How can I incorporate alcohol (rum, in this case) into an existing cake recipe (pumpkin cake, for example)? Can I simply replace the water with rum?

    Can you give some more information about the recipe (or even link to it)? The amount of water and the density of the cake might have some effect on answers. (But in general water -> liquor is a fairly safe substitution, I think.)

  • Alcohol evaporates much more quickly than water, and rum is about 40% alcohol. So a straight substitution might cause problems. But it depends on the recipe. I have no idea what kind of cake you're making. Commented Nov 20, 2011 at 5:19

You can also try, rather than putting it in during the baking process, to pour the rum into a pan big enough to fit te cake or loaf and have it soak up the alcohol. Additionally, rum is a very strong flavour, and might overpower or conflict with the pumpkin, so be careful not to use too much or you might end up with pumpkin flavoured rum cake as opposed ot rum hinted pumpkin cake.


If you're using around 3-cups of flour 1/4 cup of rum is definitely safe to use. Not knowing the recipe, and just in case there are other liquids, just adjust them to incorporate the rum so measurements stay equal. Cheers!


If I just want to add aroma to the cake, I just add a small amount to the batter. If I have an ingredient like dried fruit or raisins in the cake, I might soak them in rum for a couple of hours before incorporating into the batter. If I want an actual boozy flavor, pouring a modest amount over a baked cake, while still in the pan, will allow it to absorb more. Finally, you can make an icing or glaze from a mix of powdered (confectioner's) sugar and liquor instead of water.
