Preheat the oven to 375°F (190°C). Line a muffin tin with paper liners or grease it.
In a large bowl, whisk together flour, sugar, baking powder, and salt.
In a separate bowl, combine melted butter, milk, eggs, and vanilla extract.
Pour the wet ingredients into the dry ingredients and stir until just combined.
In a small bowl, toss the blueberries with 1 tablespoon of flour to prevent them from sinking to the bottom. Gently fold the blueberries into the batter.
Divide the batter evenly into the muffin tin, filling each cup about ⅔ full.
Bake for 18-20 minutes or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for a few minutes, then transfer to a wire rack to cool completely.

Serving Suggestions: Serve warm with a drizzle of honey or a dollop of whipped cream for a special treat. Pair with your favorite morning beverage for a perfect breakfast.
Allergy-Friendly Options: For a dairy-free version, substitute the butter with coconut oil and use almond or oat milk instead of regular milk.
