Buttermilk Blueberry Muffins - cooking recipe

Ingredients

2 1/2 cups all-purpose flour
3/4 cup white sugar
2 teaspoons baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
2 cups fresh blueberries or 2 cups frozen blueberries
1 large egg, lightly beaten
3/4 cup buttermilk
2/3 cup safflower oil or 2/3 cup canola oil
1 teaspoon vanilla extract
Topping
3 tablespoons white sugar
1 tablespoon orange zest, finely chopped (optional)

Preparation

Preheat oven to 375f, grease or line muffin tins, 12 regular, 6 extra large.
Combine flour, sugar, baking powder, baking soda and salt in large bowl. Toss blueberries in flour mixture. In separate bowl combine buttermilk, egg, oil and vanilla extract.
Create a well/crater in the center of the flour mixture, pour the buttermilk mixture into the well/crater. Fold gently, just till ingredients are moist. More mixing will result in tough, chewy muffins.
Spoon batter into muffin tins, filling 2/3 (or more) full. Muffins have a nice crisp top, however, if you'd like a crunchy top, sprinkle with sugar, orange zest mixture.
Bake on centre rack for 20 mins, perhaps longer if using frozen blueberries. Muffins are done when toothpick inserted in center comes out clean. Let cool 5 minutes. Store in sealed container.
