Preheat your oven to 350°F (175°C) and grease a bundt pan.

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

Cream butter and sugar in a large bowl until light and fluffy (about 5 minutes).

Add eggs one at a time, mixing well after each addition, then stir in the dark rum.

Gradually add the dry ingredients alternately with milk until just combined—do not overmix.

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

While cooling slightly, prepare the glaze by whisking powdered sugar with rum until smooth.

Poke holes in the cake and drizzle with glaze before serving.
