Ingredients List
- 2 ½ cups all-purpose flour
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup unsalted butter (room temperature)
- 2 cups granulated sugar
- 4 large eggs (room temperature)
- 1 cup buttermilk
- ½ cup dark rum
- 2 teaspoons pure vanilla extract
- 1 cup chopped walnuts or pecans (optional)
For the Rum Syrup:
- ½ cup unsalted butter
- ¾ cup granulated sugar
- ¼ cup water

Step-by-Step Instructions

Step 1: Prepare the Pan
Preheat oven to 170°C (340°F). Grease and flour a Bundt pan thoroughly, ensuring all edges and grooves are well coated. Add chopped nuts evenly if using.
Step 2: Combine Dry Ingredients
Whisk together flour, baking powder, baking soda, and salt in a bowl. Proper mixing at this stage ensures even leavening.
Step 3: Cream Butter and Sugar
Beat butter and sugar until pale and fluffy. Incorporating air here is essential for a light, tender crumb.
Step 4: Add Eggs
Incorporate eggs one at a time, mixing well after each addition to maintain a smooth, stable batter.
Step 5: Mix Liquid Ingredients
In a separate bowl, combine buttermilk, rum, and vanilla extract. Blend well for even distribution of flavor.
Step 6: Build the Batter
Add dry ingredients to the butter mixture in portions, alternating with the liquid mixture. Begin and finish with dry ingredients. Mix gently to avoid overworking the batter.
Step 7: Bake the Cake
Transfer batter to the prepared pan and level the surface. Bake for 55–65 minutes until a skewer inserted into the center comes out clean.
Step 8: Prepare the Syrup
Heat butter, sugar, and water in a saucepan over medium heat. Stir until dissolved and slightly thickened. Remove from heat and carefully add rum.
Step 9: Infuse the Cake
Allow the cake to cool slightly. Pierce small holes across the surface and slowly pour the warm syrup, allowing full absorption.
Step 10: Cool and Unmold
Let the cake cool completely before removing from the pan. Proper cooling helps the structure set and enhances moisture retention.

FAQs
1. How can a stronger rum flavor be achieved without affecting texture?
Increasing rum in the syrup rather than the batter enhances flavor without altering the cake’s structure. Brushing additional syrup onto slices before serving also intensifies the taste.
2. What causes a rum cake to stick to the pan?
Insufficient greasing or missing flour coating often leads to sticking. A well-prepared pan, especially with detailed grooves like a Bundt, ensures clean release.
3. Is it possible to make the cake ahead of time for an event?
Yes, rum cake actually improves in flavor after a day as the syrup fully absorbs. Preparing it a day in advance often results in better taste and texture.
