Preheat your oven to 325°F (160°C) and grease a bundt pan.

In a bowl, whisk together flour, baking powder, and salt.

In another bowl, cream softened butter and sugar until light and fluffy.

Beat in eggs one at a time, then stir in vanilla extract.

Gradually add dry ingredient mixture to wet ingredients while alternating with milk until smooth.

Gently fold in dark rum until fully combined.

Pour batter into prepared bundt pan and bake for about 50-60 minutes or until a toothpick comes out clean.
