A rich, impossibly moist cake infused with rum and bathed in a buttery rum glaze, based on a traditional recipe from a Cajun lady in New Orleans. This cake gets better with age!
Place the remaining cake ingredients in the bowl of a stand mixer or a large mixing bowl. Mix on low speed to combine. Then beat for 4 minutes at medium speed.
Pour the batter into the bundt pan and bake for 1 hour, until the cake begins to pull away from the pan. Do not underbake.
Remove from the oven and let cool in the pan for 20 minutes. Remove the cake from the pan and place on a wire rack.
While the cake is still warm, make the glaze: Combine the butter, sugar, and water in a saucepan over medium heat. Stir until the mixture comes to a boil. Boil for 5 minutes, stirring constantly. Add the rum and return to a boil.
