Blueberry Coffee Cake Muffins

12 tablespoons (1 1/2 sticks) unsalted butter, at room temperature
1 1/2 cups sugar
3 extra-large eggs, at room temperature
1 1/2 teaspoons pure vanilla extract
8 ounces (about 1 cup) sour cream
1/4 cup milk
2 1/2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon kosher salt
2 half-pints fresh blueberries, picked through for stems

Preheat the oven to 350 degrees. Line 16 paper liners in muffin tins.

In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar until light and fluffy, about 5 minutes. With the mixer on low speed, add the eggs 1 at a time, then add the vanilla, sour cream, and milk. In a separate bowl, sift together the flour, baking powder, baking soda, and salt. With the mixer on low speed add the flour mixture to the batter and beat until just mixed. Fold in the blueberries with a spatula and be sure the batter is completely mixed.

Bake the muffins for 25 to 30 minutes, until golden brown.
