Amazing Bacardi Rum Cake

This is the iconic 1970s Bacardi rum cake recipe that ran on the back of yellow cake mix boxes for two decades. The trick that made it famous is the doctored mix: adding instant vanilla pudding to the dry mix gives the crumb a denser, moister, almost pound-cake structure that holds up to the heavy rum soak.

The Bundt pan and the chopped pecans on the bottom are not optional. As the cake bakes, the nuts toast against the hot pan and become the top crust when you invert. Skip them and you lose the textural contrast that defines this cake.

The glaze is what earns the cake its reputation. Butter, sugar, and water boil into a syrup, then dark rum gets stirred in off heat to preserve its flavor and bite. Pricking the cake all over before drizzling the warm glaze lets the rum syrup soak into every crumb, repeating until the entire glaze is absorbed.

The cake actually gets better on day two. The rum mellows, the crumb fully absorbs the glaze, and the texture sets into something between cake and dense pudding.

Pro Tips

• Use real dark rum, not light or spiced. Dark rum brings the molasses and caramel notes that balance the sweet glaze.
• Grease and flour the Bundt pan thoroughly. The cake sticks easily, especially around decorative ridges.
• Cool the cake at least 15 minutes in the pan before inverting. Too soon and the cake breaks apart; too long and it sticks.
• Use a long skewer or wooden chopstick to prick deep holes throughout. Shallow pricks waste glaze on the surface.

Variations

• Swap pecans for walnuts or skip nuts and dust the pan with cinnamon sugar.
• Use spiced rum and add a teaspoon of cinnamon to the cake mix for a holiday version.
• Serve with a dollop of whipped cream and fresh berries for an upgraded dessert plate.
