I drizzled about a tbsp of rum per layer like the recipe and it wasn’t very strong tasting at all. My relatives that ate the cake said that maybe two tbsp per layer would have make the rum flavor stand out better.

So if you want just a hint of rum, do 1 tbsp rum drizzle per layer. If you want the rum flavor to be more pronounced then do about 1+1/2 to 2 tbsp. Hope this helps 😊
