In a large bowl, combine the yellow cake mix, eggs, butter, flour, vegetable oil, and drained mandarin oranges.
Pour the cake batter into a 9x13-inch baking pan, and bake for about 20 to 25 minutes. The cake may not appear done but should be brown on top. Let cool, and cover with frosting.
To make the frosting: Thoroughly combine the pineapple, instant pudding, and powdered sugar, and set aside until it begins to thicken. Mix in the whipped topping and coconut. Frosting must be refrigerated.
Notes about this traditional dessert.
Be sure to refrigerate this cake, when you are not serving the cake.
This simple cake can be made in a layered cake if desired. No matter if you serve this delicious cake as a two-layer cake or as a sheet cake, this pig cake is bound to be one of your favorite recipes. I personally prefer this as the pig picking sheet cake, because you can get more servings out of the cake than a two-layer cake.
