Moist and light with a sugary crusted top, these muffins are bursting with blueberry goodness. The acidity from the buttermilk breaks down the gluten strands in the flour producing a beautifully tender crumb.
1Sift the flour and baking powder together and set aside.
2Whisk the buttermilk and oil together and set aside.
3Place the butter in the bowl of a bench mixer and beat on high speed for 2 minutes or until softened. Add the sugar, salt and vanilla and beat for 4 minutes or until pale and creamy, scraping down the side of the bowl.
4Reduce the speed to medium and add the eggs one at a time, beating well between each addition.
5Reduce the mixer speed to low and add a third of the flour mixture followed by half the buttermilk mixture and then repeat until all the buttermilk mixture and flour is incorporated.
6Remove the bowl from the mixer and gently fold in the blueberries.
7Insert the wire rack into position 6.
8While preheating, line a standard 12-cup muffin pan with paper liners. Place about 1/3 cup of the batter into each liner. Sprinkle with the turbinado sugar to create a crispy top.
9Once preheated, place the pan in the oven and start the timer. Cook until a skewer inserted into the center of a muffin comes out clean.
10Allow the muffins to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
11Muffins are best eaten the day they are made but will keep in an airtight container for up to 3 days at room temperature or frozen for up to 3 months.
