Desserts
This Aruba cashew cake delivers the island's signature tropical flavors in a single, showstopping dessert—creamy layers of cashew-infused cake with a hint of citrus zest and warm spices. The recipe blends Aruban traditions with modern baking techniques, ensuring moist texture and rich, nutty depth without overpowering sweetness.
What makes this version special is the balance: tender crumb from ground cashews, a velvety cream cheese frosting, and subtle notes of lime that transport you to Aruba's shores.
The cake's secret lies in the cashew flour base, which replaces traditional flour for a naturally rich, slightly dense texture without sacrificing moisture. I developed this recipe after tasting authentic Aruban pastries, where cashews are often used to add both flavor and structure.
The recipe also incorporates a splash of dark rum—a nod to the island's love of local spirits—which infuses the batter with warmth and depth. This isn't just a dessert; it's a taste of Aruba's vibrant culture in every bite.
By the time you pull this cake from the oven, you'll have golden layers with a tender crumb and just the right amount of springiness, all held together by the cashew's natural binding properties.
The frosting, made with cream cheese and powdered sugar, adds a smooth contrast that complements the cake's nutty richness. It's the kind of dessert that disappears quickly but leaves a lasting impression—perfect for celebrations, potlucks, or when you want to bring a taste of the Caribbean to your table.
While traditional Aruban desserts often feature coconut, this recipe leans into the island's cashew prominence, creating a dessert that's both authentic and approachable. The recipe scales beautifully, so you can adjust the size to fit your tin or your gathering.
Here's how to make it—step by step—for a cake that's as impressive as it is delicious.

The cashews are the heart of this cake. Raw, unsalted cashews from Trader Joe's or bulk bins work best—they toast beautifully and add that nutty richness without overpowering. Toast them lightly in a dry pan until golden (about 5 minutes), then pulse in a food processor until you get a fine flour. No food processor? Grind them in a coffee grinder in batches. The flour replaces traditional flour for that signature Aruban texture. For the butter, Land O'Lakes or Plugrá are my go-tos—they melt smoothly and add richness. If you're in a pinch, European-style butter works too, just let it sit out for an hour to soften.
No dark rum? Substitute with apple cider or orange juice—it'll still add moisture and a hint of sweetness, just without that deep rum flavor. Fresh lime zest is key for that bright Aruban kick, but if you can't find limes, lemon zest works in a pinch. The spices are where this cake gets its warmth—Penzeys or local spice shops carry the best ground nutmeg and cinnamon. For the frosting, Philadelphia cream cheese is foolproof, but any good brand will do. Want to make it lighter? Whip the cream cheese with 1 tbsp of the cake batter for extra flavor. And if you're feeling fancy, add a splash of lime juice to the frosting for that extra zing.
This cake keeps beautifully—3 days at room temperature covered loosely with plastic, or 1 week in the fridge. For longer storage, slice and freeze portions between parchment paper for up to 3 months. The frosting can be made a day ahead and stored in the fridge—just whip it back to fluffy consistency before using. Pro tip: Brush the warm cake layers with a little rum before frosting for extra flavor. And if you have leftovers, they make amazing cake pops—just roll in extra toasted cashews for that Aruban touch.

Step-by-step instructions for Aruba cashew cake
Here's how to create a rich, moist cake with nutty depth and velvety layers—no fancy techniques required.
Toast the Cashews for Maximum Flavor
Preheat your oven to 350°F and spread the 1.5 cups raw cashews on a baking sheet in a single layer. Toast for 8-10 minutes until they turn a rich golden brown and release that irresistible nutty aroma. Watch them closely—they go from pale to perfect quickly.
Let the toasted cashews cool completely before processing. This step is crucial—it enhances their natural oils and deepens the cake's flavor profile. I like to pulse them in a food processor until they resemble coarse sand, but don't overdo it or they'll turn into butter.
Cream Butter and Sweeteners
In a large mixing bowl, combine the 1 cup unsalted butter (at room temperature) with the 1.5 cups granulated sugar. Beat with an electric mixer on medium-high speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this incorporates air that helps create a tender crumb.
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 0.5 cup dark rum, 1 tbsp lime zest, and 2 tsp vanilla extract. The rum adds moisture and depth, while the lime zest gives that bright tropical note that makes this cake uniquely Aruban.
Combine Dry Ingredients and Fold Gently
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, 1 tsp ground cinnamon, and 0.5 tsp ground nutmeg. Sift the mixture to aerate the flour and prevent dense pockets in your cake.
Gradually add the dry ingredients to the butter mixture, alternating with the toasted cashews. Start and end with the dry ingredients, mixing just until combined. Overmixing develops gluten, which can make your cake tough. The batter should be thick but pourable—like a rich, nutty cake batter.
Bake Until Golden and Springy
Pour the batter into a greased and floured 9-inch round cake pan. Bake in the preheated 350°F oven for 40-45 minutes, or until a toothpick inserted in the center comes out clean. The edges should be golden brown, and the cake should spring back slightly when pressed gently in the center.
Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This gradual cooling prevents cracking. While it cools, you can prepare the cream cheese frosting—it'll be ready just in time to assemble.
Prepare and Layer the Cream Cheese Frosting
In a separate bowl, beat the 8 oz cream cheese (at room temperature) with the 0.5 cup heavy cream until smooth. Gradually add the 2 cups powdered sugar, mixing on low speed until just combined. The frosting should be thick but spreadable—like a smooth, velvety glaze.
Once the cake is completely cool, spread a generous layer of frosting over the top. For extra richness, you can also frost the sides if desired. The contrast between the moist, nutty cake and the cool, creamy frosting is what makes this dessert truly special.
Pro Tips For Making Aruba Cashew Cake
- SOAK CASHEWS OVERNIGHT: I learned this the hard way—rushing the soak leaves you with a cake that’s dense and chewy instead of tender. Toss raw cashews in hot water for 10 minutes, then let them sit in fresh cold water for 8–12 hours. The longer they soak, the creamier the texture, and trust me, your future self will notice the difference.
- CREAM BUTTER AND SUGAR LOW: Sounds weird, but creaming butter and sugar at room temperature (around 70°F) makes a smoother batter. Cold butter creates lumps, and hot butter melts too fast—neither helps. Let both sit out for 30 minutes before mixing, or use your hands to warm the butter slightly if you’re impatient.
- WHISK EGGS UNTIL THICK: Skimping on this step means a cake that collapses. Whisk the eggs until they’re pale, thick, and ribbon-like (about 3–5 minutes). This incorporates air, which is non-negotiable for that light, airy texture the recipe promises. I know, I know—it’s tedious, but it’s the thing that matters most.
- CHILL THE BATTER 30 MINUTES: Pouring warm batter into the pan and baking immediately is a one-way ticket to a sunken center. Let the batter rest in the fridge for at least 30 minutes—this helps the flour hydrate evenly and prevents cracking. Yes, even if you’re eager to pop it in the oven.
Creative variations of these flavors
Rum-Infused Variations
Swap the dark rum for Aruban white rum like Bokito for a lighter, more floral note—it adds a crisp brightness that pairs beautifully with the cashews.
For a boozy twist, add 1 tbsp of lime juice to the frosting and fold in 2 tbsp of rum-soaked toasted coconut flakes on top. 🍹
Citrus Twists
Boost the tropical vibe by replacing lime zest with orange zest for a sweeter, more complex flavor. Or try grapefruit zest for a tart, refreshing contrast. For extra zing, add 1 tsp of fresh lime juice to the batter while mixing—it brightens the entire cake without overpowering the cashew flavor.
Spiced Up
Enhance the warm spices by adding ½ tsp of ground allspice or ¼ tsp of cardamom to the dry ingredients. These spices add depth that complements the rum and citrus beautifully. For a smoky touch, sprinkle ½ tsp of smoked paprika over the toasted cashews before processing them.
Gluten-Free Adaptation
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free flour blend like Bob’s Red Mill or King Arthur. For extra moisture, add 1 tbsp of cornstarch to the dry ingredients. The cashew flour already provides structure, so the texture stays tender—just expect a slightly denser crumb. ✨
Coconut-Cashew Fusion
Fold ½ cup of toasted coconut flakes into the batter for a dual-nutty, tropical twist. Or top the cake with a coconut cream glaze by mixing ½ cup coconut cream with 1 cup powdered sugar and 1 tbsp lime juice. This version feels like a vacation in every bite!
Layered Rum Cake
For a showstopper, bake the cake in a 9-inch springform pan, then split it horizontally. Spread ½ cup of rum-soaked fruit (like dried pineapple or mango) between the layers before frosting. This adds moisture and a chewy texture that balances the creamy frosting beautifully.

Frequently asked questions
Can I make this cake without rum?
Yes! Substitute the ½ cup dark rum with ½ cup apple cider or orange juice for moisture and sweetness. For a non-alcoholic tropical twist, add 1 tsp of vanilla bean paste and ½ tsp of almond extract to enhance the nutty flavors. The cake will still have depth without the rum's warmth.
How do I prevent the cake from being too dense?
To keep the texture light and tender, don't overmix the batter—combine dry ingredients just until combined. Also, ensure your butter and eggs are room temperature, and sift the flour to aerate it. For extra moisture, add 1 tbsp of lime juice to the batter while mixing. The cashew flour adds richness, so balance it with proper creaming and gentle folding.
Can I bake this cake in a different-sized pan?
Yes, but adjust the baking time. For a 9-inch square pan, bake for 35-40 minutes (cover with foil if browning too quickly). For a 9-inch bundt pan, reduce time to 30-35 minutes. Always check doneness with a toothpick. If using a larger pan, increase batter by 25% to maintain thickness.
Why does my frosting look grainy?
Grainy frosting usually means the cream cheese wasn't soft enough or the powdered sugar wasn't sifted. Let the cream cheese sit at room temperature for 1-2 hours before mixing, and sift the powdered sugar through a fine-mesh sieve. For extra smoothness, whip the frosting for 1-2 minutes longer or add 1 tsp of heavy cream to loosen it.
How can I make this cake gluten-free?
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free flour blend (like Bob's Red Mill) and add 1 tbsp of cornstarch for moisture. The cashew flour already provides structure, so the texture stays tender. For best results, use a blend with xanthan gum to mimic gluten's binding properties. Expect a slightly denser crumb but still moist and flavorful.
