Imagine the smell and taste of a cake as soon as it's taken out of the oven. That's the flavor of cake e-liquids. There's more of a pastry smell when you open the bottle and a hint of vanilla when you exhale. Set the heat setting to low so that you can enjoy the flavors. There are sweet notes that you can detect, but the liquid is really like tasting cake batter in the mouth that you might eat out of the bowl. This liquid does seem to have a few thicker flavor notes, but using a lower heat setting can sometimes tame them.
