Here you go DMC. I don't know that it's any different from other berry muffin recipes, but this one worked well for me.
Blueberry Muffins
(makes 6 jumbo or 12 regular size)
2 1/2 Cups AP four
1 teaspoon baking soda
3/4 Cup sugar
1/2 teaspoon salt
2 eggs
1 Tablespoon lemon juice
1 Cup buttermilk
4 oz. butter (a stick), melted
1 1/2 Cups blueberries, fresh or frozen
* Preheat oven to 400*.
* Whisk dry ingredients together in a large bowl.
* In another bowl, whisk eggs, lemon juice, buttermilk and butter.
* Stir wet and dry ingredients together just until combined (do not over mix)
* Fold in blueberries.
* Spoon batter into greased muffin pans (I used no-stick spray) and bake until golden brown. About 20-30 minutes or until a toothpick inserted in the middle comes out clean.
* Cool on a wire rack for about 10 minutes, then remove the muffins from the pan and let cool completely.
