Pop your oven to 375°F (190°C) and get a muffin pan ready. Use liners or grease it with spray so nothing sticks.

Grab a bowl and stir together the flour and baking powder. If you're skipping salted butter, add a pinch of salt here.

In a big bowl, beat melted butter, brown sugar, and eggs till smooth. Stir in the milk, vanilla, and rum until everything blends nicely.

Pour the dry mix little by little into the wet mix. Gently fold them together with a spatula. Stir in chips once barely combined—it'll be chunky and thick.

Scoop 4 tablespoons of batter into each muffin cup. Sprinkle some extra chips or sugar on top if you feel fancy. Bake for 20 to 24 minutes, or until a toothpick test shows a mostly clean result.

Give the muffins 5–10 minutes in their pan before cooling totally on a rack. They taste great warm or at room temp! Add a butter glaze if you like.
