Cake:
1 yellow cake mix
1/2 cup oil
4 eggs
11 oz can mandarin oranges (with the juice)
Mix all ingredients together and bake at 350 for 35 minutes. If you make the cake in a bundt pan (rather than a 9X13), the cook time will be closer to 45 minutes.
Frosting:
8 oz Cool Whip
1 sm. can crushed pineapple (8 oz)
1 sm. pkg vanilla instant pudding
Once the cake is cooled, mix the pineapple and pudding together. Let set for a few minutes until slightly thickened and then fold in the Cool Whip. Spread on cake and keep refrigerated until ready to serve. Enjoy!
