2 cups all-purpose flour
1 and ½ tsp baking powder
¼ tsp baking soda
1 tsp salt
6 oz. fresh or frozen blueberries
¾ cup buttermilk (or regular milk + 1/2 tsp vinegar, stir and let sit 5 minutes)
1 tsp vanilla extract
¼ cup vegetable or canola oil
1 large egg, slightly beaten
1 cup granulated sugar
Line a 9" x 5" loaf pan with aluminum foil. Butter the bottom and sides of the foil. Set aside.
Preheat the oven to 375 degrees F.
In a large mixing bowl, whisk together flour, baking powder, baking soda and salt.
Add blueberries and stir to distribute.
In another mixing bowl, whisk together egg, buttermilk, vanilla, oil and sugar.
With a rubber spatula, fold in wet ingredients to dry ingredients. Do not overmix. Few flour lumps are okay.
Pour batter into prepared pan.
Bake bread for 33 to 38 minutes, or until the top is golden brown and the toothpick inserted in few places in the center of the cake comes out clean.
Cool most of the way in the pan.
Slice and serve.
