Beat together the butter and the sugar with eclectic mixers for about 3-4 minutes or until it becomes light and fluffy .
Gradually add the rum , one tablespoon at a time , until well combined , add more rum if desired .
Pour the rum butter into a serving dish , cover and refrigerate until required .
Serve over anything you desire .
Enjoy .

To turn it into a runny sauce , don't blend the butter and sugar with mixers , instead place them into a small saucepan over low heat till butter and sugar has melted , then remove from the heat , let cool , then add the rum and stir to combine .
