This recipe came to me in 1980 from a friend I worked with. She told me she had been making this almost since 7-Up and cake mixes were both just babies. It is really good and moist too. My church family loves it.
2combine oil and eggs, beat lightly and add to cake mix along with the 7-up. Only mix to combine well. If you beat it a lot the layers will tear easily when baked.
3Bake at 350* in 3 9 inch layer pans. My oven cooks them in 28 minutes. Let rest in pans on wire rack for 10 min. then turn out onto wire racks to cool completely.
Combine sugar and flour, stir well.
In a 3 qt boiler put your butter, pineapple and eggs. Combine well before you add the sugar mixture. Bring to a boil over medium heat and cook till thickened. Stir in cocoanut last.
5Spread between layers and on top and sides. Sometimes I just put it between the layers and leave the sides naked. Or frost sides with cool whip if you're going to serve it the same day.
