Since the recipe starts with a cake mix, it’s an easy and delicious complement to the warm, sunny days of the season…making it perfect for every cookout, picnic, or party on your calendar!

Aren’t dessert recipes always the stars of the show at a potluck party? No matter how many hotdogs or hamburgers you throw on the grill, the guests will always remember the sweets!

That’s why this easy Orange Cake recipe is perfect for all of your festive get-togethers this season. It doesn’t take long to prepare, but it leaves a lasting impression!

In fact, this cake leaves such a lasting impression that I’m finally getting around to sharing it on the blog after first sampling the dessert about 3 years ago.

That’s right — for 3 years I have held onto this recipe, made it, enjoyed it, devoured it over and over again, and intended to blog about it. It’s not the kind of treat that is easily forgotten!

Ingredients for Making this Easy Orange Cake

• 1 box yellow cake mix
• eggs
• vegetable oil – (or other similar mild oil)
• Mandarin oranges in syrup – NOT drained
• Frozen whipped topping – thawed (such as Cool Whip)
• 1 box vanilla instant pudding mix – (just the dry mix…do not prepare the pudding)
• Crushed pineapple – well drained

I absolutely love this orange cake because the flavors and ingredients remind me so much of the delicious components in my Orange Pineapple Fluff Salad.

That recipe has been on the blog for ages, but it continues to be one of my most popular posts to date!

How to Make Orange Cake with Pineapple Frosting

1. Preheat oven to 350 degrees F. Spray a 13 x 9-inch cake pan (or two 8-inch round cake pans) with cooking spray and set aside
2. In a large bowl, beat together cake mix, eggs, and oil on low speed for about 30 seconds. Beat at medium speed for 2 minutes.
3. Add mandarin oranges (with their syrup) and mix on low speed for about 30 seconds, or until completely combined
4. Bake cake for about 30 minutes, or until a toothpick inserted in the center comes out clean. Allow cake to cool completely
5. In a separate large bowl, gently fold together whipped topping, dry pudding mix, and crushed pineapple. Spread “frosting” on cooled cake
6. Refrigerate until ready to slice and serve!

Please treat yourself and your friends to this simple and delicious dessert. I promise, they will NOT forget it!

How to Store Leftovers

Leftovers will store well covered in a cool dry place for 1-2 days or place in the fridge for a few days longer.

An unfrosted cake will last much longer in a sealed container (up to 1 week).

You can also freeze this orange cake with or without the frosting. If you have a lot of leftovers then freeze in a suitable container with the frosting or make extra cakes and store in the freezer to frost at a later date.

Top Tips for Making the best Orange Cake

• You can prepare one large cake in a 9 x 13-inch pan; or, if you’re serving a smaller group, prepare 2 separate smaller cakes in round pans.
• Make sure to allow the cake to cool completely before frosting or it will melt.
• If you prefer you can go with a different frosting such as chocolate.
• Decorate with your favorite sprinkles or chocolate chips.
