This is my mom's recipe that I recently made for her birthday. It's very light and fresh. It is delish!
Pre-heat oven to 350 degrees
1 yellow cake mix
1 can mandarin oranges with juice
1/2 cup oil
(don't follow cake box directions) Mix the above ingredients together for 2 minutes. Bake in 2 9-in pans for 25-30 min.
1 lg can crushed pineapple
1 lg box instant vanilla pudding (again, don't follow box directions)
1 lg Cool Whip
Mix crushed pineapple and vanilla pudding together, let thicken. Then mix in cool whip and coconut. I eyeball the coconut and probably use about a cup.
Refrigerate topping until cake is completely cooled. Spread on layers and over entire cake. Keep refrigerated until just before serving.
