This old-fashioned blueberry coffee cake is moist, rich and topped with an irresistible crumb topping. For the best flavor, make sure you use fresh blueberries.
Crumb Topping:
1/2 cup all-purpose flour
1/4 cup plus 2 tablespoons (packed) dark brown sugar
1/2 teaspoon kosher salt
1/4 cup pecans, toasted, chopped
3 tablespoons chilled unsalted butter, cut into 1/4-inch cubes
Cake:
Nonstick vegetable oil spray
1 1/2 cups all-purpose flour
1 tablespoon cornmeal
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon kosher salt
3/4 cup plus 3 tablespoons sugar, divided
6 tablespoons (3/4 stick) unsalted butter, room temperature
1/2 teaspoon vanilla extract
2 large eggs
1 cup buttermilk
1 tablespoon ground cinnamon
2 cups fresh (or frozen, thawed) blueberries (about 10 ounces)
1 tablespoon panko (Japanese breadcrumbs)
Crumb Topping:
Whisk flour, sugar, and salt in a medium bowl. Stir in nuts. Add butter; using your fingertips, work butter into dry ingredients until large, moist crumbs begin to form. Set topping aside. DO AHEAD: Can be made 5 days ahead. Cover and chill.
Cake:
Preheat oven to 350°. Coat pan with nonstick spray. Line bottom with parchment paper; set aside. Whisk flour, cornmeal, baking powder, baking soda, and salt in a medium bowl; set aside.
Using an electric mixer on medium speed, beat 3/4 cup sugar and butter in a medium bowl until light and fluffy, 3-4 minutes. Beat in vanilla. Add eggs one at a time, beating to blend between additions and occasionally scraping down sides of bowl, until mixture is pale and fluffy, 3-4 minutes longer.
With mixer on low speed, add dry ingredients to bowl in 3 additions, alternating with buttermilk in 2 additions, beginning and ending with dry ingredients. Pour half of batter into prepared pan and smooth top. Whisk remaining 3 Tbsp. sugar and cinnamon in a small bowl; sprinkle evenly over batter in pan. Spoon remaining batter over; smooth top.
Toss blueberries with panko in a small bowl; scatter evenly over batter. Sprinkle crumb topping over blueberries.
Bake cake until top is golden brown and a tester inserted into the center comes out clean, 55-65 minutes. Let cool completely in pan. DO AHEAD: Can be made 1 day ahead. Store airtight at room temperature.
