I want to try making Betty Crocker piña colada cupcakes, but I was curious if I could replace all or some of the ¼ cup of water called for in the recipe with pineapple-coconut rum (35% alcohol by volume). Since the alcohol would have a lower boiling point than the water it would be replacing, I didn’t know if it would mess up the cupcakes. (The recipe calls for yellow cake mix which normally requires 1 cup of water, but juice from a can of crushed pineapples presumably makes up the other ¾ of a cup of water in this recipe.) How much of the ¼ cup of water (if any) can I replace with the rum? Thank you!
