Preheat your oven to 375°F (190°C) and prepare your muffin tin by greasing it or lining it with paper liners.

Whisk together the flour, sugar, baking powder, and salt in a mixing bowl until fully combined.

Mix the melted butter with eggs and milk in a separate bowl until the mixture becomes frothy.

Combine the wet and dry ingredients gently, taking care not to overmix. Fold in the blueberries with love.

Fill each muffin cup about two-thirds full with the batter and bake for 18-20 minutes, or until they turn golden brown.

Cool them slightly before serving.
