Made a few additions to the ingredients. . .
Added 2 tbsps of unsweetened coconut flakes, and 1 TBSP coconut nectar, as well as vanilla powder in addition to the extract. Only used 3 bananas because that's all I had, and 2 cups whole wheat pastry flour. Used allspice and cinnamon in addition to the ginger, and juice of 1/2 a lime, and used a coconut/canola oil blend for the oil. Amazing!!!! Just add the extra bake time--this will not be cooked through in 50 minutes.
Pros: Deep and rich flavor from the coffee
Cons: Needs at least 20 additional minutes to fully bake in loaf pan!
