Preheat & Prep: Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
Mix Dry Ingredients: In a large mixing bowl, whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon.
Add Wet Ingredients: Make a well in the center or use a large measuring cup and add milk, oil, eggs, and vanilla. Stir until just combined—don’t overmix!
Toss & Fold Blueberries: In a small bowl, toss blueberries with 1 tablespoon of flour (this helps prevent them from sinking) and one teaspoon of sugar (to balance out the tartness). Gently fold them into the batter.
Bake: Pour batter into the prepared loaf pan and bake for 55-65 minutes or until a toothpick inserted in the center comes out clean.
Cool & Enjoy: Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Slice and savor!
