Preheat the oven to 350°F (175°C). Grease your mini loaf pans or line them with parchment paper.
Mash the bananas until mostly smooth.
Add the brown sugar, vegetable oil, and vanilla extract. Mix until well combined.
In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt.
Add the dry ingredients to the banana mixture and gently stir until just combined. Be careful not to overmix.
Lightly stir in the dairy-free mini chocolate chips.
Divide the batter evenly between the prepared mini loaf pans.
Bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean.
Let the mini loaves cool in the pans for a few minutes before transferring them to a wire rack to finish cooling.
