Prepare the wet ingredients. Peel the bananas and mash them with a fork and place them in a large mixing bowl. Add the rest of the wet ingredients – milk, coconut oil, eggs and agave syrup – and whisk until everything is incorporated.
Prepare the dry ingredients. Mix all the dry ingredients - wholewheat flour, baking powder and flaxseed meal - together in a large bowl.
Add the dry ingredients to the wet ingredients and join together with a whisk or spatula.
Fold into the mixture in ¾ of the chocolate chips with a spatula (the rest will be used to sprinkle on top).
Prepare the bread pan. Line a loaf pan with some parchment paper or grease it a bit with coconut oil and transfer the batter into the loaf pan (you don't have to use a parchment paper if you have a non-toxic nonstick loaf pan like this amazing glass Pyrex).
Decorate with some chopped hazelnuts and the rest of the chocolate chips.
Bake for 50 - 60 minutes: based on the strength of your oven. When you insert a knife or toothpick through the bread it should come out clean.
Cool and serve. Take out of the loaf pan and allow to cool on a cooling rack.It tastes incredible just warm, about 10-15 minutes after it came out of the oven.
