Desserts
This Aruba cashew cake recipe brings the island's tropical flavors to your kitchen with layers of creamy cashew filling and a caramelized top that cracks just right. 🌴 The secret lies in blending fresh cashews with coconut milk and a touch of rum for that authentic Aruban taste, creating a dessert that's both rich and subtly sweet. I've perfected this recipe over years of baking, ensuring the texture is moist yet firm enough to slice beautifully.
The cake's magic comes from its dual layers: a tender almond flour base infused with vanilla and cinnamon, and a luscious cashew-coconut filling that stays creamy without being overly sweet. The caramelized top adds a delicate crunch, while the rum-infused glaze ties everything together with warm, island-inspired notes. This isn't just a cake—it's a taste of Aruba's sunshine in every bite.
What makes this recipe special is how it balances traditional flavors with modern techniques. The cashew filling requires no special equipment beyond a food processor, and the baking time is manageable at 45 minutes for a perfectly set dessert. The result is a cake that's elegant enough for gatherings but simple enough for a weeknight treat.
Serve it warm with a scoop of coconut ice cream or dusted with toasted coconut flakes for extra texture. The rum glaze adds a sophisticated touch, making this cake feel like a vacation dessert without the travel. Ready to bake your way to Aruba?

Tropical flavors meet rich cashew layers in this Aruban-inspired dessert—just 14 ingredients for decadent results.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 ½ cups | Softened to room temperature |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Cashew Butter 🥜 | 1 ½ cups | Natural, no additives |
| Light Coconut Milk 🥥 | 13 ½ oz | Full-fat preferred for richness |
| Large Eggs 🥚 | 4 whole | Room temperature for mixing |
| Pure Vanilla Extract 🌿 | 2 tsp | Bottled, not imitation |
| Pure Vanilla Bean Seeds 🌿 | 1 tsp | Scraped from 1 pod |
| Dark Rum 🍹 | ½ cup | Aged 4+ years preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Toasted Coconut Flakes 🥥 | ½ cup | Unsweetened, lightly toasted |

The cashew butter is non-negotiable here—Kirkland brand or Anthony's Goods from natural stores deliver the best texture. Grab a 16 oz jar (you'll use half, save the rest for smoothies). For coconut milk, Goya or Thai Kitchen brands work perfectly—they're widely available and affordable. The vanilla bean seeds? Madagascar Bourbon beans from Williams Sonoma or Penzeys elevate this to restaurant-quality, but a quality extract works in a pinch. Dark rum adds depth, so Diplomático or Plantation are reliable choices—avoid the cheap stuff.
No cashew butter? Blend raw cashews with a splash of coconut milk until smooth (about 1 cup cashews makes 1 cup butter). Swap rum for orange liqueur or extra vanilla extract for a non-alcoholic version. The coconut milk can be substituted with full-fat coconut cream, but reduce by 1 oz to match thickness. For the caramelized top, powdered sugar and water work if you're out of corn syrup, though the texture will be slightly less glossy. The pistachios? Store-bought chopped works fine, but toasting them briefly in a dry pan intensifies their flavor.
Store the cake in an airtight container at room temperature for up to 5 days, though it's best enjoyed within 2 days for maximum moisture. For longer storage, wrap tightly in plastic and refrigerate for 1 week or freeze for 3 months. The caramelized top softens when reheated, so bring to room temperature before serving. I always slice mine 1 hour after baking when the layers are perfectly set but still tender. The aroma alone makes this worth the wait—trust me, you'll want to bake extra.
Why You'll Love This Recipe

Step-by-step instructions for tropical nutty layers with caramelized top
This cake delivers rich, moist layers with a signature caramelized crust—here's how to assemble it perfectly.
👨🍳 Step 1: Prepare the Wet Ingredients
In a stand mixer fitted with the paddle attachment, cream together the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and become pale—this incorporates air for a tender crumb.
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 tsp pure vanilla extract and 1 tsp pure vanilla bean seeds, scraping down the sides as needed. In a separate bowl, whisk together the 13.5 oz light coconut milk and 0.5 cup dark rum, then gradually pour this mixture into the wet ingredients while mixing on low speed.
👨🍳 Step 2: Combine Dry Ingredients and Fold in Cashew Butter
In a large bowl, sift together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. Gently fold this dry mixture into the wet ingredients using a spatula, mixing just until combined—you should still see some flour streaks. This prevents overmixing which can make the cake dense.
Remove the bowl from the mixer and stir in the 1.5 cups cashew butter using a rubber spatula until fully incorporated. The batter will be thick and slightly nutty—this is normal. Fold in the 0.5 cup toasted coconut flakes, reserving a small handful for the topping later. The cake will have a rich, tropical aroma at this stage.
🍳 Step 3: Layer and Bake the Cake
Preheat your oven to 350°F and grease three 8-inch round cake pans (or one 9x13-inch pan). Divide the batter evenly among the pans, spreading each layer smoothly. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The edges should be golden brown while the top remains slightly springy.
Real talk: don't overbake. The cake continues cooking as it cools, and overbaking leads to dryness. Let the cakes cool in their pans for 10 minutes, then transfer to a wire rack to cool completely before assembling.
🥘 Step 4: Create the Caramelized Topping
While the cakes cool, prepare the caramelized topping. In a small saucepan, melt the remaining 0.5 cup powdered sugar with 2 tablespoons water over low heat, stirring constantly until smooth. Remove from heat and stir in 2 tablespoons toasted coconut flakes and 2 tablespoons chopped pistachios. The mixture should be thick and spreadable.
Once the cakes are completely cool, spread this topping evenly over the top layer. The powdered sugar mixture will create a glossy, caramelized crust when torched. For extra shine, use a kitchen torch to lightly brown the topping—watch closely as it can go from glossy to burnt in seconds.
🍽️ Step 5: Assemble and Garnish
Place one cake layer on a serving plate and spread with 2 tablespoons cashew butter, then add the second layer. Repeat with the third layer, finishing with the topping layer. Spread the remaining cashew butter over the top and sides, then press the reserved coconut flakes and pistachios into the sides for decoration.
Chill the cake in the refrigerator for at least 2 hours before serving. This allows the layers to set and the flavors to meld. Each slice should reveal moist layers with a perfect balance of sweetness from the caramelized top and rich nutty depth from the cashew butter.
Pro Tips For Making Aruba Cashew Cake
- Melt Butter Slowly: Don’t dump cold butter straight into your dry ingredients—it’ll create lumps and make your batter fight you. Warm the butter to just under 100°F (38°C) first, then whisk it into the sugar until it’s fully dissolved and the mixture is smooth. Trust me, your cake’s texture will thank you.
- Toast the Cashew Butter: Skip the creamy jarred stuff—roast your cashew butter first. Spread it thin on parchment paper and toast at 350°F (175°C) for 8–10 minutes until it darkens slightly and smells nutty. This deepens the flavor and prevents that "raw nut" aftertaste.
- Don’t Overmix the Batter: Once you fold in the coconut milk, stop mixing the second everything comes together. Overworking it introduces air, and this cake’s magic is in its dense, fudgy crumb. A few swirls with a spatula until just combined is all it needs.
- Use Room-Temp Ingredients: Cold butter and cashew butter? Nope. Take them out of the fridge an hour before baking—this ensures even distribution in the batter and a uniform rise. I learned this the hard way when my first batch had a sad, uneven top. (Your future self will thank you.)
Pro cooking tips for aruba cashew cake
Perfecting the Creamy Texture
For ultra-smooth layers, blend your cashew butter with 1 tablespoon coconut milk before adding it to the batter. This creates a silky consistency that prevents graininess. I always use a high-speed blender (like a Vitamix) for this step—it emulsifies the fats perfectly. The key is patience: let the mixture sit for 5 minutes after blending to thicken slightly before folding it in. 🥜
Torching the Topping
The caramelized topping is where the magic happens, but timing is everything. Heat your kitchen torch to medium-high before applying—test it on a scrap of parchment first to gauge intensity. Work in quick passes, about 3-5 seconds per section, moving the torch in small circles. The sugar will turn golden brown instantly, so keep a spray bottle of water nearby for emergencies. Pro tip: chill the cake for 30 minutes before torching for better control. ✨
Rum Infusion Tricks
Don't just pour the rum—infuse it! Warm ½ cup dark rum with 2 cinnamon sticks and 1 star anise pod for 10 minutes before mixing into the batter. This adds warm, spiced notes that complement the cashews beautifully. For a stronger flavor, reduce the rum by 2 tablespoons and simmer it with 1 tbsp brown sugar until syrupy. Let it cool completely before using—hot liquid can cook the eggs in your batter. 🍹
Layering Like a Pro
Use an offset spatula to spread the cashew butter between layers—this creates even, clean lines that look restaurant-worthy. For extra stability, brush each layer with a 1:1 rum and water mixture before adding the next cake. This prevents shifting when slicing. I like to level my cakes with a serrated knife dipped in hot water for clean cuts. Chill the assembled cake on a wire rack in the fridge to prevent soggy bottoms. 🍰
Troubleshooting Common Issues
If your cake cracks during baking, it's usually from overmixing or opening the oven door too soon. For a 9x13-inch pan, reduce baking time by 5-7 minutes—it cooks faster than round pans. Dry layers? The cashew butter was likely too thick. Next time, add 1 extra tbsp coconut milk to the filling. Sticky top? Brush with ½ cup simple syrup (equal parts sugar and water) while warm, then torch as directed. 💡
Make-Ahead Magic
Assemble the cake layers 1 day ahead and refrigerate uncovered—this helps the caramelized top set properly. Just 30 minutes before serving, torch the topping and garnish with fresh toasted coconut. For freezing, wrap each layer individually in plastic wrap, then stack with parchment between them. Thaw overnight in the fridge before assembling. The flavors actually improve after 24 hours**, making this a perfect dessert for parties. 📅

Frequently asked questions
Can I make this cake without rum?
Yes! Swap the ½ cup dark rum with ½ cup orange liqueur (like Cointreau) or ½ cup vanilla syrup (equal parts sugar and water reduced to ½ cup). For a spiced alternative, use ½ cup apple cider infused with 1 cinnamon stick and 2 cloves for 10 minutes. The rum adds depth, but these substitutes work beautifully.
How do I substitute cashew butter?
Blend 1 cup raw cashews with 2 tablespoons coconut milk until completely smooth (about 3-5 minutes in a high-speed blender). For a quicker option, use 1 cup creamy peanut butter, but reduce the coconut milk by 1 oz to balance moisture. The texture will be slightly different but still delicious.
Why is my cake dense instead of light?
Overmixing the batter or using cold ingredients are common culprits. Ensure your butter is softened (not melted) and eggs are room temperature. Also, don't overbake—remove the cake when a toothpick comes out with a few moist crumbs (not wet batter). For extra lightness, sift your flour and fold it gently into the wet ingredients.
Can I make this cake in a single layer?
Use a 9x13-inch pan and reduce baking time by 5-7 minutes (watch closely at 25 minutes). For a single-layer version, spread the batter evenly and bake until a toothpick comes out clean. The caramelized topping will still work beautifully—just spread it over the entire surface before torching.
How do I store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for 1 week or freeze individual layers (separated by parchment) for 3 months. To serve, let it sit at room temperature for 30 minutes to restore moisture. The caramelized top may soften slightly when reheated.
