[header] How to flavor cake [title] Use extracts and flavorings. [step] Liquid extracts and flavorings are one of the easiest ways to alter the taste of cake batter since they generally have little effect on the other ingredients, moisture level, or density of the cake. [substeps] Extracts are more concentrated than flavorings, so you should generally use less extract than flavoring. 
Since extracts are more concentrated, however, they typically create richer, more natural tastes. To experiment with different extracts, consider starting with a cake recipe that already contains vanilla extract.
