Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.
In another bowl, mix the almond milk, vegetable oil, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Fold in the blueberries gently.
Pour the batter into the prepared loaf pan.
Bake for 60 minutes or until a toothpick inserted into the center comes out clean.
Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
