½ cup butter, softened
1 ¼ cups sugar
2 eggs
1 tsp vanilla extract
2 cups flour
½ tsp salt
2 tsp baking powder
1 tsp cinnamon
½ cup milk
2 cups blueberries, washed, drained and picked over
3 tsp sugar

1. Preheat the oven to 375. Grease muffin pan with non-stick cooking spray.
2. Use a hand-mixer to cream* butter and sugar until light. (*To cream butter without a mixer: use the tines of a fork to mash sugar into butter. With a spoon, stir mixture until light and fluffy. The butter is “creamed” when it has almost doubled in mass and it has lightened to a yellowish-white color.)
3. Add the eggs, one at a time, and mix well. Add vanilla.
4. In a separate large mixing bowl, combine flour, salt, baking powder and cinnamon.
5. Add creamed mixture and milk to the flour mixture and mix until combined.
5. Crush 1 cup blueberries with a fork, and mix into the batter.
6. Coat remaining whole berries with flour and then fold them into the batter.
6. Distribute batter into each muffin cup. Sprinkle the 3 teaspoons sugar over the tops of the muffins, and bake at 375 degrees for about 30 minutes.
7. Remove muffins from tin and cool at least 30 minutes. Store, uncovered, or the muffins will be too moist the second day, if they last that long.
