2cupsall purpose flour(fluffed and levelled, 260g)
1cupsemisweet chocolate chips
Preheat oven to 350 degrees F and lightly grease an 8x4" loaf pan (larger is fine, but you will want to reduce the cook time by 10-15 minutes).
Mash bananas in a large bowl with a fork or a whisk.
Add sugar, sour cream, applesauce, eggs and vanilla and whisk until completely combined.
Add flour, baking powder, cinnamon, baking soda and salt and stir just until all flour is moistened (no white streaks).
Stir in chocolate chips and spread into prepared loaf pan. Bake for 50-65 minutes, covering with foil at the 40 minute mark if desired (to prevent further browning), or until a toothpick inserted in the center comes out clean.
Let cool in pan on a wire rack for 15 minutes, then carefully remove from the pan to cool completely (or to serve warm!).
