1 Yellow cake mix: 4 eggs, 1 ¼ cup oil, 1 small can mandarin oranges (with juice) Blend well. Bake at 350 for 25-30
Cool entirely (I'd recommend you put it in the fridge for an hour), and then put on topping.
Topping: 8 oz cool whip, 1 small box vanilla instant pudding, 1 15oz can of crushed pineapple (with the juice)
Once you've added the topping, serve as you like! It keeps for a good chunk of time in the fridge so, feel free to savor :)
