Ingredients

• Ingredients – Cake
• All-purpose flour: 2 ½ cups (300g)
• Granulated sugar: 1 ½ cups (300g)
• Light brown sugar: ½ cup (100g), packed
• Baking powder: 2 teaspoons
• Fine sea salt: 1 teaspoon
• Unsalted butter: 1 cup (226g), softened
• Neutral oil (like vegetable or canola): ¼ cup (60ml)
• Large eggs: 4, at room temperature
• Whole milk or buttermilk: 1 cup (240ml), at room temperature
• Dark or gold rum: ½ cup (120ml)
• Vanilla extract: 2 teaspoons
• Optional: Almond extract: ½ teaspoon (for extra depth)
• Why these ingredients matter:
• Butter and Oil Combo: Using both butter and oil gives us the best of both worlds – the rich flavor of butter and the unbeatable moisture and tender crumb that oil provides. It’s our secret to a super moist cake without any boxed mixes.
• No Pudding/Cake Mix: We're skipping the processed stuff! Our carefully balanced blend of sugars, butter, and oil, along with the right amount of leavening, ensures a naturally soft, fine crumb that stands up beautifully to the rum soak.
• Dark/Gold Rum: These rums bring deeper, more complex caramel and molasses notes that are essential for that classic caribbean rum cake flavor. White rum would be too sharp, and spiced rum might overpower the cake's natural taste (though it's a fun variation!).
• Ingredients – Rum Syrup
• Granulated sugar: 1 cup (200g)
• Water: ½ cup (120ml)
• Unsalted butter: ½ cup (113g)
• Dark or gold rum: ¾ cup (180ml)
• Vanilla extract: 1 teaspoon
• Pinch of fine sea salt
• Syrup Texture Goal: We're aiming for a syrup that's thick enough to cling to the cake but still pourable, not a sticky caramel. It should be syrupy, not gloopy!
• Optional Add-Ins (Brief Only)
• Chopped pecans or walnuts: ½ cup, for sprinkling in the bottom of the bundt pan.
• Finely shredded coconut: ½ cup, either mixed into the batter for a subtle coconut flavor or sprinkled on top after the cake is soaked.
• Extra citrus zest: 1 tablespoon (orange or lime) for a brighter, more zesty Caribbean personality.

Directions

1. Prep Checklist:
   1. Bring your butter, eggs, and milk to room temperature. This helps everything emulsify smoothly for a tender cake.
   2. Grease and flour your bundt pan very thoroughly. Don't skip this critical step!
   3. Move an oven rack to the middle position.
   4. Preheat your oven to the correct temperature.
   5. Clear a space where your cake can rest undisturbed overnight after soaking – the longer it rests, the better it gets!
2. Prepare the Pan & Oven
3. Preheat Oven: Get your oven heating to 325°F (160°C).
4. Grease Your Bundt Pan: This is crucial! Use butter or shortening to grease a 10–12 cup bundt pan meticulously, making sure to get into every single ridge and crevice. Then, lightly flour the pan, tapping out any excess. For extra insurance, you can use baking spray with flour, or even dust with fine breadcrumbs, almond flour, or a little sugar instead of flour.
5. Add Nuts (Optional): If you're using chopped pecans or walnuts, sprinkle them evenly into the bottom of the prepared bundt pan.
6. Make the Cake Batter
7. Combine Dry Ingredients: In the bowl of a stand mixer (or a large bowl with a hand mixer), whisk together the all-purpose flour, granulated sugar, brown sugar, baking powder, and fine sea salt.
8. Add Fats: Add the softened unsalted butter and neutral oil to the dry ingredients. Mix on low speed until the mixture resembles coarse, sandy crumbs. It should look like wet sand!
9. Incorporate Liquids & Eggs: In a separate measuring cup, whisk together the room-temperature milk (or buttermilk) and eggs. With the mixer on low, gradually add about half of the milk mixture to the sandy flour mixture, mixing until just combined. Scrape down the sides of the bowl. Add the remaining milk mixture and mix until just incorporated.
10. Add Flavorings: Finally, mix in the dark or gold rum, vanilla extract, and optional almond extract. Mix only until everything is just combined and no streaks of flour remain.
11. Do not overmix! Overmixing develops gluten, which can lead to a tough cake. The final batter should be thick but pourable.Bake the Cake
12. Fill Pan: Pour the cake batter evenly into your prepared bundt pan. Gently tap the pan on the counter a few times to release any air bubbles and level the top.
13. Bake: Bake for 60–70 minutes. The cake is done when:
    1. A long skewer or toothpick inserted into the thickest part comes out clean or with a few moist crumbs attached.
    2. The edges of the cake have pulled slightly away from the sides of the pan.
    3. The top is light golden brown and springs back lightly when gently touched.
14. Check Early: Ovens vary, so start checking for doneness around 55 minutes. If the center still looks wet or wobbly, continue baking in 5-minute increments.
15. Make the Rum Syrup
16. Simmer Syrup Base: While the cake is baking (or immediately after it comes out of the oven), combine the granulated sugar, water, and unsalted butter in a small saucepan over medium heat. Bring to a simmer, stirring until the sugar is dissolved and the butter is melted.
17. Thicken Slightly: Continue to simmer for 3-5 minutes, until the syrup thickens slightly. You'll notice the bubbles become a bit larger and the syrup will coat the back of a spoon.
18. Add Rum & Vanilla: Remove the saucepan from the heat. Carefully stir in the dark or gold rum, vanilla extract, and pinch of salt.
19. Safety Note: Be mindful of steam and alcohol fumes; keep your face away from the pan.
20. Avoid Caramel: Don't reduce the syrup for too long, or it will become too thick and sticky, turning into a caramel rather than a pourable syrup.
21. Soak the Warm Cake
22. Poke Holes: As soon as the cake comes out of the oven, while it's still warm in the bundt pan, use a long skewer or chopstick to poke many deep holes all over the top surface of the cake. Go deep, but be careful not to scrape the bottom of the pan.
23. Pour Syrup in Stages: Slowly pour the warm rum syrup over the cake, a little at a time. Let each pour soak in completely before adding more. This allows the cake to absorb all that delicious boozy goodness without becoming oversaturated or soggy. The syrup should almost disappear between pours.
24. Why in Stages? Rushing the pour will cause the syrup to pool on top or run off the sides, preventing even absorption. Patience here results in a perfectly moist, rum-drenched cake.
25. Rest, Unmold & Serve
26. Rest the Cake: Once all the syrup has been absorbed, cover the bundt pan lightly with aluminum foil or plastic wrap. Let the cake rest at room temperature for a minimum of 4 hours.
27. Ideal Rest: For the absolute best flavor and texture, let the cake rest overnight (8–12 hours). This allows the rum flavor to mellow and deepen, and the crumb to fully set and absorb the syrup.
28. Unmold: After resting, gently run a thin, flexible spatula or knife around the inner and outer edges of the bundt pan to loosen the cake, if needed. Place a serving plate or wire rack over the top of the pan, then carefully invert the cake onto the plate. Give it a gentle shake; if it's stuck, you can briefly warm the bottom of the pan in a warm oven (turned off) for a few minutes, then try again.Serving Suggestions: Slice and serve your caribbean rum cake plain, with a dollop of whipped cream, or a scoop of vanilla ice cream. Note that slices will be beautifully moist and slightly sticky from the rum syrup. Enjoy!
