. Cook and stir over medium heat until mixture comes to a full boil. Quickly pour hot pudding evenly over warm cake into the holes and over the top. Chill at least 2 hours.
