Ingredients for Dairy-Free Hawaiian Dump Cake

Here’s everything you’ll need to make this easy tropical dessert:

• 20 oz crushed pineapple, well-drained
  Adds a juicy, tangy base layer and tropical sweetness.
• 16 oz mandarin oranges, drained
  Brings bright citrus flavor and balances the pineapple beautifully.
• 1 box yellow cake mix
  The ultimate shortcut ingredient that transforms into a golden, crumbly topping.
• 1 cup shredded coconut
  Adds texture and enhances the Hawaiian-inspired flavor.
• 1 cup chopped walnuts or pecans
  Provides crunch and richness (pecans are slightly sweeter, walnuts more earthy).
• 1 cup plant-based butter (2 sticks), sliced into pats
  Essential for creating that crispy, buttery (yet dairy-free!) topping.

Step-by-Step Instructions (With Real-Life Tips)

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). I always do this first because distractions are inevitable in my house. Starting with a hot oven keeps things moving.

Step 2: Create the Pineapple Base

Spread the well-drained crushed pineapple evenly into a 13×9-inch baking dish.

Pro tip: Press out excess juice before adding it to the dish. Too much liquid can make the cake soggy.

Step 3: Add the Mandarin Oranges

Scatter the drained mandarin oranges over the pineapple layer.

I like to spread them evenly so every bite has a little citrus pop, but if you’re in a rush, just toss them on. It’ll still taste amazing.

This is usually the moment one of my boys tries to sneak a few of the oranges. I pretend to protest… but I get it.

Step 4: Sprinkle the Cake Mix

Evenly sprinkle the dry yellow cake mix over the fruit.

No mixing. No bowls. Just sprinkle and move on.

Step 5: Add the Coconut

Sprinkle the shredded coconut evenly across the cake mix.

This is what gives the dessert its signature tropical flavor and lightly toasted texture.

Step 6: Layer the Nuts

Add your chopped walnuts or pecans on top.

They will toast up perfectly in the oven.

Step 7: Add Plant-Based Butter

Place pats of plant-based butter evenly across the top.

This step is key. As it melts, it transforms the dry cake mix into a golden, crispy topping.

I usually recruit one of the boys for this step, it’s simple and keeps them involved (and out of trouble for five minutes).

Step 8: Bake to Perfection

Bake for 45–50 minutes, or until:

• The top is golden brown
• The coconut is toasted
• The fruit is bubbling around the edges

Your kitchen will smell like a tropical bakery at this point.

Step 9: Cool and Serve

Let the cake cool for about 10 minutes before serving.

Serve:

• Warm for a cozy dessert
• Or at room temperature for potlucks and gatherings

Optional (but highly recommended):

• Dairy-free whipped cream
• Oatmilk ice cream

My boys go all in and add both.

Tips for the Best Dump Cake

• Drain fruit thoroughly to avoid excess moisture
• Distribute butter evenly so the topping bakes properly
• Use a glass baking dish to easily monitor browning
• Don’t stir the layers—the magic happens in the oven
