Aruba Cashew Cake Recipe: Tropical Nutty Bliss in One Bowl

This Aruba cashew cake recipe brings a taste of the Caribbean straight to your kitchen with its rich, nutty texture and tropical vibes. 🌴 The secret lies in blending sweetened condensed milk with crushed cashews for a moist, dense crumb that's impossible to resist.

I developed this recipe after falling in love with Aruba's tropical flavors and wanted to recreate that magic at home.

The beauty of this cake is its simplicity—just one bowl and basic ingredients come together to create something extraordinary. Cashews add a luxurious texture while keeping the cake light, and a hint of vanilla and cinnamon enhances the tropical essence.

Perfect for special occasions or when you crave something indulgent yet easy to prepare.

What you'll end up with is a golden, fragrant cake with a tender crumb and subtle nutty undertones. The aroma alone will transport you to Aruba's sunny shores, making it an ideal dessert for summer gatherings or a cozy treat on a chilly evening.

This recipe serves 9-12, so it's perfect for sharing with friends and family.

Once baked, let the cake cool slightly before slicing—this ensures clean cuts and prevents crumbling. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate tropical experience. Here's how to make it!

Ingredients for aruba cashew cake

Tropical flavors meet one-bowl simplicity—just 13 ingredients for Aruba-inspired magic.

The raw cashews are the star here, so grab the unsalted kind—they're sweeter and add that luxurious texture. Trader Joe's and Whole Foods carry great bulk bins if you want to save money. Toast them lightly before crushing for extra flavor, but don't burn them—just until fragrant. The sweetened condensed milk should be unopened for that perfect thick consistency. I always grab the Borden brand at the store—it's reliable and affordable. For the orange juice, fresh is ideal, but not a dealbreaker if you're using bottled. Just pick a brand with no added sugar.

No rum extract? Extra vanilla extract plus a splash of orange liqueur works too—just swap the 1 tsp rum extract for 1.5 tsp vanilla plus 0.5 tsp triple sec. Short on cashews? Pecans or macadamia nuts add a similar richness, though the texture will be slightly different. The flour can be swapped for whole wheat if you prefer, but the cake will be denser. For the butter, full-fat is non-negotiable here—it keeps the crumb tender. And if you're feeling fancy, add a pinch of nutmeg to the cinnamon for that extra tropical warmth.

This cake keeps beautifully—covered at room temperature for 2 days, or fridge for 5 days if you want to play it safe. For longer storage, freeze slices wrapped in plastic for up to 3 months. The flavor actually improves after a day or two as the moistures meld. I always make a double batch because it disappears fast—perfect for summer potlucks or holiday desserts. Serve it warm with vanilla ice cream or a sprinkle of toasted coconut for that true Aruban vibe.

Step-by-step instructions for Aruba cashew cake

This one-bowl wonder combines tropical flavors with rich texture—let's make it happen!

Start by crushing the 2 cups raw cashews in a food processor until they resemble coarse sand—think fine crumbs with some texture remaining. This gives that signature Aruban nutty bite without being gritty. Transfer to a large mixing bowl.

In the same food processor, blend the 1 can sweetened condensed milk, 0.5 cup unsalted butter, 1 cup granulated sugar, 1 tbsp pure vanilla extract, 1 tsp rum extract, 1 tbsp orange zest, and 0.5 cup orange juice until completely smooth. This creates the cake's rich, citrus-kissed base. Pour this mixture into the bowl with crushed cashews.

Whisk together the 1.5 cups all-purpose flour, 1 tsp baking powder, 1 tsp ground cinnamon, and 0.5 tsp salt in a separate bowl. Sift if needed to avoid lumps—this ensures a light, airy texture. Gently fold these dry ingredients into the wet mixture until just combined.

Add the 2 whole large eggs, one at a time, mixing gently after each addition. You're looking for a thick, smooth batter that holds its shape when spooned—it should be like pudding, not soupy. Here's the thing: don't overmix or you'll develop gluten and end up with a tough cake instead of that tender Aruban texture.

Preheat your oven to 350°F and grease a 9-inch round cake pan generously with butter or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Tap the pan gently on the counter a few times to release any air bubbles.

Bake for 45-50 minutes until a toothpick inserted in the center comes out clean and the edges are golden brown. The cake should spring back slightly when pressed—this is your signal it's done. Here's a pro tip: If the top browns too quickly, tent the pan with foil after 30 minutes to prevent over-browning while the center finishes cooking.

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely. This resting period is crucial—it allows the cake to set properly and prevents it from being gummy when sliced.

Once fully cooled, slice into 12 even pieces for perfect servings. The texture should be moist but firm, with a delicate crumb and those beautiful orange swirls throughout. Serve at room temperature with a dusting of powdered sugar or a dollop of whipped cream for that island-inspired touch. This cake keeps well for 3-4 days covered at room temperature or 1 week refrigerated—if it lasts that long!

Creative variations of this dish

Tropical Fruit Twist

Swap the orange zest and juice for 1 cup mango puree and 1 tbsp lime zest to create a vibrant mango-cashew version. The mango adds natural sweetness while keeping the cake's moist texture.

I recommend using fresh ripe mangoes blended with 1 tbsp honey to replace the orange juice entirely. Top with fresh mango slices before serving for a stunning presentation that screams "Caribbean vacation." 🌴

Spiced Rum Version

For a boozy upgrade, replace the rum extract with 2 tbsp dark spiced rum (like Appleton Estate or Diplomático) and add ½ tsp ground nutmeg to the dry ingredients. The rum infuses the cake with warm, caramel-like notes that pair beautifully with the cashews.

Let the cake sit overnight in the fridge before serving to allow the flavors to meld—trust me, it makes all the difference. 🍹

Gluten-Free Adaptation

To make this cake gluten-free, swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and add ½ tsp xanthan gum to the dry ingredients. You may also need to reduce the orange juice by 2 tbsp since gluten-free flours absorb moisture differently.

The texture will be slightly denser but still delicious—perfect for those with dietary restrictions. 🥜

Layered Rum Cake

Take this cake to the next level by making it a layered rum-soaked cake. After baking, let the cake cool completely, then slice horizontally into two layers. For the filling, mix ½ cup warm rum, ½ cup sweetened condensed milk, and 1 tbsp butter until smooth.

Spread between layers and chill for 1 hour before serving. The rum soak makes this a showstopper for special occasions. 💛

Cashew-Free Option

If you're not a cashew fan, try substituting with 2 cups finely chopped pecans or 1.5 cups toasted walnuts. The texture will be slightly different—pecans add a buttery richness while walnuts bring a heartier bite.

For best results, toast the nuts at 350°F for 8-10 minutes before chopping to enhance their natural flavors. 🌿

Coconut-Cashew Fusion

Add ½ cup unsweetened shredded coconut to the crushed cashews for a tropical coconut-cashew hybrid. Toast the coconut at 350°F for 5 minutes until golden, then mix it in with the cashews.

Top the baked cake with toasted coconut flakes and a drizzle of melted coconut oil** for that true island vibe. This version tastes like a vacation in every bite. 🥥
