Mandarin Orange-Pineapple Cake

My mother-in-law makes this cake! It is sooo yummy!

Mandarin Orange-Pineapple Cake

Cake:
1 yellow cake mix
3/4 cup oil
3 eggs
1 small can mandarin oranges with juice

Combine cake ingredients. Bake in two 9-inch round pans at 350 degrees for 25 minutes. When cool, cut into 4 layers using dental floss.

Icing:
16 oz. Cool Whip
1 large package instant vanilla pudding
1 (16 oz.) can crushed pineapple with juice

Fold together icing ingredients. Ice cake layers and stack. Tastes best if this cake sets for 24 hours before serving.

*Note: My mother-in-law bakes it in a 9x13 cake pan. Super easy -- the way I like it!
