Ingredients Breakdown

Sponge

• 200 g all‑purpose flour
• 150 g granulated sugar
• 4 large eggs, room temperature
• 100 ml dark rum (plus extra for soaking)
• 80 ml pineapple juice
• 1 tsp baking powder
• ½ tsp salt
• 80 g unsalted butter, melted

Pineapple Frosting

• 250 g cream cheese, softened
• 120 g powdered sugar, sifted
• 60 ml pineapple puree
• 1 tbsp rum‑infused simple syrup
• 1 tsp vanilla extract
• Pinch of sea salt

Optional Garnish

• Fresh pineapple wedges
• Toasted coconut flakes
• Edible gold leaf for extra sparkle

Step‑by‑Step Instructions

1. Preheat & Prepare: Set the oven to 175 °C (350 °F). Grease a 23 cm (9‑inch) round cake pan, line the base with parchment, and lightly dust with flour.
2. Mix Dry Ingredients: In a medium bowl whisk together flour, baking powder, and salt. Set aside.
3. Whisk Eggs & Sugar: Using a stand mixer on medium speed, beat the eggs and granulated sugar until the mixture triples in volume and turns a pale, fluffy yellow (about 5‑7 minutes).
4. Incorporate Liquids: Gently fold in the melted butter, rum, and pineapple juice until just combined. Avoid over‑mixing to keep the batter airy.
5. Combine Wet & Dry: Using a spatula, fold the dry flour mixture into the batter in three additions, ensuring a smooth, homogenous batter without streaks.
6. Bake the Sponge: Pour the batter into the prepared pan, smooth the top, and bake for 28‑32 minutes, or until a toothpick inserted in the center emerges clean. Rotate the pan halfway for even browning.
7. Rum Soak (Optional but Recommended): While the cake cools on a wire rack, whisk together 2 tbsp of dark rum with 1 tbsp of pineapple juice. Poke the cake lightly with a skewer and brush the rum mixture over the surface, allowing it to soak in.
8. Prepare Frosting: In a large bowl, beat the cream cheese until smooth. Add powdered sugar gradually, then fold in pineapple puree, rum‑infused simple syrup, vanilla, and a pinch of sea salt. Beat until light and fluffy (about 2 minutes).
9. Assemble the Cake: Place the cooled sponge on a serving plate. Spread a generous layer of pineapple frosting over the top, then gently roll the cake onto a turntable and frost the sides, smoothing with an offset spatula.
10. Garnish & Serve: Decorate with fresh pineapple wedges, toasted coconut flakes, or a drizzle of rum‑infused caramel. Slice with a hot, wet knife for clean cuts, and serve at room temperature.

Pro Tips & Tricks

• Room‑temperature ingredients: Eggs, butter, and pineapple juice should be at room temperature to ensure a uniform batter and maximum rise.
• Don’t over‑beat: Once the flour is added, mix just until incorporated. Over‑mixing develops gluten, resulting in a dense cake.
• Rum infusion tip: Use dark rum for depth of flavor; if you prefer a milder taste, substitute with aged white rum.
• Frosting consistency: If the frosting is too soft, chill it for 10‑15 minutes before spreading. If too firm, add a splash of pineapple juice.
• Even frosting: Warm the spatula under hot water, dry it, and glide it over the cake for a perfectly smooth finish.

Variations & Substitutions

The beauty of this cake lies in its adaptability. Below are some creative twists to suit dietary needs or flavor cravings:

• Gluten‑Free: Replace all‑purpose flour with a 1:1 gluten‑free flour blend and add ½ tsp xanthan gum.
• Vegan: Substitute eggs with ¼ cup aquafaba (chickpea liquid) whipped to stiff peaks; use coconut oil for butter and a plant‑based cream cheese alternative.
• Tropical Boost: Add ¼ cup finely chopped fresh mango or passion‑fruit pulp to the batter for extra fruit texture.
• Spiced Rum Version: Swap dark rum for spiced rum and sprinkle a pinch of ground cinnamon into the frosting.
• Low‑Sugar: Use ⅔ of the powdered sugar and replace the remaining sweetness with a natural sweetener like erythritol, adjusting to taste.

Storage Tips

This cake stays fresh and moist for up to 4 days when stored properly. Follow these guidelines:

• Cover the cake loosely with a dome lid or parchment‑lined foil to prevent the frosting from drying out.
• Store at room temperature if you plan to serve within 48 hours; for longer storage, refrigerate (the frosting may firm up, so let it sit at room temperature 20 minutes before serving).
• For extended keeping, slice and freeze individual portions in airtight bags for up to 2 months. Thaw overnight in the fridge and bring to room temperature before frosting.
