For a while now, I have been trying to experiment with a coffee-flavored cake. Most coffee/espresso flavored cakes usually have the bulk of the flavor coming from the coffee-flavored tiramisu-eque frosting. But what if some coffee is added to the cake itself? Does the flavor transfer over? Intensify?
The answer is - when coffee is added to the cake batter its flavor is bright and great on the palate. However, upon baking, the coffee flavor turns very mild and smoky, and thus hard to discern. So, you do need some form of frosting to impart the coffee flavor. (I tried drizzling some coffee to the freshly baked cake and let it soak in the flavors, but it ruined the texture and consistency of the cake). I'm not sure if adding more coffee to the cake is the solution, or if there is some secret ingredient that will help the coffee retain its composition and flavor while baking. Please let me know if you have any ideas or suggestions!
The cake by itself has a warm and smoky flavor (especially if brown sugar, molasses or honey is added). So, it's definitely worth a try for something different!
