Here is my tweaked version of a recipe I found on Allrecipes.com I have tried many different blueberry muffin recipes and this is my favorite. It tastes most like a bakery muffin to me.... I'm taking these on my Thanksgiving trip.
1/2 cup butter, softened
1 1/14 cups white sugar
2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon cinnamon
1/2 teaspoon salt
1/4 cup milk
2 1/2 cups fresh blueberries
1/4 cup turbinado sugar
Preheat oven to 375 degrees. Grease (REALLY GOOD) muffin pans or use paper liners.
In a large bowl, cram butter and 1 1/4 cup sugar until light and fluffy. Add eggs, one at a time- blending between each addition.
Mix flour, baking powder, cinnamon and salt. Add flour mixture, alternating with milk. Mash 1/2 cup blueberries and stir into batter. Fold in remaining blueberries.
Fill muffin cups and sprinkle with turbinado sugar. Bake at 375 for 25-30 minutes. Remove from oven and wait 20 minutes to remove from muffin pans.
