Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan.
In a mixing bowl, combine the mashed bananas and melted coconut oil until well blended.
Add in brown sugar, granulated sugar, and mix until fully combined.
Stir in the eggs and vanilla extract, mixing until just incorporated.
In a separate bowl, combine the baking soda, baking powder, salt, cinnamon (if using), and flour.
Gradually add the dry ingredients into the wet ingredients, stirring gently until just combined. Be careful not to overmix!
Fold in the chopped strawberries carefully, ensuring they're evenly distributed in the batter.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake for 60-65 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, let the bread cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
Notes
Slice the banana bread and serve it warm or at room temperature. Consider adding a dollop of whipped cream or a scoop of vanilla ice cream on top for a delightful experience!
