3. Combine Wet Ingredients: In another bowl, mix the melted butter, milk, eggs, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients, stirring gently until just combined. Avoid over-mixing.
5. Fold in Blueberries: Carefully fold in the blueberries until evenly distributed throughout the batter.
6. Fill Muffin Tins: Spoon the batter into the prepared muffin tin, filling each cup about two-thirds full to allow room for rising.
7. Bake: Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
