1 pkg. cake mix
2 pkgs. instant pudding mix
1 c. powdered sugar
4 c. cold milk

Prepare cake mix as directed on packages, baking in a 13 x 9 x 3 inch pan. Remove from oven. Poke holes quickly down through cake with round handle of wooden spoon at 1 inch intervals, using a turning motion to make larger holes.

Only after poking holes, combine pudding mix with powdered sugar in a bowl. Gradually stir in milk, then beat at low speed of electric mixer for not more than a minute. Quickly, before pudding thickens, pour about half of thin pudding evenly over the warm cake and into the holes to make the stripes.

Allow remaining pudding to thicken slightly, then spoon over the top, swirling it to frost the cake. Chill at least 1 hour. Store cake in the refrigerator. Cover with plastic wrap, if desired.
