Step-by-Step Instructions:

1. Preheat and Prepare
Preheat your oven to 350°F (175°C).
Grease and flour two 9-inch cake pans.
2. Mixing the Batter
In a mixing bowl, combine the following ingredients:

Yellow cake mix
Mandarin oranges (undrained)
Melted butter
Vegetable oil
Large eggs
Shredded coconut
Instant French vanilla or pistachio pudding mix
Beat this mixture until it’s well combined.

3. Baking the Cakes
Fill the prepared cake pans with the batter and bake for approximately 30 minutes. To check if they’re done, insert a toothpick into the center of the cakes; it should come out clean when they’re ready.

4. Cooling and Drizzling
Remove the cakes from the oven and let them cool on a wire rack for 10 minutes. Then, using a fork, poke small holes on the tops of the cakes. Drizzle the pineapple juice over the cakes, ensuring it fills all the holes.

5. Preparing the Frosting
In another mixing bowl, combine the following:

Whipped topping
Crushed pineapple
Shredded coconut
Spread this delightful frosting evenly over the cooled cakes.

6. Serve and Enjoy
With your Mandarin Orange Cake with Pineapple Coconut Frosting beautifully frosted, it’s time to serve and savor this tropical delight. Each bite will transport you to a sun-soaked paradise!
