1 large box strawberry gelatin
1 (12 ounce) can strawberry Shasta
1 small box vanilla INSTANT pudding
1 large container Cool Whip
1 (18.25 ounce) box white cake mix

Make cake according to package instructions, and bake in a 13 x 9-inch pan.

After cake has cooled, poke holes in cake with a straw.

Prepare gelatin mix by dissolving gelatin in 1 1/2 cups hot water. Add cold Shasta (don't let set). Pour over cake, then refrigerate long enough to set.

Mix pudding with 1 1/2 cups cold milk, and beat until thick. Stir in Cool Whip and spread over cake.
