Method

Preheat the oven to 200°C and grease or line a muffin tin with paper
liners.

In a medium bowl, whisk together the flour, baking powder and salt.

In a separate bowl mix the butter and sugar for a few minutes until
light and fluffy. Add in the egg and vanilla extract.

Gradually stir in the flour mixture, alternating with the milk until
combined.

Add the blueberries into the batter and fold gently with a spatula until
evenly distributed.

Scoop the batter into the prepared muffin tin.

Bake for about 25-30 minutes or until lightly golden. Let the muffins
cool in the pan for about 10 minutes, then transfer the muffins to a wire rack
to cool completely.
