These cookies are no more difficult to make than normal cookies. Simply beat softened butter and sugar together in a large bowl. Mash the banana together with the bicarbonate of soda and leave for a few minutes for it to work its magic.
Mix together the banana and sugar mixture until well combined and then mix in the flour. Finally, stir in the chocolate chips and your mixture is ready to go. Drop blobs on a baking tray lined with parchment paper and flatten lightly with the back of a spoon to make disk shapes. Pop into a preheated oven for 12 minutes and voila! Delicious soft banana cookies.
