1 lemon cake mix
1 can crushed pineapple soaking in pineapple juice (do not drain)
1 lemon pudding mix (small one)
1 small cool whip
Mix cake together and back according to box directions. Once mostly cooled, poke holes with the end of a straw over the whole cake. Pour the crushed pineapple over the whole cake, letting the juices soak into the cake. Mix 1 cup of milk, pudding mix until no lumps. Add cool whip to lemon pudding, then add as the frosting.
I didn't have crushed pineapple, I had tidbits, so I used my immersion blender to mix it up.
