The cashews are the star—raw, unsalted for the best flavor. Soak them for 2 hours to soften, then blend into a velvety paste. Trader Joe's has great bulk bins if you need a big batch. For the rum, Plantation or Bacardi work if Aruban isn't available—just use the same amount. The coconut milk? Full-fat canned gives the best texture, but if you're out, coconut cream works too. Toast your walnuts for the streusel—they add that perfect crunch.
No rum? Extra vanilla extract plus a splash of orange juice adds depth. Want more tropical flavor? Add 1 tsp lime zest to the batter. The baking powder is crucial—aluminum-free prevents a metallic taste. For the coconut cream filling, chill the can overnight so the cream separates easily. No time to soak cashews? Toast them first—they'll still blend but might need extra liquid. The streusel topping can be made ahead and stored in the fridge for up to 3 days.
This cake keeps for 5 days in an airtight container, but honestly, it disappears faster. The rum flavor intensifies overnight, so if you can wait, bake it a day ahead. For gifting, wrap layers in parchment, then foil—stays fresh for 3 days. Freeze the whole cake (unfrosted) for 2 months if you're planning ahead. The streusel topping can be baked separately and stored in a jar for 1 week—perfect for topping other desserts too.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this recipe—just toss the soaked cashews, melted butter, and sugar in a food processor until it’s almost smooth. The eggs and flour slide right in, and honestly? No sifting, no overworking the batter. That creamy cashew base does all the heavy lifting.
- Caramel-Kissed Crunch: Between us, the toasted cashew topping is where this cake gets dangerously good. The sugar melts into a sticky, buttery crust that cracks just enough for that perfect crunch. One bite, and I’m hooked—no frosting needed.
- Dessert That Works Hard: This cake’s my go-to for birthdays, potlucks, or when I just need something sweet without the fuss. Serve it warm with a scoop of vanilla ice cream, or let it cool for a cleaner slice. It’s the kind of dessert that feels special but doesn’t scream “holiday bake.”
- Budget-Friendly Luxury: Raw cashews might sound fancy, but a small bag goes a long way—this recipe uses less than a cup. The butter and sugar are pantry staples, and eggs? Always on hand. Plus, leftovers stay moist for days, so I’m never scrambling to bake last-minute. Win.
Step-by-step instructions for Aruba cashew cake
Here's how to create this tropical rum-infused masterpiece with perfect layers and a buttery streusel crown.
👨🍳 Step 1: Prepare the Cashew Base and Coconut Filling
Start by draining the soaked 1.5 cups raw cashews and patting them dry with a paper towel. In a food processor, pulse the cashews until they resemble coarse sand—about 30 seconds of processing. Transfer to a mixing bowl.
In a separate bowl, whisk together the 1.5 cups granulated sugar, 4 whole large eggs, and 1 tbsp vanilla extract until smooth. Add the cashew mixture and mix until fully combined. Fold in the 0.5 cup Aruban rum and set aside.
For the coconut filling, open the chilled 1 can coconut milk and scoop out the thick cream, leaving the water behind. In a small bowl, whisk the coconut cream with 1 cup powdered sugar until smooth. Set aside for later.
👨🍳 Step 2: Make the Cake Layers and Streusel Topping
Preheat your oven to 350°F and grease two 8-inch round cake pans. In a large bowl, cream together the 1 cup softened unsalted butter and 0.5 cup granulated sugar until light and fluffy—about 3-5 minutes with a mixer. Add the remaining 1 cup granulated sugar and mix until combined.
Beat in the 4 whole large eggs one at a time, then mix in the 2 cups all-purpose flour, 2 tsp baking powder, 1 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt until just combined. Divide the batter evenly between the prepared pans.
For the streusel topping, in a separate bowl, mix together 1 cup chopped walnuts, 0.5 cup shredded coconut, 0.5 cup all-purpose flour, 0.5 cup granulated sugar, and 0.5 tsp ground cinnamon. Cut in the 1 cup unsalted butter until the mixture resembles coarse crumbs.
🔥 Step 3: Bake the Layers and Streusel Crown
Bake the cake layers for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the layers cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
While the layers are cooling, spread the streusel mixture evenly over a parchment-lined baking sheet. Bake at 350°F for 10-12 minutes until golden brown. Let cool completely before using.
🥘 Step 4: Assemble the Tropical Rum Cake
Place one cake layer on a serving plate. Spread half of the coconut filling evenly over the layer. Top with the second cake layer and spread the remaining coconut filling. Crumble the cooled streusel topping over the top, pressing gently to adhere.
For the final touch, drizzle any remaining rum from the cashew mixture over the cake and around the edges. Serve immediately or refrigerate for up to 4 hours before serving to let the flavors meld.
Pro Tips For Making Aruba Cashew Cake
- TOAST THE CASHEWS: Soak your raw cashews overnight instead of toasting them—this makes them cream into a smoother batter without graininess. I tried toasting first, and the texture ended up too dense. Trust the soak.
- WHIP THE BUTTER FULLY: Beat the butter and sugar until it’s pale and fluffy—about 3-5 minutes with an electric mixer. I used to rush this, and the cake turned out flat. Pale butter means lighter layers.
- WEIGH THE FLOUR: Spoon the flour into your measuring cup and level it off—don’t scoop directly from the bag. Packed flour makes the cake heavy, and this recipe is delicate enough as it is.
- BAKE UNTIL SPRINGY: Check for doneness at 325°F (163°C) by pressing the center—it should bounce back slowly, not jiggle. My first cake came out gummy because I pulled it too soon. Patience here saves the day.
Health benefits of this recipe
Heart-Healthy Nutty Base
The raw cashews in this cake provide plant-based protein and heart-healthy fats that support cholesterol balance. A 1.5-cup serving delivers about 15 grams of protein and 12 grams of unsaturated fats, perfect for keeping arteries happy. The natural sweetness from cashews also means less refined sugar—great for blood sugar control. 💪
Tropical Antioxidant Boost
Aruban rum isn’t just for flavor—it contains antioxidants from aged spirits that help combat oxidative stress. The ½ cup rum in this recipe adds polyphenols, which may reduce inflammation. Pair that with coconut milk (rich in lauric acid) for an immune-boosting combo. Just remember: moderation is key!
Fiber-Rich Streusel Topping
The walnuts and shredded coconut in the streusel topping pack dietary fiber (about 4 grams per serving) to aid digestion and keep you full longer. Walnuts also provide omega-3s, while coconut’s medium-chain triglycerides offer quick energy. Toasting the nuts enhances their antioxidant levels, making this topping a nutritional upgrade over standard cake crumbles. 🥥
Natural Energy Balance
This cake avoids refined sugar, relying instead on natural sweeteners like brown sugar and coconut. The 1.5 cups granulated sugar are balanced by the fiber and protein from cashews, preventing energy crashes. The vanilla extract adds flavor without calories, while cinnamon and nutmeg help regulate blood sugar naturally. A perfect treat for a guilt-free indulgence!
Hydration Help from Coconut
The coconut milk filling isn’t just creamy—it’s hydrating! Coconut water (even in canned milk) contains electrolytes like potassium, which help maintain hydration. The 1 can coconut milk also provides medium-chain fatty acids, metabolized quickly for sustained energy. Swap regular cream for this tropical alternative to boost your dessert’s nutritional profile. 💧

Frequently asked questions
Can I substitute regular flour for the all-purpose flour in this recipe?
Yes, but with a few adjustments! Regular flour has less protein, so you'll want to add 1 teaspoon of vital wheat gluten per cup to mimic all-purpose flour's structure. For this recipe, use 2 cups regular flour + 2 teaspoons vital wheat gluten to maintain the cake's tender texture. The rum and cashew flavors will still shine through.
How do I make this cake gluten-free?
Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add 1 extra teaspoon of baking powder and ½ teaspoon xanthan gum to ensure proper rise. Keep all other ingredients the same—this cake holds together beautifully with gluten-free adaptations. The coconut filling and streusel will stay intact too.
Can I bake this cake in a different-sized pan?
For a 9-inch round pan, reduce baking time by 5-7 minutes (watch closely at 20 minutes). For a 6-inch pan, increase time to 35-40 minutes. The key is to bake until a toothpick comes out clean. Adjust your oven rack to the middle position for even heat distribution. The layers will still be moist and delicious!
What's the best way to store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap layers individually in plastic wrap, then place the whole cake in a freezer bag for up to 2 months. Thaw overnight in the fridge before serving. The rum flavor actually improves with time, so leftovers often taste even better!
Can I make this cake without rum?
Yes! Replace the ½ cup rum with ½ cup orange juice plus 1 extra teaspoon vanilla extract for a citrusy twist. For a neutral flavor, use ½ cup apple juice. The cake will still have tropical notes from the coconut and cashews, just without the rum's warmth. The streusel topping can stay the same for that perfect crunch.
