2 cups flour
1 tablespoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1 egg
2 teaspoons good vanilla
3/4 cup sugar
4 tablespoons melted butter
1-1/2 cups milk
2 cups blueberries (I used frozen but can use fresh if you have them)

Preheat the oven to 350 degrees Fahrenheit, and grease a muffin pan with some baking spray.

In a large mixing bowl, whisk egg, sugar, melted butter and milk. Stir in the flour, salt, baking powder and baking soda. Whisk together until smooth.

Whisk in the vanilla. Fold in blueberries.

Fill the muffin cups 3/4 full with batter and bake for 30 to 35 minutes or until done using toothpick to test.
