3 stars because at its core, the recipe is good... but jeez Grandpa! Ease up on the rum! I used 1/8 c of rum and thought any more would have been too much.
The frosting has a great texture but we found it just has too much rum (we used Myers Dark) in it for us to work well with the suggested cake (Grandpa's Chocolate-Rum Cake.) We dipped strawberries into the extra frosting and preferred it this way. I can imagine using this recipe to thinly frost a moist tart flavored cake or perhaps a spice cake.
