Old fashioned buttermilk blueberry muffins are super moist and have a sweet berry flavor with just a touch of vanilla. Buttermilk keeps these classic gems tender and delicious!
Put paper or silicone liners in muffin cups or spray with baking release spray.
Combine remaining 1-¾ cups flour, sugar, baking powder, and salt in a bowl.
Stir in buttermilk, egg, butter, and vanilla extract.
Fold in the floured blueberries and any remaining flour with them.
Spoon into muffin cups.
Sprinkle a little white sugar on the tops if desired.
Bake for 20-25 minutes or until a wooden pick inserted in center comes out clean. Muffins will read 209℉-210℉ when tested with an instant read thermometer when done.
Cool in pans for 5 minutes.
Turn out to cool completely or serve.
