Ingredients

For the Topping

  • 6 tablespoons granulated sugar
  • 1/4 cup dark-brown sugar
  • 1 teaspoon cinnamon

For the Cupcakes

  • 1 2/3 cups cake flour (not self-rising)
  • 1/4 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 stick unsalted butter, softened
  • 2/3 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 3/4 cup sour cream
  • 6 ounces blueberries (1 1/4 cups)

For the Icing

  • 1 1/4 sticks unsalted butter, softened
  • 8 ounces cream cheese, room temperature
  • 1/2 teaspoon pure vanilla extract
  • 2 2/3 cups confectioners' sugar, sifted
  • 1/4 cup high-quality blueberry jam, such as Hero, strained (3 tablespoons)

Directions

  1. Make the topping: Mix together granulated and brown sugars and cinnamon.

  2. Make the cupcakes: Preheat oven to 375 degrees with rack in upper third of oven. Line cups of a standard muffin tin with baking cups. Sift together flour, baking soda, baking powder, and salt. Beat together butter and granulated sugar with a mixer on medium-high speed until pale and fluffy, 2 to 3 minutes. Beat in eggs, 1 at a time, then beat in vanilla, scraping down sides of bowl. Reduce speed to low, and beat in flour mixture in 3 additions, alternating with sour cream and beginning and ending with flour. Fold in blueberries.

  3. Divide batter among baking cups. Add topping, pressing to adhere to batter. Bake until golden and a toothpick inserted in center comes out with moist crumbs attached, 20 to 21 minutes. Remove cupcakes from tin, and let cool completely on a wire rack.

  4. Make the icing: Beat together butter and cream cheese with a mixer on medium-high speed until pale and fluffy, about 2 minutes. Reduce speed to low, and gradually beat in vanilla and confectioners' sugar. Raise speed to medium-high, and beat 1 minute. Spoon jam on top of icing, and without stirring, spoon icing into a disposable pastry bag. Snip off a 3/4-inch opening in tip, and pipe swirled mounds of icing on top of each cupcake. Although best if eaten immediately, cupcakes can be refrigerated up to 6 hours and brought to room temperature 45 minutes before serving.
