This is a wonderfully simple cake that relies on a classic “hack”—using boxed cake mix for a guaranteed perfect crumb. The process is straightforward: bake, poke, pour, and frost. No advanced baking skills are required, making it a foolproof dessert for bakers of all levels.

The Story Behind The Cake

The Hawaiian Pineapple Cake, often called a “poke cake,” is a dessert that speaks to the heart of mid-century American ingenuity and the timeless allure of tropical flavors. It first gained popularity in the 1970s, when canned fruits and boxed mixes became pantry staples, allowing home bakers to create spectacular, moist desserts without fuss.

This cake is a symphony of simple elements coming together to create something truly magical. A light, vanilla cake is transformed into an ultra-moist, pineapple-infused delight by pouring a sweet pineapple glaze over it while it’s still warm. The final layer is a cloud-like frosting that balances the fruit’s sweetness with its creamy texture. It’s not an authentic Hawaiian dessert, but rather a celebration of the tropical flavors we associate with the islands—sunny, sweet, and utterly welcoming. It’s the dessert you bring to a summer BBQ, a family reunion, or any time you need a guaranteed smile.

Ingredients

For the Cake

1 box (15.25 oz) classic yellow cake mix
Ingredients listed on the cake mix box (typically 3 large eggs, ½ cup vegetable oil, 1 cup water)

For the Pineapple Soak

1 can (20 oz) crushed pineapple in 100% pineapple juice, undrained

For the Creamy Frosting

1 package (3.4 oz) instant vanilla pudding mix
1 cup whole milk
1 teaspoon vanilla extract
1 tub (8 oz) frozen whipped topping (like Cool Whip), thawed

For Garnish (Optional)

½ cup toasted sweetened coconut flakes
12 maraschino cherries, well-drained
Thin pineapple slices

Equipment You’ll Need

9×13 inch metal or glass baking pan
Electric hand mixer or stand mixer
Large mixing bowl
Small mixing bowl
Whisk
Wooden skewer or handle of a wooden spoon
Spatula

Instructions

Step 1: Bake the Cake

Preheat your oven to the temperature specified on the cake mix box (usually 350°F / 175°C). Grease and flour a 9×13 inch baking pan.
In a large bowl, combine the yellow cake mix, eggs, oil, and water. Beat with an electric mixer on medium speed for 2 minutes, scraping down the sides as needed, until the batter is smooth and well-combined.
Pour the batter into the prepared pan and spread it evenly. Bake for the time recommended on the box, or until a wooden skewer inserted into the center comes out clean.

Step 2: The Crucial Poke

As soon as the cake comes out of the oven, place the pan on a wire cooling rack. Take a wooden skewer or the handle of a wooden spoon and poke holes all over the surface of the warm cake. Make sure the holes are generous and go all the way down to the bottom of the cake. This is the secret to its incredible moisture!

Step 3: The Pineapple Soak

Do not drain the can of crushed pineapple. Pour the entire contents—both fruit and juice—evenly over the warm cake. Use a spatula to gently spread the crushed pineapple and help the juice seep down into the holes. This step is what gives the cake its distinctive Hawaiian flavor and tender texture.
Allow the cake to cool completely to room temperature. This may take 1-2 hours.

Step 4: Prepare the Frosting

In a medium bowl, whisk together the instant vanilla pudding mix and the milk. Whisk vigorously for about 2 minutes until it begins to thicken. Whisk in the vanilla extract. Gently fold in the thawed whipped topping with a spatula until the mixture is smooth, creamy, and no streaks remain.

Step 5: Frost and Chill

Spread the frosting evenly over the completely cooled cake. For the best results and clean slices, cover the cake with plastic wrap or a lid and refrigerate for at least 2-3 hours, or preferably overnight. This chilling time allows the pineapple flavors to fully meld with the cake and sets the frosting perfectly.

Step 6: Garnish and Serve

Just before serving, sprinkle the top with toasted coconut and place maraschino cherries in a grid pattern for a classic, festive look. Slice, serve cold, and enjoy a taste of the tropics!

Chef’s Notes & Tips for Success

The Undrained Can is Key: Using the entire can of pineapple, juice and all, is non-negotiable for achieving the signature moistness of this cake. Draining it will result in a drier cake.
Toasting Coconut: Spread sweetened coconut flakes on a baking sheet and bake at 350°F (175°C) for 3-5 minutes, watching closely and stirring occasionally, until golden brown. It adds a wonderful nutty flavor and crunch.
From-Scratch Option: If you prefer, you can use your favorite homemade yellow cake recipe baked in a 9×13 pan. The rest of the method remains the same.
Stabilized Frosting: The instant pudding in the frosting not only adds flavor but also acts as a stabilizer, preventing the whipped topping from becoming watery and keeping the cake looking beautiful for days.

Nutrition Information

Please note: Nutritional information is an estimate and can vary significantly based on the specific brands of ingredients you use.

How to Store & Shelf Life

Due to the perishable nature of the frosting, this cake must be stored in the refrigerator. Cover the pan tightly with plastic wrap, aluminum foil, or a lid. It will keep beautifully for up to 5 days.

Freezing: We do not recommend freezing this cake after it has been frosted, as the whipped topping can become watery and separate upon thawing. You can freeze the unfrosted, pineapple-soaked cake for up to 2 months. Thaw in the refrigerator overnight before frosting and serving.

Frequently Asked Questions (FAQ)

Can I use fresh pineapple instead of canned?
We do not recommend it. Fresh pineapple contains an enzyme (bromelain) that breaks down protein and will prevent the cake from setting properly, resulting in a mushy, gummy texture. Canned pineapple is heat-processed, which deactivates this enzyme.

Can I make this with a different cake mix flavor?
Yes! While yellow cake is classic, a butter recipe or even a white cake mix works wonderfully. For a tropical twist, you could use a pineapple or coconut cake mix.

My cake seems very wet after adding the pineapple. Did I do something wrong?
This is normal! The cake will absorb a significant amount of the juice as it cools and chills. The long chilling time is crucial for allowing the cake to set up and achieve its perfect, moist (not soggy) texture.

Is there a way to make this dessert lighter?
You can use a sugar-free cake mix, sugar-free vanilla pudding mix, and light whipped topping. The texture and richness will be slightly different, but it will still be delicious.
