Preheat your oven to 350°F (175°C) and prepare a greased 9 x 5 loaf pan.

In a medium bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt.

In a large bowl, mix ½ cup canola oil, ½ cup granulated sugar, and ½ cup brown sugar. Add 2 eggs and 1 teaspoon vanilla extract, whisk until smooth.

Stir in 3 well-mashed bananas until fully incorporated.

Gently fold the dry ingredients into the wet mixture until just combined.

Toss 1 cup blueberries in a tablespoon of flour and fold them into the batter without crushing.

Pour the batter into the prepared loaf pan and bake for approximately 60 minutes.

Allow to cool in the pan for about 20 minutes, then transfer to a wire rack to cool completely before slicing.
