I used vanilla as my flavor today. However, you can use Nutmeg, Cinnamon, Allspice or any other flavor of your choice.
As much as you want to add a type of flavor to your cake, these flavors should compliment the cake and not overwhelm it. Therefore, add just enough flavor and don’t mask the plantain taste in your Cake.
As much as you want to make sure the plantain is well mashed, it is best to leave it thick and lumpy. Try not to puree it. You can use a hand mixer like I did, it will do the job just fine. Likewise, you can use a Potato masher or fork but I will advise against blending it.
Don’t over mix the batter otherwise, the cake will come out tough.
